Objective To compare long-term outcomes following mitral valvuloplasty (MVP) and mitral valve replacement (MVR) for native valve endocarditis (NVE). Methods Between November 1993 and August 2016, consecutive 101 patients with NVE underwent mitral surgery in our department, MVP for 52 patients and MVR for 49 patients. There were 69 males and 32 females at age of 38.1±14.9 years. The mean follow-up was 99.4±75.8 months. Results There was no statistical difference in cardiopulmonary bypass time, aortic cross-clamp time, in-hospital mortality, duration of mechanical ventilation, ICU stay or hospital stay after surgery between the two groups. Survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 97.6%, 97.6%, 97.6% for MVP, and 93.5%, 84.3%, 84.3%, 66.2% for MVR with a statistical difference between the two groups (P=0.018). There was no stroke in the patients with MVP during follow-up periods. However, stroke-free survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 93.9%, 89.4%, 70.2% for MVR patients with a statistical difference between the two groups (P=0.023). There was no statistical difference in recurrence of infection, perivalvular leakage and reoperation between the two groups. Composite endpoint-free survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 97.6%, 92.9%, 92.9% for MVP, and 91.3%, 79.6%, 75.8%, 51.0% for MVR with a statistical difference (P=0.006). Conclusion MVP is associated with better outcomes than MVR in the patients with NVE; generalizing MVP technique in the patients with NVE is needed.
ObjectiveTo analyze the long-term efficacy and its influencing factors in the treatment of the permanent atrial fibrillation(AF) using monopolar radiofrequency ablation during concomitant cardiac valve replacement surgery with rheumatic heart disease. MethodsClinical data of the 116 patients with rheumatic heart disease and permanent AF who underwent modified maze procedure using monopolar radiofrequency ablation and concomitant cardiac valve replacement in the affiliated hospital of Qingdao university from October 2004 to December 2010 were collected and retrospectively analyzed, including 43 males and 73 females with their age of 50.5±7.5 years. Electrocardiogram (ECG) with 12-lead and echocardiography data, as well as the related complications, cardiac function and life quality were collected at the time of the immediately after the operation, discharge from hospital, 3 months, 6 months, 1 year postoperatively and every year after the operation. Patients were divided into eliminating group of AF (including sinus rhythm and nodal rhythm) and AF group according to the results of the ECG at the time of the ending follow-up. In the eliminating group of AF, there were 52 patients (16 males, 36 females) with their age of 48.4±7.3 years, and in the AF group, there were 50 patients (22 males, 28 females) with their age of 51.9±7.1 years. Analyzed the difference of the related factors between the two groups using statistical methods and tried to find the factors affecting the long-term clinical efficacy of the operation. ResultsThree patients died in hospital (one died of the hemolysis, acute renal insufficiency and hyperkalemia. One died of the multiple organ dysfunction syndrome caused by the acute renal insufficiency. And the other one died of the multiple organ dysfunction syndrome caused by the repetitive ventricular tachycardia and ventricular fibrillation on the day of the automatic discharge). Three patients died during the follow-up (one died after the reoperation because of the perivalvular leakage in other hospital, and the causes of death in the two others could not be catched). One patient occurred cerebral embolism, and the other one occurred cerebral hemorrhage in the af group during the follow-up. There was statistical significance between two group at the aspects of age, preoperative AF duration, preoperative left atrium diameter, time of the cardiopulmonary bypass and time of the cross-clamp ascending aorta. In multivariate analysis, age and preoperative left atrium diameter are risk factors affecting the long-term efficacy. ConclusionThe treatment of the permanent atrial fibrillation using monopolar radiofrequency ablation concomitant cardiac valve replacement with rheumatic heart disease is effective and has good long-term efficacy. The factors of affecting the long-term clinical efficacy are the patient's age and the diameter of left atrium.
Abstract: Objective To evaluate the longterm results of surgical treatment of tetralogy of Fallot (TOF) in adults and discuss the perioperative treatment skills. Methods From January 2000 to March 2008, 149 patients older than 14 years with tetralogy of Fallot received surgical treatment in Changhai Hospital. Among the patients, there were 78 males and 71 females with ages ranged from 14 years to 53 years and the average age was 26.3 years. Twenty patients had previous pulmonary arterial shunts before radical treatment. A total of 129 patients underwent primary radical treatment. Thirtyeight patients received a right ventricular outflow tract patch, 107 patients had transannular patch, and 4 patients had homograft aorta with valves. Results Hospital mortality was 4.0%(6/149). Four patients died of low cardiac output syndrome (LCOS), and multiple organ failure, and 2 patients died of acute renal failure. The postoperative complications included pleural effusion in 11 patients, pulmonary edema in 10 patients, severe LCOS in 9 patients, severe cardiac arrhythmia in 7 patients, reoperation for excessive bleeding in 7 patients, reintubation in 6 patients, and residual ventricular septal defect (VSD) in 5 patients (two of them had reoperation for residual VSD repair and 2 received transcatheter closure of VSD). One hundred and thirtyfour patients were followed up for 3 to 102 months (47.2±28.6 months) with a followup rate of 93.7%(134/143). Late death occurred in 2 patients, one of whom died of secondary infective endocarditis and the other had a sudden death 29 months after operation. During the followup, one patient had residual VSD (2 mm), but had a normal life. The peak systolic right ventricletopulmonary artery pressure gradient exceeded 40 mmHg in 4 patients. Two patients had severe pulmonary regurgitation. A total of 132 patients survived and had an improved life. One hundred and twentyone patients had class Ⅰ heart function (NYHA), and 11 patients in class Ⅱ. Conclusion The pathophysiologic conditions of the patients with tetralogy of Fallot in adults are very complicated due to longterm right ventricle outlet stricture and chronic hypoxia. Preoperative evaluations and postoperative treatment of complications are necessary. The systemicpulmonary arterial shunts should be performed when hypotrophy of the pulmonary arteries or left ventricles exists. Repair of tetralogy of Fallot in adults has acceptable morbidity and mortality rates with goodlongterm outcomes.
ObjectiveTo evaluate the long-term effectiveness of patients received surgical treatment under the guidance of “West China Classification” of desmoid-type fibromatosis (DTF) in the shoulder girdle.MethodsThe clinical data of 32 patients with DTF in the shoulder girdle admitted between June 2003 and December 2016 were retrospectively analyzed, including 14 males and 18 females, aged 14-56 years with an average age of 36.8 years. The maximum diameter of the tumor was 7-19 cm, with an average of 11.1 cm. According to the “West China Classification” of DTF in the shoulder girdle, there were 4 cases of region Ⅰ, 3 cases of region Ⅱ, 6 cases of region Ⅲ, 3 cases of region Ⅳ, 5 cases of regions Ⅰ+Ⅱ, 5 cases of regions Ⅱ+Ⅲ, and 6 cases of regions Ⅰ+Ⅱ+Ⅲ. In addition, the involvement of blood vessels and nerves was also taken into consideration for choosing a surgical approach. Finally, 12 cases were operated via anteroposterior approach (group A), 14 via posterior approach (group B), and 6 via combined anterior-posterior approach (group C). The 1993 Musculoskeletal Tumor Society (MSTS93) score (including pain, limb function, satisfaction, hand position, hand flexibility, and lifting ability), Japanese Orthopedic Association (JOA) score, range of motion (ROM) of shoulder joint (including flexion, extension, abduction, and adduction), and complications of patients in the 3 groups were recorded and compared.ResultsAll the 32 patients were followed up 30-190 months, with an average of 94.6 months. At last follow-up, complications occurred in 5 cases (15.6%), including 2 cases (16.6%) in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. There was no significant difference in the incidence of complications among the 3 groups (P=1.000). Tumor recurrence occurred in 5 (15.6%) cases, including 1 (8.3%) case in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. No significant difference was found in the recurrence rate among the 3 groups (P=1.000). At last follow-up, MSTS93 score of pain, limb function, satisfaction, hand flexibility, and hand position in groups A and B were significantly better than those in group C (P<0.05), even though no significant difference existed between group A and group B (P>0.05). The lifting ability score in group C was significantly lower than in group A (P<0.05), and no significant difference was found between other groups (P>0.05). The JOA score and flexion, extension, abduction, and adduction activities of shoulder in groups A and B were significantly better than those in group C (P<0.05). The extension activity in group A was significantly better than that in group B (P<0.05), the flexion activity in group B was significantly better than that in group A (P<0.05). There was no significant difference in other indexes between groups A and B (P>0.05).ConclusionTaking a rational approach to fully expose and completely remove the tumor is the key point of surgical treatment for patients with DTF in the shoulder girdle. At the same time, preservation of vital structures and reconstruction of soft tissues should also be taken into consideration. Overall, surgical treatment under the guidance of “West China Classification” of DTF in the shoulder girdle has achieved satisfactory long-term effectiveness.
Objective To investigate the medium- and long-term effectiveness of hip revision with SL-PLUS MIA stem in patients with Paprosky typeⅠ-Ⅲ femoral bone defect. MethodsBetween June 2012 and December 2018, 44 patients with Paprosky typeⅠ-Ⅲ femoral bone defect received hip revision using SL-PLUS MIA stem. There were 28 males and 16 females, with an average age of 57.7 years (range, 31-76 years). Indications for revision comprised aseptic loosening (27 cases) and periprosthetic joint infection (17 cases). The Harris hip scores were 54 (48, 60) and 43 (37, 52) in patients with aseptic loosening and periprosthetic joint infection, respectively. The preoperative femoral bone defects were identified as Paprosky type Ⅰ in 32 cases, type Ⅱ in 9 cases, type ⅢA in 2 cases, and type ⅢB in 1 case. Operation time and intraoperative blood transfusion volume were recorded. During follow-up after operation, the hip joint function were evaluated by Harris hip score and X-ray films, the femoral stem survival was analyzed, and the surgical related complications were recorded. Results The operation time of infected patients was 95-215 minutes, with an average of 125.0 minutes. The intraoperative blood transfusion volume was 400-1 800 mL, with an average of 790.0 mL. The operation time of patients with aseptic loosening was 70-200 minutes, with an average of 121.0 minutes. The intraoperative blood transfusion volume was 400-1 400 mL, with an average of 721.7 mL. All patients were followed up 5.3-10.0 years (mean, 7.4 years). At last follow-up, the Harris hip scores were 88 (85, 90) and 85 (80, 88) in patients with aseptic loosening and periprosthetic joint infection, respectively, both of which were significantly higher than those before operation (P<0.05). Radiological examination results showed that the distal end of the newly implanted femoral stem did not cross the distal end of the original prosthesis in 25 cases, and all femoral stems obtained bone fixation. Two cases experienced femoral stem subsidence and 1 case had a translucent line on the lateral side of the proximal femoral stem. When aseptic loosening was defined as the end event, the 10-year survival rate of the SL-PLUS MIA stem was 100%. When treatment failure due to any reason was defined as the end event, the survival time of the prosthesis was (111.70±3.66) months, and the 7-year survival rate was 95.5%. The 7-year survival rates were 94.1% and 96.3% in patients with aseptic loosening and periprosthetic joint infection, respectively. The incidence of postoperative complications was 9.1% (4/44), among which the prosthesis related complications were 4.5% (2/44), 1 case of dislocation and 1 case of infection recurrence. ConclusionHip revision with SL-PLUS MIA stem has the advantages of simple operation and few postoperative complications in the patients with Paprosky type Ⅰ-Ⅲ femoral bone defect, and the medium- and long-term effectiveness is reliable.
Objective To evaluate the long-term effectiveness of treating early-middle stage avascular necrosis of the femoral head (ANFH) with core decompression and bone grafting. Methods Between January 2000 and December 2006, 87 ANFH patients (114 hips) were treated with core decompression and bone grafting, including 54 cases (62.1%) of alcohol-induced ANFH, 26 cases (29.9%) of steroid-induced ANFH, and 7 cases (8.0%) of idiopathic ANFH. There were 74 males (97 hips) and 13 females (17 hips), aged 20-56 years (mean, 38 years). The disease duration was 3-46 months (mean, 18 months). According to Ficat staging, 16 hips were at stage I, 68 hips at stage II, and 30 hips at stage III. The Harris score and Ficat stage were compared between pre- and post-operation to assess the outcomes clinically and radiologically. The hip survival was analyzed by the Kaplan-Meier method. Results Eighty-seven patients were followed up 5 years to 11 years and 10 months (mean, 8 years and 9 months). The Harris hip score was significantly increased from 73.13 ± 7.17 at preoperation to 81.59 ± 13.23 at postoperation (t= — 9.318, P=0.000). The clinical success rate was 69.3% (79/114) and the radiological success rate was 54.4% (62/114). Kaplan-Meier survival analysis showed that the overall survival rate was 84.2% (96/114); the survival rates of Ficat stage I [100% (16/16)] and stage II [91.2% (62/68)] were higher than that of stage III [60.0%(18/30)] (P lt; 0.01); there was no significant difference between Ficat stage I and II (χ2=1.520, P=0.218). Conclusion Core decompression with bone grafting is a safe and effective procedure for the treatment of Ficat stages I-II (early stage) ANFH, and the long-term effectiveness is satisfactory. But the long-term effectiveness is unsatisfactory for the patients at the Ficat stage III (middle stage).
ObjectiveTo investigate the long-term efficacy and the influencing factors of thymectomy for thymoma patients associated with myasthenia gravis. MethodsWe retrospectively analyzed the clinical and follow-up data of 126 thymoma patients associated with myasthenia gravis underwent extended thymectomy from June 2002 to December 2015 in our hospital. There were 26 males and 37 females at the mean age of 54.51±12.62 years. We built up survival analysis model to analyze the effect of those following factors on postoperative result:sex, the age when operated, the preoperative course of disease, the condition of associating with other diseases, history of critical illness, steroid administration time before operation, Osserman classification, Masaoka staging, WHO pathological type, surgical approach, tumor size and so on. Result The average follow-up time was 35(5-96) months. During follow-up period, 12 patients (19%) achieved complete remission, 39 patients (62%) achieved partial remission, 7 patients (11%) kept stable, 5 patients (8%) deteriorated and the total effective rate was 81%. The result of log-rank analysis showed that the preoperative course of disease (P=0.027), history of critical illness on myasthenia gravis (P=0.035) and Osserman classification (P=0.018) were related to incomplete remission, whlie the result of Cox regression analysis showed that the preoperative course of disease (P=0.001) and Osserman classification (P=0.012) were the independent risk factors for incomplete remission. ConclusionExtended thymectomy is an effective treatment for thymoma patients associated with myasthenia gravis, but the symptom of those patients whose preoperative course of disease are more than 12 months or Osserman classification is at ⅡB, Ⅲ and Ⅳ type of Osserman classification have poor effect after operation.
ObjectiveTo analyze the surgical efficacy and influencing factors of myasthenia gravis (MG) patients with thymic atrophy after thymectomy. MethodsThe clinical data of MG patients with thymic atrophy undergoing thymectomy between October 2014 and May 2018 in Daping Hospital of Army Medical University and Shijiazhuang People Hospital were retrospectively analyzed. ResultsA total of 71 patients were collected, including 40 males and 31 females with a mean age of 45.17±12.42 years. All patients received the surgery successfully. After the surgery, 20 (28.17%) patients were stable remission, 12 (16.90%) patients were minimal manifestation status,19 (26.76%) patients were improved, 5 (7.04%) patients showed no change, 3 (4.23%) patients were worsened, 10 (14.08%) patients were exacerbated and 2 (2.82%) patients were dead. Multivariate logistic regression analysis showed that the preoperative illness duration (OR=4.61, 95%CI 1.13-18.85, P=0.03), and postoperative pyridostigmine combined with immunosuppressive (OR=0.12, 95%CI 0.03-0.45, P=0.00) were independent risk factors for long-term efficacy of thymectomy for MG patients with thymic atrophy. ConclusionEarly surgery after diagnosis of MG and postoperative pyridostigmine combined with immunosuppressive treatment is beneficial to the prognosis of MG patients with thymic atrophy.
Objective To retrospectively analyze the long-term effectiveness of percutaneous laser disc decompression (PLDD) in treatment of cervical spondylosis. Methods Between March 2003 and June 2005, 156 patients with cervical spondylosis were treated with PLDD. There were 74 males and 82 females with an average age of 55.4 years (range, 31-74 years). The disease duration varied from 2 months to 15 years. Fifty-nine patients were classified as cervical spondyloticradiculopathy, 48 as vertebral-artery-type cervical spondylosis, 19 as cervical spondylotic myelopathy, and 30 as mixed type spondylosis. The lesions were located at the levels of C3,4 in 32 discs, C4,5 in 66 discs, C5,6 in 89 discs, and C6,7 in 69 discs, and including 71 one-leve lesion and 85 multi-level lesions. All cases were followed up to study the long-term effectiveness and correlative factors. Results A total of 117 (75%) patients’ symptoms were l ightened or eased up immediately after operation. Discitis occurred in 1 case at 3 days after operation and was cured after 3 weeks of antibiotic use. All patients were followed up 5 years to 7 years and 3 months (5 years and 6 months on average). According to Macnab criteria, the long-term effectiveness was excellent in 60 cases (38.46%), good in 65 cases (41.67%), fair in 19 cases (12.18%), and poor in 12 cases (7.69%); the excellent and good rate was 80.13%. No significant difference was observed in the wedge angels and displacements of the intervertebral discs between before and after operations (P gt; 0.05). Multiple-factors logistic regression showed that the disease duration and patient’s age had obvious relationship with the effectiveness of treatment (P lt; 0.05), while the type of cervical spondylosis, disc protrusion degree, mild cervical instabil ity, and lesion scope had no correlation with the effectiveness of treatment (P gt; 0.05). Conclusion PLDD is safe and effective in treatment of cervical spondylosis with less compl ication. There is no impact on the stabil ity in cervical spinal constructs. The disease duration and patient’s age have obvious impact on the long-term effectiveness of treatment. The type of cervical spondylosis, disc protrusion degree, cervical instabil ity, and lesion scope are not the correlative factors.
ObjectiveTo evaluate the influence of the shell angle of cervical artificial disc on long-term effectiveness of cervical artificial disc replacement (CADR).MethodsThe clinical data of 71 patients who were treated with single-level CADR with Bryan prosthesis between December 2003 and December 2007 and followed up more than 10 years, were retrospectively analyzed. There were 44 males and 27 females with an age of 26-69 years (mean, 45.9 years). According to the shell angle of the cervical artificial disc which was measured on the postoperative lateral X-ray film, the patients were divided into kyphotic group (shell angle was negative) and non-kyphotic group. The following evaluation indexes before operation and at last follow-up were compared between 2 groups. Radiographic indexes included the range of motion (ROM) of cervical spine, the ROM of operated level, Cobb angle of operated level (the negative value indicated that the segmental kyphosis occurred at operated level), paravertebral ossification (PO) grades (grades 3 and 4 were high grade PO). Clinical indexes included Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), and overall effectiveness evaluation (Odom criteria).ResultsThere were 24 patients in kyphotic group and 47 patients in non-kyphotic group. There was no significant difference in baseline data including gender, age, and operated level between 2 groups (P>0.05). All the patients in 2 groups were followed up 121-165 months (mean, 128 months). There was no significant difference in preoperative ROM of cervical spine and ROM of operated level between 2 groups (P>0.05); but the preoperative Cobb angle of operated level in kyphosis group was significantly lower than that in non-kyphotic group (t=2.636, P=0.013). There was no significant difference in ROM of cervical spine at last follow-up between 2 groups (t=1.393, P=0.168), however, the ROM and the Cobb angle of operated level in kyphotic group were significantly lower than those in non-kyphotic group (P<0.05). According to the Cobb angle of operated level at last follow-up, there were 9 patients (37.5%) with segmental kyphosis in kyphotic group and 7 patients (14.9%) in non-kyphotic group, showing significant difference (χ2=4.651, P=0.031). There was a significant difference in PO grades between 2 groups (Z=2.894, P=0.004) at last follow-up. In kyphotic group, there were 10 patients (41.7%) with low grade PO and 14 patients (58.3%) with high grade PO; and in non-kyphosis group, there were 36 patients (76.6%) with low grade PO and 11 patients (23.4%) with high grade PO. There was no significant difference in JOA scores and NDI before operation and at last follow-up, and the JOA improvement rate, NDI decline, and Odom criteria score at last follow-up between 2 groups (P>0.05).ConclusionThe shell angle of cervical artificial disc may lead to a decrease in the postoperative segmental ROM, and an increased occurrence of segmental kyphosis and high incidence of PO.
