ObjectiveTo evaluate the value of clinical application of determination of lower venous pressure in the diagnosis and treatment of deep venous thrombosis (DVT). MethodsThe 90 patients with DVT of unilateral lower limb who were admitted by using color Doppler or deep veins of lower limb angiography in our hospital during the period of 2013 July to 2014 June were selected and as the research object (case group), 37 cases were male, 53 cases were female; the age was 18-84 years old, mean age was 59.48 years old. According to the development of disease, 90 cases were divided into acute 30 cases, subacute 30 cases, and chronic 30 cases; and according to the pathological types were divided into the central type in 30 cases, 30 cases of peripheral type, and 30 cases of mixed type. At the same time the without lower extremity DVT volunteers of 20 cases were selected as normal control group, including male 9 cases, female 11 cases; age was 21-65 years old, average age was 38.7 years old. The static venous pressure (P0), dynamic venous pressure (P00), and decreased pressure ratio (Pd) of double lower limbs of participants in 2 groups were determinated and comparative analyzed. ResultsThe P0 and P00 of patients with different development of disease and pathological types of the case group were higher than those of the normal control group (P < 0.01), and the Pd was lower than that of the normal control group (P < 0.01). In case group, the P0 and P00 of acute phase were higher than those of the normal control group (P < 0.01), the P0 of central type was higher than that of the peripheral type and mixed type (P < 0.01), and the Pd central type was lower than that of mixed type (P < 0.01). The above 3 indexes' differences of double lower limbs in the normal control group had no statistical significance (P > 0.01). In case group, the P0 and P00 of ipsilateral limb in different development of disease and pathological types were higher than those of the healthy limb, and the Pd were lower than that of the healthy limb (P < 0.01). ConclusionsLower extremity venous pressure measurements can be used in clinical detection for early lower limb DVT, and can be used as the objective index of clinical evaluation curative effect for the treatment of DVT. It is a simple and practical clinical detection method.
Objective To explore the value of color Doppler ultrasonography and plasma D-dimer in diagnosis of lower limb deep venous thrombosis (DVT).Methods The clinical data of 70 cases of patients with lower limb DVT diagnosed clinically were retrospectively studied. The lower limb venous of each patient was examined by color Doppler ultrasonography and the plasma level of D-dimer were measured, furthermore the plasma levels of D-dimer in different phase and different type of thrombosis were compared. Results The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of plasma D-dimer and ultrasonography examination in lower limb DVT were 100%, 66.7%, 97.0%, 100%, and 97.1%, and 98.4%, 83.3%, 98.4%, 83.3%, and 97.1%, respectively. The plasma D-dimer in acute phase 〔(6 451±4 012.22) μg/L〕 and subacute phase 〔(2 063±1831.35) μg/L〕 of lower limb venous thrombosis were significantly higher than that in normal control group 〔(310±66.70) μg/L〕, Plt;0.01 and Plt;0.05, which was not different from that in chronic phase 〔(466±350.52) μg/L〕. Meanwhile, the plasma D-dimer in mixed limb venous thrombosis group 〔(4 464±3 753.16) μg/L〕 and central limb venous thrombosis group 〔(2 149±1 911.53) μg/L〕 were significantly higher than that in control group (Plt;0.05 and Plt;0.01), which was not different from that in peripheral limb venous thrombosis group 〔(560±315.62) μg/L〕. Conclusion Color Doppler ultrasonography is an optimal method and the plasma D-dimer is a predictive index in diagnosis of lower limb DVT.
【Abstract】ObjectiveTo review the epidemiology, etiology, pathology, clinical presentation, diagnosis and treatment, recurrance and prognosis of Mondor disease. MethodsLiteratures on Mondor disease were reviewed, and our study of Mondor disease was also included. ResultsMondor disease is difficult to diagnose, but is with good prognosis in most patients. It’s unclear whether Mondor disease is associated with the etiology of breast cancer. ConclusionThe diagnosis and therapy of Mondor disease are important, especially when it is accompanied with breast cancer.
Objective To investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital to enrich the epidemiological data of chronic thromboembolic pulmonary hypertension (CTEPH) in China.Methods We conducted a retrospective study to investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital from 2008 to 2012. Results The incidence of CTEPH was 5.24% . About 62.90% of venous thromboembolism/pulmonary embolism (VTE/PE) patients were unprovoked, and about 53.85% of CTEPH patients was unprovoked. About 38% of CTEPH patients had no history of VTE, and 62% of CTEPH patients had no history of acute pulmonary embolism. None of the CTEPH patients was treated by pulmonary thromboendarterctom (PTE) , and about 53.85% of patients were only given anticoagulant monotherapy. Conclusions The incidence of CTEPH is higher in our hospital than reported. This phenomenon may be related to the lack of awareness of risk factors of CTEPH and the insufficient thrombolytic and anticoagulant therapy to acute pulmonary embolism. It’s very urgent to standardize the diagnosis and management of CTEPH in pulmonologists.
ObjectiveTo investigate the significance of catheter thrombolysis combined with one-stage iliac vein percutaneous transluminal angioplasty (or stent implantation) in the treatment of acute left lower extremity deep venous thrombosis secondary to Cockett syndrome.MethodsForty-one cases of Cockett syndrome complicated with acute left lower extremity deep vein thrombosis were retrospectively analyzed and summarized in our hospital from January 2016 to June 2019. Catheter directed thrombolysis was performed under the protection of filter, and percutaneous transluminal angioplasty or stent implantation was performed in the first stage of the iliac vein stenosis or occlusion after thrombolysis. Compared the circumference of upper and lower legs of 15 cm above and below patella of the healthy and affected limbs, before and after treatment, and analyzed the venous patency rate.ResultsThe average time of using thrombolytic catheter were (7±3) days, and the average dosage of urokinase was (358.32±69.38) ×104 U. A total of thirty-five Bard stents were implanted (35 cases), four cases underwent percutaneous transluminal angioplasty, and two cases gave up treatment. Before and after treatment, the circumference difference of the higher leg, the circumference difference of the lower leg, and the venous patency were significantly different before and after thrombolysis (P<0.01). The venous patency rate was 58%–75% in this group, and the average venous patency rate was (61±10)%. There was no severe bleeding complication occurred. Thirty-five patients were followed up for 3–26 months, the preservation rate of the valve was 82.86% (29/35), and the first patency rate of iliac vein was 100% (39/39). During the follow-up period, thrombosis recurred in one case of untreated iliac vein, and acute thrombosis in the right side of one case was caused by long iliac vein stent entering the inferior vena cava. No pulmonary embolism was found.ConclusionOn the basis of catheter thrombolysis, one stage removal of iliac vein obstruction in the treatment of acute left lower extremity deep venous thrombosis can relieve the clinical symptoms, reduce the recurrence rate of thrombosis, and reduce the occurrence of deep vein thrombosis syndrome after catheter thrombolysis.
ObjectiveTo investigate the risk factors of postoperative portal vein thrombosis (PVT) after devascu-larization in patients with cirrhotic portal hypertension. MethodsThe clinical data of 40 patients with cirrhotic portal hypertension treated with splenectomy and gastric pericardial devascularization were retrospectively analyzed to investigate the related risk factors. ResultsA total of 12 of the 40 patients suffered from PVT (30.00%). The results of multivariate analysis showed that portal vein diameter, postoperative portal vein velocity, platelet count at 2 weeks postoperatively, and postoperative portal vein pressure were the factors influencing the incidence of PVT after devascularization. Patients with the greater portal vein diameter and platelet count at 2 weeks postoperatively, the lower postoperative portal vein velocity and postoperative portal vein pressure, had higher ratio of PVT (P < 0.05). ConclusionPortal vein diameter, portal vein blood flow velocity, platelet count, and postoperative portal vein pressure were the main risk factors for PVT after surgery in patients with cirrhotic portal hypertension.
Objective To analyze inducing factors and clinical characteristics of deep venous thrombosis (DVT) and to explore clinical value of soluble cell surface differentiation antigen 40 ligand (sCD40L) in early diagnosis of DVT. Methods The patients with the DVT of lower extremity who had not received the anticoagulant and thrombolytic therapy in the Nanchong Central Hospital from January 2012 to January 2017 were collected, these patients were divided into an early-acute stage, mid-acute stage, late-acute stage, and subacute stage according to the clinical course of DVT. The sCD40L expression in the peripheral blood of DVT patients were detected by the enzyme linked immunosorbent assay. Results There were 100 patients with the DVT were included, including 31 cases of early-acute stage, 26 cases of mid-acute stage, 21 cases of late-acute stage, and 22 cases of subacute stage; 66 patients with the peripheral type, 28 patients with the central type, and 6 patients with the mixed type. ① The fracture, malignant tumor, long time in the bed following the thoracic or abdominal operation, joint replacement, and caesarean section were the successively main risk factors of the DVT. ② The early-acute stage of DVT was more common in the fracture patients, the mid- and late-acute stage of DVT often occurred in the joint replacement sufferer, and the subacute stage of DVT was usually found in the malignant tumor patients. ③ The sCD40L expression in the patients with the different stage DVT was signifiantly higher than that in the control group (20 healthy people in the physical examination, P<0.05). Furthermore, there was a significant difference in the different stage DVT patients (F=26.57, P=0.02), that is, the expression of sCD40L was the highest in the early-acute stage of DVT, and then gradually reduced (P<0.05). ④ The sCD40L expression had a significant difference among the central type DVT, mixed type DVT, and peripheral type DVT (F=12.51, P=0.02), which in the peripheral type DVT was significantly higher than that of the central type DVT (P<0.05) and mixed type DVT (P<0.05), but had no difference between the central type DVT and the mixed type DVT (P>0.05). ConclusionsCD40L might act as a blood index of early diagnosis and judgement of extent of DVT, especially be helpful in early-acute stage of DVT.
