ObjectiveTo investigate the effect of in vitro fenestration on reconstruction of left subclavian artery in endovascular treatment of aortic dissection.MethodsA total of 89 patients with aortic dissection involving left subclavian artery were treated by endovascular treatment in the Second Affiliated Hospital of Fujian Medical University from February 2017 to January 2020. There were 44 patients in the test group, including 36 males and 8 females, with an average age of 58.02±13.58 years. There were 45 patients in the control group, including 35 males and 10 females, with an average age of 54.10±12.32 years. The left subclavian artery was reconstructed by in vitro fenestration in the test group and by chimney technique in the control group. The clinical data were compared between the two groups.ResultsThe operation time of the test group was longer than that of the control group (126.16±7.53 min vs. 96.49±6.52 min, P<0.01). The median follow-up time was 31 (13-48) months. The incidence of endoleak in the test group (4.7%) was lower than that in the control group (18.6%, P=0.04) during the follow-up. There was no statistical difference in the incidence of stroke, myocardial infarction, false lumen thrombosis, retrograde aortic dissection or left subclavian artery occlusion between the two groups (P>0.05).Conclusion In vitro fenestration for reconstructing left subclavian artery in thoracic endovascular aortic repair of aortic dissection is safe and feasible, which is worthy of further clinical promotion.
ObjectiveTo investigate the clinical effect of in situ fenestration combined with chimney technique in the treatment of aortic dissection involving left common carotid artery.MethodsFrom January 2012 to June 2019, 53 patients with aortic dissection involving left common carotid artery were selected. There were 21 patients in the test group, including 14 males and 7 females, with an average age of 57.2±11.2 years; there were 32 patients in the control group, including 20 males and 12 females, with an average age of 56.7±12.1 years.

ObjectiveTo explore the clinical efficacy of percutaneous endoscopic interlaminar discectomy (PEID) and interlaminar fenestration discectomy in the treatment of lumbar (L) 5-Sacral (S) 1 lumbar disc herniation (LDH).MethodsLDH patients were retrospectively included from January 2016 to Januray 2018. And the patients were divided into the PEID group and the fenestration group according to their choice of different surgical methods. The operation time, intra-operative blood loss, and bed rest time in the two groups were recorded. The preoperative and postoperative [1 week, 1 month, 3 months, and last follow-up (>12 months)] Visual Analogue Score (VAS) of the lumbago and leg pain between the two groups were compared; the preoperative and postoperative [1 week, and last follow-up (>12 months)] Oswestry Disability Index (ODI) and also the postoperative [(>12 months)] therapeutic effect (modified MacNab) between the two groups were compared.ResultsA total of 66 patients were included, with 31 in the PEID group and 35 in the fenestration group. There was no significant difference in age, gender and course of disease between the two groups (P>0.05). There were leakage of cerebrospinal fluid and transient lumbago, leg pain and numbness, which were worse than those before operation in the PEID group (1 and 1 patient, respectively) and the fenestration group (2 and 3 patients, respectively). There were statistically significant differences between the PEID group and the fenestration group, in the operative time [(90.65±9.98) vs. (66.23±16.50) minutes], intra-operative blood loss [(51.77±18.64) vs. (184.29±78.38) mL], and bed time [(2.87±0.92) vs. (7.49±1.20) d] (t=−7.365, t’=−9.697, t=−17.374, P<0.001). There was no significant difference in the preoperative VAS score (lumbar-leg pain) and ODI index, and the ODI index at each postoperative time point, between the two groups (P>0.05). VAS score (lumbago) and VAS score (leg pain) in the PEID group at each postoperative time point were lower than those in the fenestration group (P<0.05); VAS scores (leg pain) at other time points were not statistically significant between the two groups (P > 0.05). VAS (lumbar-leg pain) score and ODI index at each postoperative time point were lower than those before the surgery. The was no statistically significant difference in the PEID group (90.32%) and fenestration group (85.71%) in the excellent rate (χ2=0.328, P=0.713).ConclusionsPEID has less surgical trauma, less bleeding, short bed rest, fast recovery, and better relief of postoperative lumbago symptoms. It is worthy of further promotion in clinical work.
Objective To observe and evaluate the clinical effect of the new fenestration rammer in the treatment of thoracolumbar burst fracture by posterior internal fixation and reduction of lamina with finite fenestration decompression. Methods Patients with thoracolumbar burst fractures admitted to Zigong Fourth People’s Hospital between September 2017 and January 2020 were retrospectively selected. The patients were divided into observation group and control group according to different surgical methods. The observation group used a new tamping device with finite fenestration rammer of unilateral lamina to reduce the spinal occupying bone mass, and the control group used conventional instruments for reduction of intraspinal fracture masses. The operation time, intraoperative blood loss, CT measurement of sagittal diameter ratio of spinal canal and the number of cases of postoperative vertebral empty shell phenomenon were recorded in the two groups, and Frankel grading evaluation of spinal nerve function was conducted. Results A total of 67 patients were included. There were 33 cases in the observation group and 34 cases in the control group. The patients in both groups were followed up for 12 to 16 months, with an average of (14.45±2.25) months. The improvement rate of Frankel rating in each group was 100%. In the control group and the observation group, except for the sagittal diameter ratio of spinal canal before operation (P=0.616), the operation time [(150.44±26.47) vs. (120.91±20.86) min], the intraoperative blood loss [(244.41±42.97) vs. (183.33±34.56) mL], the sagittal diameter ratio of spinal canal one week after operation [(92.50±2.32)% vs. (93.72±2.40)%], the sagittal diameter ratio of spinal canal at the last follow-up [(91.50±2.96)% vs. (93.17±3.27)%] and the occurrence of empty shell phenomenon (13 vs. 5 cases) were statistically significant (P<0.05). The intragroup comparison showed that the sagittal diameter ratio of spinal canal was improved one week after operation and at the last follow-up compared with that before operation (P<0.05), there was no significant difference in the sagittal diameter ratio of spinal canal between one week after operation and the last follow-up (P>0.05). Conclusions The new fenestration rammer can effectively reduce the spinal occupying bone mass in thoracolumbar burst fracture, effectively restore the volume of the spinal canal, achieve the purpose of decompression, effectively prevent the formation of vertebral shell, maximize the retention of the stable structure of the posterior column, and avoid iatrogenic nerve injury. It is safe and effective.
ObjectiveTo evaluate the feasibility, safety and efficacy of endovascular treatment for chronic thoracoabdominal aortic dissection. MethodsThe patients with chronic thoracoabdominal aortic dissection who underwent total endovascular treatment at Shanghai City First People’s Hospital between December 2021 and March 2024 were retrospectively analyzed. The patients were divided into single-trunk group and double-trunk group according to the treatment methods. Clinical data including demographic characteristics, preoperative risk factors, surgical details, postoperative complications and long-term follow-up data were collected. Outcome measures mainly included surgical success rate, in-hospital mortality, endoleak rate and incidence of branch restenosis. ResultsThirty-four patients with thoracoabdominal aortic dissection were treat with total endovascular treatment. That success rate of operation was 100%. The in-hospital mortality was 2.94%. the incidence of paraplegia was 0.00%. the incidence of cerebral infarction was 2.94%. The incidence of type Ⅲ endoleak was 5.88%. The incidence of branch artery stenosis was 8.82%. The incidence of dissection progression was 8.82%. The reintervention rate was 14.71%. In the aspect of reconstruction of splanchnic artery branches, fenestration stent was the main method in the single-trunk group, and branch stent was the main method in the double-trunk group, the difference was statistically significant (P<0.05). There was no significant difference in perioperative and mid-term follow-up results between the two groups (P>0.05). ConclusionTotal endovascular treatment is a safe and effective treatment option for patients with thoracoabdominal aortic dissection.
ObjectiveTo evaluate the long-term effects of fenestration on patients at different risk levels, who performed external conduit total cavo-pulmonary connection operation.MethodsThis was a retrospective analysis which enrolled 383 patients undergoing external conduit total cavo-pulmonary connection in Fuwai Hospital from 2008 to 2015. Based on the preoperative data and whether fenestration in the operation, the whole cohorts were divided into four subgroups: a high risk group with fenestration(mean age: 10.53±7.06 years, 55 males), a high risk group with non-fenestration(mean age: 9.30±7.83 years, 43 males), a low risk group with fenestration(mean age: 8.91±7.13 years, 65 males) and a low risk group with non-fenestration(mean age: 8.23±5.34 years, 67 males). Then we collected and analyzed the perioperative data and long-term prognosis of this cohorts in different risk levels.ResultIn the high-risk group, the duration of chest drainage in fenestration group was significantly shorter than that of the non-fenestration group (12.39±12.03 d vs. 23.30±15.36 d, P=0.001). The incidence of delayed chest drainage in the fenestration group was lower than that in the non-fenestration group (25.0% vs. 47.1%, P=0.002). In addition, the length of hospital stay was shorter than that of the non-fenestration group (18.91±12.79 d vs. 29.68±37.77 d, P=0.004), with significant statistical difference. In the low risk group, there were 3 (2.7%) and 2 (1.6%) deaths at the follow-up in the non-fenestration and fenestration groups respectively (P=0.761). And 1 patient (1.3%), 1 patient (1.4%) died in the fenestration and non-fenestration group (P=0.593) in high risk group. However, there was no statistically significant difference among the fenestration and non-fenestration groups in terms of long-term intestinal protein loss syndrome and arrhythmia in different risk level groups.ConclusionFenestration can reduce the incidence of early complications and hospital stay, effectively, especially for the high-risk patient. Fenestration is recommended for high-risk patients with external conduit total cavo-pulmonary connection operation.
