ObjectiveTo evaluate clinical outcomes of thoracic endovascular aortic repair (TEVAR)for the treatment of Stanford type B aortic dissection (AD)and descending aortic aneurysm. MethodsClinical data of 20 patients with Stanford type B AD or descending aortic aneurysm who underwent TEVAR in West China Hospital from March to June 2013 were retrospectively analyzed. There were 19 male and 1 female patients with their age of 41-76 (58.3±10.2)years. Clinical outcomes were analyzed. ResultsAmong the 20 patients, 18 patients were successfully discharged, 1 patient refused further postoperative treatment and was discharged, and 1 patient died postoperatively. Sixteen patients (88.9%)were followed up for over 3 months. In all the patients during follow-up, true lumen diameter recovered within the scope of intravascular stents, and there was thrombosis in false lumen or aneurysm lumen. ConclusionTEVAR provides a new choice with significant advantages for the treatment of Stanford type B AD, especially for the elderly and patients with concomitant serious diseases, so it is worthy of clinical application.
Objective To summarize the experience of surgical treatment for 84 patients with aortic dissection, investigate the surgical technique and perioperative treatment, and to improve surgical results. Methods The operations were performed in 50 patients with aortic dissection of Stanford A， Bentall or Cabrol operations were performed in 24 patients, graft replacement of ascending aorta in 8 patients, Trusler operation in 5 patients, Wheat operation in 5patients, operation of ascending aorta and aortic arch in 8 patients.Stentgraft were used in 34 patients with aortic dissection of Stanford B. Results There were 11 hospital death,the hospital mortality was 13.1%.There were 3 operative deaths.One patient with ascending aortic and hemiarch grafting died of aortic root bleeding;one patient with replacement of ascending aorta died of failure to restart heart beating；one patient with ascending aortic and hemiarch grafting died of rapture of aortic dissection. There were 8 postoperative deaths, including low cardiac output syndrome in 2 patients, lung infection in 2 patients, renal failure in 2 patients， respiratory failure in 1 patient and permanent mental anomaly in 1 patient. The complications were occurred in 16 patients. The followup period was 3 months to 10 years, and carried out in 62 patients（84.9%，62/73).One died of endocarditis, another one died of sudden death. Conclusion The surgicaltreatment of aortic dissection could be carried out safely based on the accurate diagnosis， specific surgical strategy and fine surgical technique.
目的:探讨带膜支架腔内隔绝术治疗B型主动脉夹层的技术方法及疗效。方法:对近年我院收治的40例主动脉夹层进行分析。40例患者均行股动脉穿刺插管至升主动脉造影，了解主动脉真假腔、夹层裂口及其与重要血管分支位置关系。切开右或左侧股动脉置入覆膜血管内支架，封堵原发破口，置入支架后重复造影检查。观察真假腔血流变化、主动脉分支供血的情况。结果:40例患者支架置入定位准确，术后即刻造影显示真腔血流恢复正常。手术成功率100%，无术中转开胸手术，无截瘫及瘤体破裂等严重并发症，无围手术期死亡。所有患者术后3～6个月复查增强CT，假腔不再显影，支架通畅，无扭曲、移位。结论:带膜支架腔内隔绝术治疗B型主动脉夹层具有创伤小，术后恢复快，手术死亡率低，手术成功率高的优点，但远期效果有待进一步观察。
摘要:目的:探讨改良De Vega环缩术与经典De Vega环缩术相比对于治疗重度三尖瓣返流是否具有更好的成形效果。方法: 2007年12月至2009年3月对29例重度三尖瓣返流的患者行De Vega环缩术。其中16例行改良De Vega环缩术,13例行经典De Vega环缩术,随访比较两组患者三尖瓣返流程度,右心室舒张期末内径,EF值及心功能分级。以秩和检验分析研究两组患者三尖瓣返流程度和心功能分级的差异,以t检验研究两组患者右心室舒张末期内径及EF值变化。结果:术前两组患者一般指标无显著差异。两组患者随访时间无显著差异。随访经典De Vega组重度返流1例,中度返流5例,轻度返流5例,微量及无返流2例;改良De Vega组无中、重度返流,轻度返流8例,微量及无返流8例。经分析显示两组患者三尖瓣返流程度结果差异有统计学意义(Plt;0.05)。经典De Vega组心功能分级I级5例,II级7例,III级1例;改良De Vega组I级7例,II级8例,III级1例,两组患者心功能差异无统计学意义(Pgt;0.05)。两组患者右室舒张期末内径及EF值组内比较随访与术前差异均有统计学意义(Plt;0.05),随访时组间比较差异有统计学意义(Plt;0.05), 改良De Vega环缩术随访时右室舒张期末内径缩小更显著,射血分数改善更明显。结论:改良De Vega环缩术治疗重度三尖瓣返流效果优于经典De Vega环缩术。Abstract: Objective: To compare the efficacy of one kind of modified De Vega technique and traditional De Vega technique for the correction of severe tricuspid regurgitation. Methods: From December 2007 to March 2009, 29 patients were treated with tricuspid valve annuloplasty. These were 16 patients in modified De Vega annuloplasty group and the others (13 patients) in traditional De Vega annuloplasty group. The grade of tricuspid regurgitation、New York Heart Association (NYHA) functional class、ejection fraction (EF) and the right ventricular enddiastolic dimension of two groups were followed and reviewed. Results: There was no statistically difference between two groups about preoperative characteristics and followup time. There was 1 patient with severe TR, 5 patients with moderate TR, 5 patients with mild TR and 2 patients without TR in traditional De Vega annuloplasty group after the operations. In modified De Vega annuloplasty group, no patient was observed with severe or moderate TR, 8 patients with mild TR, and 8 patients without TR. At interval time, there was significant difference in the grade of tricuspid regurgitation between two groups (Plt;0. 05). Both tricuspid valve plasty techniques could reduce the right ventricular enddiastolic dimension and improve ejection fraction significantly (Plt; 0. 05), and there was significant difference in the right ventricular enddiastolic dimension and ejection fraction at interval time between two groups (Plt;0.05). Conclusions: The outcome of modified tricuspid De Vega technique is superior to that of traditional De Vega technique in correcting severe tricuspid regurgitation.
