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.
Abstract: Percutaneous balloon pulmonary valvuloplasty (PBPV) has become the first choice for the treatment of pulmonary valve stenosis (PS). PBPV is used not only in the independent way to relieve Milo-Ⅰ amp; Ⅱ type of PS as an alteration of surgery, but also in the combination way with surgical treatment to some multiple or complex congenital heart defect,where it plays a part as a pre-operative appeasement or a co-operative procedure, even a supplementary expedience to some failed surgery post-operatively. In this paper, the anatomic classification of PS, the usage of ultrasounic examination, the indication and contraindication, the method and skill during operation, and the effect evaluation of PBPV are reviewed.
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.
