目的探讨覆膜支架血管内隔绝术(EVGE)治疗胸主动脉夹层动脉瘤(TADA)的临床疗效.方法本研究11例Debakey B型TADA患者,经CT增强检查确诊.经股动脉置入覆膜支架,封堵胸主动脉破裂口,置入后造影复查证实疗效,术后随访采用彩超或增强CT检查.结果 11例患者共成功置入13个支架,2例术后支架远端出现内漏,6个月后内漏自行封闭;随访2年,所有患者内膜破裂口封闭,胸降主动脉和腹主动脉真腔扩大,假腔内血栓形成,支架位置、形态正常.结论 EVGE是治疗TADA的安全有效方法.

Objective To investigate the clinical efficacy of endovascular stent-graft placement on thoracic aortic dissection.Methods Eleven patients with Debakey(type Ⅲ) thoracic aortic dissection were diagnosed by contrast enhanced CT.Vascular procedure was performed and stent-grafts was placed via femoral artery to occlude the primary entry tear.Aortography was performed immediately after the procedure and identify the final result of treatment.Colour doppler ultrasonography and CT were used for follow-up.Results The procedures of stent-grafts placements were technically and clinically successful in the 11 patients,totally 13 stents were placed.Distal endo-leak occurred in 2 cases and was automatically sealed 6 months after the treatment procedure.In follow-up of 2 years,closure of the entery tear was identified in all of the patients,and the true lumen of thoracic and abdominal aorta were enlarged,thrombosis in the false lumens were demonstrated.The location and shape of the stent-grafts were normal.Conclusions Debakey typeⅢthoracic aortic dissection can be treated safely and effectively by means of endovascular stent-graft placement.
