摘要
目的 :探讨血管内带膜支架置入术治疗主动脉夹层的疗效。方法 :采用MedtronicTalentTM带膜支架置入治疗 5例StanfordB型亚急性期主动脉夹层患者 ,在全麻、数字减影血管造影术 (DSA)监控下 ,切开股动脉 ,将带膜支架系统置入降主动脉内膜破裂口处 ,封闭破口。结果 :所有患者带膜支架置入后破口完全封闭 ,真腔血流恢复正常 ,技术成功率 10 0 %。无急诊开胸手术、截瘫、瘤体破裂等严重并发症 ,无围手术期死亡。 1例术中发生新的StanfordA型夹层 ,所有患者在 1～ 8[平均 (4 .5 5± 2 .1) ]个月的随访期内经螺旋CT证实无内漏及支架移位等并发症发生。结论 :血管内带膜支架置入术治疗亚急性降主动脉夹层具有技术可靠、安全性高、术后恢复快、手术成功率高等优点 。
Objective:To introduce the preliminary experience of endovascular stent-graft (ESG) placement for patients with type B aortic dissection. Method: Five patients (male 4,female 1) aged 34～50 years with subacute aortic dissection were treated with ESG under digital subtraction arteriography(DSA).Entry tears were located in the descending thoracic aorta in all patients. Result:Stent-grafts were placed successfully in all patients. All ruptures were completely closed and the blood flow returned to normal in the true lumen. There was a new dissection in ascending aorta in one patient. However, there was no death or other serious complications at perioperation and during the subsequent average follow-up period of 4.5 months. No secondary stent-graft procedures were required in all patients. Conclusion: ESG placement of subacute aortic dissection is a safe, reliable and effective method and may be an alternative to surgical graft replacement in selective patients.
