腔内隔绝术治疗Stanford B型夹层动脉瘤

Endovascular graft exclusion in treatment of Stanford B aortic dissection

目的探讨腔内隔绝术EVGE治疗Stanford B型夹层动脉瘤的价值及应用经验。方法采用国产人工覆膜支架治疗Stanford B型夹层动脉瘤9例。经核磁共振(MRI)、主动脉造影明确瘤体和夹层破口位置及大小,标记破口位置。准确选定覆膜支架型移植物,DSA监控下将支架导入瘤腔及裂口位置,完全封闭破口,使真、假腔隔绝。结果破口全部封闭成功,支架没有移位、狭窄等并发症。术后超声和螺旋CT检查假腔内有血栓形成。9例患者均康复出院。结论EVGE是一种治疗Stanford B型夹层动脉瘤的有效方法,早期结果满意,中远期效果还有待进一步观察。

Objective To discuss the value and practical experience of the treatment of Stanford B aortic dissection by endovascular graft exclusion（EVGE）.Methods Nine patients undergoing the procedure of EVGE were studied.The location and size of tumors and dissecting crack point were identified by MRI and aortic angiography,and the dissecting crack was marked.Proper cervical ligament support was chosen and imported into the tumor through the dissecting crack point under DSA monitoring.Then the dissecting point was sealed and the man-made cavity was separated from the genuine one.Results The procedure was technically successful in all patients.No severe complication occurred during the period.Conclusions These preliminary results suggest that EVGE is safe and efficient for Stanford B aortic dissection.Although the long term results are not available,yet early results of EVGE in treatment of Stanford B aortic dissection are satisfactory.
