目的:探讨带膜血管内支架置入治疗B型主动脉夹层的效果。方法:B型主动脉夹层5例,切开股动脉置入带膜血管内支架封堵原发破口后重复造影检查。结果:均成功置入支架,置入的人造血管支架使降主动脉和腹主动脉真腔扩大,明显改善降主动脉及分支血管血流。术后4例患者肾功能恢复正常,1例内漏患者术后随诊,7个月后消失,夹层近端假腔内均有血栓形成。结论:带膜血管内支架置入是B型主动脉夹层有效的治疗途径,远期效果还有待进一步观察。
Objective: To investigate the effect of stent implantation on B-type aortic dissection. Methods: Five cases of type B aortic dissection were excised and the femoral artery was incised and placed in a vascular stent. Results: All of them were successfully placed into stents. The stents inserted into them made the eardrums of the descending aorta and abdominal aorta expand and the blood flow of the descending aorta and branch vessels was significantly improved. After operation, the renal function returned to normal in 4 patients. One patient with internal leakage was followed up after operation and disappeared after 7 months. There was thrombosis in the proximal false lumen. Conclusion: The stent graft with vascular stent is an effective treatment for type B aortic dissection. The long-term effect remains to be further observed.
