PURPOSE
We present four cases of dissection of the thoracic descending aorta that underwent treatment with an auto expandable dácron-covered stent.
METHODS
The stent was deployed through the femoral artery in the hemodynamic laboratory after sedation, local anesthesia in both inguinal areas and systemic heparinization. The catheter with the stent was introduced through a cutdown in the left femoral artery until the area in the thoracic aorta with the previously diagnosed tear.
RESULTS
The stent was expanded with immediate occlusion of the false lumen. The whole procedure took 90 minutes and the patients were discharged without complications.
CONCLUSION
Stent utilization is an important step to improve treatment results in type B aortic dissection.
目的
我们报告4例降主动脉夹层患者，他们接受了自膨式涤纶覆膜支架治疗。
方法
在血流动力学实验室，于镇静、双侧腹股沟区局部麻醉及全身肝素化后，通过股动脉植入支架。将带支架的导管经左股动脉切开处插入，直至胸主动脉先前诊断出夹层撕裂的部位。
结果
支架扩张后假腔立即闭塞。整个过程耗时90分钟，患者出院时无并发症。
结论
使用支架是改善B型主动脉夹层治疗效果的重要一步。
