To report an unusual approach to endovascular exclusion of a large aortic pseudoaneurysm.
A 63-year-old male had an unsuccessful endovascular repair of an aortic anastomotic pseudoaneurysm that left an expanded, uncovered Palmaz stent lying obliquely within the aorta. After nearly 3 years, the pseudoaneurysm enlarged to 7 cm, and the patient became symptomatic. Repair of the pseudoaneurysm was accomplished by crushing the indwelling stent to allow placement of a stent-graft.
Malpositioned stents that are hindering an endoluminal procedure may be crushed against the arterial wall in vivo to facilitate passage of endovascular instruments or devices.
报告一种用于血管腔内排除大型主动脉假性动脉瘤的非常规方法。
一名63岁男性患者接受主动脉吻合口假性动脉瘤的血管腔内修复术未成功，导致一个扩张的、未覆盖的帕尔马兹支架斜置于主动脉内。近3年后，假性动脉瘤增大至7厘米，患者出现症状。通过挤压留置支架以允许植入覆膜支架完成了假性动脉瘤的修复。
阻碍腔内手术的位置不当的支架可在体内压向动脉壁，以利于血管内器械或装置通过。
