A self-expanding stent has recently been introduced for the treatment of wide-neck aneurysms. We describe two cases of stent malposition within large aneurysms. In the first case, the stent was dislodged during microcatheterization. This was managed by placement of a second stent through the interstices of the first followed by aneurysm coiling. In the second case, after deployment, the proximal portion of the stent moved into the aneurysm as the exchange guidewire was removed. This patient was treated by vessel sacrifice.
一种自膨胀支架最近被引入用于治疗宽颈动脉瘤。我们描述了两例支架在大型动脉瘤内位置不当的病例。在第一例中,支架在微导管插入过程中移位。通过在第一个支架的间隙中放置第二个支架,随后进行动脉瘤栓塞来处理。在第二例中,支架展开后,当交换导丝被移除时,支架近端移入动脉瘤内。该患者接受了血管牺牲治疗。
