Intimal flaps are commonly seen angiographically after percutaneous balloon angioplasty. Nonobstructive flaps are normally of little clinical significance, but flaps that obstruct blood flow may lead to partial or complete thrombosis. The Simpson atherectomy catheter was used to treat obstructive intimal flaps after angioplasty in four patients. Lumen patency was reestablished in all four cases. The clinical results were excellent, with rest pain and claudication resolved in all four patients and distal pulses reestablished in one. These findings suggest that the Simpson atherectomy catheter can be used to remove large obstructive flaps complicating angioplasty.
经皮气囊血管成形术后，血管造影常见内膜瓣。非阻塞性内膜瓣通常临床意义不大，但阻塞血流的内膜瓣可能导致部分或完全血栓形成。在4例患者中，使用Simpson旋切导管治疗血管成形术后的阻塞性内膜瓣。所有4例均重新建立了管腔通畅。临床结果极佳，所有4例患者的静息痛和间歇性跛行均得到缓解，1例患者恢复了远端脉搏。这些发现表明，Simpson旋切导管可用于移除使血管成形术复杂化的大型阻塞性内膜瓣。
