title: Percutaneous atherectomy as an alternative treatment for postangioplasty obstructive intimal flaps.
abstract: 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.
