Although balloon angioplasty for the management of failing bypass grafts has been well documented, little mention has been made of its use in treating the occlusive lesion within the native artery after a failed bypass graft. We report our experience with five patients in whom successful balloon angioplasty was carried out subsequent to failure of a femoral popliteal bypass graft. Increasingly aggressive percutaneous therapy of arterial occlusive disease may now be expanded to include a unique group of patients with chronically failed bypass grafts and occlusive disease within the native artery conducive to percutaneous transluminal angioplasty. This group of patients would previously have been relegated to repeat bypass grafts with its inherently inferior patency and recognized added technical demands. Percutaneous balloon angioplasty appears to be a plausible alternative in selected cases for repeat lower extremity revascularization.

Rupture of the iliac artery during percutaneous angioplasty is a life-threatening condition that requires prompt diagnosis and treatment to rescue the patient. Recently, percutaneous angioplasty has become an outpatient procedure, but there is no reliable guideline for observation time in the hospital after percutaneous angioplasty. We describe a 67-year-old man with bilateral lesions in the iliac artery who experienced a delayed rupture of the iliac artery 2 days after percutaneous balloon angioplasty and placement of a self-expandable stent. The patient was successfully treated by endovascular intervention with a stent graft. In our department, percutaneous angioplasty is not performed in an outpatient clinic, and all patients are admitted to the hospital and observed for at least 3 days after percutaneous angioplasty. Because our patient was in the hospital when the iliac artery ruptured, prompt diagnosis and treatment were possible. Moreover, because appropriately sized stent grafts were prepared in the hospital, timely endovascular treatment could be performed, and the patient recovered successfully. From this case, we conclude that observing patients for a sufficient time in the hospital and preparing appropriately sized stent grafts are 2 important factors for the safety of patients who undergo percutaneous angioplasty.
