Simple classification and clinical outcomes of angiographic dissection after balloon angioplasty for femoropopliteal disease

Severe angiographic dissection was associated with future restenosis after balloon angioplasty for femoropopliteal lesions, but mild angiographic dissection was not. Angiographic dissection had more impact on future restenosis particularly in treated long lesions. Stents might not be necessary in short lesions with mild dissection.
