Kobayashi et al evaluated patients following balloon angioplasty for femoropopliteal disease. The presence of certain risk factors can help to identify a patient at risk for arterial restenosis within 2 years. The authors are from Saisikai Yokohama City Eastern Hospital in Japan.
Patient selection: balloon angioplasty for superficial femoropopliteal atherosclerotic disease
Parameters:
(1) type of angiographic dissection after the balloon angioplasty
(2) length of the atherosclerotic lesion in millimeters
Angiographic Evidence of Dissection
Group
none
A
width of dissection < one third of lumen
B
width of dissection > one third of lumen
C
Patients at risk for restenosis:
(1) angiography Group C
(2) angiography Group B AND length of lesion > 100 mm
