[Recanalization of long segment occlusion of superficial femoral artery by percutaneous transluminal laser angioplasty--report of a case].
Percutaneous Transluminal Laser Angioplasty (PTLA) for 46 cm complete occlusion of right superficial femoral and popliteal artery was successfully carried out. Intravenous digital subtraction angiography five months after the procedure showed almost complete recanalization of the arteries, and good flow of the contrast medium through the femoral and popliteal artery. Only Percutaneous Transluminal Angioplasty (PTA) was previously done for the stenosis of right popliteal artery, but restenosis of the artery took place. On this occasion PTLA was carried out to treat stenosis of the popliteal artery as well as the femoral artery lesions. It is speculated that one of the major causes of reocclusion of the femoral and popliteal artery is due to recurrence of a few portions of severe stenosis of superficial femoral and popliteal arteries. This case will illustrate the long term effect of PTLA, because stenotic segments treated only with balloon dilatation recurred, but those stenoses treated with laser did not recur.
