Percutaneous transluminal angioplasty of occlusions of the femoral and popliteal arteries by subintimal dissection

A technique for recanalization of femoral and popliteal arterial occlusions by intentional subintimal dissection is described. Recanalization with this technique was attempted in 71 occlusions of the femoro-popliteal segment with a mean length of 11.4cm. Primary technical success was achieved in 54 (76%) cases, with complications occurring in 4 (5.6%). Of 44 successful cases reviewed at a mean follow up of 6 months, 37 (84%) were either asymptomatic or improved. The technique has proved to be an effective method of treating occlusions of the femoral and popliteal arteries with an acceptable complication rate. It may allow successful angioplasty where the standard intraluminal method fails, particularly when reconstructive surgery is the only option.
