A technique for the creation of long autogenous tissue arterial patches.

An endarterectomized segment of an occluded artery (e.g. superficial femoral artery), is an alternative autogenous material for patch angioplasty which preserves the continuity of the saphenous vein. A technique of incising endarterectomized segments of superficial femoral artery in a spiraled manner is presented which allows for the creation of long autogenous tissue patches. A spiral is drawn on the exterior of a harvested arterial segment which is either 1 cm, 7 mm or 5 mm in width. When incised along the spiral, the length of the resulting elliptical patch will be two, three, or four times, respectively, the length of the original artery segment. The authors have used the technique to close extended profundoplasty in three patients and for construction of a patched distal anastomosis in two patients undergoing prosthetic femoropopliteal bypass grafting. There have been no early complications.
