Usage of venous grafts in aorto-iliac reconstructive surgery

The authors present their clinical experience utilizing venous grafts (greater saphenous vein and superficial femoral vein) in the aorto-femoral position.

Span of study is five years. The situations when these techniques were implemented are as follows:-(A). Infected synthetic prosthesis and (B). aorto-iliac occlusive disease in younger patients. A. In synthetic prosthetic infections there are 2 situations: (1) IMMEDIATE INFECTION. Observed in 10 cases, from which 2 cases where of severe infection and 8 cases of superficial infection--localized in the postoperative wound--Scarpa triangle region (7 cases) and left para-rectal (1 case). Superficial infections were treated successfully by daily dressings, excision of necrotic debris, antibiotic-therapy according to local antibiogram (only cases involving local invasion), and of course secondary wound closure at a later on date. The 2 cases of severe graft infection required harvesting of the superficial femoral vein and its usage in the aorto-femoral position. (2) LATE INFECTIONS. 3 patients were diagnosed with late infection of the synthetic prosthesis. In 2 cases, the infection was localized in the Scarpa triangle region, and the third in the abdomen (at the level of the aortic anastomosis). B. Aorto-iliac occlusive disease in younger patients--2 cases benefited from an aorto-bifemoral bypass reconstruction using the superficial femoral vein, and 5 cases where the greater saphenous vein was used in the iliac position.

Only 1 patient with severe prosthetic infection died due to multiple organ dysfunctions after the operation; the rest survived without any major amputation.

the harvesting and usage of these venous grafts is sometimes the final solution for patients with synthetic prosthesis infection.
