[Short distal origin vein graft in diabetic foot syndrome].
OBJECTIVE
World wide increase of diabetes compound with diabetic foot syndrome becomes a challenge in vascular surgery to avoid limb loss. In diabetics a special pattern of atherosclerosis is prevalent with disease limited to the infrageniculate arteries but sparing inflow vessels and distal tibial and pedal arteries. This provides short bypass grafting from popliteal to tibial and pedal arteries, a concept first described by F. Veith in 1981.


METHODS
Diabetics with severe atherosclerotic disease and limb-threatening ischemia got general evaluation and vascular imaging. Falling in this special category the patients underwent short vein bypass grafting originating at the first or third popliteal segment extending to the tibial or pedal arteries. Follow up of patency and limb salvage was nearly complete.


RESULTS
From 1988 to 2001 124 diabetics received 140 vein bypass grafts for limb salvage, 95.7% already preoperatively with foot necrosis. Operative mortality rate was 1.4%, major morbidity rate was 9.3%, early graft failure rate 8.5% and early amputation rate was 3.8%. 2 year primary patency, primary assisted patency, secondary patency rates and limb salvage were 73.3%, 75.7%, 76.4% and 87.2%. 5 years results were 63.6%, 69.2%, 70.0% and 81.9% respectively.


CONCLUSIONS
This series revealed exceptionally good results in patients with diabetes mellitus after short vein bypass grafting in concert with earlier studies since 1981. Compared to long femorodistal grafts there was no difference in longterm patency. Bypass grafting in diabetic foot syndrome is still regarded to have a poor prognosis. Just the contrary is the case. This study in concert with former studies revealed distal origin bypass grafting a durable and effective procedure to fight limb loss in diabetic foot syndrome.


CONCLUSIONS
Distal origin vein bypass grafting is an excellent method just for patients with diabetes. Looking at limb salvage rates over 80 % in 5 years, this procedure should be offered more often suitable patients with diabetic foot syndrome.
