The diabetic patient has a higher benefit from infrapopliteal revascularization than the non-diabetic patient: A 10-year retrospective study

Abstract

The objective of this article is to evaluate the limb salvage and patency rates after crural arterial revascularization, differences between graft material and co-morbidities. All patients with crural artery bypasses were analysed retrospectively in a single centre (Department of Vascular Surgery, Thüringen Kliniken Saalfeld, Rudolstadt, Germany) over a 10-year period (1996-2006); 157 patients with 170 consecutive arterial reconstructions could be included. Follow-up time was 55 months (6-119). Median age of the 56 women and the 101 men at the time of operation was 70 years (45.6-93.6). The five-year secondary patency rates were 71.5 ± 6.22% (vein), 44.3 ± 10.8% (composite; p = 0.0011), 52.6 ± 13.4% (prosthetic graft with distal vein cuff/patch; p = 0.00953) and 42 ± 12% (prosthetic graft without distal vein cuff/patch; p = 0.00443). Limb salvage rates after five years were 79.5 ± 5.8%, 61.6 ± 10.3%, 77.9 ± 11.3% and 70.1 ± 14.7%, respectively. Cumulative limb salvage rate was significantly higher in diabetic patients (78.9 ± 4.9%), than in non-diabetic patients (66.6 ± 6.8); p = 0.023. Crural reconstruction is a suitable method for peripheral arterial occlusive disease to prevent amputation, particularly in diabetics.
