Influence of diabetes mellitus on results of infrainguinal artery bypass for chronical ischemia of the lower extremities / 中国普通外科杂志

ABSTRACT

Objective To evaluate the efficiency and safety of infrainguinal arterial bypass in diabetic ischemia of the lower extremities. Method Eighty-two consecutive patients undergoing lower extremity arterial reconstruction from 2002 to 2005 were divided into diabetes group (DM) and nondiabetes group ( NDM ) . Graft patency, limb salvage, and perioperative complications were compared between the two groups. Results There were 82 patients receiving 86 grafts, 44 grafts (51. 2% ) in patients with diabetes (DM group) and 42 (48. 8% ) in nondiabetic patients (NDM group). Average age of the DM group was (68?10) years, vs. (63?12) years of NDM group (P=0.025). In-hospital perioperative mortality was 3. 7% ( DM group 4. 8% vs. NDM 2. 5% ,P = 1. 000). Cumulative primary and secondary graft patency in 4 year was 44% in DM group and 64% in NDM group, P =0. 112 and 69% in DM group, 66% in NDM group, P = 0. 083) , respectively. The 4 year overall limb salvage rate was not statistically defferent ( DM group, 68%; NDM group, 66%; P =0.114). Conclusions Diabetes mellitus does not influence perioperative mortality, graft patency, or limb salvage rates after lower extremity arterial bypass.
