Arteriographic findings in diabetic and non-diabetic with critical limb ischemia.

Objective: To compare angiographic findings of diabetic and non-diabetic patients with critical limb ischemia.

Methods: We included 161 patients with infrainguinal critical limb ischemia (CLI). We evaluated the clinical and arteriographic (number and presence of opacification of leg arteries) of the two groups of patients. Statistical analysis was performed using EPI-INFO.

Results: Most patients were category 5 of Rutherford's Classification and had femoropopliteal disease. Seventy-two percent of non-diabetic and 67% of diabetic had opacification of the fibular artery (p = 0.25), this is the most present artery in both groups. Diabetic patients had less opacification of the posterior tibial artery in the univariate analysis (29% vs. 47%, p = 0.008). But only female sex showed a significant risk for the absence of the posterior tibial artery in logistic regression (OR = 2.6; p = 0.01).

Conclusion: The peroneal artery was the most frequently artery in angiograms of diabetic and non-diabetic patients with CLI. Diabetic and non-diabetic patients did not differ in angiographic findings of the leg.
