Abstract

Objective: Describe the characteristics of ankle-brachial index and angiography in patients with critical limb anemia. Methods: Cross-sectional study, describing the ankle-brachial index and angiographic characteristics of 119 patients diagnosed with critical limb anemia at Military Central Hospital 108 and Hanoi Heart Institute from January 2018 – March 2023. Results: The mean ± SD of ABI was 0.35 ± 0.28, in which the majority of patients had the ABI between 0.4 and 0.75 (47.5%) and the ABI less than 0.4 (44.8%). The rate of infrapopliteal lesions was the highest with 40.1%, TASC C (40.9%), TASC B (40.1%), TASC D (15.2%), and TASC A (3.8%). The most damaged arteries were the superficial femoral artery (21.3%), the anterior tibial artery (21.3%), the posterior tibial artery (13.9%). 68.6% of arteries were completely occluded, and 31.4% of arteries were narrowed to more than 50% of the diameter of the lumen. 70.6% of patients had more than 3 damaged arteries. Conclusion: Infrapopliteal lesions were common in patients with critical limb ischemia; arterial lesions were complicated, in multi-level anatomic regions, multi-arterial lesions, and mainly completed arterial occlusion.
