Angiographic Evaluation of Peripheral Arterial Occlusive Disease and Its Role as a Prognostic Determinant for Major Amputation in Diabetic Subjects With Foot Ulcers

摘要: OBJECTIVE To evaluate in diabetic patients with foot ulcers the angiographic findings of peripheral occlusive arterial disease and their role as a prognostic determinant for major amputation. RESEARCH DESIGN AND METHODS From 1993 to 1995, 104 inpatients underwent arteriography on ulcerated limb. Stenoses iliac trunk, superficial femoral artery, profunda popliteal anterior tibial posterior peroneal artery were scored basis vessel lumen reduction: 0 if stenoses involved reduction RESULTS causing ≥50% detected 103 (99%). also subjects palpable pulses, ankle-brachial indexes ≥1, or transcutaneous oxygen tension ≥50 mmHg. The risk amputation was increased significantly when total occlusion present infrapopliteal arteries ( x 2 trend = 50.57, P 14. Multivariate analysis indicated high score an independent factor (odds ratio 2.32, 0.001, CI 1.40–3.84). CONCLUSIONS Angiography permits exact detection normal results noninvasive vascular procedures. A that has relevant value can be obtained from evaluation extent diffusion stenoses.
