Abstract:
Background: The aim of the study was to evaluate the role of endovascular revascularization of the pedal vessels in diabetic patients with ischemic limbs on the rate of wound curing and healing and saving limbs.
Methods: prospective interventional study over a period of 30 months, 63 diabetic patients presented with critical limb ischemia (CLI), subjected to angiography showed pedal arch defect in three groups: complete pedal arch (CPA), incomplete pedal arch (IPA), and absent pedal arch (APA), and need revascularization. The rate and time of tissue healing and preservation of limb and avoid amputation were assessed using Kaplan–Meier curves between the different groups.
Results: all patients in the study were divided into three groups, CPA group 22 patients (34.9%), IPA 28 patients (44.5%), and APA group 13 patients (20.6%), with no difference statistically in age, gender and other chronic illness. The rate of healing and time consumed for curing in CPA patients was remarkably than other, 90% in CPA, 69% in IPA, and 54% in the APA group (P=0.004). The time consumed was (3.7 + 2.3, 4.2 + 2.8 and 6.2 + 3.4) respectively (p=0.03) for healing. While the limb preservation rate was magnificent in CPA patients (100%), (86%) in IPA, and (61.5%) in APA group; P=0.01). no need for minor surgical intervention was accomplished in 85%, 74.3%, and 46.7% respectively (P=0.065).
Conclusion: The endovascular intervention for dilatation of the pedal vessel has a great influence on saving the diabetic ischemic limbs, tissue preservation and improves their life.
