Appropriate Strategy of Surgical Treatment in Ischemic Diabetic Foot

Appropriate Strategy of Surgical Treatment in Ischemic Diabetic Foot

This cohort study aims to evaluate the outcomes of appropriate surgical treatment strategies in diabetic foot ulcers with different rate of popliteal artery stenosis(<50% or ≥50%). In this study, patients with Texas university grade 2-4(stage C-D) ischemic diabetic foot ulcers will be included. Data of patients who underwent surgical treatment in the past will be retrospectively collected. The patients with follow-up time less than 12 months will continue to follow up. Also the postoperative patients will be prospectively collected. Effects of different surgical strategies, including wound healing therapy, interventional therapy and tibial transverse bone transport therapy will be measured by several indexes.
