Results of Infrapopliteal Endovascular Procedures Performed in Diabetic Patients with Critical Limb Ischemia and Tissue Loss from
the Perspective of an Angiosome-Oriented Revascularization Strategy
Figure 4
Ischemic ulcer healing at 12 months (a) and limb salvage at 24 months according to an angiosome classification of the ulcers. IR: indirect revascularization without collaterals (blue line); IRc: indirect revascularization through collateral vessels (black line); DR: direct revascularization (red line). The standard error was >10% for the data shown in dashed lines.
