Lower-extremity classification system predicts amputation risk in CLI

July 26, 2016

The Society for Vascular Surgery Lower Extremity Guidelines Committee’s new lower-extremity classification system for wound, ischemia and foot infection was effective for prediction of 1-year amputation, wound healing, and reintervention, major amputation or stenosis events in patients with critical limb ischemia treated with infrapopliteal revascularization procedures, researchers reported in the Journal of Vascular Surgery.

Researchers performed a retrospective chart review to identify all patients who underwent infrapopliteal angioplasty for critical limb ischemia (CLI) at the Beth Israel Deaconess Medical Center between 2004 and 2014. During this time, 673 limbs were treated with infrapopliteal endovascular interventions for the following indications: tissue loss (77%), rest pain (13%), stenosis of a previously treated vessel (5%), acute limb ischemia (3%) or claudication (2%). Limbs lacking a grade in any domain of the wound, ischemia and foot infection (WIfI) classification were excluded. The researchers then used the Society for Vascular Surgery (SVS) WIfI classification for 1-year amputation risk to grade the limbs included for analysis.
