Abstract

OBJECTIVE:

To evaluate the impact on wound healing and long-term clinical outcomes of endovascular revascularization in patients with critical limb ischemia (CLI).

MATERIALS AND METHODS:

This is a retrospective study on 189 limbs with CLI treated with endovascular revascularization between 2008 and 2010 and followed for a mean 21 months. Angiographic outcome was graded to technical success (TS), partial failure (PF) and complete technical failure. The impact on wound healing of revascularization was assessed with univariate analysis and multivariate logistic regression models. Analysis of long-term event-free limb survival, and limb salvage rate (LSR) was performed by Kaplan-Meier method.

RESULTS:

TS was achieved in 89% of treated limbs, whereas PF and CF were achieved in 9% and 2% of the limbs, respectively. Major complications occurred in 6% of treated limbs. The 30-day mortality was 2%. Wound healing was successful in 85% and failed in 15%. Impact of angiographic outcome on wound healing was statistically significant. The event-free limb survival was 79.3% and 69.5% at 1- and 3-years, respectively. The LSR was 94.8% and 92.0% at 1- and 3-years, respectively.

CONCLUSION:

Endovascular revascularization improve wound healing rate and provide good long-term LSRs in CLI.
