Abstract

Objective:

The achievement of single vessel inflow to the wound is an acceptable end point of peripheral vascular intervention for patients with critical limb ischemia (CLI) with tissue loss. However, CLI patients often have multitibial artery lesions. We evaluated the clinical effects of single or double tibial artery revascularization for CLI patients.

Methods:

This study was conducted retrospectively in a single center. Between April 2007 and January 2015, we treated 123 CLI patients (137 limbs) who had lesions in both the anterior tibial artery and the posterior tibial artery. Of these, single tibial artery (anterior or posterior tibial artery) revascularization was performed in 84 limbs (group S) and double tibial artery (both anterior and posterior tibial arteries) revascularization was performed in 53 limbs (group D).

Results:

The wound healing rate was significantly higher (87% vs 79%; P = .003), the time to wound healing was shorter (median, 83 vs 142 days; P = .01), and the repeat peripheral vascular intervention rate was lower (15% vs 35%; P = .03) in group D than in group S. The wound healing rate was nearly similar between the 2 groups in patients with a low clinical stage as assessed by Society for Vascular Surgery Wound, Ischemia, and foot Infection (90% in group D vs 93% in group S; P = .20); however, the wound healing rate was significantly higher in group D in patients with a high clinical stage (85% vs 72%; P = .007).

Conclusions:

The achievement of double vessel inflows to the wound by double tibial artery revascularization positively affects wound healing, particularly in severe CLI patients.
