Effect of recanalization of anterior tibial artery and peroneal artery on targeted angiosomes of posterior tibial artery in the foot through different aspects

Abstract

Objective The purpose of this study is to evaluate the outcome of percutaneous transluminal angioplasty of ipsilateral peroneal artery and the anterior tibial artery for revascularization of targeted angiosomes in the vascular territory of posterior tibial artery (PTA) in the foot, through interconnecting branches, and the resulting effect on existing wound healing and limb salvage, in comparison with the effect of percutaneous transluminal angioplasty on PTA alone on revascularization and wound healing in these angiosomes. Patients and methods We included 80 patients for 80 angioplasty procedure (80 limbs) who were divided into two equal groups. Group A included patients with peroneal and anterior tibial patent vessel runoff, who were fit for percutaneous transluminal angioplasty for both vessels, whereas group B were candidates for PTA angioplasty. We studied the arterial supply in 80 limbs with TASC C-D lesions with follow-up along 1 year, all with PTA occlusion. Patients with single-vessel or three-vessel runoff were excluded from the study. Outcome measures included wound healing of targeted angiosomes of PTA with complete epithelialization of the affected lesion with or without secondary interventions such as debridement or skin grafting and limb salvage with absence of major amputation. Conclusions We found that recanalization of peroneal artery together with anterior tibial artery can supply angiosomes of PTA and accelerate wound healing through communicating branches in the foot with comparable outcome on wound healing and decreased incidence of major amputation to single recanalization of PTA as primary and secondary outcome, obviating the need for lengthy and more risky interventional procedure.
