AIM: The authors aimed to assess clinical results following percutaneous transluminal angioplasty (PTA) of pedal arteries and digital branches in order to avoid minor amputations or support surgical skin incisions, in patients with CLI and distal wounds on the toes.
METHODS: Baseline, procedural and mid-term outcome data of all consecutive patients with CLI and ulcerative lesion on the toes, in which endovascular treatment of the foot arteries and digital branches was attempted, were prospectively collected between January 2010 and January 2011. The primary end-point was acute success (i.e. technical, angiographic and procedural success). Secondary end-points included limb, foot and toes salvage rates, minor amputations, reocclusion/restenosis and repeat treatment.
RESULTS: 1057 consecutive patients with CLI were treated and in 24 cases (2.3%), after tibial and foot arteries PTA, related to the presence of arterial lesion (stenosis/occlusion) in the digital branches, the recanalization of the target vessel was performed. Acute technical success was achieved in 100% of cases, with adequate angiographic results without peri-procedural complications. Clinical improvement was obtained and maintained after an average of 9 months. Amputation was avoided in 9 patients (37.5%), in 8 patients (29.6%) amputation involved only a distal phalange, in 5 patients (20.8%) toe amputations was necessary, in 2 patients (8.4%) trans-metatarsal amputation was performed. No below the ankle (BTA) or major amputations were performed.
CONCLUSION:Endovascular recanalization of digital branches in patients with CLI and distal wounds on the toes is feasible and safe; represent a support to avoid minor amputations or surgical skin lesion healing.
