Infrapopliteal Intervention for the Treatment of the Claudicant

Abstract

As the associated risks of infrainguinal balloon angioplasty and stenting have fallen and the relative success rates have risen in recent years, the threshold for offering endovascular treatment to patients with claudication has significantly decreased. Patients once considered appropriate only for risk-factor modification, exercise therapy, and medical treatment are now increasingly being offered percutaneous revascularization as a primary treatment option. Similarly, occlusive disease of the tibial vessels, once thought to be the exclusive domain of operative bypass, is increasingly being treated percutaneously. Over this same period, results of operative infrainguinal arterial reconstruction have also considerably improved. In modern times, excellent outcomes following bypass grafting with autogenous vein to the tibial level have been demonstrated, with morbidity, mortality, and long-term patency equivalent to that of more proximal bypasses. Evidence supports the view that the anatomic level of the distal anastomosis is less critical to the long-term outcome of the procedure than factors such as operative indication and conduit quality. Within the context of this changing climate, it is an appropriate time to examine and potentially redefine the role of both endovascular and open surgical intervention for a population that has not traditionally been offered revascularization, patients with claudication secondary to infrageniculate occlusive disease.
