Below the knee percutaneous transluminal angioplasty for claudicants: One vessel is enough to relieve symptoms.

Among patients with lower extremities arterial disease (LEAD), treatment of below the arteries has been historically limited to the treatment of chronic limb-threatening ischemia (CLTI), as recommended by available guidelines. In this study, the authors provided new data on the role of different endovascular revascularization anatomical strategies of the below the knee (BTK) arteries adopted in claudicant LEAD patients. The revascularization of the anterior tibial artery seems more effective for symptoms relieves than of the posterior territories and most of the adverse events occurred in the follow up period were target vessel revascularization, suggesting that revascularization of single vessel is enough to achieve clinical success.
