title: New treatments for infrapopliteal disease: devices, techniques, and outcomes so far.
abstract: The use of endovascular treatment of infrapopliteal disease has increased in popularity in recent years. An improvement in technical success rates due to the availability of newer devices has fuelled an increased interest in the subject. The pathogenesis, indications for treatment, and outcome measures of infrapopliteal disease differ from larger vessel intervention. Diabetes and renal failure are prevalent. Neuropathy and venous disease contribute to the etiology of ulceration. Most interventions are undertaken for critical limb ischemia rather than claudication. Therefore, a range of conservative, pharmacological, and invasive therapies are provided. Conventional percutaneous transluminal angioplasty (PTA) using modern low-profile systems is associated with high technical success rates. However, initial data from recent randomized, controlled trials suggest that drug-eluting stents are consistently achieving improved patency over PTA alone or over bare metal stents. This review summarizes recent advances in the treatment of infrapopliteal disease.
