title: Current status of interventional radiology treatment of infrapopliteal arterial disease.
abstract: Treatment of infrapopliteal arteries has developed to a standard technique during the past two decades. With the introduction of innovative devices, a variety of techniques has been created and is still under investigation. Treatment options range from plain balloon angioplasty (POBA), all sorts of stent applications, such as bare metal, balloon expanding, self-expanding, coated and drug-eluting stents, and bio-absorbable stents, to latest developments, such as drug-eluting balloons. Regarding the scientific background, several prospective, randomized studies with relevant numbers of patients have been (or will be) published that are Level I evidence. In contrast to older studies, which primarily were based mostly on numeric parameters, such as diameters or residual stenoses, more recent study concepts focus increasingly on clinical features, such as amputation rate improvement or changes of clinical stages and quality of life standards. Although it is still not decided, which of the individual techniques might be the best one, we can definitely conclude that whatever treatment of infrapopliteal arteries will be used it is of substantial benefit for the patient. Therefore, the goal of this review is to give an overview about the current developments and techniques for the treatment of infrapopliteal arteries, to present clinical and technical results, to weigh individual techniques, and to discuss the recent developments.
