Local and systemic complications after percutaneous interventions in the treatment of peripheral arterial occlusive disease

Complication rates data following percutaneous interventions for the treatment of peripheral arterial occlusive disease (PAOD) vary in the literature, with values between 2.4 and 18.1% described. This includes puncture-related complications as well as systemic complications, e.g., cardiovascular events. Given the considerable importance of intervention techniques in PAOD treatment, with an increasing application in the ambulatory sector, against a backdrop of a group of patients with many comorbidities, awareness of potential risk factors and the prevention of any possible complications is important. Almost 90 % of complications occur during the first 24 h after the intervention. The occurrence of complications thus correlates with a worse outcome based on 30-day and 1-year mortality rates, as well as amputation rates. However, the lack of application of uniform terminology makes it difficult to collect, and in particular, to compare, the outcomes. This article is therefore aimed at providing an overview of possible complications of percutaneous interventions in PAOD therapy, and to classify them in the clinical context, taking into account potential risk factors.
