Our analysis shows that it is not possible to differentiate lymphedema from other lower limb edema sonographically.

Summary: Endovascular arterial revascularisations for the treatment of symptomatic peripheral arterial disease are constantly increasing in importance and number due to the changing age structure and high numbers of comorbidities in the German population. Patients with peripheral artery disease are often at increased risk for peri- and post-procedural complications including severe cardiovascular events. Due to limited financial and human resources and considerable risks of hospitalization, endovascular interventions that were previously reserved for hospitalized patients are now progressively considered to be performed as day case procedures. More than one third of these procedures are performed in Germany by internists with a specialization in angiology. In the current position paper the German Society of Angiology endorsed by the European Society of Vascular Medicine, summarizes the requirements and risk factors to be considered for the planning, safe performance and post procedural care of endovascular revascularizations in outpatients. The performance of endovascular procedures for peripheral artery disease both in hospitalised and outpatients should be accompanied by a mandatory quality assurance process that should not only capture procedural data, but also require documentation of complications and longterm outcome.
