Venöses Aneurysma als therapeutisches Problem. Behandlungsmöglichkeiten. Die Vorgehensweise bei den gewählten Kranken – unsere Erfahrung

Abstract

Venous system aneurysms appear relatively rarely, and are even more rarely diagnosed, especially if asymptomatic. In the material of our clinic we provide a variety of practices in three patients with venous aneurysms depending on the location, symptoms and main disease. In some patients the occurrence of pulmonary embolism is the first symptom of venous aneurysms, having influence on the selection of further diagnostics, conservative treatment, as well as on endovascular or operating procedure. The proper diagnosis of a venous aneurysm takes place in case of doubling or tripling of the diameter of the basic dimension of the lumen, often with the presence of thrombotic material. Asymptomatic venous aneurysms are usually detected during routine pre-operative diagnosis also including duplex-Doppler studies. In the presence of pulmonary embolism positive angio-CT and scintigraphy raise the suspicion of venous aneurysm unless any other reason is apparent. There is no standard treatment of venous aneurysms. This has to do with the relatively low epidemiology, diversity of location, difficulties in determining the proper primary and secondary aetiology, anatomy and coexisting diseases. Despite the many unknowns a few issues should be considered before appropriate treatment is undertaken. Undoubtedly, the shape itself, the location and size of the aneurysm with the presence or not of thrombotic material are of great value in evaluating the risk of complications, including possibly lethal pulmonary embolism, local symptoms of venous hypertension and possible complications of surgery. In this paper we present 3 patients treated for venous aneurysms located in different regions: popliteal vein, brachial vein and iliac internal vein.
