[Venous Aneurysms of the Lower Extremities - Clinical Significance and Therapy].

Isolated venous aneurysms are very rare. In clinical practice it is predominantly seen in the course of a random diagnosis to find the cause of pulmonary embolism or venous thrombosis. Due to an increased use of duplex scans there is also an increase in the number of diagnoses of venous aneurysms even if patients are still asymptomatic. The precise prevalence is yet unknown. The choice of therapeutic procedure is dependent on each individual clinic as well as the size and morphology (fusiform or saccular) of the aneurysm. At present, the available data are still insufficient. We discuss our own surgical treatment of 7 patients with primary aneurysms involving the vena cava, iliac vein, great saphenous vein junction and popliteal vein in consideration of the latest literature.
