[The venous aneurysm].
Venous aneurysms are rare: only 311 cases of venous aneurysms and 56 cases of aneurysms in vein transplants have been reported since 1939 to date. 62% of the patients suffering from venous aneurysms were less than 40 years of age. The most frequently involved vessels were the internal jugular vein (n = 56), the portal vein (n = 28), the v. saphena magna (n = 30) the popliteal vein (n = 23), the azygos vein (n = 22) and the vena cava superior (n = 20). The diameters of the aneurysms were between 1 and 16 cm. Symptoms, if at all noticeable, depend on the localisation of the aneurysm, but they are unspecific in the majority of cases. The most frequent finding was the space- occupying growth seen in 190 patients (52%). Pulmonary embolisms originating from venous aneurysms were seen in 19/311 (6.1%), a rupture of an aneurysm in 4/311 (1.2%) of the venous aneurysms and 5/56 (8.9%) of the aneurysms in transplant veins, respectively. and were fatal in 1 (0.3%) and 2 (3.6%) of the cases, respectively. Of the 205 patients who were operated on, 3 (1.5%) died from intraoperative complications.
