[Venous aneurysms].

Venous aneurysms are a rare condition. It is an independent nosological unit which differs from varicosities by the following signs: it is not sex- or age-linked, it is found also in children, it can affect any vein, it is found as a solitary lesion and is not associated with prolongation of the affected vein. The therapeutic approach is surgical extirpation. The most serious clinical manifestation can be pulmonary embolism. The author presents four of his own observations with localization on the external jugular vein, the v. cephalica antebrachii, the anterior tibial vein and v. dorsalis digiti manus.
