[Venous aneurysms].

Incidence, etiology, diagnostic procedures and therapy of venous aneurysms, basing on 152 own cases, are discussed. The main procedure for diagnosis is phlebography. It must be distinguished between aneurysms of epi- and subfascial veins. The localization determines the surgical procedure which represents the only successful therapy. Without proper treatment, venous aneurysms may be responsible for complications such as thrombophlebitis, thrombosis with pulmonary embolism, aneurysm rupture and compression of adjacent structures. The results of surgical treatment are excellent.
