The authors analysed the results of examination and dynamic follow up (from 2003 to 2011) of twenty-one 15-to-55-year-old male patients presenting with hypoplasia or aplasia of the inferior vena cava. The diagnosis was verified by means of SCT- or MRT-phlebography.

The disease was newly diagnosed at the age of 15–55 years (mean 25.9±2.6). The pathology manifested itself as a clinical course of thrombosis of deep veins of lower limbs in 16 (76.2%) patients and by oedema thereof in 5 (23.8%) subjects.

Of the 16 patients with symptomatology of deep vein thrombosis, 13 patients had proximal (iliofemoral) thrombosis and 3 patients had distal thrombosis. In the overwhelming majority of the patients, the pathological process was localized on the right.

All the patients after 1.5-12 months developed signs of impaired patency of the IVC. 1.5–2.5 years later, the course of chronic venous insufficiency was complicated by the development of trophic ulcers of the crus in eight (38.1%) patients.

Congenital abnormalities of the IVC are encountered predominantly in males, remaining for a long time latent to be newly manifested in the young age by symptoms of deep vein thrombosis (more often by right-sided iliac-femoral thrombosis). Suspecting this pathology should be followed by extended examination using SCT- or MRT-phlebography.

KEY WORDS: malformation, hypoplasia, aplasia, inferior vena cava, SCT-phlebography, MRT-phlebography, deep vein thrombosis.
