Clinical diagnosis and treatment of 10 cases of congenital inferior vena cava malformation

Objective To analyze the clinical characteristics and significance of congenital inferior vena cava malformation (IVCM). Methods The clinical data of IVCM from 2013 to 2018 were studied. The clinical manifestations, diagnostic methods and characteristics were analyzed. Results There were 2 cases of double inferior vena cava (DIVC), 3 cases of LIVC, 1 case of LIVC + DIVC, 1 case of IVCA, 1 case of LIVC + IVCA near cardiac segment, 1 case of reentrant inferior vena cava (RIVC) and 1 case of linear inferior vena cava (IVC). Among them, 6 cases were complicated with DVT, 3 cases were misdiagnosed as budd-chiari syndrome (BCS), and 1 case was complicated with severe deep venous insufficient (DVI). Conclusion IVCM is rare and often ignored because of nonspecific manifestations, but it is an important risk factor for many diseases. It has important clinical significance in abdominal, pelvic and retroperitoneal surgery and vascular interventional therapy. Neglecting may lead to serious consequences.
