Abstract:
Thrombosis of the inferior vena cava (IVC) continues to be a rare event, and there is a scarcity of evidence with regard to its etiology. One source for IVC thrombosis is external compression from adjacent structures. In this case series, we present 1 case of IVC thrombosis caused by a severely distended bladder and a case of external iliac thrombosis caused by external compression from an abnormally enlarged uterus. The treatment of each case is varied and included novel oral anticoagulation, catheter-directed thrombolysis in conjunction with mechanical thrombectomy, or a combination of these. We conclude that the choice of therapy should be tailored on a case-by-case basis.
