Abstract

A 71-year-old man presented to the emergency room with complaints of progressive dyspnoe and pain in both lower extremities. His medical history consisted of multiple idiopathic deep vein thrombosis, familial deafness and cholecystolithiasis. Clinical examination revealed large varicose veins in both lower extremities. A following electrocardiogram, echocardiography and radio graphy of the thorax were normal (not shown). D-dimeren had risen for which an angio CT of the thorax was performed. This showed no pulmonary embolism (not shown). A venous duplex of the lower extremities revealed insufficiency of both the superficial and deep venous system (not shown). An abdominal CT with intravenous contrast injection showed absence of the infrarenal inferior vena cava (Fig. A), absence of the common iliac veins, enlarged ascending lumbar veins (Fig. B) and prominent anterior paravertebral collateral veins (Fig. C) which lead to a prominent azygos vein (Fig. C). A complex venous collateral circulation was found infrarenally (Fig. A) as well as in the abdominal wall (Fig. D). The suprarenal IVC was normal (Fig. E), formed by confluence of the renal veins. Multiple calcifications in the enlarged internal and external iliac veins confirm a history of deep vein thrombosis (Fig. F).
