[A case of abdominal aortic aneurysm ruptured into the left common iliac vein with symptoms resembling deep vein thrombosis].

A 59 years old male with abdominal aortic aneurysm ruptured into the left common iliac vein was transferred to us with symptoms resembling deep vein thrombosis of the left lower extremity, such as leg pain, swelling and dilatation of the superficial veins. At operation, a Fogarty's occlusion catheter was inserted through the right greater saphenous vein into the inferior vena cava and inflated concomitantly during aortic clamp to prevent pulmonary embolism which may be caused by the dislodged thrombi from the aneurysm, and as well as to control back-flow-bleeding from the central. The fistula (3.0 X 1.0cm) was closed from inside of the aneurysm using the inferior wall of the aneurysm. The blood from the fistula was collected by the Cell Saver and re-transfused to the patient. The abdominal aorta was replaced with a Dacron Y-shaped prosthesis. The postoperative course was uneventful. CTR on chest X-ray subsided from 51% to 42%, cardiac output normalized from 11l/min to 6l/min, and symptoms resembling the deep vein thrombosis disappeared.
