Induced thrombosis of inoperable abdominal aortic aneurysm.

摘要: On occasions it may be vital to produce controlled thrombosis of an abdominal aortic aneurysm when resection is not possible. A successful technique was evolved achieve this in a 57-year-old man with malignant lymphoma. The tumor found infiltrate massively the retroperitoneum and wall large aneurysm. deemed technically unresectable at operation. An approach devised thrombose proceed safely chemotherapy axillobifemoral bypass made limbs anastomosed end common femoral arteries. external iliac vessels were exteriorized through wall. aneurysmal sac outflow occluded by balloon catheters introduced vessels. right transaxillary catheter inserted placed level renal arteries induce control progress thrombus formation such way as ensure patency Thrombin delivered into via catheter. high urinary output maintained. Serial angiograms clotting process obtained. Once thrombosed, removed final angiogram obtained which demonstrated obliteration patient has been fully employed for 20 months.
