The elephant trunk procedure is used to close the false lumen of the distal aorta in the surgical treatment for aortic dissection. We examined the state of the false lumen thrombus and measured the diameter of the aortic dissection, using postoperative digital subtraction angiography and computed tomographic scanning. We performed the elephant trunk procedure in 24 cases in the period, between January 1995 to December 1999. Total aortic arch replacement was performed in Stanford type A dissection, and descending aorta replacement was performed in Stanford type B dissection. In all patients, thrombotic closure around the elephant trunk graft was confirmed. Thromboexclusion of the false lumen of the descending aorta was observed in 18 cases (75.0%). The secondary operation may be unnecessary, because there was a tendency towards reduction of the diameter of dissecting aorta. These data revealed that this procedure was effective. In 6 cases (25.0%), residual dissection was recognized in the thoracoabdominal aorta, but there was no case of expansion requiring further operation. Nevertheless, careful follow-up is necessary, because aneurysms could expand in the future.

A 24-year-old woman had been injured in an automobile accident. The chest X-ray showed widening of the mediastinum and computed tomography showed mediastinal hematoma around the aortic arch. Aortic rupture was suspected, so we performed aortography, which revealed pseudoaneurysm of the descending aorta. Moreover, she also had splenic rupture and pelvic fracture. She underwent an emergency operation 4 hours after the accident. Medial tear of the descending aorta was replaced with a graft under temporary bypass without heparin. Simultaneously, splenectomy was performed. Her postoperative course was uneventful. We consider that temporary bypass without heparin is a useful method during repair of the descending aortic rupture due to trauma.

Infectious arterial aneurysm in a rare condition with a high mortality because of rapid aneurysmal growth and subsequent rupture. We encountered 3 cases of arterial aneurysm due to Salmonella infection. We evaluated there 3 cases and an additional 14 cases reported in the Japanese literature. Eleven patients with Salmonella infection had bacteremia. The incidence of bacteremia in patients with Salmonella infection was more frequent than that in patients with other bacillary infections. The location of the aneurysm was the abdominal aorta in 14. Rupture or impending rupture of the aneurysm was identified in 12. Fifteen patients underwent operation including in situ reconstruction in 9 and extra-anatomic bypass in 6. Among 15 patients who underwent an operation, 14 survived. These data suggest that accurate preoperative diagnosis, long-term antibiotic therapy, and immediate surgical intervention are essential for effective treatment of arterial aneurysm due to Salmonella infection.

A 73-year-old man who had undergone Y-grafting suffered from septicemia. A culture of arterial blood yielded Bacteroides fragilis. Computed tomography showed abscess and gas around the prosthetic graft. Under a diagnosis of a prosthetic graft infection caused by Bacteroides fragilis, removal of the infected graft, extra-anatomic bypass and omental grafting were performed 13 days after the first operation. After intensive treatment, he recovered and was discharged on the 45th day postoperatively.

A 71-year-old woman who had Takayasu's disease underwent Y-grafting, bypass grafting between the abdominal aorta and left renal artery with 8mm ePTFE graft and right nephrectomy for infrarenal abdominal aortic aneurysm and renovascular hypertension (RVH). Four years after the first operation, the bypass graft became occluded and hypertension was exacerbated. Magnetic resonance angiography revealed that the left renal artery was supplied by the collateral arteries. We performed replacement of the thoracoabdominal aorta and reconstruction of the left renal artery using the saphenous vein. Postoperatively serum creatinine level decreased and hypertension was controllable. She was discharged from the hospital and has been well for three years.

A 52-year-old man who had liver cirrhosis sufferred ruptured thoraco-abdominal aortic aneurysm. This patient was classified as having Child's class B liver cirrhosis preoperatively. The thoracoabdominal aorta was successfully replaced with reconstruction of the renal arteries, superior mesenteric artery, celiac artery, and 10th intercostal artery. Omentopexy was added. As persistent ascites continued postoperatively, peritoneovenous shunting was performed on the 29th postoperative day. Ascites disappeared and 20 days later the patient was discharged from hospital and has been well for two years.

A 59-year-old man presented with severe abdominal pain. CT scan showed a type A aortic dissection and pericardial effusion. As cardiac tamponade was present, emergency total arch replacement was performed. Because of his symptom, we added an exploratory laparotomy, which revealed intestinal necrosis. Therefore, necrotic intestine 4.5m in length was resected. After intensive care, he began oral feeding on the 25th day and was discharged on the 76th day postoperatively.
