1/59. In situ repair of a secondary aortoappendiceal fistula with a rifampin-bonded Dacron graft.

    Secondary aortoenteric fistulas remain challenging diagnostic and therapeutic problems. Although the duodenum is most frequently involved, other intestinal segments are possible sites for fistulization. We report here a case of graft-appendiceal fistula revealed by recurrent gastrointestinal bleeding 11 years after abdominal aortic aneurysm replacement. The preoperative diagnosis was not achieved by endoscopy or imaging assessment. Despite recommended principles of total graft excision and extraanatomic bypass, appendectomy and in situ rifampin-bonded graft reconstruction were performed because of the advanced age and poor arterial runoff. The postoperative course was uneventful and the patient remains well 17 months after operation.

2/59. Primary aorto-duodenal fistula secondary to infected abdominal aortic aneurysms: the role of local debridement and extra-anatomic bypass.

    Gastrointestinal bleeding secondary to spontaneous rupture of an infected abdominal aortic aneurysm into the duodenum is a rare and highly lethal clinical occurrence, representing roughly a third of all primary aortoduodenal fistulas. diagnosis is problematic due to the subtleties in the clinical presentation and course, and surgical treatment is usually delayed, representing a challenge even for the experienced vascular surgeon. The overall mortality is over 30% and the operative approaches are still controversial. Two cases of ruptured infrarenal aortic aneurysms complicated with aortoduodenal fistula were recently treated at our institution. Bacterial aortitis was documented by arterial wall cultures positive for klebsiella and salmonella species respectively. The clinical courses and outcomes of the two patients (one survivor ) treated with retroperitoneal debridement and extra-anatomic bypass and a review of the modern surgical treatment are herein described.

3/59. Tuberculous infection of the descending thoracic and abdominal aorta: case report and literature review.

    We report here a case of infrarenal aortic disruption and aortoduodenal fistula secondary to tuberculous aortitis in a 77-year-old man. From a review of experience with operative management of tuberculous infection of the descending thoracic and abdominal aorta reported in the English-language literature, including the current report, we found that operative repair was attempted in 26 patients with tuberculous aortitis of the abdominal (n = 16), thoracic (n = 8), and thoracoabdominal (n = 2) aorta. Six patients had emergent operations for massive hemoptysis (n = 2), aortoduodenal fistula (n = 2), or abdominal rupture (n = 2), with an associated 30-day mortality of 50%. Elective or semi-elective repair was undertaken in 20 patients, of whom 19 (95%) survived for at least 30 days. On the basis of limited experience with this rare entity, in situ graft replacement is an appropriate treatment of tuberculous aneurysms and pseudoaneurysms of the descending thoracic and abdominal aorta.

4/59. Two cases of aorto-gastrointestinal fistula.

    We report two cases of aorto-gastrointestinal fistula. Case 1, a 60-year-old man, suffered from repeat hematemesis. He was preoperatively diagnosed as aortoesophageal fistula with thoracic aortic aneurysm and was successfully treated by graft replacement of the aneurysm. Case 2, a 73-year-old man, presented with massive gastrointestinal bleeding, yet repeat endoscopical examination did not reveal the origin of the bleeding. He died of catastrophic hematochezia. The pathological findings at autopsy revealed an aortoduodenal fistula. These two cases suggested the importance to consider an aorto-gastrointestinal fistula in the differential diagnosis of patients presenting gastrointestinal hemorrhage.

5/59. An embryological perspective on congenital portacaval shunt: a rare anomaly in a patient with hepatocellular carcinoma.

    We describe a 42-yr-old woman with hepatocellular carcinoma and a congenital portacaval shunt. A computed tomography (CT) scan of the abdomen showed a prominent left hepatic lobe extending into the lower abdomen. A large encapsulated, necrotic-appearing mass was seen within the right hepatic lobe. The patient underwent hepatic resection, during which the continuation of the confluence of the splenic and superior mesenteric veins was found to empty directly into the inferior vena cava, bypassing the hepatic parenchyma. An extended right hepatic lobectomy was performed with a complete excision of the mass (T3 N0 M0, stage III). The patient had an uneventful postoperative course. To our knowledge, this is the first reported case of this anomaly in a living adult having undergone hepatectomy.

6/59. Endovascular stent graft for management of ureteroarterial fistula after orthotopic bladder substitution.

    We describe the first case of an ureteroarterial fistula developing after orthotopic neobladder substitution and its minimally invasive management using endovascular stent grafting. We outline the risk factors for the development of ureteroarterial fistulae and trace the evolution of diagnostic and therapeutic modalities used in the management of these life-threatening complications. Minimally invasive management with endovascular stent grafting and exclusion of two pseudoaneurysms in the iliac artery system was performed successfully. After successful endovascular exclusion of two pseudoaneurysms, the patient's hematuria resolved and he recovered fully. Three-dimensional computed tomography performed 3 months later documented a patent aortoiliac arterial system without evidence of pseudoaneurysm or endovascular leak. Ureteroarterial fistula after orthotopic bladder substitution was managed with an endovascular stent graft without the need for extra-anatomical vascular bypass. Early recognition, stabilization, and angiographic evaluation followed by this minimally invasive technique may avoid open operative repair and attendant morbidity.

7/59. Combined resection of the thoracic esophagus and thoracic descending aorta.

    We conducted combined resection of the thoracic esophagus and thoracic descending aorta in 2 patients, one with advanced esophageal cancer with aortic invasion and the other aortoesophageal fistula caused by a false aortic aneurysm. Combined resection of esophageal tumor and adjacent involved organs was conducted in 14 patients with A3:T4 esophageal cancer but none survived 3 years and resecting tumor-invaded organs did not improve patient survival. One major problem of combined resection of the esophagus and aorta is contamination of the posterior mediastinum. In 1 patient, 2-stage surgery for the esophagus and in situ aortic replacement was conducted to reduce operative risk and avoiding infection of the prosthetic vascular graft. With thoracic descending aortic aneurysm adjacent to the esophagus on the increase, cardiovascular surgeons should prepared to undertake combined resection of both the aorta and esophagus.

8/59. Intraoperative localisation and management of coronary artery fistula using transesophageal echocardiography.

    Coronary artery fistula is a rare congenital malformation that can be complicated by intracardiac shunts, endocarditis, myocardial infarction, coronary aneurysm and sudden death. Clinical symptomatology depends upon the underlying anatomy and the size of the fistulous connection between the left or right side of the heart. We report the successful management of a giant right coronary artery with fistulization into the right atrium. Intraoperative transesophageal echocardiography with colour flow Doppler was used for precise location of the fistulous communication, selective demonstration of vessels feeding the fistula and documentation of abolition of fistulous flow all without the need for cardiopulmonary bypass. Furthermore the effect of shunt occlusion on regional wall motion was documented which facilitated the successful ligation of the fistula.

9/59. Aortoesophageal fistula caused by aneurysm of the thoracic aorta: successful surgical treatment, case report, and literature review.

    Aortoesophageal fistula induced by atherosclerotic thoracic aortic aneurysm is rare, but is usually a fatal disorder, with few survivors reported. We report the case of a 72-year-old man with aortoesophageal fistula successfully treated in a two-stage operation. In the first stage, we performed resection and replacement of the aortic aneurysm with a prosthetic graft in situ, esophagectomy, cervical esophagostomy, and jejunostomy. After the patient recovered well postoperatively, a transmediastinal retrosternal interposition of the stomach was performed, with esophagogastroanastomosis in the cervical area, to re-establish the gastrointestinal tract. We include a discussion of the causes, diagnostic approach, management of the aorta and esophagus, and review of the literature.

10/59. Primary aortoduodenal fistula treated successfully with surgery in a patient with Takayasu's arteritis.

    Takayasu's arteritis was originally described as a systemic inflammatory arterial disease presenting with occlusive changes. However, it has also been known to cause aneurysm formation. In this report, a patient with Takayasu's arteritis was found to have an aortoduodenal fistula. An emergency operation was carried out with resection of the saccular aneurysm and the fistula. The aorta was reconstructed with a prosthetic graft and the duodenum repaired. A pedicled omental flap was placed between the aorta and the duodenum. The postoperative recovery was uneventful, there was no evidence of persistent bleeding, and the patient was well at the 3-year follow-up. This is the first case in the English language literature of a primary aortoduodenal fistula treated successfully with surgery in a patient with Takayasu's arteritis.
