1/21. 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.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm (Clic here for more details about this article) |
2/21. Primary aortoduodenal fistulas in minimally aneurysmal aortas: imaging diagnosis.We report on the utility of computed tomography (CT) in making the diagnosis of primary aortoduodenal fistulas in two cases presenting with massive gastrointestinal hemorrhage. In both cases, the clinical presentation was insidious, no pulsatile abdominal mass was palpated, and endoscopy findings were inconclusive. CT showed minimally aneurysmal aortas communicating with larger areas of contained rupture and pseudoaneurysm stretching adjacent small bowel.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm (Clic here for more details about this article) |
3/21. Stent-graft treatment for bleeding from a presumed aortoenteric fistula.PURPOSE: To describe a technique for the endovascular treatment of aortoenteric fistula. methods AND RESULTS: A 67-year-old man who had undergone aortobi-iliac grafting for aneurysmal disease 8 years previously presented with life-threatening upper gastrointestinal hemorrhage. endoscopy after resuscitation did not identify the source of the bleeding. Computed tomographic (CT) scanning and angiography revealed pseudoaneurysm formation at the upper anastomosis 1 cm below the renal arteries. Measurements were taken for endovascular repair. Uncomplicated emergency aortic endografting for exclusion of the pseudoaneurysm was performed using a 28-mm x 3.75-cm AneuRx device. gastrointestinal hemorrhage ceased. CT scanning at 6 months confirmed the absence of a pseudoaneurysm, and the patient remains symptom free at 18 months. CONCLUSIONS: Endovascular treatment of aortoenteric fistula may represent a technique for treating gastrointestinal hemorrhage and for lessening the morbidity and mortality of open repair.- - - - - - - - - - ranking = 3keywords = pseudoaneurysm (Clic here for more details about this article) |
4/21. Primary aortoenteric fistula related to septic aortitis.CONTEXT: Primary aortoenteric fistulas usually result from erosion of the bowel wall due to an associated abdominal aortic aneurysm. A few patients have been described with other etiologies such as pseudoaneurysm originating from septic aortitis caused by Salmonella. OBJECTIVE: To present a rare clinical case of pseudoaneurysm caused by septic aortitis that evolved into an aortoenteric fistula. CASE REPORT: A 65-year-old woman was admitted with Salmonella bacteremia that evolved to septic aortitis. An aortic pseudoaneurysm secondary to the aortitis had eroded the transition between duodenum and jejunum, and an aortoenteric fistula was formed. In the operating room, the affected aorta and intestinal area were excised and an intestine-to-intestine anastomosis was performed. The aorta was sutured and an axillofemoral bypass was carried out. In the intensive care unit, the patient had a cardiac arrest that evolved to death.- - - - - - - - - - ranking = 3keywords = pseudoaneurysm (Clic here for more details about this article) |
5/21. Mycotic aortocoronary saphenous vein graft aneurysm presenting with unstable angina pectoris.We report the case of a 60-year-old man with a history of coronary bypass surgery 20 years prior who had a fever, chest pain, and a mediastinal mass develop after a complicated postoperative course of abdominal aortic aneurysm resection. A mycotic aneurysm of the saphenous vein graft to his left anterior descending coronary artery was diagnosed based on blood culture results and visualization of the aneurysm before resection. A summary of the saphenous vein graft aneurysm and pseudoaneurysm cause, diagnosis, and management is detailed.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm (Clic here for more details about this article) |
6/21. hepatic artery pseudoaneurysm - duodenal fistula after living donor liver transplant.A 38-yr-old woman who underwent living donor liver transplant for alcoholic cirrhosis presented 2 months after transplant with gastrointestinal bleeding from an hepatic artery pseudoaneurysm eroding into the duodenum. She underwent endovascular hepatic artery stenting, resulting in cessation of hemorrhage and salvage of the graft.- - - - - - - - - - ranking = 5keywords = pseudoaneurysm (Clic here for more details about this article) |
7/21. Combined endovascular stent grafting and endoscopic injection of fibrin sealant for aortoenteric fistula complicating esophagectomy.A 67-year-old man with previous total gastrectomy and roux-en-Y esophagojejunostomy had hematemesis 4 weeks after esophagectomy performed because of carcinoma of the esophagus. Investigation showed an aortojejunal fistula with a thoracic aortic pseudoaneurysm. Endovascular stent grafting of the pseudoaneurysm, followed by endoscopic injection of fibrin sealant for the fistula, was performed, and the infection was controlled with broad-spectrum antibiotic agents together with drainage and daily irrigation of the pseudoaneurysm sac. The fistula subsequently healed. The patient remained well 14 months after the procedure; follow-up computed tomograms at 12 months did not show any pseudoaneurysm, and there was no evidence of reopening of the fistula.- - - - - - - - - - ranking = 4keywords = pseudoaneurysm (Clic here for more details about this article) |
8/21. Primary aortoduodenal fistula due to septic aortitis.We report the second case of a primary aortoenteric fistula resulting from septic aortitis with a contained aortic leak into the retroperitoneum and finally erosion into the duodenum. An emergency laparotomy revealed a fistula between the third part of the duodenum and a decompressed sac (false aneurysm) arising from a nonaneurysmal, grossly infected pararenal aorta. The purpose of this report is to present this rare case in detail and to review primary aortoenteric fistulas reported in the English language literature. Most fistulas form in association with an abdominal aortic aneurysm and rarely are due to infection. Only 6% of patients presented with the classic triad of abdominal pain, a palpable mass, and gastrointestinal bleeding. Although 29% of patients presented with massive hemorrhage, adequate time usually existed for surgical treatment of these complications. A patient with ill-defined abdominal pain and fever who suddenly develops a palpable abdominal mass should have an emergency ultrasound or CT scan to exclude the possibility of an infected aortic aneurysm or a contained rupture of an infected nonaneurysmal aorta. If the symptoms are associated with bleeding and the patient is hemodynamically stable, emergent endoscopy should also be performed. If a primary aortoenteric fistula or an aortic pseudoaneurysm is confirmed, emergent surgery should be undertaken to avoid rupture into the bowel or retroperitoneum.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm (Clic here for more details about this article) |
9/21. Aortoduodenal fistula following aortobifemoral bypass.A patient with a fistula between the aortic graft and the third portion of the duodenum was admitted in our institution and submitted to surgery that involved extra anatomical axillobifemoral bypass, prosthesis removal and bowel resection with a gastrojejunal Roux anastomosis. A prosthetic fistula after aortic surgery is a rare but potentially fatal complication. Erosion, infection and pseudoaneurysm are mechanisms in the pathogenesis of aortoenteric fistula. Because of the high mortality and morbidity, associated with secondary aortoenteric fistula, surgical treatment is always recommended. A combination of endoscopy and CT or MRI may offer the best chance of detecting a fistula, but the most important tool to achieve diagnosis is clinical suspicion. An aortoenteric fistula should always be suspected in all patients who have undergone aortic graft surgery and present with gastrointestinal haemorrhage. The authors discuss the modern management of this challenging complication of aortic surgery.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm (Clic here for more details about this article) |
10/21. Salmonella reinfection manifesting as a fistula between the duodenum and an aortic stump pseudoaneurysm.Despite the worldwide increase in salmonella infections, a Salmonella infection of an aortic graft is an exceptional event. A Salmonella reinfection manifesting as a fistula between the duodenum and an aortic stump pseudoaneurysm 30 months after prosthetic excision, aortic ligature and extra-anatomic bypass for a Salmonella graft infection is a unique event. This unusual late complication described in this case report developed in 1 of the 5 patients whose Salmonella aortic graft infections have been previously reported. The reinfection causing septic aortitis responded to conventional surgery.- - - - - - - - - - ranking = 5keywords = pseudoaneurysm (Clic here for more details about this article) |
