1/11. Intractable oesophageal variceal bleeding caused by splenic arteriovenous fistula: treatment by transcatheter arterial embolization.We describe a rare case of splenic arteriovenous fistula and venous aneurysm which developed after splenectomy in a 40-year-old woman who presented with epigastralgia, watery diarrhoea, repeated haematemesis and melaena caused by hyperkinetic status of the portal system and bleeding of oesophageal varices. It was diagnosed by computed tomography and angiography, and obliterated with giant Gianturco steel coils.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/11. Repair of secondary aortoesophageal fistula by endoluminal stent-grafting.PURPOSE: To describe a case of secondary aortoesophageal fistula that was treated with an endoluminal stent-graft. CASE REPORT: A 58-year-old woman presented with hematemesis and melena. In 1974 she had an interposition graft repair of an aortic transection sustained during a traffic accident. At the examination in 1998, angiography demonstrated a mechanical disruption of the proximal anastomosis forming an aortoesophageal fistula. A 28-mm x 3.75-cm AneuRx stent-graft was introduced via a right femoral arteriotomy and deployed across the defect. Follow-up CT scans at 18 months showed exclusion of the false aneurysm with no evidence of infection; the patient remains well at >2 years after stent-graft implantation. CONCLUSIONS: Endoluminal repair can be successful in achieving a satisfactory midterm outcome in cases of secondary aortoesophageal fistula.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
3/11. Severe erosion of lumbar vertebral body because of abdominal aortic false aneurysm: report of two cases.STUDY DESIGN: Two cases of lumbar vertebral erosion resulting from abdominal aortic false aneurysm are reported. OBJECTIVE: To present an uncommon complication of aortic endoprosthesis causing spinal pathology. SUMMARY OF BACKGROUND DATA: Vertebral body pathologies usually are associated with fracture, osteoporotic collapse, tumor, spondylitis, or spondylodiscitis. Aortic abdominal aneurysm rarely has been reported as causing lytic lesions of the spine. methods: A retrospective case analysis was performed for two patients with an aorta bifurcation prosthesis and lytic lesions of the spine. False aneurysms were detected at the proximal junction of the prostheses. A biopsy of the affected vertebrae showed no infection or malignancy. Surgery was performed in both cases, and the prostheses were successfully revised. In one case, an anteroposterior spinal fusion was performed because of severe anterior bone loss. RESULTS: The back pain of both patients resolved completely after surgery. In one of the patients, an embolectomy in the right leg failed, and a below-the-knee amputation had to be performed. CONCLUSIONS: In patients with endovascular prostheses, false aneurysm should be considered when lytic lesions of vertebral bodies are differentially diagnosed because these patients can present with only spinal symptoms.- - - - - - - - - - ranking = 8keywords = aneurysm (Clic here for more details about this article) |
4/11. Combined diagnostic and therapeutic imaging of hemosuccus pancreaticus.The justification of a request of ERCP in a patient with hematobilia, was evaluated, based on the medical history and negative endoscopy findings for gastrocolic bleeding. The diagnostic examination was performed: it confirmed the release of blood from the papilla of Vater, however the definitive diagnosis could not be established; CT, as the examination of first choice was performed. It provided additional information and the diagnosis of aneurysm of the splenic vein apparently non communicating with the main pancreatic duct, was established. angiography of the splenic artery was performed as the examination of second choice to definitely ascertain the source of bleeding. During the examination, the aneurysm embolization excluded the affected vessel from the circulation and allowed immediate benefit to the patient.- - - - - - - - - - ranking = 2keywords = aneurysm (Clic here for more details about this article) |
5/11. reperfusion of splanchnic artery aneurysm following transcatheter embolization: treatment with percutaneous thrombin injection.We describe a case of reperfusion of an aneurysm of the pancreaticoduodenal artery following transcatheter coil embolotherapy. The lesion was successfully treated by direct puncture of the aneurysm under computed tomographic guidance, followed by injection of thrombin. This technique is useful when an endovascular approach is not feasible.- - - - - - - - - - ranking = 6keywords = aneurysm (Clic here for more details about this article) |
6/11. Dieulafoy's vascular malformation of the jejunum: first case report of laparoscopic treatment.A case of Dieulafoy's vascular malformation of the jejunum treated by laparoscopic surgery is described. The patient was a 31-year-old-woman who had complained of melena and had severe anemia needing blood transfusion. angiography revealed microaneurysms and hypervascularity of the jejunum in the area between the first and second jejunal arterial fields. Laparoscopic partial resection of the jejunum was performed. The resected specimen was histologically diagnosed as Dieulafoy's vascular malformation. Since the operation, the patient has been free of melena and anemia. Small-intestinal Dieulafoy's vascular malformation is rare, as only 41 cases have been reported during the past three decades. Almost two-thirds of the patients were under 40 years old. Most of the patients complained of melena. The lesion was preoperatively identified in 14 of the 41 patients, while angiography was useful to define the lesion. Thirty-six of 37 patients for whom treatment methods were reported were surgically treated. While there are various treatment methods for intestinal bleeding, a surgical operation is often needed. When the disease location is obvious, treatment with laparoscopic surgery can reliably produce good results, in terms of its rate of cure, minimal invasiveness, and better cosmetic effect.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
7/11. Recurrent hemorrhagic shock from solitary jejunal diverticulum.We report the case of recurrent hemorrhagic shock manifested by massive melena and hematemesis in a 67-year-old patient, previously operated in another hospital for an abdominal aortic aneurysm two weeks before. During hospitalization the red blood cell scintigraphy was positive for bleeding in the jejunum. Intraoperative endoscopy was performed to identify a solitary diverticulum at the proximal jejunum. Approximately 70 cm of the involved segment was resected by an end-to-end anastomosis. Postoperative one-year evolution has been favorable, without any evidence of rebleeding. A review of the literature concerning this disease indicates the rarity of a massive bleeding from solitary jejunal diverticulum and the need to consider this condition in patients with gastrointestinal hemorrhage.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
8/11. Primary aortoduodenal fistula without abdominal aortic aneurysm in association with psoas abscess.Primary aortoenteric fistula (PAEF) is a communication between the aorta and the enteric tract without any previous vascular intervention, e.g., aortic grafting. Although rare, PAEF is a potentially lethal condition that requires a high index of suspicion and prompt surgical intervention. Most of the reported cases involve an abdominal aortic aneurysm. However, in this report, we describe a rare case of a primary aortoduodenal fistula in a nonaneurysmal aorta in association with a psoas abscess, which was treated successfully. At 2-year follow-up, the patient is alive without episodes of bleeding or fever.- - - - - - - - - - ranking = 6keywords = aneurysm (Clic here for more details about this article) |
9/11. Use of a stent graft for bleeding hepatic artery pseudoaneurysm following pancreaticoduodenectomy.Although uncommon, bleeding following pancreaticoduodenectomy is associated with high mortality. Management generally includes surgical reexploration or, alternatively, transarterial embolization. We report the case of a 62-year-old man who presented with massive upper gastrointestinal bleeding 3 weeks after pancreaticoduodenectomy. Selective coeliac angiography revealed a large pseudoaneurysm involving the proper hepatic artery. This was treated successfully with a stent graft. There was no recurrence of bleeding at the 6-month follow-up. To our knowledge, this is the first report of stent graft repair of bleeding hepatic artery pseudoaneurysm following pancreaticoduodenectomy.- - - - - - - - - - ranking = 67.111559988897keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
10/11. A case of melena caused by a hepatic aneurysm ruptured into the intrahepatic bile duct in a patient with allergic granulomatous angiitis.A 46 year old woman was admitted to our institute in June, 1987 with an attack of asthma, as well as remittent fever and leukocytosis accompanied by hypereosinophilia. She was found to have melena from an unknown source upon gastrointestinal examination. Four low-density areas were found in the liver on computed tomography and one of the intrahepatic foci formed a large extrahepatic abscess communicating with the intrahepatic duct on tubography. Resection of the four hepatic segments, including the large abscess, and cholecystectomy were performed. Healed necrotizing arteritis was histopathologically observed in the resected liver specimen, with the four low-density areas on CT scan having all been necrotic foci. One of them formed an intrahepatic biliary fistula and rupture of a hepatic aneurysm into a biliary duct was found to be the cause of melena. Although eosinophil infiltration and extravascular granuloma were not observed, a diagnosis of allergic granulomatous angiitis was made from the characteristic clinical course, systemic vasculitis and peripheral blood eosinophilia. To the best of our knowledge, this is the first report of intrahepatic duct perforation most probably being caused by hepatic aneurysm rupture in a patient with allergic granulomatous angiitis.- - - - - - - - - - ranking = 6keywords = aneurysm (Clic here for more details about this article) |
