1/48. Post-traumatic pancreatitis with associated aneurysm of the splenic artery: report of 2 cases and review of the literature.In patients with acute pancreatitis, profuse gastrointestinal bleeding is associated with a high death rate. The cause of such bleeding must be evaluated and the bleeding controlled urgently. Aneurysm formation is usually the cause of the bleeding. angiography is needed to make a definitive diagnosis and the bleeding site should be controlled by angiographic embolization if possible. If this fails, aneurysm resection is necessary. Two patients are described. Both had aneurysms of the splenic artery, presenting as massive gastrointestinal bleeding in one patient and bleeding into an associated pseudocyst in the other. They required surgical repair, which was successful in both cases.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/48. Spontaneous thrombosis of a pseudoaneurysm complicating pancreatitis.patients with a visceral aneurysm are at high risk for acute transpapillary, intra-, or retroperitoneal hemorrhage, necessitating either surgical or endovascular therapy. We report an instance of spontaneous thrombosis of a pseudoaneurysm complicating pancreatitis before endovascular treatment could be performed. causality and the literature of spontaneous thrombosis in pseudoaneurysms are discussed.- - - - - - - - - - ranking = 168.90621281247keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/48. Management of severe acute pancreatitis with a somatostatin analog in a patient undergoing surgery for dissecting thoracic aneurysm: report of a case.A patient who was admitted to our hospital to undergo surgery for a dissecting thoracic aneurysm suffered preoperatively from severe acute pancreatitis with pancreatic pseudocysts. Computerized tomography (CT) demonstrated the presence of new fluid collection around the cyst with the absence of pancreatic necrosis. He was given a somatostatin analog (sandostatin), which was effective in decreasing the abdominal symptoms, leukocyte counts, and the serum C-reactive/protein level. A CT scan revealed that the pancreatic pseudocyst and peripancreatic fluid collection had disappeared. Although somatostatin has been reported to be ineffective for acute pancreatitis with necrosis, pancreatitis without necrosis may regress after treatment with sandostatin. This is probably due to its suppressive effect on the exocrine function, thus resulting in a decrease of pancreatic juice infiltration.- - - - - - - - - - ranking = 0.83333333333333keywords = aneurysm (Clic here for more details about this article) |
4/48. Impersonation of a ruptured thoracic aneurysm by a transdiaphragmatic pancreatic cyst.Pancreatic cysts can, in rare cases, expand into the posterior mediastinum and may require surgical resection. We present the case of a patient with a thoracic aneurysm, in whom the mediastinal involvement of a chronic pancreatic cyst masqueraded as a ruptured aneurysm. Surgery was undertaken: first, the initial resection and drainage of the thoracic portion of the pseudocyst, and second, a thorough cleansing of the entire cyst through median laparotomy 15 days later.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
5/48. Pancreatic pseudoaneurysm converted from pseudocyst: transcatheter embolization and serial CT assessment.We present a case of pancreatic pseudoaneurysm converted from a pseudocyst. Contrast-enhanced CT disclosed a round enhancing lesion at the previously identified pseudocyst, and angiography confirmed the diagnosis of a pseudoaneurysm. The pseudoaneurysm was successfully treated by arterial embolization. We believe arterial embolization to be the treatment of choice for pseudoaneurysm as a complication of pancreatitis.- - - - - - - - - - ranking = 224.98606152774keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
6/48. Complicated chronic pancreatitis causing mycotic aortic aneurysm: in situ replacement with a cryopreserved aortic allograft.Mycotic aortic aneurysm, which resulted from infected pancreatic pseudocysts with retroperitoneal abscess, developed in a patient with chronic pancreatitis. The aorta was approached through median laparotomy. Necrotic material was debrided from the pancreatic pseudocysts, and the mycotic aneurysm was resected. The aorta was replaced in situ with a cryopreserved aortic allograft. This report discusses the rare complication of pancreatic pseudocysts, which affect the infrarenal abdominal aorta and cause a large mycotic aneurysm. This case suggests that the use of cryopreserved allografts is promising for in situ reconstruction, even in a grossly infected field.- - - - - - - - - - ranking = 1.1666666666667keywords = aneurysm (Clic here for more details about this article) |
7/48. Hemorrhagic pseudocyst and pseudocyst with pseudoaneurysm successfully treated by pancreatectomy: report of three cases.Hemorrhagic pseudoaneurysm of pancreatic pseudocyst is one of the serious complications of acute pancreatitis. We successfully treated three patients who had hemorrhagic pseudocyst and pseudocyst with pseudoaneurysm by pancreatectomy. Case 1 was 43-year-old Japanese man who had had several episodes of acute pancreatitis and was diagnosed with hemorrhagic pseudoaneurysm of the splenic artery in a pseudocyst in the pancreatic tail, shown on computed tomography (CT) and angiography. Transarterial embolization (TAE) yielded hemostasis of the pseudoaneurysm, but rebleeding occurred 2 weeks after the TAE. Distal pancreatectomy and splenectomy was successfully performed. Case 2 was a 64-year-old Japanese man who presented to us with several attacks of acute pancreatitis. Imagings showed bleeding pseudoaneurysm of the transverse pancreatic artery in a pseudocyst in the pancreatic body. Because of marked stenosis in the proximal portion of the transverse pancreatic artery, TAE was unsuccessful. Distal pancreatectomy and splenectomy was performed successfully. Case 3 was a 40-year-old Japanese woman who had a history of abdominal trauma. Imagings showed bleeding pseudoaneurysm of the splenic artery in a posttraumatic pseudocyst in the pancreas. TAE of the pseudoaneurysm was unsuccessful because of the proximity of the pseudoaneurysm and the splenic artery. Distal pancreatectomy and splenectomy was successfully performed and her postoperative outcome was satisfactory. Whenever interventional radiology (IVR) is not indicated or has failed, aggressive and immediate surgical intervention should be considered for early and definitive recovery in these patients.- - - - - - - - - - ranking = 337.47909229161keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
8/48. Superior mesenteric artery pseudoaneurysm successfully treated with polytetrafluoroethylene covered stent.A postoperative superior mesenteric artery pseudoaneurysm that communicates with a pancreatic pseudocyst after aortic surgery is a difficult management problem. Untreated, this condition can lead to exsanguination. Traditional surgical treatment has many potential complications. Endovascular repair has the potential for avoidance of surgical complications. We present the first superior mesenteric artery pseudoaneurysm successfully treated with A polytetrafluorethylene covered stent.- - - - - - - - - - ranking = 168.7395461458keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/48. Haemosuccus pancreaticus: treatment by arterial embolization.AIM: Haemosuccus pancreaticus is bleeding into the pancreatic duct from a peripancreatic artery. This condition most commonly follows pseudoaneurysm formation secondary to acute or chronic pancreatitis. It is a rare disorder, challenging in both diagnosis and therapy. We present an eight-year experience of managing these patients using endovascular embolization as the primary therapy. MATERIALS AND methods: We retrospectively reviewed the imaging, laboratory results and clinical notes of the five patients who presented to this institution between 1991-1999 with gastrointestinal bleeding subsequently found to be haemosuccus pancreaticus. RESULTS: There were four men and one women aged 38-75 years. All had a history of gastrointestinal haemorrhage and had acute (n=1) or chronic pancreatitis with a complicating pseudoaneurysm. All underwent embolization as the primary therapy for the pseudoaneurysm. There was immediate technical success in all cases without major complication. No patient required operative surgery for the pseudoaneurysm. Follow-up ranged from 18 months to 7 years. One patient died four years after embolization due to hepatic failure but the other four remain well without further gastrointestinal bleeding. CONCLUSION: Endovascular embolization is an effective and safe treatment for haemosuccus pancreaticus.- - - - - - - - - - ranking = 112.49303076387keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
