1/13. Successful treatment of a pseudoaneurysm of the cystic artery with microcoil embolization.Pseudoaneurysms of visceral arteries are uncommon but well-characterized vascular abnormalities, usually provoked by intraabdominal inflammatory processes such as pancreatitis or cholecystitis, or by surgical trauma. However, pseudoaneurysms of the cystic artery are rare. They complicate cholecystitis or cholecystectomy, and manifest as hemobilia as they rupture into the biliary tree. The advent of transcatheter embolization techniques has begun to allow minimally invasive treatment of these life-threatening complications. Transcatheter embolization can be performed using several types of material, such as synthetic occlusive emulsions, gelatin sponges or other particles, or metallic microcoils. Microcoils are small metallic helical particles, made of stainless-steel, platinum, or tungsten. Super-selective catheterization of an artery and release of microcoils causes the vessel to thrombose and allows control of bleeding.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/13. Acute cholecystitis secondary to hemobilia.Invasive diagnostic and therapeutic techniques such as percutaneous transhepatic cholangiography, endoscopic retrograde cholangiopancreatography (ERCP), transjugular intrahepatic portosystemic shunting, and laparoscopic cholecystectomy have led to a rise in hemobilia. Most complications from hemobilia are attributable to acute blood loss; other complications are secondary to thrombus formation in the biliary tree. We present a case report of acute cholecystitis secondary to hemobilia after percutaneous liver biopsy. The role of ERCP in the diagnosis and treatment of this exceedingly rare event is discussed.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/13. Acute pancreatitis with hemobilia following percutaneous liver biopsy.hemobilia following liver biopsy is rare and acute pancreatitis associated with hemobilia in such a situation is rarer. We report a 55-year-old man with ulcerative colitis and hepatitis c-positive liver disease who developed acute pancreatitis following liver biopsy. Surgical removal of blood clots from the biliary tree led to recovery.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/13. Potentially fatal haemobilia due to inappropriate use of an expanding biliary stent.AIM: To highlight the fatal complication caused by expanding biliary stents and the importance of avoiding use of expanding stent in potentially curable diseases. methods: Arteriobiliary fistula is an uncommon cause of haemobilia. We describe a case of right hepatic artery pseudoaneurysm causing arteriobiliary fistula and presenting as severe malena and cholangitis, in a patient with a mesh metal biliary stent. The patient had lymphoma causing bile duct obstruction. RESULTS: Gastroduodenoscopy failed to establish the exact source of bleeding and hepatic artery angiography and selective embolisation of the pseudo aneurysm successfully controlled the bleeding. CONCLUSION: Bleeding from the pseudo aneurysm of the hepatic artery can be fatal. Mesh metal stents in biliary tree can cause this complication as demonstrated in this case. So mesh metal stent insertion should be avoided in potentially benign or in curable conditions. Difficulty in diagnosis and management is discussed along with the review of the literature.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
5/13. life-threatening hemobilia caused by hepatic artery pseudoaneurysm: a rare complication of chronic cholangitis.hemobilia is one of the causes of obscure gastrointestinal haemorrhage. Most cases of hemobilia are of iatrogenic or traumatic origin. hemobilia caused by a hepatic artery pseudoaneurysm due to ascending cholangitis is very rare and its mechanism is unclear. We report a 74-year-old woman with a history of surgery for choledocholithiasis 30 years ago, suffering from a protracted course of life-threatening gastrointestinal bleeding. A small intestines series and endoscopic retrograde cholangiopancreatography revealed a chronic cholangitis with marked contrast reflux into the biliary tree. Angiography confirmed the bleeding from a pseudoaneurysm of the middle hepatic artery. Coil embolization achieved successful hemostasis. We discussed the mechanism and reviewed the literature.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/13. Iatrogenic haemobilia: ultrasound appearance of intragallbladder haemorrhage. A report of two cases.Ultrasound appearance of intragallbladder haemorrhage in two patients with haemobilia is presented. gallbladder lumina were occupied by non-shadowing, firm masses of mixed echogenicity representing blood clots. In both cases iatrogenic trauma following percutaneous transcholecystic cholangiography and blind hepatic biopsy caused bleeding in the biliary tree.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/13. cholangitis, hemobilia, and cholangiocarcinoma. Management of a fistula between an obstructed right hepatic duct and the portal vein.cholangitis is the most common cause of sepsis in patients with obstructing carcinomas of the biliary tree. Catheter and stent placement may relieve or exacerbate the septic course. Transhepatic stent placement produced a cholangioportal fistula and hemobilia in a patient with cholangiocarcinoma. The described technique of retrograde operative decompression and clot evacuation may be used in patients in whom portal dissection is hazardous or in whom preservation of an existing cholangiojejunostomy in the portal region is desired.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
8/13. Sonographic findings in traumatic hemobilia: report of two cases and review of the literature.hemobilia consists of an arteriobiliary fistula, usually due to central liver rupture with bleeding into the biliary tree. It is due to trauma in over 50% of cases, with an increasing incidence of iatrogenically caused hemobilia. The sonographic findings in two cases of traumatic hemobilia are presented and the literature is reviewed. These findings include clot within the gallbladder and the extrahepatic ducts, liver hematoma, and aneurysm of the hepatic artery.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
9/13. hemobilia from ruptured hepatic artery aneurysm: angiographic demonstration of arteriobiliary fistula in a successfully treated case.rupture of a hepatic artery aneurysm into the biliary tree is a rare cause of hemobilia. The dramatic nature of the disease and the difficulties in obtaining a preoperative diagnosis are the main causes of its high mortality rate. Progress in vascular radiology and surgery seems to be an important factor in improving the survival rates in patients with this type of hemobilia. A case of a patient with an aneurysm of the common hepatic artery ruptured into the common bile duct is reported. Preoperative arteriography revealed the aneurysm and the arteriobiliary fistula causing massive hemobilia. The patient was successfully treated by arterial ligation and is symptom free after 2 years.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/13. Hepatobiliary scanning in hemobilia-induced acute cholecystitis.Radionuclide scanning of the hepatobiliary tree is highly accurate for the detection of patients with acute cholecystitis. hemobilia, a rare complication of percutaneous liver biopsy, may result in blood clots within the biliary canaliculi. Such clots, like gallstones, may occlude the ducts and produce a clinical syndrome indistinguishable from acute cholecystitis. A patient with acute cholecystitis resulting from hemobilia following percutaneous biopsy of the liver is described. The diagnosis of acute cholecystitis secondary to blood clots was made with technetium 99mTc Iprofenin (Pipida [Sn]) scintigraphy. The patient was treated conservatively, and follow-up Pipida scan 6 weeks later demonstrated normal hepatobiliary function.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
