1/41. Spontaneous cervical hematoma: a report of two cases.Cervical hematomas are generally associated with trauma, surgery, and tumors. Although they are rare, they can be life-threatening because they put the patient at risk for great-vessel compression and upper airway obstruction. We describe two cases of spontaneous cervical hematoma--one in an 81-year-old man and the other in a 30-year-old woman. The man reported dysphonia, dysphagia, and neck swelling of 5 hours' duration. He had been taking 100 mg/day of aspirin for a cardiovascular condition. Examination revealed that the man had polycythemia vera. The woman was found to have neck ache, odynophagia, and cervical ecchymosis; portal hypertension, schistosomiasis, and blood dyscrasia were also found. Both patients denied trauma. A suspected diagnosis of cervical hematoma was confirmed by computed tomography, and treatment was instituted. The hematomas resolved in about 2 weeks. The treatment of cervical hematoma is controversial, although it is agreed that the evaluation of upper airway obstruction and its permeability is mandatory. Surgical treatment is generally reserved for complicated cases because of the risk of infection or bleeding.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/41. Segmental portal hypertension due to a splenic echinococcus cyst.A 60-year-old Libyan woman developed perihilar splenic varices without other signs of portal hypertension. Plain abdominal X-ray examination showed two calcified structures in the left and right hypochondria. Ultrasound examination disclosed a 3-cm diameter, globally calcified hydatid cyst lodged in a critical location at the hilar region of the spleen. The cyst was compressing the hilar vessels which resulted in dilatation and varix formation. Another hydatid cyst measuring 5 cm in diameter, with extensive wall calcification was visualized in the right lobe of the liver. The splenic size was within normal limits. The liver revealed normal texture and size and the portal vein was of normal caliber. The patient underwent an uneventful splenectomy and was well at discharge.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/41. Idiopathic portal hypertension associated with systemic lupus erythematosus.A case of idiopathic portal hypertension (IPH) associated with systemic lupus erythematosus (SLE) is reported in a 38-year-old man who had been diagnosed with SLE and treated for 18 years. Esophageal varices. found in 1994 on endoscopic examination, had been followed up for 2 years. On July 16, 1996, he was admitted to Nagoya University Hospital because there was a high risk of bleeding from the esophageal varices due to severe thrombocytopenia. As partial splenic embolization had temporarily controlled the thrombocytopenia, splenectomy and devascularization of the stomach vessels were performed after endoscopic ligation of the esophageal varices. Histological specimens of wedge biopsied liver showed chronic inactive hepatitis without cirrhosis. The presence of anticardiolipin antibody, indicated by positivity for lupus anticoagulant, was suggestive of the presence of a common immunological mechanism in the etiology of SLE and IPH.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/41. Splenic vascular malformations and portal hypertension in hereditary hemorrhagic telangiectasia: sonographic findings.Hereditary hemorrhagic telangiectasia, or Osler-Rendu-Weber disease, is an autosomal dominant disorder in which a variety of vascular dysplasias occur throughout the organ systems. We report the gray-scale and color Doppler sonographic findings in a case of hereditary hemorrhagic telangiectasia. Gray-scale sonographic examination revealed massive splenomegaly, multiple dilated intrasplenic vascular structures (some with adjacent punctate calcifications), an aneurysmal dilatation of the splenic vein, dilated intrahepatic portal branches, and marked atrophy of the right hepatic lobe. color Doppler sonography showed dilatation of the truncus coeliacus and high-velocity flow in the splenic artery. There were significant aliasing in the splenic hilum and an abnormal, arterialized flow in intrasplenic branches of the splenic vein. The splenic vein was massively enlarged with increased flow velocity and contained an isolated aneurysmal dilatation in the hilum. There were multiple serpiginous retroperitoneal collateral vessels, and the left gastric vein was dilated with hepatofugal flow. The patient had portal hypertension that developed secondary to the increased portal flow.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/41. Portopulmonary hypertension syndrome in schistosomiasis mansoni.Portopulmonary hypertension syndrome (PPHS) is a complication of portal hypertension where the substrate is micro-vessel lesions which are indicative of plexogenic arteriopathy. PPHS has not been linked to pulmonary schistosomiasis. We report, to the best of our knowledge for the first time, a case of PPHS associated with schistosomiasis mansoni.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/41. pancreaticoduodenectomy in portal hypertension: use of the Ligasure.BACKGROUND/PURPOSE: The Ligasure Vessel Sealing System (LVSS) is a new bipolar device, put on the market in 1999, which provides safe and quick hemostasis, sealing blood vessels up to 7 mm in diameter or tissue bundles without dissection or isolation. We tested this instrument in a patient with portal hypertension who had to be submitted to a complex abdominal procedure. methods: A male patient (aged 57 years) with well-compensated cirrhosis of the liver, related to hepatitis c virus (HCV) (child A) was diagnosed with a neoplasm of the pancreatic head. We performed a Whipple pancreaticoduodenectomy and hemostasis was almost entirely performed with the LVSS. All the blood vessels up to 7 mm in diameter were sealed in this way. Larger vessels were suture ligated primarily. RESULTS: No post-application bleeding was seen. No postoperative hemorrhagic complications occurred. A significant reduction in blood loss and in surgical time was noted. CONCLUSIONS; We believe that the LVSS could be extremely useful in all the fields of hepatopancreatobiliary surgery, especially in patients with portal hypertension with large intestinal and omental varices. The LVSS guarantees excellent hemostasis, reducing the risk of serious blood loss and shortening the time of surgery, so improving the prognosis.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
7/41. Hypoplasia of the right hepatic lobe associated with portal hypertension and idiopathic retroperitoneal fibrosis.A 22-year-old man was referred to our hospital because of thrombocytopenia. Abdominal computed tomography (CT) revealed hypoplasia of the right hepatic lobe, the development of porto-systemic collateral vessels, splenomegaly and a periaortic soft-tissue mass. Laboratory tests and needle liver biopsy indicated no evidence of liver cirrhosis. Consequently, a diagnosis of hypoplasia of the right hepatic lobe associated with portal hypertension and idiopathic retroperitoneal fibrosis was established. Portal hypertension and hypersplenism was thought to be the cause of the thrombocytopenia. CT arterioportography revealed that anomalies of the portal venous system could have resulted in the hypoplasia of the right hepatic lobe. This is the first report describing hypoplasia of the right hepatic lobe accompanied by supervening idiopathic retroperitoneal fibrosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/41. Neonatal candida albicans septic thrombosis of the portal vein followed by cavernous transformation of the vessel.We report two premature neonates with candida albicans septic thrombosis of the portal vein who developed, in very early childhood, the sonographic appearance of cavernous transformation of the vessel and/or clinical signs of extrahepatic portal hypertension.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
9/41. Portal hypertensive hemorrhage from a left gastroepiploic vein caput medusa in an adhesed umbilical hernia.Caput medusa is a frequent incidental finding in patients with portal hypertension that usually represents paraumbilical vein portosystemic collateral vessels draining into body wall systemic veins. A symptomatic caput medusa was seen in a morbidly obese patient after an umbilical hernia repair, which was fed not by the left portal vein but by the left gastroepiploic vein, in a recurrent adhesed umbilical hernia that likely contained herniated omentum. Refractory hemorrhage from this caput medusa was successfully treated by transjugular intrahepatic portosystemic shunt creation and balloon-occluded variceal sclerosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/41. Berry splenic artery aneurysm rupture in association with segmental arterial mediolysis and portal hypertension.A rare case of berry splenic artery aneurysm (SAA) rupture associated with segmental arterial mediolysis (SAM) and portal hypertension is reported. A 66-year-old woman, diagnosed as having liver cirrhosis and portal hypertension 6 years earlier, suddenly developed a lancinating pain in the upper abdomen and lost consciousness. She recovered consciousness while being transferred to hospital by ambulance. During the investigations, her level of consciousness suddenly deteriorated. ultrasonography showed a massive intraperitoneal hemorrhage, and she died 5(1/2) h after admission. On gross examination at autopsy it was not possible to find the rupture point of the vessel because the pancreas was embedded in a massive hematoma. However, careful dissection of the pancreatic tail after fixation revealed a berry aneurysm measuring 0.8 cm in diameter in a branch adjacent to the bifurcation in the distal third of the main splenic artery. Microscopic examination detected a rupture of the aneurysm. The histology of the arterial wall proximal to the aneurysm showed typical SAM. In general, berry SAA caused by SAM is rare and unlikely to rupture. The SAA in the present case likely occurred and ruptured due to the combination of SAM and portal hypertension.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
