HANSON, KENNETH M., AND PAUL C. JOHNSON. 4kzzl control of hepatic arterial and portal uenous jaw in the dog. Am. J. Physiol. 211(3): 712-720. I g66.-Hemodynamic studies were made in over IOO experiments on the denervated, autoperfused, dog liver in situ. Electromagnetic flowmeters were used. Data\ are given on pressure-flow relationships in both vascular circuits, with and without simultaneous ...

hepatic artery aneurysms are rare but potentially life threatening. we describe a novel case of a successful endovascular coil embolization of a huge hepatic artery aneurysm. a 67-year-old woman presented with recent abdominal pain that had begun from 2 weeks before referring to our hospital. sonographic and computerized tomographic (ct) findings revealed a huge hepatic artery aneurysm with 95 ...

UNLABELLED Laparoscopic surgery is associated with systemic and splanchnic hemodynamic alterations. Recent data suggest that small-dose dobutamine may attenuate the reduction in splanchnic blood flow associated with increments in intraabdominal pressure. We conducted this study to analyze the effects of dopamine and dobutamine on the hepatic circulation in this setting. Twenty-one pigs were ane...

BACKGROUND/AIMS Clinical validation is required to determine whether Doppler measurements are comparable before and after administering ultrasound contrast agent (USCA). The purpose of this study is to explore whether the use of USCA affects spectral Doppler analysis in recipients of liver transplantation (LT). METHODS For this study, 36 patients were examined using Doppler ultrasonography (U...

Hepatic artery aneurysms are a rare cause of upper gastrointestinal hemorrhage and may represent significant problems in both diagnosis and management. We report a 70 year old patient with gastrointestinal bleeding from a fistula between a 7 cm hepatic artery aneurysm and the duodenum. He underwent successful surgical management with endoaneurysmorrhaphy and duodenal wall repair.

Hepatic artery pseudoaneurysm is a rare complication of laparoscopic cholecystectomy. A high index of suspicion and early identification and therapy are important points needed to prevent rupture. We report a case of complex biliary and vascular injuries 4 weeks after a laparoscopic cholecystectomy. The patient had recurrent bleeding from a hepatic artery pseudoaneurysm that has been treated su...
