INTRODUCTION Percutaneous transhepatic portal embolization is often performed to expand the indications for hepatic resection. Various etiologies of hepatic artery pseudoaneurysm have been reported, but regardless of the etiology, hepatic artery pseudoaneurysm is usually managed with an endovascular approach or open surgery, depending on the location and clinical symptomatology. However, it is ...

BACKGROUND There are few reports regarding the changes within the vessels in the initial stage of type 2 diabetes. The aim of this study was to estimate the hemodynamic and morphological parameters in foot arteries in type 2 diabetes subjects and to compare these parameters to those obtained in a control group of healthy volunteers. MATERIAL/METHODS Ultrasound B-mode, color Doppler and pulse ...

Performing resection of a biliary tract malignancy with a hepatic artery aneurysm is very challenging. Resection of the extrahepatic bile duct and extra-anatomical reconstruction can be successfully performed using free radial artery autografts from the aorta to the right hepatic artery. Hepatic artery thrombosis can be prevented with intimal preservation.

CCIDENTAL INTERRUPTION of the hepatic A artery or one of its branches is a feared surgicaI compIication. AIthough vascuIar repair may be feasibIe, the in jury is frequentIy so extensive that arteriaI reconstruction is not possibIe. In this situation, accurate knowIedge of the consequences of Iigation of the hepatic artery wouId be desirabIe. In the dog and other experimentaI animaIs, hepatic ar...

The pathophysiological role of an increase in circulating vasopressin in sustaining global and regional vasoconstriction in patients with congestive heart failure has not been established, particularly in patients with hyponatraemia. To assess this further, 20 patients with congestive heart failure refractory to digoxin and diuretics were studied before and 60 minutes after the intravenous inje...

OBJECTIVE It was the goal of this study to compare endothelium-dependent and endothelium-independent flow reserve in vascular regions supplied by the left internal mammary artery before and after bypass graft surgery. METHODS The native internal mammary artery in situ was investigated in 13 patients (age 61.8 +/- 8.0 years) with angiographically proven coronary artery disease. The internal ma...

The authors implied that the abnormal uterine artery Doppler velocimetry is one of the risk markers for preeclampsia in the second or third trimester and that its abnormality is practically defined at 22–24 weeks as bilateral notching with mean resistance index (RI) > 0.55 (i.e., > 50th centile), unilateral notching with mean RI > 0.65 (> 90th centile), or no notching with mean RI > 0.70 (> 95t...

The effects of angiotensin I (0.2-3.2 ju.g) and angioteasin II (0.1-1.6 fig) injections into the pump-perfused arterial supply of the liver were studied in dogs anesthetized with sodium pentobarbital. Marked increases in hepatic artery perfusion pressure (10—50%), reflecting directicnally similar changes in resistance to blood flow, were caused by either angiotensin I or angiotensin II. Resista...

The hepatic artery aneurysms are rare, especially in interahepatic branches. The frequency consists of 75-80% extrahepatic and 20-25% intrahepatic. Catheterization is achieved usually from common femoral artery, other methods implemented in the case of unsuccessful catheterization from femoral artery, are translumbar and brachial catheterization.The study consist of 565 patients that were refer...
