OBJECTIVE Our purpose was to test the hypothesis that the HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome is the result of excessive vasoconstriction of the hepatic arterial circulation. STUDY DESIGN Doppler ultrasonography was used to measure the pulsatility index of the common hepatic artery in 14 women with preeclampsia, 15 with preeclampsia complicated by HELLP syndr...

It should be expected that the hepatic blood flow increase in the cases with liver metastasis. We aimed to find out if there is a correlation between Doppler parameters and hepatic metabolic activity in oncology patients. 35 patients with hepatic metastases who were identified by 18F-fluorodeoxyglucose positron emission tomography scan and assessed with Doppler ultrasound were included in this ...

Aim: The aim of this prospective study was to determine and compare the various parameters and indices of portal vein, hepatic artery and splenic artery by sonographic Doppler imaging in chronic hepatitis C patients and healthy individuals.Methods: 45 Chronic Hepatitis C patients and 90 Healthy adults formed two groups. All participants underwent color Doppler imaging of the portal vein, hepati...

Portal hypertension is one of the most frequent complications of Background: cirrhosis. β-adrenergic blockers, with or without organic nitrates, are currently used as hypotensive agents. Statins such as simvastatin seem to be safe for patients with chronic liver diseases and exert multiple pleiotropic actions. This study aimed to assess PTH using Doppler ultrasound in patients with cirrhosis be...

INTRODUCTION The compensatory increase in hepatic arterial flow with a decrease in portal venous flow is known as the hepatic arterial buffer response. In cirrhosis with elevated portal pressure, the vascular resistance of the hepatic artery is decreased. Whether this lower resistance of the hepatic artery is a consequence of portal hypertension or not remains unknown. STUDY AIM The aim of th...

Background Fetal growth restriction is the second leading cause of perinatal morbidity and mortality. The incidence of intrauterine growth restriction (IUGR) is estimated to be approximately 5 percent in the general obstetric population. Abnormal uterine artery suggest a maternal cause for the growth restriction where as normal uterine artery Doppler studies suggest that a fetal cause. Use of u...

background endothelial injury is a well-known complication in chronic kidney disease (ckd) and hemodialysis. one of the sites in which early vascular changes may be detected is the retina. of course, these flow changes may not be detected in ophthalmologic exams, but it seems that color doppler sonography of retinal arteries may be helpful in these cases. objectives in previous studies on ckd p...

background the identification of the dorsal sector of the liver and its detailed vascular anatomy is of primary importance for surgical practice and segmental transcatheter arterial chemoembolization. objectives this study aimed to investigate the feeding arteries of tumors in dorsal sector of the liver. patients and methods computed tomography (ct) and digital subtraction angiography (dsa) ima...
