Doppler Ultrasound Findings in the Hepatic Artery Shortly

Variation in hepatic arterial anatomy is seen in 40-45% of people. Classic branching of the common hepatic artery from the celiac artery, and the proper hepatic artery into right and left hepatic arteries to supply the entire liver, is seen in only 55-60%. A single or double cystic artery may arise off the proper hepatic artery Hepatic artery flow is in the same direction as the portal vein (hepatopetal). The hepatic artery normally demonstrates a low-resistance waveform with continuous forward flow throughout the car-diac cycle (Fig. 6). The hepatic veins (HVs) drain blood from the liver into the inferior vena cava. The normal Doppler waveform obtained from the HVs. SCANNING TECHNIQUE AND NORMAL ANATOMY Duplex ultrasound (DUS) evaluation of the hepatic vasculature is best performed using a 2- to 5-MHz curved array transducer in a fasting (8 to 12 hours) patient Mesenteric Duplex Ultrasound Celiac artery disease - • >70% stenosis PSV > 200 cm/sec • Total / near total occlusion Absent flow Reversed common hepatic artery flow Hepatic artery Note reversed flo A recent adult study found mean peak common hepatic artery velocities of 84 ± 40 cm/s in uncomplicated cases versus 46 ± 27 cm/s in patients with hepatic artery stenosis [ 8 ]. However, that study considered ultrasound at hospital discharge, later than POD1, and velocities tend to decrease as time passes postoperatively

Ultrasound Assessment of the Hepatic Vasculature

While the primary imaging modalities for screening a pre-operative candidate are computed tomography (CT) and magnetic resonance imaging (MRI), Doppler ultrasound is commonly used to evaluate vessel patency and hepatic hemodynamics On ultrasound, a pseudoaneurysm appears as a cystic structure often close to the hepatic hilum or sometimes it can be intrahepatic in location. Color Doppler may show a pulsatile, disorganized arterial flow pattern or characteristic bidirectional flow. CT scan shows an enhancing mass communicating with the hepatic artery or one of its branches The purpose of this study was to compare the diagnostic performance of computed tomography angiography (CTA) and contrast-enhanced ultrasound (CEUS) when used to diagnose significant hepatic artery occlusion (HAO) in patients that was suspected on Doppler ultrasound (US).

Literature for normal measurements of hepatic vein and hepatic artery in children is lacking. In this study, the investigators aim to conduct a prospective, cross-section observational study to establish the normal measurements ranges of hepatic vein, hepatic artery and portal vein in healthy children in the investigators' locality blood flow velocities and waveforms can permit inferences to be made about liver and system pathophysiology even in native livers. This review will illustrate that hepatic parenchymal abnormalities, as well as primary vascular abnormalities both upstream and downstream of the proper hepatic artery, can be inferred from careful interrogation of its Doppler signature during routine abdominal.

Hepatic artery stenosis is a common vascular complication following liver transplant. • Doppler ultrasound is non-invasive to monitor for hepatic artery stenosis. • Intrahepatic artery resistive index is excellent discriminator for stenosis. • Intrahepatic artery systolic acceleration time is good discriminator for stenosis. Eighty‐nine did not have a replaced hepatic artery and the ultrasound assessment was falsely positive in four of them (specificity 96%). Two of the four false negative results could be explained by a stenosis of the superior mesenteric artery in front of the origin of the replaced hepatic artery The aim of this work is to evaluate the role of Ultrasound-Doppler in the hemodynamic study of hepatic vessels during the liver cirrhosis in Togo.
