2024年4月20日 · Vasculature. The liver has a unique dual blood supply: Hepatic artery proper (25%) – supplies the non-parenchymal structures of the liver with arterial blood. It is derived from the coeliac trunk. Hepatic portal vein (75%) – supplies the liver with partially deoxygenated blood, carrying nutrients absorbed from the small intestine. This is ...
Liver: Blood supply, innervation and anatomy - Kenhub
2023年10月30日 · The blood supply of the liver is delivered through the portal vein and the hepatic artery. The hepatic artery brings oxygenated blood to the hepatic tissues, while the portal vein collects the deoxygenated blood from the abdominal contents and filters it.
Liver Anatomy - PMC - PubMed Central (PMC)
HEPATIC VASCULATURE. The liver is a very vascular organ and at rest receives up to 25% of total cardiac output, more than any other organ. Its dual blood supply is uniquely divided between the hepatic artery, which contributes 25% to 30% of the blood supply, and the portal vein, which is responsible for the remaining 70% to 75%.
Hepatic Vasculature: A Conceptual Review - Gastroenterology
The hepatic circulation is reviewed with emphasis on the role of hepatic blood vessels in hepatic and homeostatic functions. Contrasts are made with resistance, capacitance, and fluid exchange functions in other better known vascular beds. Hemodynamic changes that produce shifts in fluid exchange in other tissues are without effect in the liver.
The liver, a functionalized vascular structure - PMC
As indicated by precise anatomy analysis of the liver architecture 19–22, the hepatic artery, portal vein and hepatic vein networks are three-dimensional, highly nested, forming an extremely compact structure.
Analyzing the human liver vascular architecture by combining …
Keywords: 3D reconstruction, hepatic vasculature, image processing, morphology, tree analysis. Introduction. The liver is a fascinating but complex multifunctional organ, characterized by its intricate vascular architecture. Compared with other organs, the liver's vasculature is unique due to the two blood supplies.
The liver, a functionalized vascular structure | Scientific Reports
2020年10月1日 · The hepatic artery, portal vein and hepatic vein form a compact three-dimensional dendritic architecture within the liver. Each tree architecture is composed of a main trunk subdivided into...
Liver vascular anatomy: a refresher | Abdominal Radiology
2018年4月25日 · Non-invasive detailed demonstration of the hepatic vascular anatomy is possible with advanced multi-detector computed tomography (CT) and magnetic resonance (MR) imaging. The objective of this review is to provide a brief overview of clinically relevant hepatic vascular anatomy and important variants.
Assessment of vascular and biliary anatomy and presence of anatomic variants may be important for interventional or surgical planning. Evaluation of hepatic volume can be helpful in estimating functional liver reserve, selecting an appropriate treatment, and determining the prognosis.
Understanding the anatomy of individual arterial branches and hepatic segments is critical for selecting the correct embolization technique for treatment and to avoid complications. The authors describe the morphologic characteristics of hepatic arterial branches (and their mimickers) and hepatic segments on conventional angiograms.
