Abstract
A corrosion — cast anatomical study was performed on human livers. At first arterio-arterial anastomoses between the inferior phrenic arteries and branches of the main hepatic artery were investigated. Secondly, arterial communications between the right and left hepatic artery are described. 1. The anatomical-functional study of phrenico-hepatic anatomoses gives new detailed information on the arterial blood supply of the liver out of the phrenic arteries. These collaterals are a consistent finding. By far the largest part of the phrenicohepatic anastomoses is derived from the right inferior phrenic artery. The superior and posterior segments receive most of the anastomoses. In about 10 % of our cases we succeeded in filling almost the whole arterial system of the liver by injecting the inferior phrenic arteries. 2. There are three anastomotic pathways from the right hepatic artery to the left: the so-called portal anastomoses (hilar anstomoses), translobar vessels, and the capsular arteries. In korrosionsanatomischen Untersuchungen an menschlichen Lebern wurde geprüft, welche arterio-arteriellen Anastomosen zwischen den Aa. phrenicae inferiores und ästen der A. hepatica propria bestehen. Ferner werden Anastomosen zwischen den Stromgebieten der Aa. hepaticae dextra et sinistra beschrieben. 1. Die anatomisch-funktionelle Untersuchung der phrenico-hepatischen Anastomosen bringt neue detaillierte Aufschlüsse über die arterielle Versorgung des Leberorgans aus den Schlagadern des Zwerchfells. Solche Collateralen existieren regelhaft. Den größten Teil der phrenico-hepatischen Anastomosen liefert die A. phrenica inferior dextra. Die superioren und posterioren Segmente nehmen die meisten Collateralgefäße auf. Bei nahezu 10 % der untersuchten Fälle war über die Collateralen eine Füllung fast des gesamten arteriellen Systems der Leber möglich. 2. Anastomosen zwischen beiden Leberarterien gibt es in Form der sogenannten portalen Anastomosen (Hilusanastomosen), der translobären Anastomosen und der Kapselarterien.Keywords
