Portal vein variations of the right lobe and surgical implications in rats. 3D visualization.

<p><b>A)</b> Visualization of portal vein vascular tree. Single supply of RSL and RIL was observed in 4 of 14 cases. <b>B)</b> Portal venous territories. A ligation of right superior PV or resection of RSL without compromising of portal venous supply of RIL is possible. <b>C)</b> Portal venous territories. The craniodorsal part of the RIL is supplied by right superior PV in 10 of 14 cases. <b>D)</b> Portal venous territories. Ligation of right superior PV or resection of RSL leads to lack of portal supply in half of the right inferior lobe. Red line is resection line or ligation of PV. Encircled is the right lobe. ICL-inferior caudate lobe, LML-left median lobe, LLL-left lateral lobe, PV-portal vein, RIL-right inferior lobe, RML-right median lobe, RSL-right superior lobe, SCL-superior caudate lobe.
