- 4. Dissection of Groove betweeen Right and middle left hepatic veins
- 6. MOBILIZATION OF LIVER • After that right lobe is mobilized from it’s ligamentous attachments as shown in figures. • Several short hepatic veins corsing from liver to IVC needs to be ligated. • Idea should be to elevate right lobe of liver from the IVC.
- 12. Dissecting Right Hepatic Vein • Make a good groove between right and middle-left during top dissection. • As shown in first figure, you will encounter hepato- caval ligament. • Dissect it and divide it between clamp (few small veins may run through it) • After that you will find right hepatic vein. Create tunnel behind ir and connect it to the initial groove you have created. Now Loop It.
- 13. Hepatocaval or Makuchhi’s ligament
