Summary
Complete hepatic vascular exclusion enables complex liver resections previously deemed unresectable. This technique, involving Pringle maneuver and vena cava clamping, demonstrates good liver tolerance for extended periods, facilitating challenging surgeries.
Area of Science:
- Hepatobiliary surgery
- Surgical oncology
- Vascular surgery
Background:
- Complex liver tumors often present unresectable challenges with conventional surgical methods.
- Hepatic vascular exclusion is an advanced technique requiring precise application.
Observation:
- Five cases of unresectable hepatic tumors were treated using complete hepatic vascular exclusion.
- This involved the Pringle maneuver combined with suprahepatic and infrahepatic inferior vena cava clamping.
Findings:
- Complete hepatic vascular exclusion allowed for extensive liver resections, including potential venous reconstruction.
- The procedure was tolerated well by the liver, even when clamping exceeded one hour (up to 85 minutes).
- Preoperative liver dysfunction was a key factor in successful tolerance.
Implications:
- This technique expands the possibilities for surgically managing extensive liver malignancies.
- Ex situ extracorporeal liver resections are considered to have a limited role compared to in vivo exclusion.
- Further research into optimizing hepatic vascular exclusion for complex liver resections is warranted.
