[Vascular exclusion during liver resection--an experimental rabbit model]

Area of Science:

• Surgical techniques
• Hepatic surgery
• Vascular surgery

Background:

• Major liver resections carry risks of hemorrhage and air embolism.
• Vascular exclusion of the liver (VEL) aims to mitigate these risks.
• The portal triad (VCI) is clamped above and below the liver during VEL.

Purpose of the Study:

• To present an experimental model for vascular exclusion of the liver (VEL).
• To evaluate the effectiveness of VEL in reducing surgical hazards.

Main Methods:

• An experimental model of VEL was developed.
• Twenty rabbits were used, divided into three groups based on the vascular exclusion pattern.
• The technique involves clamping the portal triad (VCI) above and below the liver.

Main Results:

• Complete VEL was demonstrated to reduce intraoperative hemorrhage.
• Complete VEL was shown to decrease the risk of air embolism.
• The experimental model provided insights into VEL application.

Conclusions:

• Vascular exclusion of the liver is a viable technique for major liver resections.
• VEL effectively minimizes the risks of bleeding and air embolism.
• Further research can build upon this experimental model.
