Portal vein replacement by hepatic vein transposition

Area of Science:

• Hepatobiliary surgery
• Vascular reconstruction
• Surgical oncology

Background:

• Portal vein resection is challenging in extended liver surgery.
• Existing methods for portal vein reconstruction have limitations, including additional incisions or unsuitable graft diameters.
• Tumor infiltration of the portal vein necessitates effective reconstruction strategies.

Purpose of the Study:

• To present a novel technique for portal vein replacement using the excised hepatic vein.
• To offer a viable solution for portal vein reconstruction in major liver resections involving portal vein infiltration.
• To overcome the limitations of current venous graft procurement methods.

Main Methods:

• Development of a new technique for portal vein replacement.
• Utilizing the excised hepatic vein as a graft.
• Application in major liver resections with portal vein tumor involvement.

Main Results:

• Successful portal vein reconstruction was achieved using the excised hepatic vein.
• The technique avoids the need for additional incisions for graft harvesting.
• The method is suitable for cases where the hepatic vein has a safe distance from the tumor infiltration.

Conclusions:

• The excised hepatic vein is a feasible and advantageous graft for portal vein replacement in specific liver resections.
• This technique offers an alternative to conventional methods, potentially improving outcomes in complex hepatobiliary surgeries.
• Further evaluation is warranted to establish the long-term efficacy and applicability of this method.
