Temporary portal decompression during liver transplantation: a video review of the different techniques.

ABSTRACT

PURPOSE: Temporary portal decompression (TPD) during liver transplantation (LT) remains a divisive technical issue in the liver transplant community. In this video-based article, we show the technical details of the different techniques used for TPD during LT. METHODS: An early portal section, before liver mobilization, should be preferred in order to achieve hepatectomy of a totally devascularized liver. Portal decompression can be achieved through direct right portocaval shunts and indirect portosystemic shunts (i.e., mesentericosaphenous and portosaphenous shunts). RESULTS: The preference for direct portocaval or indirect portosystemic shunts is tailored on patients and anatomical characteristics. Each of these three techniques presents specific indications, limitations, and advantages. CONCLUSION: TPD during LT can be achieved through different techniques that aim to facilitate the recipient hepatectomy, reduce the blood loss, and maintain hemodynamic stability.
