A portacaval anastomosis or portocaval anastomosis is a specific type of circulatory anastomosis that occurs between the veins of the portal circulation and the vena cava, thus forming one of the principal types of portasystemic anastomosis or portosystemic anastomosis, as it connects the portal circulation to the systemic circulation ...

2024年4月22日 · As their name suggests, cavo-caval and porta-caval anastomoses are essentially anastomoses between two or more branches that reach unrelated major trunks of veins. Cavo-caval anastomoses. The cavo-caval anastomosis connects between the superior and inferior vena cava; they can

It has long been debated whether cava anastomosis should be performed with the piggyback technique or cava replacement, with or without veno‐venous bypass (VVB), with or without temporary portocaval shunt (PCS) in the setting of liver ...

Cavocaval anastomoses are venous connections between vena cava superior and vena cava inferior. These connections are particularly functional in restricting flow through the normal bloodstream. When obstructing the trunk, the veins thus provide an alternative flow path, most often in the area of the anterior abdominal wall. Portocaval Anastomosis

End-to-side portocaval shunt anastomoses are performed by dividing the portal vein at its bifurcation and turning the PV posteriorly for anastomosis to the vena cava. The anastomosis can be created using either interrupted or continuous sutures.

Objectives: To identify whether different cava anastomotic techniques and other maneuvers benefit the recipient regarding short-term outcomes and to provide international expert panel recommendations. Data sources: Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central.

2016年12月21日 · Other techniques involve complete recipient hepatectomy with preservation of the IVC, followed by piggyback (PB) to the hepatic veins, or side-to-side (SS) caval anastomosis. These latter techniques only require partial occlusion of the IVC and allows maintenance of some venous return during caval anastomosis.

2021年6月30日 · Herein, we present our standardized step-by-step technique for the realization of a caval one-shot side-to-side anastomosis (OSSSA) using a linear stapler. A Satinsky vascular clamp is placed in a top down direction to realize a longitudinal partial clamping of …

Caval anastomosis in liver transplantation has been modified to avoid outflow complications. Classic cava replacement is rarely indicated; most liver transplantation teams use a piggy-back (PB) technique. At the start of our liver transplantation program, we opted for a latero-lateral (L-L) caval anastomosis.

2023年8月14日 · The stapled side-to-side cavo-caval anastomosis during orthotopic liver transplantation may offer some benefits, including shortening of the graft ischemia period, improved feasibility of anastomosis in large liver grafts or inconvenient caudate anatomy and better quality of the anastomotic line.
