Venous drainage map of the liver for complex hepatobiliary surgery and liver transplantation

Abstract

Background: Inflow and outflow patency of the liver parenchyma is required to maximize the metabolic

Parenchyma sparing multicomponent liver resection strategy for multiple bilobar synchronous colorectal cancer metastasis

“…CT data and liver revision on II surgical stage of this case repost confirmed the fact that UFV is able independently drain venous blood from the isolated 3rd segment of the liver. UFV is third‐order hepatic vein flowing in to the MHV or to the LHV‐MHV confluence zone and drain blood from liver parenchyma between the left lateral section and 4th segment …”

“…UFV is third-order hepatic vein flowing in to the MHV or to the LHV-MHV confluence zone and drain blood from liver parenchyma between the left lateral section and 4th segment. 8 Applying the R1 vascular resection approach is an appropriate and conditionally safe method from the oncological point of view in CRC patients. 9 However, if true vascular invasion is confirmed, liver resection should be performed in a single block with a vascular component.…”

A retrospective comparative study of venous vs nonringed expanded polytetrafluoroethylene extension grafts for anterior sector outflow reconstruction in right lobe living donor liver transplantation

“…Right hepatic vein (RHV) drains the posterior sector and sometimes anterior superior part of the AS of the RL of the liver. Except for this dorsal part of segment VIII, rest of AS is drained by MHV, mean drainage proportion being 32.7% of the entire hepatic venous drainage . The consequences of venous congestion in the AS of RL graft may result not only in impaired graft regeneration but also immediate liver dysfunction, graft rupture, small‐for‐size syndrome, and graft loss .…”

“…Although 5 mm cutoff seems most practical, we reconstruct lesser size (<5 mm) in case of low GRWR (<0.8) especially in the presence of high portal hypertension. We believe that the drainage of segment V is very important not only because its drainage extends to part of segment VI in 8%‐13% but also consequent congestion above hilum makes biliary anastomoses difficult.…”

Porción Hepática Izquierda (A05.8.01.037)

“…Sano et al (2003) reportaron la vena de la fisura umbilical en 81 % de 21 casos. Tani et al (2016) describieron que la vena hepática izquierda, la intermedia y la derecha drenan en promedio 20,7 %, 32,7 %, y 39,6 % del parénquima hepá-tico, respectivamente, las venas accesorias drenan el 7 % restante. La vena hepática derecha media e inferior drenan el 8 % y 10,6 %, respectivamente.…”
