GONZALEZ, María Catalina et al. Intrahepathic portal revascularization following right portal vein ligation: a case report. Rev. Méd. Urug. [online]. 2020, vol.36, n.4, pp.301-310.  Epub 01-Dez-2020. ISSN 0303-3295.  https://doi.org/10.29193/rmu.36.4.15.

Left or right portal vein ligation to prevent post-operative liver failure in the case of extreme hepatectomy constitutes a procedure with a good prognosis, as it causes contralateral liver hypertrophy.

However, its revascularization has been proved by intrahepatic porto-portal anastomoses, which could result in a reduction of the expected or required hypertrophy.

The study aims to record a clinical case of intrahepatic revascularization of the portal vein, an unwanted event of the two-stage hepatectomy to treat bilobar hepatic metastasis of colorectal origin, and describe alternatives to avoid or treat such revascularization.

Palavras-chave : Portal vein ligation; Two-stage hepatectomy; Neoplasm metastasis; Liver neoplasms; Colorectal neoplasms.
