aceThree-dimensional anatomical classification and machine learning prediction of the P6a-right hepatic vein relationship: surgical implications for laparoscopic right anterior sectionectomy
Background The spatial relationship between the ventral branch of segment VI portal vein (P6a) and the right hepatic vein (RHV) significantly influences the anatomical complexity of the right hepatic fissure and the surgical outcomes of laparoscopic right anterior sectionectomy (LRAS). The ventral-P6a variant is often associated with higher surgical risks, yet preoperative prediction remains challenging. Methods This retrospective study included 100 patients who underwent triple-phase enhanced CT of the upper ab…
A logistic regression model using 3D CT anatomical measurements predicted whether the P6a portal branch lay ventral or dorsal to the right hepatic vein, offering a basis for preoperative risk assessment in laparoscopic right anterior sectionectomy.
The study was retrospective and included only 100 patients, and it assessed prediction of anatomical classification rather than demonstrating improved surgical outcomes.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-1918 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
