Liver venous deprivation (LVD) enhances outcomes versus portal vein embolization (PVE) among liver cancer patients needing preoperative liver augmentation.

• LVD significantly boosts future liver remnant growth by 24.57% and daily volume by 4.30%.
• It shortens surgery wait times by over 5 days and operation duration by nearly 43 minutes.
• Resection completion rates improve by 73%, while rates of postoperative liver failure and 90-day mortality decrease by 55%.

Consider LVD as a viable option for patients with insufficient liver remnants, but note the need for further studies on long-term effects.
