Table 2 Comparison of portal flow modulation techniques

Technique	Mechanism	Median FLR hypertrophy	Hypertrophy time	Main risks	Indications
Portal vein embolization (PVE)	Portal inflow occlusion	37%-40%	3-6 weeks	Low (abscess, thrombosis)	Insufficient FLR, most common bridge
Liver venous deprivation	PVE + hepatic vein embolization	50%-70%	2-4 weeks	Slightly higher dysfunction risk	Inadequate hypertrophy after PVE
Associating liver partition and portal vein ligation	Portal ligation + parenchymal transection	60%-80%	7-10 days	Higher: Infection, liver failure	Unresectable with rapid hypertrophy need

FLR: Future liver remnant.
