Summary

Portal vein embolization (PVE) can help increase liver remnant size before major liver resection, with low complication rates. This technique is indicated for selected patients to reduce post-surgery complications.

Area of Science:

  • Hepatobiliary Surgery
  • Interventional Radiology

Background:

  • Major liver resection complications persist despite surgical advances.
  • Inadequate postresection hepatic size and function are key concerns.
  • Portal vein embolization (PVE) aims to increase liver remnant volume via hypertrophy.

Purpose of the Study:

  • Review techniques, complications, and outcomes of PVE before liver resection.
  • Evaluate the efficacy and safety of PVE in surgical candidates.
  • Clarify indications for PVE in liver surgery.

Main Methods:

  • Medline search for studies on PVE preceding hepatic resection.
  • Review of PVE techniques, associated complications, and patient outcomes.
  • Analysis of different embolic agents and their effectiveness.

Main Results:

  • PVE complications occur in <5% of patients; no single embolic agent is superior.
  • Average remnant liver volume increase is 12% of total liver volume.
  • Morbidity and mortality rates after resection are reduced, especially in patients with compromised liver function.

Conclusions:

  • PVE is a safe adjunct, not increasing risks of major liver resection.
  • PVE is indicated for selected patients needing major liver resection.
  • Further prospective studies are needed to refine PVE indications.
