title: Safety and efficacy of hepatic vein reconstruction for colorectal liver metastases.
abstract: BACKGROUND
  Colorectal liver metastases with hepatic vein (HV) involvement may require combined resection of the liver and HV. However, the short- and long-term outcomes of such a procedure remain unclear.
  
  
  METHODS
  We reviewed 16 cases of liver resection with major HV resection and reconstruction.
  
  
  RESULTS
  The patients had a median age of 58.5 years (range, 50-74 y). In total, 18 HVs were reconstructed using a customized great saphenous vein graft (n = 10), direct anastomosis (n = 1), external iliac vein (n = 2), portal vein (n = 1), umbilical vein patch graft (n = 3), or ovarian vein patch graft (n = 1). There was no hospital mortality, and the morbidity rate was 50%. With a median follow-up period of 30 months (range, 4-89 mo), 3 patients died of tumor recurrence and 13 were alive with (n = 6) and without (n = 7) disease. Cumulative 1-, 3-, and 5-year survival rates were 93%, 76%, and 76%, respectively.
  
  
  CONCLUSIONS
  HV resection and reconstruction combined with liver resection can be performed safely with reasonable long-term results.
