title: Liver resection with selective hepatic vascular exclusion: a cohort study.
abstract: OBJECTIVE
  To report our experience on the safety and efficacy of hepatic resection under selective hepatic vascular exclusion (SHVE).
  
  
  METHODS
  SHVE was used in 246 consecutive patients undergoing major or complex liver resection in our center. Preoperative demographic and clinical data, details of the surgical procedure, pathologic diagnosis, postoperative course, and complications were collected prospectively.
  
  
  RESULTS
  From January 2000 to July 2007, liver resections were performed under SHVE in 246 patients; total SHVE, right partial SHVE, and left partial SHVE in 145, 54, and 47 patients, respectively. SHVE was converted to total hepatic vascular exclusion in 3 patients because the tumor invaded the wall of the inferior vena cava. Hemodynamic tolerance to SHVE was excellent, with only a slight increase in systemic and pulmonary vascular resistance during clamping. There were no deaths and the morbidity rate was 24.8%. The mean hospital stay was 9.6 days (range, 8-18).
  
  
  CONCLUSIONS
  Our study showed that SHVE was safe, efficacious, and it was applicable to liver tumors which were near, but had not invaded into the inferior vena cava.
