title: Changes in left portal vein diameter in live liver donors after right hemihepatectomy for living donor liver transplantation.
abstract: OBJECTIVE
  To evaluate changes in left portal vein(LPV) diameter and its effect on changes of remnant liver volume(RLV) and splenic volume(SV) in live liver donors after right hemihepatectomy.
  
  
  METHODS
  From November 2008 to May 2009, 92 live liver donors were included. On preoperative, postoperative 1-week and 1-month CT, we measured LPV diameters(LPVB, LPV1W, LPV1M), RLVs(RLVB, RLV1W, RLV1M) and SVs(SVB, SV1W, SV1M). Percentage-intervalchanges were analyzed. The relationships between %LPV1W-B and other parameters were evaluated by univariate regression analyses.
  
  
  RESULTS
  On postoperative 1-week, LPV1W invariably decreased. However, RLV1W and SV1W increased. %RLVB and %RLV1W-B were significantly associated with %LPV1W-B(P=.016,.011). On postoperative 1-month, mean %LPV1M-1W, %LPV1M-B, %SV1M-1W and %SV1M-B were 108.1±9.8%, 82.9±11.8%, 99.3±11.4% and 146.9±23.0%. Although %RLV1M-B or %RLV1M-1W were not related with %LPV1W-B(P=.034,.401), there were negative correlations between %LPV1W-B and %SV1M-1W or %SV1M-B(P=.004,.007).
  
  
  CONCLUSIONS
  LPV diameter mostly decreases following right hemihepatectomy and improves spontaneously. Besides extent of hepatectomy, %LPV1W-B may be another indicator predicting splenic enlargement.
