title: Portal vein thrombosis after reconstruction in 270 consecutive patients with portal vein resections in hepatopancreatobiliary (HPB) surgery.
abstract: BACKGROUND
  This study was aimed to evaluate the occurrence of portal vein thrombosis after portal vein reconstruction.
  
  
  METHODS
  The portal veins were repaired with venorrhaphy, end-to-end, patch graft, and segmental graft in consecutive 270 patients undergoing hepato-pancreto-biliary (HPB) surgery.
  
  
  RESULTS
  Portal vein thrombosis was encountered in 20 of 163 of end-to-end, 2 of 56 of venorrhaphy, and 2 of 5 of patch graft groups, as compared with 0 of 46 of segmental graft group (p < 0.05, N.S., p < 0001, respectively). Portal vein thrombosis occurred more frequently after hepatectomy than after pancreatectomy (p < 0.0001). The restoration of portal vein blood flow was more sufficiently achieved in the early re-operation within 3 days after surgery than in the late re-operation over 5 days after surgery (p < 0.05).
  
  
  CONCLUSIONS
  The segmental graft might have to be more preferred in the portal vein reconstruction. The revision surgery for portal vein thrombosis should be performed within 3 days after surgery.
