Eighteen patients with LDLT December 2006 and June 2008 were enrolled, and color Doppler ultrasonography was performed preoperatively and on postoperative days (PODs) 1, 3, 5, 7, 30, and 90 after transplantation. The changes in the portal blood flow mean velocity (PBV) and portal blood flow volume (PBF) were monitored, and their effects on hepatic function were observed simultaneously. Graft sizes were measured on PODs 7, 30, and 90 after the operation. The regeneration rates of grafts were calculated. PBF increased in the recipient group from 1081.17 \u00b1 277.50 to 2171.44 \u00b1 613.15 mL\/minute, and PBV increased from 15.01 \u00b1 5.67 to 56.00 \u00b1 22.11 cm\/s; they were both significantly higher than those in the donor group (<jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.01). On POD 1, serum aspartic aminotransferase, alanine aminotransferase, and total bilirubin all peaked; however, these indices in patients with PBF\/graft weight (GW) &gt; 300 mL\/minute \u00b7 100 g were significantly higher than those in patients with PBF\/GW &lt; 300 mL\/minute \u00b7 100 g. Livers in the recipient group regenerated rapidly. The graft regeneration rate reached 119.40% \u00b1 28.21% as early as 1 month post-transplantation. PBF and PBV on PODs 1 and 3 were greatly related to liver regeneration at 30 days. The portal venous flow in patients with portal hypertension after LDLT showed a high perfusion state, which could promote graft regeneration, but PBF\/GW after the operation should be controlled below 300 mL\/minute \u00b7 100 g in order to protect grafts from hyperperfusion injury.<\/jats:p>\n
