Abstract Objective To investigate the criteria of prophylaxis of splenic artery banding (SAB) on splenic artery steal syndrome (SASS), and to evaluate their clinical outcomes and reliability in recipients undergoing orthotopic liver transplantation (OLT). Methods 127 consecutive OLT recipients suffered from liver cirrhosis combined with splenomegaly. Ratio diameter of pre-OLT splenic artery(SA) to which of common hepatic artery (SA/CHA) ≥1.5 and intra-OLT peak systolic velocity (PSV)＜30 cm/s had been performed SAB in this hospital between January, 2004 and December, 2013. We reviewed their clinical data of clinical outcomes and safety. Results The sluggish and dim PSV of the patent hepatic artery increased immediately in the mean PSV from (19.34±5.45)cm/s to (45.89±9.13)cm/s (P<0.001), and resistivity index (RI) of HA rehabilitated to reasonable level (0.5-0.8) after intervention, without SASS or any artery-related complication detected. However, there were 17 cases SASS out of 191 patients exempted from SAB because of their intra-OLT PSV≥30 cm/s, and 11 cases of them secondary by HA thrombosis. Conclusions SASS is an important but often underdiagnosed cause of graft ischemia after OLT. Prophylactic SA banding deserves to be applied in patients risking on SASS for satisfactory results and reasonable safety.
