Abstract
The aim of the study: to highlight the role of PV hemodynamics and its impact on the outcome of LT and to determine the level of PVP that is adequate for graft regeneration and reduction of graft injury and so improve outcome of LT.Results: PVV, HA PSV and HA RI declined gradually but significantly post-LT. Indices of graft functions and PO PVV were higher in the early mortality group. IO and PO PVV were significantly higher in the SFSS group. The best cutoff value for prediction of SFSS using PO pre-anastomotic PVV = 55.5 cm/sec & PO post- anastomotic PVV = 126.5 cm/sec. The best cutoff value for prediction of SFSS using pre-clamping PVP = 24.5 mm Hg & post-perfusion PVP = 16.5 mmHg. There is a statistically significant negative correlation between mean PO PVV with mean PO HA PSV. PVP correlated significantly with indices of graft functions after LDLT. Conclusion: PVP and PO PVV are significant hemodynamic factors that influence the functional status of the transplanted liver. SFSS which has a negative impact on morbidity and mortality post-LDLT, could be predicted by cut-off values for the PVP and PO PVV
