Systemic-to-pulmonary artery pressure ratio as a predictor of patient outcome following liver transplantation

Figure 1 Mean systemic-to-pulmonary artery pressure ration. MAP/mPAP = Mean systemic-to-pulmonary artery pressure ratio, measured at several times during the liver transplant: Baseline (30 min after incision), preanhepatic (1 h before IVC cross-clamp), anhepatic (15 min before reperfusion), neohepatic (15 min after reperfusion), and 1 h neohepatic (1 h after reperfusion). Group 1 (n = 66): Patients with MAP/mPAP ratio increase during anhepatic period; Group 2 (n = 25): Patients with MAP/mPAP ratio decrease or no change during anhepatic period. Data are shown as mean ± SD. P value was obtained using paired t-test. IVC: Inferior vena cava; MAP/mPAP: Mean systemic-to-pulmonary artery pressure.
