Preoperative predictors of portal vein thrombosis after splenectomy with periesophagogastric devascularization

Figure 1 The anatomy of the lower part of the esophagus and periesophagogastric area after surgery. 1: Gastric branch of gastric coronary vein; 2: Esophageal branch of gastric coronary vein; 3: High esophageal branch of gastric coronary vein; 4: Aberrant high esophageal branch of gastric coronary vein; 5: Gastric short vein; 6: Gastric posterior vein; 7: Left subphrenic vein.

Figure 2 The diameter of the portal vein is negatively correlated with the preoperative maximum portal vein flow velocity. V_max: The mean maximum portal blood flow velocity; D: Portal vein diameter.

Figure 3 Receiver operating characteristic curve of the mean maximum portal blood flow velocity and V_max/portal vein diameter. V_max: The mean maximum portal blood flow velocity; D: Portal vein diameter.

Figure 4 Receiver operating characteristic curve of hepatic congestion index and portal vein diameter. CI: Congestion index; D: Portal vein diameter.
