Prospective validation to prevent symptomatic portal vein thrombosis after liver resection

Figure 1 Patient flow of the analysis of portal vein thrombosis. Contrast-enhanced computed tomography was performed on the first day in 235 patients, who were categorized as high risk by three factors: Anatomical resection (165 patients), multiple resections (74 patients), and bile leakage (28 patients). Eight patients were detected with portal vein thrombosis in the high-risk group. E-CT: Contrast-enhanced computed tomography; POD: Post operative day; PVT: Portal vein thrombosis.

Figure 2 Portal vein thrombosis distribution and frequency. The sites of portal vein thrombosis included those around the umbilical portion (UP) (62.5%, 5/8 patients) and in the apex of the UP (12.5%, 1 patient), as well as the P8 resection stump (12.5%, 1 patient) and the anterior portal vein branch (12.5%, 1 patient).

Figure 3 Before and after anticoagulation therapy. A: In case 7, portal vein thrombosis (PVT) was found in the umbilical portion; B: PVT disappeared 140 d after starting anticoagulant therapy.
