Anticoagulation therapy prevents portal-splenic vein thrombosis after splenectomy with gastroesophageal devascularization

Figure 1 Changes in platelet count and prothrombin time/international normalized ratio in group A and group B. It was not different in platelet (PLT) between the two groups (P = 0.981), but it was statistically different in prothrombin time/international normalized ratio (PT/INR) between the two groups (P = 0.020). PT/INR in group A had no sequential changes pre- and post-operatively (P = 0.479) and PT/INR in group B was increasing gradually from postoperative day 7 with statistical difference (P = 0.003). POD: Postoperative day.
