Abstract：
BACKGROUND:This study aimed to explore the effects of early antiplatelet therapy (APT) for portal vein thrombosis (PVT) in patients with cirrhotic portal hypertension after splenectomy with gastro-oesophageal devascularization. METHODS:We retrospectively analysed 139 patients who underwent splenectomy with gastro-oesophageal devascularization for portal hypertension due to cirrhosis between April 2010 and December 2016. Based on the post-operative platelet values, we used two different APT regimens: APT was started when platelet counts were increased to 200 × 109 /L or above (group A, n = 64) or 300 × 109 /L or above (group B, n = 75). We took note of the patients' clinical symptoms, operative factors and biochemical indicators. RESULTS:Platelet count, mean platelet volume, D-dimer and pancreatic fistula were closely related to the development of PVT. Early APT was an independent protective factor for PVT. The incidence of post-operative PVT was 15.1% (21/139) overall, 4.7% (3/64) in group A and 24% (18/75) in group B; there was a significant difference between groups A and B (χ2 = 10.042, P = 0.002). CONCLUSION:Platelet count, mean platelet volume, D-dimer and pancreatic fistula were independent risk factors for the development of PVT after splenectomy with gastro-oesophageal devascularization. Selection of the appropriate timing for early APT according to the post-operative platelet count was feasible. Moreover, the use of aspirin combined with dipyridamole was safe and effective for early prevention of PVT.
