In situ subtotal spleen resection combined with selective pericardial devascularization for the treatment of portal hypertension

Figure 2 Peripheral blood platelet level and perioperative portal system thrombosis. A: The free portal vein pressure after subtotal splenectomy decreased significantly after surgery (^bP < 0.01 vs pre-operation); B: The platelet level increased significantly 1 mo after subtotal splenectomy. (^cP < 0.001 vs pre-operation); C: The platelet level after subtotal splenectomy increased more slowly than that after total splenectomy (^aP < 0.05, ^cP < 0.001 vs subtotal splenectomy).
