Abstract:
Objective To investigate the change of inferior vena cava pressure (IVCP) in type Ⅱ Budd-Chiari syndrome patients undergoing atrial caval shunting and its relationship with postoperative artificial blood vessel (ABV) patency rate.Methods We recruited 209 patients who had undergone atrial caval shunting for type Ⅱ Budd-Chiari syndrome and evaluated IVCP,right atrial pressure (RAP) and free portal vein pressure (PFP) before and after ABV opening.Presure changes were compared by t-test.These patients were followed up by color Doppler ultrasonograthy for ABV patency.The correlation between IVCP and postoperative ABV patency were analyzed By Kaplan-Meier test.Results IVCP (t =0.56,P ＜ 0.05)and PFP (t =0.72,P ＜ 0.05) decreased and RAP increased significantly after ABV opening (t =0.52,P ＜ 0.05).Follow up result showed that ABV patency rate was lower in patients with IVCP descent ＜ 1 kPa than those with IVCP descent ＞ 1 kPa (P ＜ 0.05).Conclusions Significant IVCP descent correlates with high ABV patency rate after atrial caval shunting in type Ⅱ Budd-Chiari syndrome patients.
