Application of catheter directed thrombolysis in the treatment of Budd-Chiari syndrome with inferior vena cava thrombosis / 国际外科学杂志

ABSTRACT

Objective To investigate the feasibility and safety of catheter thrombolysis in the treatment of Budd-Chiari syndrome (B-CS) with inferior vena cava(IVC) thrombosis.Methods A retrospective analysis of the clinical data of 21 cases of B-CS with IVC thrombosis in the First Affiliated Hospital of Zhengzhou University from January 2011 to September 2014 was conducted.They were divided into 2 groups,12 cases of fresh thrombus group,while 9 cases of old thrombus group.All cases were couducted with catheter directed thrombolysis through the right femoral vein,then regularly with color doppler examination,evaluating thrombolytic effect.When thrombus disappearing,intervention or (and) operation treatment was conducted,then postoperative following-up.Results There were 16 cases in which thrombus dissolving completely within 15 days(9 cases of fresh thrombus and 7 cases of old thrombus,P =0.536).In 1 case,thrombosis dissolved completely 20 days later.There were 3 cases combined with pre-dilating technology (thrombosis dissolved completely).When thrombosis completely dissolved,the mean catheterization time of fresh thrombus group was (10.78 ± 2.97)d,while the old thrombus group was (14.13 ± 3.41)d(P =0.06).The short-term (less than 15 days) dissolution rate was 76.19％ (16/21),and the total efficiency rate was 90.48％ (19/21).Complications occurred in 4 cases.The incidence of severe complications was 4.76％ (1/21).Postoperative follow-up with Color Doppler ultrasound in 1 to 12 months,1 case recurred after 5 months.The rest did not recurred.the recurrence rate was 4.76％ (1/21) within following up time.Conclusions The catheter thrombolysis is an important link in the treatment of B-CS with thrombosis of IVC,which is simple,safe and effective,with low incidence of complications.It can be used as the preferred treatment for this type of B-CS.
