Abstract:
Objective To evaluate interventional therapy in the treatment of interposition graft stenosis or occlusion after mesocaval shunts.Methods The clinical data of 19 cases of artificial vessel stenosis or occlusion after mesocaval shunts for portal hypertension at our department from march 2009 to march 2012 were retrospectively analyzed.Results In the 19 cases with artificial vessels stenosis or occlusion developed after mesocaval interposition shunts for portal hypertension,there were 5 cases in which acute thrombosis occurred within a week after the surgery.Catheter directed thrombolysis was successfully conducted.In 6 cases in which shunt stenosis developing 1 to 8 years after surgery were managed by balloon dilatation or stent angioplasty successfully.The shunt graft occlusion occurred in 8 cases after 1 to 4 years of surgery was successfully managed and the shunt was reopened by balloon dilatation or stent angioplasty in 6 cases,and in 2 the procedure was failed for the guide wire can't go through the anastomotic site of artificial vessel-superior mesenteric vein.In 11 cases embolization of the esophagogastric varices was successfully carried out for postoperative standard anticoagulation.During a period of 3 months to 3 years follow-up,stenosis recurred 1 year after balloon dilatation in one case,and stenosis was managed by angioplasty successfully.Conclusions Interventional radiological techniques by percutaneous puncture through femoral vein-inferior vena cava-artificial vessel-portal vein (including catheter directed thrombolysis,balloon dilatation,stent placement,etc) are less traumatic,highly successful in the treatment of shunt stenosis or occlusion after mesocaval shunts in portal hypertension.
