Abstract:

Objective To evaluate the therapeutic results of vascular plug-assisted retrograde transvenousobliteration（RTO）for treatment of splenic and renal shunt vein following liver transplantation. Methods 3 patients who had undergone vascular plug-assisted RTO were etrospectively evaluated from August 2015 to February 2016. Percutaneous transhepatic angiography of the portal vein was performed in all patients，and then retrograde transvenous placement of a vascular plug in the shunt vein. The clinical data，imaging follow-up data，complications of interventional treatment and prognosis was summarized. Results In all patients，the percutaneous transhepatic angioplasty and placement of the vascular plug successfully，with no procedure-related complications. Follow-up CT after vascular plug-assisted RTO showed complete thrombosis of shunts in all patients，follow-up ultrasonicdoppler within 1 week and 1 month the portal vein blood flow increase obviously. 1 patient received second liver transplantation because of the biliary tract complications. Improvement in Child-Pugh score was observed in the other two patients 1 month after vascular plug-assisted RTO. Conclusion Vascular plug-assisted RTO is technically safe and seems to be clinically effective for treatment of splenic and renal shunt vein post-transplantation.
