Abstract
ObjectiveTo evaluate the effective and safety of ultrasound-guided percutaneous portal vein guide wire placement adjunct to thrombolytic catheter, which treating portal vein thrombosis after liver transplantation.
MethodsFrom Jan 2012 to Dec 2015, a total of 6 patients (5 male, 1 female, average age 50.6 years old, age range 41-65 years old ) with portal vein thrombosis after liver transplantation were retrospectively studied. The diagnosis was confirmed by contrast enhanced ultrasound (CEUS) with hypoechonic and no enhancement in portal vein. With ultrasound-guided a 18-guage guide wire was placed in right branch of portal vein, and a guidewire was placement. After exchanging the catheter, the thrombosis was confirmed again by venography. A thrombolytic catheter was placed and local thrombolysis therapy was performed.
ResultsThe guidewires were successfully placed in 6 patients. The thrombolytic catheters were successfully placed in 5 patients (day 2-60 after operation), and failed in 1 patient (9 years after operation). With 5-11 days urokinase injection, the patency of portal vein was found in 5 patients, of which 4 patients was treated by angioplasty and stent placement. With 16-31 months follow-up, the patency of portal vein was maintained. Neither server complication nor related-death was occurred.
ConclusionsUltrasound-guided percutaneous portal vein guide wire placement adjuncts thrombolytic catheter is effective and safety for treating portal vein thrombosis after liver transplantation.
