Introduction Percutaneous
transluminal
angioplasty
(PTA), with or without stent placement, has become the
treatment of choice for portal vein complications (PVC)
following liver transplantation. We aimed to assess long-
term outcomes of intervention in paediatric transplant
recipients, in a single institution.
Materials and Methods 227 children received 255 trans-
plants between November 2000 and September 2016. 30
patients developed PVC of whom 21 had percutaneous
intervention. Retrospective clinical and procedural out-
come data on these 21 patients were collected.
Results 21 patients, with median age 1.7 years (range
0.4–16.2), underwent 42 procedures with PTA with or
without stenting. 36 procedures were for PV stenosis and 6
for PV thrombosis. Treatment was with primary PTA, with
stenting reserved for suboptimal PTA result or restenosis
within 3 months. 28 procedures were performed with PTA
and 13 with stenting. Technical success ([50% reduction
in mean pressure gradient, absolute pressure gradient
B4 mmHg or venographic stenosis\30%) was achieved in
41 procedures. Failure to recanalise a thrombosed PV
occurred in 1 procedure. There were no major procedural
complications. Patients were followed-up with serial
Doppler ultrasound surveillance. Kaplan–Meier estimated
