Post-operative developmental portal vein stenosis in a 16-year-old boy with progressive splenomegaly and pancytopenia, 1-year post-left lobe living donor liver transplantation. A: Color US image showing PV anastomotic stricture and post-stenotic dilatation. The anastomotic velocity elevation was borderline (3-4-fold) compared to the pre-anastomotic velocity (not shown); B: Multi-slice CT angiography, reconstructed image, demonstrating moderate PV anastomotic stricture with post stenotic dilatation of the graft PV; C: Percutaneous trans-hepatic digital subtraction portography image, demonstrating moderate PV anastomotic stricture (> 50 %) with post-stenotic dilatation. The pressure gradient was 7 mmHg; D: X-ray image during balloon dilatation of the stricture. The pressure gradient was normalized and stent placement was not performed. PV: Portal vein; LPV: Left portal vein.
