Doppler ultrasonography in living donor liver transplantation recipients: Intra- and post-operative vascular complications

Figure 19 Portal vein pseudo-stenosis in a clinically silent patient. A: Post- operative color Doppler image, 2 mo post living donor liver transplantation demonstrating anastomotic stenosis 50%-60%, with elevation of the anastomotic velocity (4-fold) compared to the pre-anastomotic velocity; B: Percutaneous trans-hepatic digital subtraction portography image, showing anastomotic stricture (arrows) however, the pressure gradient across the anastomosis was 3 mmHg and angioplasty and stent placement were not performed. PV: Portal vein; HA: Hepatic artery.
