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

Figure 20 Intra-operative portal vein stenosis. A: B-mode US image showing PV anastomotic stricture; the suture line is seen encroaching on the lumen (arrows) with high level echoes seen at the site of anastomosis, representing turbulence of flow; B: Pulsed Doppler image demonstrating anastomotic elevation of the PV velocity (6-fold) compared to the pre-anastomotic velocity. The pressure gradient across the anastomosis was 8 mmHg, indicating the need for surgical anastomotic revision. PV: Portal vein.
