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

Figure 15 Post-operative hepatic vein stenosis in a patient with persistent ascites and graft dysfunction, 2 mo post-living donor liver transplantation. A: Post-operative B-mode US image showing tight stricture along the RHV anastomosis with the IVC (arrows); B: Pulsed Doppler image showing dampened hepatic venous spectral flow, loss of normal hepatic venous phasicity and anastomotic jet (5-fold) compared to the intrahepatic flow; C: MDCT angiography, coronal reconstructed image showing RHV anastomotic stricture (arrows); D: Digital subtraction trans-hepatic venography showing significant RHV anastomotic stricture (arrows), The pressure gradient was > 10 mmHg across the anastomosis. Balloon angioplasty and stent placement were performed. RHV: Right hepatic vein; IVC: Inferior vena cava.
