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

Figure 36 Gastroduodenal arterial steal. A: Intra-operative Doppler US image showing weak flow in the recipient HA (pre-anastomotic), with damped irregular systolic peak; B: Doppler US image after experimental clamping of the gastroduodenal artery, demonstrating improvement of the arterial waveform and regaining of the sharp systolic upstroke. Ligation of the gastroduodenal artery was then performed. HA: Hepatic artery.
