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

Figure 29 Intra- and post-operative hepatic artery vasospasm. A: Intraoperative Doppler US image showing high resistance of the HA with damped diastolic flow and normal systolic upstroke; B and C: Doppler US images of the HA, 2 d and 3 d post-operative after systemic administration of vasodilators, showing improvement of the diastolic flow and correction of the normal biphasic Doppler waveform. HA: Hepatic artery; IO: Intra-operative.
