Fig. 1. Spectral Doppler ultrasound and carbon dioxide (CO₂) angiogram before and after gastroduodenal artery (GDA) embolization. (A) Spectral Doppler ultrasound shows no detectable flow in the MHA on postoperative day 7. (B) CO₂ angiogram of the common hepatic artery shows a diminutive proper hepatic artery and GDA artery with mean diameter of 3.7 mm (range, 2.2–4.8 mm). The common hepatic artery was normal. (C) CO₂ angiogram of common hepatic artery after GDA coil embolization. (D) Post-embolization spectral Doppler ultrasound showing normal velocities and arterial resistance index within MHA after GDA embolization. MHA, main hepatic artery.
