摘要

Purpose

Knowledge of anatomical variations of the celiac trunk and hepatic arteries is crucial to prevent iatrogenic injury during endovascular interventions and hepatobiliary surgery.

Methods

A diagnostic abdominal computed tomography angiography (CTA) with 3D volume rendering and multiplanar reconstructions was performed in a 65-year-old male patient investigated for hepatocellular carcinoma for whom transarterial chemoembolization (TACE) was planned.

Results

CTA demonstrated a markedly elongated celiac trunk measuring 5.0 cm in length (assessed by centerline curved planar reconstruction from the aortic origin to the continuation as the splenic artery). The trunk gave origin sequentially to the left gastric artery (LGA) and common hepatic artery (CHA) before continuing directly as the splenic artery (SA). The right hepatic artery was replaced, originating from the superior mesenteric artery (SMA; Michels type III). The left hepatic artery (LHA) and gastroduodenal artery (GDA) arose normally from the CHA. No other visceral arterial anomalies were identified. Vessel diameters were: celiac trunk 6 mm, SMA 7 mm, CHA 2.5 mm, LHA 2 mm, replaced right hepatic artery (RRHA) 2.5 mm. The patient successfully underwent selective TACE via the replaced right hepatic artery.

Conclusion

Recognition of such combined vascular variants through high-quality pre-procedural CTA with multiplanar imaging is essential to prevent inadvertent injury and ensure safe interventional procedures.
