Normal roentgen variant: aberrant right hepatic artery on computed tomography
Radiology
|May 1, 1980
Summary
A common variant, the aberrant right hepatic artery, appears between the portal vein and inferior vena cava in 20% of patients. Recognizing this normal variant is crucial for surgeons to prevent liver lobe necrosis.
Area of Science:
- Radiology
- Vascular Anatomy
- Surgical Anatomy
Background:
- Aberrant hepatic arteries are anatomical variations.
- Accurate anatomical knowledge is vital for liver surgery.
Purpose of the Study:
- To report the prevalence of aberrant right hepatic artery.
- To highlight the clinical significance of this vascular variant.
Main Methods:
- Computed tomography (CT) scans of 100 patients were reviewed.
- Vascular anatomy, specifically the hepatic artery, was analyzed.
Main Results:
- An aberrant right hepatic artery was identified in 20 out of 100 patients.
- The origin from the celiac or superior mesenteric artery was noted in 5 cases.
- The aberrant vessel was located between the portal vein and inferior vena cava.
Conclusions:
- Aberrant right hepatic artery is a frequent normal variant.
- Recognition is essential to prevent right hepatic lobe necrosis during hepatoduodenal ligament surgery.
