Summary
Routine preoperative angiography before liver surgery can miss critical hepatic artery variations. This case highlights a duplicated hepatic artery, emphasizing the need for awareness of anatomical anomalies in surgical planning.
Area of Science:
- Vascular anatomy
- Surgical anatomy
- Medical imaging
Background:
- Preoperative angiography of the coeliac trunk and superior mesenteric artery is standard before liver resections and transplantations.
- Current angiography techniques often involve separate injections of coeliac trunk branches.
Observation:
- A case report details a duplicated hepatic artery.
- This anatomical variation was identified during preoperative imaging.
Findings:
- Selective angiographic studies may overlook essential variations in hepatic blood supply.
- A duplicated hepatic artery represents an uncommon but significant anatomical variant.
Implications:
- Awareness of anatomical variants is crucial for successful liver surgery.
- Radiologic and surgical implications of hepatic artery variations must be considered.
- Accurate preoperative assessment of hepatic vasculature is vital for patient safety.
