Summary
A rare arterial variant supplying the pancreas and colon was discovered during cadaveric dissection. This unique branching pattern of the superior mesenteric artery (SMA) is crucial for surgical planning in pancreatic and colorectal procedures.
Area of Science:
- Anatomy
- Vascular Surgery
Background:
- Pancreatic and colonic vasculature exhibit significant variability.
- Understanding these variations is critical for successful surgical interventions.
Purpose of the Study:
- To document a previously unreported arterial branching variant.
- To enhance anatomical knowledge for pancreatic and colon surgery.
Main Methods:
- Cadaveric dissection of a 72-year-old male donor.
- Identification of an anomalous branching pattern of the superior mesenteric artery (SMA).
Main Results:
- An unnamed artery originated from the posterior middle colic artery (MCA).
- This artery supplied multiple segments of the pancreas (head, uncinate process, body, tail).
- A transverse branch crossed the SMA anteriorly, supplying parts of the small intestine.
Conclusions:
- This case presents a novel arterial variant connecting the colon and pancreas.
- Awareness of this variant can aid in reducing complications during colorectal and pancreatic surgeries.
