Coexistence of rare arteries in the human celiaco-mesenteric system

Area of Science:

• Anatomy
• Vascular Biology
• Medical Imaging

Background:

• The celiacomesenteric arterial system is crucial for supplying blood to major abdominal organs.
• Variations in this system can impact surgical planning and diagnostic interpretations.
• Understanding rare anomalies aids in refining anatomical classifications.

Observation:

• Postmortem examination revealed multiple rare anomalies in a Japanese adult male's celiacomesenteric arterial system.
• Key observations included independent origins of major arteries from the aorta and unusual branching patterns.
• Specific anomalies involved the left gastric, common hepatic, splenic, and superior mesenteric arteries, as well as accessory hepatic and colic arteries.

Findings:

• The study identified independent origins for the left gastric, common hepatic, splenic, and superior mesenteric arteries from the abdominal aorta.
• Anomalous branching included the anterior inferior pancreaticoduodenal artery supplying hepatic arteries and accessory vessels.
• Anastomoses between the common hepatic and superior mesenteric arteries were noted, alongside accessory hepatic and colic arteries originating from the left gastric and splenic arteries, respectively.

Implications:

• These documented anomalies highlight the significant variability within the celiacomesenteric arterial system.
• The findings support a proposed typological system for classifying celiacomesenteric vascular anomalies.
• Accurate documentation of rare vascular variations is essential for clinical practice and anatomical research.
