BACKGROUND: Many anatomical variations have been associated with the Celiac Trunk, of which most are classified as being asymptomatic. CASE PRESENTATION: In this article, we describe yet another anatomical variation involving the Celiac Trunk, Superior Mesenteric artery and the Inferior Pancreaticoduodenal Artery during routine cadaveric dissection. We identified a fourth branch of the Celiac trunk (quadrification) that communicated with the Superior Mesenteric artery at the point of origin of the Inferior Pancreaticoduodenal artery which we concluded to be the Anterior Inferior Pancreaticoduodenal artery. CONCLUSION: This anastomosis could be essential in the case of occlusion between the Celiac Trunk and the Superior Mesenteric artery.

BACKGROUND: Anomalies associated with the vertebral arteries are relatively rare. The vertebral arteries arise from the first part of the Subclavian artery and pass through the transverse foramina of C6 through C1. CASE PRESENTATION: However, in this article, we describe a unique variation in the anatomical orientation of the right vertebral artery during a routine cadaveric neck dissection where the right vertebral artery gives an oblique branch from the extradural segment (C2) forming a fenestrated Vertebral artery. CONCLUSION: Despite the lack of established clinical significance, multiple co-morbid vascular malformations are yet associated with the Vertebral artery fenestration with a possibility of iatrogenic injuries if not taking into cognisance.
