RESUMO
BACKGROUND: Variations in human anatomy have been associated with numerous clinical correlations that may affect patient care. In this article, we present a unique variation of the medial cord of the brachial plexus about the axillary artery and subscapular artery. The precise assessment of this unique morphology was performed during a cadaveric dissection. CASE PRESENTATION: Contrary to the general course of the medial cord of the brachial plexus, this report demonstrates a rare splitting of the medial cord around the axillary artery and a second abnormal communication between the posterior and medial cords that show a "nutcracker-like" syndrome involving the subscapular artery. CONCLUSION: Such variations could make surgeries challenging. We also infer that these anatomical variations could make gliding therapy inefficient in any motor dysfunction initiating from the brachial plexus.
RESUMO
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.
