A Cadaveric Case Report of a Double Right Coronary Artery and Its Clinical Implications.

A double right coronary artery is one of the rarest variations of the coronary arterial system. This case report presents a unique variation: a right coronary and an accessory coronary artery arise from a single ostium within the right aortic sinus. The two vessels appeared externally to have a common trunk but were partitioned internally by a carina-like septum. This report underscores the importance of understanding the embryological development of coronary arteries and recognizing potential variations. It discusses the specific variation observed in this case and its clinical implications. The aim is to contribute to the limited literature on this condition and highlight the importance of recognizing and managing such anomalies in clinical procedures.

A Unique Arc of Bühler Variant Connecting the Arteries of the Foregut, Midgut, and Hindgut and Its Surgical Significance.

This case report presents a rare variation of the arc of Bühler (AOB) in a cadaver during the abdominal dissection assignment in the Ross Anatomy Lab at William Carey University College of Osteopathic Medicine. The AOB is a patent anastomotic channel between the celiac trunk and the superior mesenteric artery independent of the gastroduodenal artery and dorsal pancreatic artery. This report describes in detail a complex and extensive branching pattern of a unique AOB variant. Our findings contribute to the limited literature on this condition and emphasize the importance of thorough knowledge of vascular variations to avoid potential complications during surgical procedures.

Aberrant Left Colic Artery and Accessory Right Colic Artery: A Case Report and Surgical Implications.

During a routine dissection of the abdominal region in our department of anatomy's dissection laboratory, we found two variations of the vasculature of the gastrointestinal tract within the greater peritoneal and retroperitoneal compartments: an aberrant left colic artery (LCA) and an accessory right colic artery (RCA). The aberrant LCA originates from a common trunk (CT) that arises from the superior mesenteric artery instead of the inferior mesenteric artery. The CT continues for a short distance and terminates by dividing into a middle colic artery and an accessory RCA. The aberrant LCA and accessory RCA had abnormal courses; therefore, they are vulnerable to injury during surgical procedures of the region. Hence, a thorough knowledge of vascular variations is required to avoid potential complications.
