Technique for transrectal ultrasonography of the cranial mesenteric artery of the horse.

This research study demonstrated an effective use of transrectal ultrasonography for imaging the cranial mesenteric artery and its branches in horses.

Methodology

• The study involved the successful use of transrectal ultrasonography on 23 adult horses to image the cranial mesenteric artery and its branches from its source point at the aorta till several bifurcations distally.
• The technique required the use of three unique transducer positions to fully visualise the cranial mesenteric artery and its major branches.

Transducer Positions

• The first position involved the transducer imaging the caudal portion of the aorta from the aortic bifurcation cranially until the level of the cranial mesenteric artery. This initial position was used mainly for the location of the cranial mesenteric artery.
• The second position was utilized for imaging the origin of the cranial mesenteric artery. By adjusting the transducer’s position, researchers were able to clearly capture an image of the artery’s starting point.
• The third position was used for capturing the major branches of the cranial mesenteric artery. This final positioning permitted imaging of the artery’s primary branches, providing a clearer understanding of its anatomical details and structure.

Implications and Further Research

• This research demonstrates an effective non-invasive technique that could potentially serve as a diagnostic tool for veterinary practitioners working on the equine digestive system. This method offers detailed visualization of the cranial mesenteric artery, which could aid in the diagnosis of equine vascular diseases.
• Further studies may explore the efficiency and accuracy of this method in diagnosing specific equine diseases, as well as its applications within other animal species or other anatomical systems.
