Background: Knowledge regarding the course and termination of the radial artery before harvesting it for coronary artery bypass graft surgery (CABGS) is important. The brachial artery terminates at the neck of radius into radial and ulnar arteries.Purpose of the study: To know the various patterns of anomalous division ofthe radial artery.
Methods:The study included 50 upper limb specimens from the Department of Anatomy, Sree Narayana Institute of Medical Sciences, Ernakulam. The specimens were fixed with 10% formalin solution and the radial artery was exposed from its origin till termination and observations were noted down.Results: The present study revealed that, radial artery usually was arising from brachial artery at the level of neck of radius. The variants observed included high bifurcation of brachial artery, division of radial artery into palmar and dorsal branches in the forearm and anomalous course of radial artery in the region of anatomical snuff box.
Conclusion:The present study has revealed the anomalous division and course of radial artery around the wrist and anatomical snuff box and the knowledge of such anomalous course is important for diagnostic, interventional and surgical procedures.
During routine cadaveric dissection done for the undergraduate students in 2013, at the Department of Anatomy, Mysore Medical College and Research Institute, Mysore an accessory muscle head in the left forearm of a male cadaver was observed which was supplied by a branch of anterior interosseous nerve. Gantzer's muscle is an accessory portion of the flexor pollicis longus or flexor digitorum profundus muscle located in the forearm which is considered an anatomical variant. The adequate knowledge regarding muscular variations is essential not only for anatomists but also for surgeons while approaching forearm for tendon transfer of flexor digitorum superficialis or anterior approach of elbow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
