Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 1
Abstract
Background: Knowledge of the variations in the arterial supply of hand has reached a point of practical importance with the advent of microvascular surgery for revascularization, replantation, and composite tissue transfers. Superficial palmar arch (SPA) hasmany interesting variations, of them, the median artery (MA) contribution is been evaluated in this study. Materials and Methods: Present study was conducted on 40 adults upper limbs of unknown sex. All the specimens were obtained from the Anatomy Departments of Government Medical College and Hospital, Chandigarh, India. Results: In this study, 7.5%of specimens showed median–ulnar type of incomplete SPA. Conclusion: The clinical importance of the persistence of this artery at wrist level is well documented as a cause of the carpal tunnel syndrome but it has also been associated with the “pronator teressyndrome” in cases where the persistent MA pierces the median nerve in the proximal third of the forearm.
