An Anatomical Study of Superficial Palmar Arch and its Clinical Significance

Kalaiselvi .C ^[3] | Girijakumari .K ^[3]

Abstract: Background: Superficial palmar arterial arch is a dominant vascular structure of the palm. It is defined asan arterial arcade, formed by superficial branch of the ulnar artery and completed on lateral side by the superficial palmar branch of the radial artery or Arteria radialis indicis or Arteria princeps pollicis or arteria nervimediana. Variations can occur in the vessels contributing to the formation of superficial palmar arch (SPA). Aim: The main objective of the study is to know the formation of superficial palmar arch and different types of formation with an emphasis on its clinical relevance. Result: The present study was conducted on 50 specimens, followingthe classification of Coleman and Anson. We found complete arch of type A in 43 hands (86%) and of type B in 3 hands (6%). In this study incomplete arch was seen in 4 hands (8%, 1 right and 3 left), persistent median artery type H supplying the radial side of the palm and digits was seen in only one hand (2%). Conclusion: Knowledge of such variations is of immense help for microvascular surgeons, plastic surgeons and orthopaedicians to bring a better outcome in their surgical procedures. Also, it will be helpful for cardiovascular surgeons to carryout radial artery harvesting procedures for the purpose of Coronary Artery Bypass Grafting.
