A Case Report on Superficial Palmar Arch Formed Alone by Ulnar Artery

Abstract

The present study reporting a variation of superficial palmar arch which is formed alone by superficial branch of ulnar artery and it is also giving branches to radial side of index finger and to the thumb. Normally the branch to the radial side of index finger receives branch from superficial terminal branch of radial artery and it is known as arteria radiclis indicis. A dominant vascular structure of the palm is the superficial palmar arterial arch, also known as an arterial arcade. The superficial palmar branch of the radial artery and the superficial branch of the ulnar artery are anastomosed together. By anastomosing with one of the radial artery's branches, such as the arteria radialis indicis, arteria princeps pollicis, or arteria nervi mediana, the superficial palmar arch is completed. The ARI was given by ulnar artery from the terminal part of radial side along with the princeps pollicis branch. The knowledge of variations of the vascular arches warrants the surgeons while performing surgeries on hands, such as arterial repairs, vascular graft applications. Understanding the variations of the arterial arch patterns of the hand is critical for performing safe surgical procedures on the hand. Surgeons should be aware of this type of variation when performing surgical interventions for arerial repairs and vascular graft applications, because the SPA plays an important role in the majority of traumatic conditions and surgical procedures.
