Morphologic variations of the superficial palmar arc

Anatomical variations of the superficial and deep palmar arches.

The use of radial arteries as an arterial bypass conduit is an invasive procedure which is becoming popular among various medical centres. The greatest risk associated with harvesting the radial artery is ischaemia of the soft tissues of the hand. In this study we dissected 200 hands derived from 100 formalin-fixed cadavers in order to identify arterial patterns that will allow safe removal of ...

The Incomplete Superficial Palmar Arch

INTRODUCTION Superficial palmar arch (SPA) is dominant vascular structure in palm of hand. In present study we described a case of Ulnar / Radiopalmar pattern of incomplete SPA in an Iranian cadaver. When the SPA is complete, the superficial palmer branches of the radial artery contribute to the ulnar artery. In incomplete type of SPA, there was no anastomosis between the ulnar and radial arter...

Bilateral incomplete superficial palmar arch

Introduction Superficial palmar arch (SPA) is the dominant vascular structure of the hand and is mainly formed by the anastomosis of ulnar artery (UA) with superficial branch of radial artery (RA), or arteria radialis indicis or arteria princeps pollicis from RA. A classical type of SPA is described as direct continuity between UA and superficial branch of RA confirms the presence of collateral...

Variations in the formation of superficial palmar arch and its clinical significance in hand surgeries

Subcutaneous superficial palmar arch – an unusual variant

Introduction Arterial arches of hand are the major blood supply to the structures in the hand. The two arches, superficial and deep palmar arches make an important anastomose between the radial and ulnar arteries. Superficial palmar arch (SPA) is formed by direct continuation of ulnar artery, i.e. superficial palmar branch, completed on lateral side by one of the three branches of radial artery...
