The anatomy of the palmar vascular arches is a complex and challenging area. Understanding the vascular patterns of the hand and their variations is very important for surgeons, radiologists and anatomists because of innovative microsurgical techniques in reconstruction of a traumatized hand, and may be useful for graft surgeries, when the arteries of the upper limb are used for coronary artery bypass. The description of a complete arch refers to the existance of an anastomosis between the superficial palmar branches of ulnar and radial arteries, or in cases in which the ulnar artery alone supplies all the fingers an the ulnar side of the thumb. An incomplete arch was defined when it only supplies the 5th, 4th, and 3rd digits. We evaluated 36 hands belonging to 19 formalin preserved cadavers to determined the pattern of the superficial palmar arch, its branches, and contributing vessels. We discard two specimen. The ulnar artery was injected with red colored latex. In addition to the frequently encountered types of superficial palmar arch, a myriad of very rare cases in which the princeps pollicis and radialis indicis arteries arising from the first and second dorsal metacarpal arteries, and from a voluminous superficial palmar branch of radial artery. In other cases the palmar metacarpal arteries gave origin to the common palmar digital arteries.
