“…A similar disposition to ours is mentioned by Hashem et al [12], without indicating which metacarpal artery is substituted. Occasionally a second palmar metacarpal artery (2PMA) can supply a CPDA of the second space [2], forming another anastomosis between elements of the DPA and the SPA [3,4]. Coleman and Anson [7] say that the most developed artery destined for thumb should be called 1PMA.…”

“…Although the incidence of modifications in arterial disposition is low, occlusions of the RA due to cannulation or trauma (Mozersky cited by Parks [18]) may have consequences such as ischaemia or acute vascular insufficiency of the thumb. We believe that caution must be exercised in surgical approaches to the radial side of the hand, where arterial variations are more frequent [4,5], for example in aponeurotic retractions, lesions of the flexor tendons of the index, and in primary or secondary repairs. There is also a risk in the pollicisation of the index finger [12].…”

“…Diversifications in the development of superficial palmar arch are common. In addition to diversity in superficial palmar arch, there is also diversification in branches of the radial artery supplying the superficial palmar arch and arterial supply of the index finger and the thumb (Bianchi, 2001;Gellmann et al, 2001;Madhyastha et al, 2011). Allen's and modified Allen's test, Color doppler ultrasonography, Upper limb arteriography, oxygen saturation by pulse oximeter can accordingly be opted in order to appraise the effictiveness of collateral arterial flow prior to surgical interventions.…”

Human hand is highly evolved in terms of complexity and variations. In this modern medical era, vascular anatomy of the human hand has clinical importance in medical, surgical and radiological sciences. The intention of the current study is to determine the variations which occur as the radial artery branches thus making a contribution to the arterial supply of the index finger and the thumb. The study design was descriptive case series, carried out in the Department of Anatomy in King Edward Medical University from December 2018 to May 2019 on 30 cadaveric limbs. Vivisection of the cadaveric hands was performed following Cunningham’s Manual of practical anatomy. The origin and the course of RA, UA and MA were dissected and identified with further exploration of the blood supply of the index finger and the thumb. All details were entered in a predesigned proforma, and the dissected limbs were photographed. Data was analyzed to find the frequencies of superficial palmar arch as well as the arterial supply of thumb and index finger were also expressed in frequencies. Great variation was observed in the arterial supply to palmar aspect of index finger and thumb. Main contributing artery being radial artery in majority of cases through its common palmar or proper palmar branches arising from SPA or SPBRA. Ulnar artery and median artery were also observed to be supplying these areas in 6.6% and 3.3% cases respectively. The median artery when present was replacing the radial artery on palmar aspect of hand. The dorsum, however, was supplied by the princeps pollicis and the radialis indicis branches of radial artery in all the cases. We concluded that in about 1/3rd (11/30 are incomplete SPA) of our studied sample, arterial supply of the index finger and the thumb is highly dependent on radial artery and should any damage occur to it, vitality of these useful structures will be compromised.

“…Éstos arcos arteriales están conformados más frecuentemente por las arterias ulnar y radial estableciendo un patrón descripto como clásico; siendo el arco palmar superficial conformado por la terminación de la arteria ulnar y por la rama radio-palmar (pal-III Cátedra de Anatomía, Facultad de Medicina, Universidad de Buenos Aires, Buenos Aires, Argentina. mar superficial) de la arteria radial, y sus ramas incluyen cuatro arterias digitales palmares comunes, de las cuales se derivan las arterias digitales palmares propias (Bianchi, 2001;Gellman et al, 2001;Elizondo-Omaña et al, 2007;Drake et al, 2010;Umapathy et al, 2012;Arias-Hernández et al, 2015) y el arco palmar profundo conformado por la arteria radial y la rama (palmar profunda) de la arteria ulnar, siendo sus ramas una recurrente que se anastomosa con el arco dorsal del carpo, unas ramas perforantes que atraviesan los espacios intermetacarpianos para unirse a las arterias dorsales del metacarpo, y tres arterias metacarpianas palmares, las cuales pueden perforar a los músculos interóseos para unirse en algunos casos a las arterias digitales palmares comunes del arco palmar superficial antes de su bifurcación (Pansky, 1996). Se describen variaciones anatómicas en la conformación de ambos arcos, mas frecuentemente en el arco palmar superficial; pudiendo ser los mismos completos o incompletos (Lippert & Pabst, 1985;Bianchi).…”

The irrigation of the palm is provided by arterial arches (shallow and deep) that are made more frequently by the ulnar or radial arteries described as setting a classic pattern. Anatomical variations are described in shaping both arches, most often in the superficial palmar arch; may be the same complete or incomplete. The objective of this work is the anatomical description of the palmar arches, their different patterns and variations in conformation, and their clinical and surgical implications. A descriptive, observational and morphometric study of the arteries involved in the formation of the palmar arches was done in the Faculty of Medicine, University of Buenos Aires. One hundred1(00) cadaveric preparations fixed in formalin solution, of the Third Chair of Anatomy were used. A retrospective analysis of cases with lesions / s artery / main / s that make the palmar arches in the Emergency Hospital of Moron, between 2015-2016 s was also carried out. Most frequently the radial artery forms the deep palmar arch with the deep palmar branch of the ulnar artery. Superficial palmar arch is the most variable. It was complete in 56 % and the most common presentation (83 %) is one that is formed by the anastomosis of the ulnar artery and the superficial palmar branch of the radial artery. The rest of the anastomosis are between ulnar artery and median artery (9%), between deep branch of radial artery and ulnar artery (5 %); triple anastomosis between ulnar artery, median artery and superficial palmar branch of the radial artery (2 %), and anastomosis between the median artery and superficial palmar branch of the radial artery without participation of the ulnar artery (1 %). The rest of the sample (44 %) can be termed as incomplete. The B1a and B1b subtypes were the most found. Two cases, one entire section of the radial artery at the wrist and the other with complete section of ulnar artery with involvement of the ulnar nerve are described. It is essential to a proper understanding of the palmar arches for a suitable surgical approach to hand. The importance of the presence or absence, as well as different variations of palmar arterial arch lies in its clinical application as surgical starting point in the treatment of trauma and other diseases in which there is engagement of arteries.
