“…The median artery is also involved in the formation of the superficial palmar arch with a low frequency in adults. The persistent existence of the median artery in the palm was found to be approximately 8% in Japanese cadavers, as determined by gross anatomy (Adachi, 1928; Kodama, 2000), although the incidence of the persistent median artery in the hand has also been reported by other authors (Table 1; Jaschtschinski, 1897; Tandler, 1897; Gray, 1945; McCormack et al ., 1953; Weathersby, 1954; Coleman & Anson, 1961; Keen, 1961; Braun et al ., 1979; Valdecasas Huelin et al ., 1979; Karlsson & Niechajev, 1982; Libersa et al ., 1982; Ebner & Hammer, 1988; Ikeda et al ., 1988; Jelicic et al ., 1988; Maher, 1990; Srivastava & Pande, 1990; Henneberg & George, 1992; Kopuz et al ., 1995; Kopuz et al ., 1997; Olave et al ., 1997; Rodriguez‐Niedenführ et al ., 1999, 2001; Fazan et al ., 2004). Table 1 lists the reports about the median artery in the hand, in which most of the methods used gross anatomy although some also used angiography or histology.…”

Persistent median artery in the hand: A report with a brief review of the literature

et al. 2006

We encountered a persistent median artery in the forearms and hands bilaterally in a 78-year-old Japanese male cadaver during dissection practice at Wakayama Medical University. The brachial arteries divided into the ulnar and radial arteries. The ulnar artery gave off the median and posterior interosseous arteries at the same point, although the anterior interosseous artery was not found. The median artery ran along the median nerve and bifurcated in the hand. In the superficial layer of the palm, one branch of the median artery ran to the ulnar side of the thumb, whereas the other passed to the second interdigital space. The ulnar artery reached the third and fourth interdigital spaces and the ulnar side of the little finger, and showed no anastomosis with the median artery in the superficial layer of the palm. The radial artery did not give off the superficial palmar branch. Therefore, the formation of the superficial palmar arch was incomplete. In the deep layer of the palm, the radial artery formed the deep palmar arch with the deep palmar branch of the ulnar artery and gave off the princeps pollicis artery. In the dorsum of hand, the radial artery passed over the first dorsal interosseous muscle to the index finger and communicated with the palmar pollical artery from the median artery in the first interosseous space. The present study reports an unusual variation of the persistent median artery in the hand and briefly reviews the literature about the median artery.

“…Set 2 included the prevalences of persistent median arteries of the forearms presented in set 1, after excluding those obtained from foetuses (Aragão et al, 2017), and from studies that were limited only to hands (Tandler, 1896;Jaschtschinski, 1897;Barbosa Sueiro, 1916;Smanio, 1941;Weathersby, 1954;Coleman & Anson 1961;Kenesi et al, 1967;Chalmers, 1978;Braun et al, 1979;Ebner & Hammer 1988;Jelicic 1988;Olave et al, 1997;Gellman et al, 2001;Fazan et al, 2004;Barbe et al, 2005;Loukas et al, 2005;Bilge et al, 2006;Agarwal et al, 2014;Joshi et al, 2014; i.e. the palmar phenotype).…”

Recently increased prevalence of the human median artery of the forearm: A microevolutionary change

2020

The median artery has been considered as an embryonic structure, which normally regresses around the 8th week of gestation. However, various prevalences have been reported in adults since the 18th century. Furthermore, in a study by Henneberg and George (1995; Am J Phys Anthropol 96, 329–334), has suggested that increasing prevalence of the median artery during the 20th century was a ‘possible secular trend’. The present study, conducted nearly a quarter of a century later, is a continuation of that study. A total of 26 median arteries were found in 78 upper limbs obtained from Australians aged 51 to 101 years, who died in the period 2015–2016, a prevalence rate of 33.3%. Analysis of the literature showed that the presence of the median artery has been significantly increasing (p = .001) over time, from approximately 10% in people born in the mid‐1880s to approximately 30% by the end of the 20th century. The significance of the prevalence increased to a p value <.0001, when the results of the present study and other studies conducted by our research team were combined. After removal of the studies that were possibly biased, because of their specific focus on the evolutionary aspects of the median artery, the significance remained at p = .018. The present study provides an example of microevolutionary changes in the internal anatomy of the human body. Second‐order polynomial regression of the median artery's prevalence on dates of birth shows that it is now present in 35% of people and predicts that people born 80 years from now will all carry a median artery if the trend continues. When the median artery prevalence reaches 50% or more, it should not be considered as a variant, but as a ‘normal’ human structure.

“…Sometimes there is also participation of the median a. [1,2,4,6,11,12,14,15]. It has been reported that any increase of median a. caliber, due to thrombosis, aneurysm or simply of congenital origin, may cause median n. compression in the carpal tunnel [3,7,10,13].…”

Abnormal course of the superficial palmar branch of the radial artery

et al. 1996

The structures in the carpal tunnel are the flexor muscle tendons and their sheaths and the median n. Due to the inflexibility of its walls, any swelling of its contents that produces decrease of its volume, may compress the median n. There are many possible causes of nerve compression, such as the presence of arteries in this tunnel [3, 13]. The carpal tunnels of 70 hands of 35 adult cadavers of both sexes, whose age ranged from 23 to 77 years, were studied by dissection. An abnormal course of the superficial palmar branch of the radial a. was found in 2 hands (2.85%). This vascular branch passed through the carpal tunnel. This unusual course of the superficial palmar branch of the radial a. is described with details correlating its presence in the carpal tunnel with the median n.
