The PMA coexisted with a bilateral bifid median nerve (MN) and two bilateral interconnections (ICs characterized with the symbol -) of the MN with the ulnar nerve (UN) (MN-UN) and a unilateral reverse IC (UN-MN). Emphasis was given to the artery\u2019s developmental background.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The PMA was identified in an 80-year-old formalin-embalmed donated male cadaver.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The right-sided PMA terminated at the wrist, posterior to the palmar aponeurosis. Two neural ICs were identified: the UN joined the MN deep branch (UN-MN), at the forearm\u2019s upper third, and the MN deep stem joined the UN palmar branch (MN-UN), at the lower third (9.7\u00a0cm distally to the 1st IC). The left-sided PMA ended in the palm giving off the 3rd and 4th proper palmar digital arteries. An incomplete superficial palmar arch was identified by the contribution of the PMA, radial, and ulnar arteries. After the MN bifurcation into superficial and deep branches, the deep branches formed a loop, that was penetrated by the PMA. The MN deep branch communicated with the UN palmar branch (MN-UN).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The PMA should be evaluated as a causative factor of carpal tunnel syndrome. The modified Allen's test and the Doppler ultrasound may detect the arterial flow and the angiography may depict the vessel thrombosis in complex cases. PMA could also be a \"salvage\" vessel for the hand supply, in radial and ulnar artery trauma.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00276-023-03183-y","type":"journal-article","created":{"date-parts":[[2023,6,27]],"date-time":"2023-06-27T06:02:57Z","timestamp":1687845777000},"page":"1097-1102","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Median artery persistence in coexistence with a bifid median nerve and interconnections of the median with the ulnar nerve and vice versa"],"prefix":"10.1007","volume":"45","author":[{"given":"Maria","family":"Piagkou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Tsakotos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Triantafyllou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christos","family":"Koutserimpas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Trifon","family":"Totlis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasilios","family":"Karampelias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantinos","family":"Natsis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,6,27]]},"reference":[{"issue":"3","key":"3183_CR1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.CC.19.00468","volume":"10","author":"A Dhal","year":"2020","unstructured":"Dhal A, Prakash S, Kalra P, Khan Y (2020) Unusual triad of bifid median nerve, persistent median artery, and aberrant muscle causing carpal tunnel syndrome: a case report.
