Superficial ulnar artery terminating in a normal ulnar artery

Abstract

Routine dissection of the left upper limb of an 86-year-old male cadaver showed a superficial ulnar artery that anastomosed with the ulnar artery. The superficial ulnar artery arose from the third part of the axillary artery, coursed distally over the flexor muscles of the forearm, and terminated by anastomosing with the ulnar artery in the distal third of the forearm. Arterial and neural variations were also observed on the contralateral side. The presence of a superficial ulnar artery is important clinically when raising forearm flaps in reconstructive surgery.

Arteria Ulnar Superficial, Bilateral y Antebraquial. Similitudes y Diferencias

“…Ambas AUS muestran tortuosidades, descritas previamente (Mannan et al;Solan;Rodrigues et al, 2016) pero con morfología diferente a nuestros hallazgos, sin establecer la causa de la deformación, siendo interpretadas como deficiencias del tejido conectivo. Las tortuosidades del primer segmento en ambos casos son similares en morfología y extensión, con ligera oblicuidad la del antebrazo derecho.…”

“…El origen de la AUS ha sido reportado en la arteria axilar (AA) (Dubreuil Chambardel, 1926;Singer, 1933;Weathersby, 1956;Fadel & Amonoo-Kuofi, 1996;Jacquemin et al, 2001;Natsis et al, 2006;Mannan et al, 2008;Yadav et al, 2013); en la arteria braquial (AB) en el brazo (Hazlett, 1949;Weathersby;Blagojka, 1982;del Sol et al, 2000;Rodríguez-Niedenführ et al, 2001;Natsis et al;Dartnell et al, 2007;Senanayake et al, 2007;Troupis et al, 2011;Casal et al, 2012;Solan, 2013;Salunke et al, 2014;Abhinita et al, 2016) o en la fosa cubital (Hazlet; Weathersby;Blagojka;Panicker et al, 2003;Shetty et al, 2013;Yadav et al;Kusztal et al, 2014;Kumka & Purkiss, 2015;Quadros et al, 2015;Sirasanagandla et al, 2016). En nuestro caso, los hallazgos remiten a este último origen y al trayecto en el antebrazo de ambas arterias.…”

Superficial brachioulnar artery in man

“…Since the SBUA usually arches and overlies the antebrachial fascia it may inadvertently be mistaken for either a superficial antebrachial vein or superficial phlebitis, and so be injured by presumptive venipuncture [9,11,15,25,26,30]. Such a large subcutaneous artery in the forearm is prone to unwanted injury and brings an elevated risk of bleeding complications in unexpected situations [3,5,6,9,11,13,14].…”
