A Case of Bilateral Superficial Ulnar Artery Variation
(Düzce Üniversitesi, 2014) Bakırcı, Sinan; Kafa, İlker Mustafa; Uysal, Murat; Şendemir, Erdoğan
During routine dissection of a 60- 65 years old Caucasian, male cadaver, we found that the ulnarartery is coursing superficially on both forearms. These superficial ulnar arteries (SUA) wereoriginating 2 cm above from termination of the brachial arteries and were running superficiallyto the flexor muscles in forearm. The brachial artery was terminated in the cubital fossa anddivided as radial, common interosseal and recurrent radial arteries. Variations of arteries, muscles and nerves of the upper limb are well documented. Variations ofthe radial artery is most frequent arterial anomaly of the forearm (15,6%), whereas theprevalence of the superficial ulnar artery is less frequent and given as the percentage of 0.7-9.4.Furthermore, its bilateral prevalence is very rare (0.01-0.62%). If it is present, the superficialulnar artery is vulnerable to traumas which may be a cause of hemorrhage and it may be riskfor misguided intra-arterial injections that may be a cause of ischemia, even non-reversiblenecrosis and gangrene in the distal portion of the forearm. Additionally, SUA may be valuablefor arterial cannulations and harvesting fasciocutaneous forearm flaps
