Initially, the patient presented with ischemic symptoms in the right small finger and underwent successful surgical debridement of the radial and ulnar arteries. Subsequently, the patient suffered a cardiac arrest five weeks postoperatively and underwent radial arterial line placement, which led to worsening vascular symptoms in the affected extremity. A second surgery revealed a diagnosis of mycotic aneurysm of the distal ulnar artery. The diseased artery was resected and reconstructed using vein grafts. Following reconstruction, the patient recovered with restored perfusion and resolution of pain. This case highlights the clinical course of diagnosing upper limb mycotic aneurysm and reconstruction of upper limb arteries, stressing the importance of clinical suspicion and timely surgical intervention.  \nRésumé  \nLes auteurs présentent le rapport d’une rare occurrence d’anévrisme mycotique des membres supérieurs chez un homme de 36 ans présentant de multiples morbidités connexes, y compris un diabète, une insuffisance rénale terminale et des infections antérieures. Au départ, le patient a consulté à cause de symptômes ischémiques dans l’auriculaire droit et subi undébridement chirurgical réussi des artères radiale et cubitale. Il a été victime d’un arrêt cardiaque cinq semaines aprèsl’opération et s’est fait installer un cathéter radial, qui a aggravé les symptômes vasculaires de la main atteinte. Une deuxième opération a révélé un diagnostic d’anévrisme mycotique de l’artère cubitale distale. L’artère atteinte a été réséquée et reconstruite par des greffes veineuses. Après la reconstruction, la perfusion a repris et la douleur s’est résolue. Ce cas fait ressortirl’évolution clinique nécessaire pour diagnostiquer un anévrisme mycotique des membres et procéder à une reconstruction des artères des membres supérieurs, ce qui démontre l’importance des soupçons cliniques et d’une intervention chirurgicale rapide.  \nKeywords  \nMycotic aneurysm, hand ischemia, limb salvage, vein graft, radial artery, ulnar artery, vascular reconstruction  \n1 Division of Plastic and Reconstructive Surgery, University of Calgary, Calgary, Canada  \n2 Faculty of Medicine, University of Ottawa, Ottawa, Canada Received October 30, 2025.
