Ulnar Artery Pseudo-Aneurysm in a Young Adult Male Due to Penetrating Trauma

Introduction: We present a young adult male who developed a proximal left ulnar artery pseudo-aneurysm that resulted from a penetrating stab wound after a period of 10years. Case Presentation: A 28years old male was referred to our facility with a history of an expanding left forearm swelling. He was initially diagnosed as a case of haematoma. A clinical diagnosis of pseudoaneurysm was confirmed by computed tomography angiography and resection done with ligation of the proximal ulnar artery and the distal branches. Conclusion: Proximal ulnar artery pseudo-aneurysm is very rare and may be associated with dire consequences in cases of delayed or missed diagnosis. Operative intervention remains the mainstay of treatment.
