Bilateral Radial Artery Aneurysms Following Trauma: A Case Report.

Radial artery aneurysms are rare and are usually secondary to either blunt or penetrating traumatic etiology, such as catheterizations via radial artery access, bone fractures, or occupational injuries. Besides trauma, radial artery aneurysms may be related to idiopathic, infectious (mycotic), atherosclerotic etiology, or connective tissue diseases such as Marfan syndrome. However, bilateral radial artery aneurysms are extremely rare. A 61-year-old male developed pulsatile masses on both wrists following syncopal episodes that led to falls. Imaging confirmed bilateral radial artery aneurysms. The patient underwent surgical resection of both aneurysms - first on the right wrist, followed by the left after cellulitis resolution. Her postoperative course was uneventful. Histopathological examination showed findings suggestive of the true aneurysm. This rare case underscores the importance of early diagnosis and surgical intervention for bilateral radial artery aneurysms, particularly following trauma.
