An acutely ischaemic hand in a young adult due to subclavian artery aneurysm (SAA) caused by a cervical rib: A case report.

INTRODUCTION: True subclavian artery aneurysms are relatively rare lesions. Thoracic outlet compression is responsible for 75% of aneurysms. They are formed as a result of compression by, for example a cervical rib. CASE PRESENTATION: We present a case of subclavian artery aneurysm secondary to a cervical rib in a 25-year-old young Asian adult, who presented with an acutely ischaemic upper limb. A Computed Tomography angiogram revealed a right sided cervical rib and sacular aneurysm in the mid-portion of the subclavian artery. CONCLUSION: Although it is a rare condition, it is important to be aware especially in the young age group. Surgical management has very favourable outcomes in these patients.
