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.
