A 21-year-old patient presented with sudden-onset headache, visual disturbance and left hand incoordination. She was diagnosed with a left vertebral artery dissection of the V3 segment resulting in multiple cerebellar and cerebral infarcts. There were no risk factors for dissection other than recent COVID-19 infection. She was treated initially with antiplatelets, followed by anticoagulation, but experienced recurrent ischaemia. Although guidance suggests endovascular repair may be beneficial for patients with cerebral artery dissection (CAD) who experience recurrent strokes on medical therapy, evidence is limited. After multidisciplinary team consideration of the individual patient anatomy and risks and benefits of different endovascular techniques, the patient was treated with endovascular coiling. At 10 months follow-up, she had no further strokes and improving neurological symptoms. The case highlighted COVID-19 as a potential trigger for CAD and the use of endovascular coiling in preventing catastrophic cerebral ischaemia in CAD refractive to medical therapy.
