Internal carotid artery dissection in a patient with Parkinson's disease after COVID-19 infection

Internal carotid artery (ICA) dissection is a relatively rare cause of acute ischemic stroke. Stretching and compression of ICA due to sudden acceleration, deceleration, and rotational forces are risk factors for ICA dissection. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to trigger an inflammatory response that exacerbates endothelial dysfunction and leads to arterial dissection. Although levodopa-induced cervical dyskinesia in Parkinson's disease often manifests as choreiform movement, dissection has not been reported in such patients.
