Carotid Artery Dissection and Ischemic Stroke Following Cervical Chiropractic Manipulation: Two Case Reports

Objective Patients can be at risk of carotid artery dissection and ischemic stroke after cervical chiropractic manipulation. However, such risks are rarely reported and raising awareness can increase the safety of chiropractic manipulations. Case Report We present two middle-aged patients with carotid artery dissection leading to ischemic stroke after receiving chiropractic manipulation in Foshan, Guangdong Province, China. Both patients had new-onset pain in their necks after receiving chiropractic manipulations. Excess physical force during chiropractic manipulation may present a risk to patients. Patient was administered with recombinant tissue plasminogen activator after radiological diagnoses. They were prescribed 100 mg and clopidogrel 75 mg daily for 3 months as dual antiplatelet therapy. There were no complications over the follow-up period. Conclusion These cases suggest that dissection of the carotid artery can occur as the result of chiropractic manipulations. Patients should be diagnosed and treated early to achieve positive outcomes. The safety of chiropractic manipulations should be increased by raising awareness about the potential risks.
