Internal carotid artery pseudoaneurysm after neck manipulation in a patient with Eagle syndrome

Contraindications of spinal manipulative therapy (SMT) have been proposed, which mandate rigorous control for its safe practice when manipulating the upper spine. Here, we report a vascular complication of Neck Manipulation in Eagle syndrome (ES) patient.

SMT is used to treat musculoskeletal conditions such as back pain and neck pain by applying force to the spinal joints. Here, we report a rare but devastating complication of SMT, where a young male patient, 22 years old, with ES, had a large pseudoaneurysm from the internal carotid artery (ICA) after SMT from an unlicensed practitioner, treated successfully with endograft. Clinicians administering SMT should consider an elongated styloid process as a potential contraindication to this therapy.
