Crimping technique to treat iatrogenic vertebral artery injury during spinal fusion

Iatrogenic arterial injuries may occur during neurosurgical procedures. Particularly, the vertebral artery may be injured in a high-level cervical spinal fusion case, either during the initial exposure or when placing screws.^{1- 3} If such an injury occurs, obtaining hemostatic control and repairing the laceration are of paramount importance.^{4, 5} In this technical video, we describe the case of a patient who was undergoing a posterior C1-C2 cervical fusion when the right vertebral artery was injured due to variant anatomy. Using sutures to repair the injury was unsuccessful. Thus, we employed a technique known as crimping, which involves the use of vascular clips to pinch off the site of the tear. This technique is an improvement over existing methods given how quickly and easily it can be performed. In our technical video, we explain how to perform the crimping technique and discuss indications for its use. The patient consented to the procedure.
