Neurovascular rescue.

Neurovascular complications of carotid artery stenting (CAS) include intracranial embolism and hemorrhage, carotid dissection, in-stent thrombosis and vasospasm. Management of these crises requires knowledge of the intracranial vascular anatomy and collateral circulation, correct identification of the complication and its clinical implications, and a response plan that is appropriate to the complication and to the skill set of the operator. In this chapter the authors discuss techniques for the avoidance and management of CAS procedural complications.
