Anesthesia and intracranial arteriovenous malformation release_5nm73pkuijcixopbtvtozaksra

Abstract

Anesthetic management of intracranial arteriovenous malformation (AVM) poses multiple challenges to the anesthesiologist in view of its complex and poorly understood pathophysiology and multiple modalities for its treatment involving different sub-specialties. The diagnosis of AVM is based on clinical presentation as well as radiological investigation. Pregnant patients with intracranial AVM and neonates with vein of Galen malformation may also pose a special challenge and require close attention. Despite technological advancement, reported morbidity or mortality after AVM treatment remains high and largely depends on age of the patient, recruitment of perforating vessels, its size, location in the brain, history of previous bleed and post-treatment hyperemic complication. Anesthetic management includes a thorough preoperative visit with meticulous planning based on different modalities of treatment including anesthesia for radiological investigation. Proper attention should be directed while transporting the patient for the procedure. Protection of the airway, adequate monitoring, and maintaining neurological and cardiovascular stability, and the patient's immobility during the radiological procedures, appreciation and management of various complications that can occur during and after the procedure and meticulous ICU management is essential.
