Ventricular Tachycardia During Neurointerventional Procedures-A Rare Complication

Abstract Anesthesiologists play a critical role in ensuring hemodynamic stability and managing potential complications during neurointerventional procedures. Complications during neurointerventions could be hemorrhagic (aneurysm perforation, intracranial vessel injury, dissection) or occlusive (thromboembolic, vasospasm), contrast related, etc. [1] Cardiac events during neurointerventions are rare but could be catastrophic. Sensitization and readiness of anesthesiologist for such events certainly help to improve patient outcome. The complex bidirectional interaction between brain and heart is well explained in the literature and trigeminocardiac reflex (TCR) is very common example of this.[2] TCR is well studied during neurosurgeries, but it’s occurrence during neurointerventions should not be denied. The spectrum of cardiac events during TCR includes bradyarrythmias, hypotension, hypertension, tachyarrhythmias.[3] Cushing's reflex (bradycardia, hypertension, irregular breathing) can be caused by ruptured intracranial aneurysms/ arteriovenous malformation/ dural arteriovenous fistula. Stimulation of stretch receptors in major vessels during catheter manipulation, onyx embolization in cardiac/ pulmonary circulation can also result in arrhythmias during neurointerventions.[4] Here we came across two different cases. In the first case, a 25-year-old female developed ventricular tachycardia after embolization of dural arteriovenous fistula (DAVF), which spontaneously reverted to normal sinus rhythm. In the second case, a 34-year-old male experienced ventricular tachycardia during catheter manipulation, which resolved after catheter withdrawal.
