Abstract:
OBJECTIVE AND IMPORTANCE:Intraoperative aneurysmal rupture represents a potentially catastrophic event. We describe the use of an intravenous adenosine bolus to induce transient cardiac asystole to control a severe intraoperative aneurysmal rupture. This treatment resulted in a brief period of severe hypotension, which enabled successful clipping of the aneurysm. CLINICAL PRESENTATION:A 55-year-old man was referred to our institution 7 days after experiencing a mild subarachnoid hemorrhage from a fusiform, multilobulated aneurysm of the anterior communicating artery. The patient was found to have multiple additional fusiform aneurysms as well as a large parietal arteriovenous malformation. INTERVENTION:A craniotomy was performed to clip the aneurysm, but surgical dissection was complicated by premature rebleeding that could not be controlled satisfactorily with tamponade or temporary arterial occlusion. Infusion of adenosine resulted in the rapid onset of profound hypotension, allowing for safe completion of the dissection and clipping of the aneurysm with a good outcome. There were no complications identified in relation to the use of adenosine. CONCLUSION:In the setting of severe intraoperative aneurysmal rupture, intravenous adenosine represents a potential means of achieving a near-immediate profound decrease in the blood pressure that may allow for safe completion of the dissection and aneurysm clipping.
