RESUMO
Most aneurysms can be effectively managed using endovascular coiling or microsurgical clipping, but in an acute subarachnoid haemorrhage where there are multiple aneurysms identified, a sequential multimodal approach may prove more beneficial. This report involves a 31-year-old man who presented with sudden onset of severe headache and photophobia. A computed tomography brain scan revealed a diffuse grade II subarachnoid haemorrhagic pattern, and four-vessel angiography revealed two aneurysms: a right middle cerebral artery bifurcation aneurysm measuring 12 x 8 mm and a 4-mm basilar artery aneurysm associated with a fenestration at the confluence of the vertebral arteries. It was not possible to determine which aneurysm or aneurysms were responsible for the haemorrhage using the customary criteria. The patient underwent sequential endovascular coiling of the vertebrobasilar aneurysm without delay, followed immediately by microsurgical clipping of the right middle cerebral artery aneurysm, under a single anaesthetic. The postoperative course was uneventful. This method is a treatment option for acute subarachnoid haemorrhage where there are multiple aneurysms. It is a logical progression of management that could be employed at any experienced neurovascular centre; the employment of a sequential multimodal approach from the integration of these techniques is beneficial to the patient because it decreases morbidity and mortality.
