CLINICAL HISTORY A 32-year-old woman with migraine without aura, occurring on average two times per month since she was a teenager, was concerned about her risk of an aneurysm and requested evaluation. Her mother died at aged 58 years from a ruptured intracranial saccular aneurysm; there was no other relevant family history. I ordered an MRI scan of the brain with intracranial magnetic resonanc...

OBJECTIVE In this case report we describe a successful interdisciplinary approach (including flow redirection and endovascular occlusion) applied to a patient with a continuously growing extracranial giant aneurysm of the right internal carotid artery (ICA) due to known Ehlers-Danlos syndrome. CASE PRESENTATION A 42-year-old man with a continuously growing extracranial giant aneurysm of the r...

Treatment of bifurcation intracranial aneurysms is technically challenging. Sometimes it is necessary to pass a microcatheter through the aneurysm sac to navigate the microcatheter to a branch originating from the aneurysm sac. A 56-year-old male patient was treated for an incidental middle cerebral artery aneurysm. One branch originated from the medial part of the aneurysm sac, therefore stent...

A case of an intracranial arterial aneurysm at internal carotid bifurcation in a 10-year-old girl is described with the special features of cerebral aneurysm which occur in children, comparing with the adults. We alert for the necessity of carefully operative technique in order to avoid damage and intraoperative rupture of the aneurysm due to the very thin vessel wall that this population can d...

We report a case of middle cerebral artery (MCA) embolism accompanied by unruptured intracranial aneurysm in the same ischemic MCA territory, successfully treated with intravenous administration of recombinant tissue plasminogen activator (rt-PA). A 66-year-old right-handed man presented with abruptly decreased consciousness and right motor paralysis. He had a National Institute of Health Strok...

Concomitant occurrence of severe extracranial large vessel stenosis and an ipsilateral intracranial aneurysm is often detected incidentally, but the optimal therapeutic strategy is not clear. Several reports have investigated whether simultaneous carotid artery stenting and coil embolization, or multi-stage therapy is better. These treatment strategies are still controversial because simultaneo...

PURPOSE To assess the incidence of angiography-related rerupture of intracranial aneurysms and to analyze other risk factors of this complication. METHODS Clinical data from 144 patients with acute subarachnoid hemorrhage from ruptured intracranial aneurysm were reviewed retrospectively. In all patients, angiography was done by the transaortic approach. RESULTS The incidence of rerupture ca...

Intracranial aneurysms are a common and potentially devastating condition. They are found in approximately 1% of autopsies and 7% of patients referred for catheter angiography for indications other than subarachnoid hemorrhage1. Pathogenesis is not completely understood, but it is generally accepted that both genetic and hemodynamic factors play a role. As a group, a number of known heritable d...

SUMMARY Routine intensive care unit monitoring is common after elective embolization of unruptured intracranial aneurysms. In this series of 200 consecutive endovascular procedures for unruptured intracranial aneurysms, 65% of patients were triaged to routine (non-intensive care unit) floor care based on intraoperative findings, aneurysm morphology, and absence of major co-morbidities. Only 1 p...

Intracranial aneurysms are lesions commonly encountered by neurosurgeons, usually as a result of subarachnoid hemorrhage. The preferred treatment of these aneurysms is either surgical clipping or endovascular coiling, both of which eliminate the aneurysm from the normal circulation to prevent aneurysmal enlargement or additional hemorrhage. Despite advances over the last several decades in the ...
