We report a case of simultaneous microsurgical clipping 5 cerebral aneurysms in patient with multiple the anterior brain.We analyzed existing treatment approaches to aneurysms, including endovascular isolation, clipping, as well surgical tactics subarachnoid hemorrhage. covered recommendations for screening, risks, and aneurysm isolation (single-stage multiple-stage).Using our own experience (s...

BACKGROUND AND PURPOSE In clinical practice, durability of occlusion following coil embolization is superior in densely packed, compared with loosely packed, aneurysms. In a rabbit model, we probed, by using proteomics tools, the biologic mechanisms associated with densely packed and completely occluded aneurysms, compared with loosely packed and incompletely occluded aneurysms, to explore the ...

OBJECTIVE To determine the prevalence of early branch aneurysms, characterize these lesions angiographically and anatomically, and determine their clinical significance. METHODS The authors conducted a retrospective review of 125 consecutive patients with a diagnosis of middle cerebral artery (MCA) aneurysm. Eighty-four patients harboring 100 MCA aneurysms were studied; 41 patients were exclu...

BACKGROUND AND PURPOSE To report morbidity, mortality, and angiographic results of elective coiling of unruptured intracranial aneurysms. METHODS In a 10-year period, 176 unruptured aneurysms in 149 patients were electively treated with detachable coils. Seventy-nine aneurysms were additional to another ruptured aneurysm but were coiled more than 3 months after subarachnoid hemorrhage, 59 ane...

OBJECTIVE To review the pattern of ruptured intracranial aneurysms in terms of size, location, and the prevalence of multiple aneurysms in the Hong Kong Chinese population with subarachnoid haemorrhage. DESIGN Retrospective study. SETTING Three public hospitals in Hong Kong. PATIENTS A total of 267 Chinese patients with subarachnoid haemorrhage from ruptured intracranial aneurysms between...

Development of less invasive imaging studies, such as magnetic resonance angiography, has increased the chances that unruptured cerebral aneurysms are found. The rupture risk of "symptomatic" aneurysms is higher than for "asymptomatic" aneurysms; so "symptomatic" aneurysms are more often surgically treated. Many reviews examine "asymptomatic" unruptured cerebral aneurysms, but few evaluate "sym...

Background and Purpose—The strategy of treatment of small unruptured intracranial aneurysms is complex because of their presumably low risk of rupture. A precise knowledge of the perioperative complications in this specific subgroup is mandatory. The purpose of this study was to compare the results of the endovascular treatment of aneurysms 3 mm and aneurysms 3 mm included in the Analysis of Tr...

Background and Purpose—The natural history and optimal management of incidentally found small unruptured aneurysms 5 mm in size remain unclear. A prospective study was conducted to determine the optimal management for incidentally found small unruptured aneurysms. Methods—From September 2000 to January, 2004, 540 aneurysms (446 patients) were registered. Four hundred forty-eight unruptured aneu...

BACKGROUND AND PURPOSE Paraclinoid aneurysms have been increasingly treated endovascularly. The natural history of these aneurysms has gradually been elucidated. The purpose of this study was to assess the safety and efficacy of endovascular treatment for these aneurysms. MATERIALS AND METHODS We performed a retrospective review of 377 patients with 400 paraclinoid aneurysms treated between J...

Background and Purpose—Patients with a history of aneurysmal subarachnoid hemorrhage may have aneurysms on screening several years after the hemorrhage. For determining the benefits of follow-up screening, it is important to know whether these aneurysms have developed after the hemorrhage or are visible in retrospect, and if so, whether the size has increased. Methods—Aneurysms were categorized...
