Unruptured intracranial aneurysms: natural history, clinical outcome, and risks of surgical and endovascular treatment.
BACKGROUND The management of unruptured intracranial aneurysms is controversial. Investigators from the International Study of Unruptured Intracranial Aneurysms aimed to assess the natural history of unruptured intracranial aneurysms and to measure the risk associated with their repair. METHODS Centres in the USA, Canada, and Europe enrolled patients for prospective assessment of unruptured a...
متن کاملSymptomatic unruptured cerebral aneurysms: features and surgical outcome.
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...
متن کاملDefining the natural history of unruptured aneurysms.
Despite advances in neurosurgical technique, neuroanesthesia, and neurocritical care and the evolution of endovascular therapy, aneurysmal subarachnoid hemorrhage (SAH) continues to be associated with poor outcome in a majority of patients. The 30-day mortality rate for SAH approaches 50%,1,2 and nearly one half of survivors suffer major neurologic morbidity. These dismal outcomes are especiall...
متن کاملSurgical treatment of unruptured cerebral aneurysms in the elderly.
We retrospectively analyzed the prevalence and surgical outcomes of unruptured cerebral aneurysms in the elderly for the past five years. Between 1998 and 2002, we collected data from 575 subjects with unruptured aneurysms who had no history of subarachnoid hemorrhage (SAH). One hundred and eighty-two of these patients (31.7%) were aged > or = 70 years and they had 233 aneurysms. The proportion...
متن کاملNatural history, epidemiology and screening of unruptured intracranial aneurysms.
The prevalence of intracranial aneurysms is 2.3% (95% CI, 1.7-3.1%); most of these aneurysms are small and located in the anterior circulation. Risk factors are age, female gender, smoking, hypertension, excessive use of alcohol, having one or more affected relatives with SAH and autosomal dominant polycystic kidney disease. Most studies on risk of rupture have methodological weaknesses; an imp...
