Journal ArticleDOI
Natural history of unruptured intracranial aneurysms: probability of and risk factors for aneurysm rupture
TL;DR: It is concluded that such unruptured aneurysms should be surgically treated regardless of their size and of a patient's smoking status, especially in young and middle-aged adults, if this is technically possible and if the patient's concurrent diseases are not contraindications.
Journal ArticleDOI
Natural history of unruptured intracranial aneurysms: a long-term follow-up study
TL;DR: It is concluded that an unruptured aneurysm should be operated on, irrespective of its size, if it is technically possible and the patient's age and concurrent diseases are not contraindications to surgery.
Journal ArticleDOI
Factors Affecting Formation and Growth of Intracranial Aneurysms A Long-Term Follow-Up Study
TL;DR: Cessation of smoking is important for patients with unruptured aneurysms and possibly also for those with a prior subarachnoid hemorrhage, and women and cigarette smokers are at increased risk for intracranial aneurYSm formation and growth.
Journal ArticleDOI
Natural History of Unruptured Intracranial Aneurysms A Long-term Follow-up Study
TL;DR: Cigarette smoking, patient age inversely, and the size and location of the unruptured intracranial aneurysm seem to be risk factors for aneurYSm rupture, which decreases with a very long-term follow-up.
Journal Article
Natural history of unruptured intracranial aneurysms: probability of and risk factors for aneurysm rupture : Unruptured aneurysms
TL;DR: In this paper, the authors conducted a study to investigate the long-term natural history of unruptured intracranial aneurysms and the predictive risk factors determining subsequent rupture in a patient population in which surgical selection of cases was not performed.
