Association Between Brain Venous Drainage, Cerebral Aneurysm Formation and Aneurysm Rupture.
AIM The brain venous drainage dominance is generally divided into three groups; right or left dominance and co-dominance. There is no study in the literature examining the link between brain venous drainage and aneurysm formation or rupture. Our aim was to evaluate the association between venous dominancy, aneurysm formation and rupture. MATERIAL AND METHODS Eighty-six patients, who underwent...
متن کاملReview of cerebral aneurysm formation, growth, and rupture.
C erebral aneurysms (CAs) occur in 3% to 5% of the general population and are characterized by localized structural deterioration of the arterial wall, with loss of the internal elastic lamina and disruption of the media. 1 The most dreaded complication of CAs is rupture, the likelihood of which is related to several modifiable and nonmodifiable risk factors. Despite advances in surgical techni...
متن کاملAssociation of hemodynamic characteristics and cerebral aneurysm rupture.
BACKGROUND AND PURPOSE Hemodynamic factors are thought to play an important role in the initiation, growth, and rupture of cerebral aneurysms. This report describes a study of the associations between qualitative intra-aneurysmal hemodynamics and the rupture of cerebral aneurysms. MATERIALS AND METHODS Two hundred ten consecutive aneurysms were analyzed by using patient-specific CFD simulatio...
متن کاملEstimate of the maximum time interval between formation of cerebral aneurysm and rupture.
The recent publication of the results of the international study on unruptured intracranial aneurysms highlighted a paradox: there do not seem to be enough unruptured aneurysms in the population to account for the observed incidence of subarachnoid haemorrhage. Some authors have suggested that the answer to this paradox is that most aneurysms that bleed do so shortly after formation. This would...
متن کاملCerebral saccular aneurysm rupture after head injury.
When seen after head trauma, subarachnoid hemorrhage (SAH) often leads to an angiogram to look for vascular injury. Usually the study is negative; sometimes a traumatic aneurysm or dissection is seen. Occasionally, a conventional saccular aneurysm is found. The clinical history, physical examination, and computed tomography (CT) scan in such a patient may suggest that an aneurysmal SAH was the ...
