Age of collagen in intracranial saccular aneurysms.
BACKGROUND AND PURPOSE The chronological development and natural history of cerebral aneurysms (CAs) remain incompletely understood. We used (14)C birth dating of a main constituent of CAs, that is, collagen type I, as an indicator for biosynthesis and turnover of collagen in CAs in relation to human cerebral arteries to investigate this further. METHODS Forty-six ruptured and unruptured CA s...
متن کامل[Small saccular aneurysms in moyamoya disease].
Histopathological studies on the cerebral aneurysm in cerebrovascular moyamoya disease have been limited to only a few cases and the pathological details still remain obscure. Six moyamoya disease autopsy cases that satisfied the criteria of this disease proposed by Nishimoto in 1976 are studied. In addition to the routine neuropathological examination of the brains, detailed observa tion of th...
متن کاملComplex Analysis of Rupture Risk of Intracranial Saccular Aneurysms upon Hemodynamic and Geometric Parameters
The paper includes a new concept of assessment of rupture risk of intracranial saccular aneurysms using geometric and hemodynamic parameters of aneurysm, artery and blood. Previous decision systems are mainly based on the size of aneurysm and frequency of subarrachnoid hemorrhages, therefore after performing simulation tests it has been proved that the complex assessment of clinical cases is po...
متن کاملSaccular aneurysms in basilar artery fenestration.
Of 59 cases of vertebrobasilar junction aneurysms diagnosed and treated from January 1977 to April 1986, 21 (35.5%) saccular aneurysms arose in a fenestration of the proximal basilar artery. Defects of the media at the junctures of the fenestrated segments, as well as the possible presence of turbulent flow at the vertebrobasilar junction, may explain the high incidence of vertebrobasilar aneur...
