S everal factors suggest a hereditary basis for some intracranial aneurysms. The occurrence of familial aggregates of intracranial aneurysms is rare but well documented. 1–4, 7, 8, 10, 11, 18, 19, 23, 27, 29 The inherited condition of polycystic kidneys is associated with an increased incidence of intracranial aneurysms. 6 The familial occurrence of intracranial aneurysms has been described in association with hereditary connective tissue disorders (Ehlers-Danlos syndrome and pseudo-xanthoma elasticum). 11 The following six cases of intracranial aneurysm

Angiotomography of intracranial aneurysms

Analysis by a new method of angioautotomography

Osamu Sato, Masatoshi Kobayashi, Hiroshi Kamitani, Takashi Kokunai and Jinichi Sato

intracranial aneurysms. Method and Clinical Material Technique We have already made a preliminary report regarding the method 11 but since we have made further revisions, it may be worthwhile to explain briefly the outline and the characteristics of the method. In conventional angioautotomography, 12 the rotational axis of the head lies at the midline occipital region and, consequently, only midline sagittal section tomography is available. However, if the rotation axis can be changed to any location, off-midline section as well as frontal section tomography is

Ruptured intracranial aneurysms

Case morbidity and mortality

Kalmon D. Post, Eugene S. Flamm, Albert Goodgold and Joseph Ransohoff

R ecent papers on microsurgical treatment of intracranial aneurysms have reported excellent surgical results. 9, 21 Few studies, however, have dealt with the total case morbidity and mortality in which patients not selected for surgery are included in the statistics. 6, 20 The evaluation of a total management regimen is important to determine how many patients do not survive their subarachnoid hemorrhage (SAH) or its complications before definitive treatment. In this way, some assessment can be made of the overall morbidity and mortality of ruptured

T rauma to intracranial arteries is not rare when one considers the incidence of intracranial hematomas that complicate head injuries. Excluding carotid-cavernous fistulas, however, traumatic saccular aneurysms and arteriovenous fistulas are distinctly uncommon. There are few more than 100 cases recorded in the world literature. 1–10, 12–18, 20–37, 39–47, 50–62, 64–69, 71–73 That intracranial aneurysms may occur after trauma to the intracranial arteries has been shown experimentally and confirmed at pathology. 34, 70 In 1891, Bollinger 11 suggested that

A ccessible intracranial aneurysms that have a narrow base are amenable to clipping, and at the present time there seems to be little doubt that this is the surgical therapy of choice. For inaccessible aneurysms other methods, mostly experimental, have been used and reported with enthusiasm. 6 Unfortunately, these techniques necessitate equipment and technical skills not available to most neurological surgeons. In the group of intracranial aneurysms that are accessible but impossible to clip because of a broad base or incorporation of cerebral nutritive

A lthough intracranial aneurysms associated with moyamoya disease are said to be relatively rare, a considerable number of such cases have recently been reported. Such reports range from the first case described by Pool, et al. , 11 in 1967, to the last four cases by Adams, et al. , 1 in 1979. We report the case of a patient with multiple aneurysms associated with unilateral moyamoya vessels. We also discuss the 22 other cases found in the literature.

R esearch on the development of intracranial aneurysms has been performed in numerous fields such as hemodynamics, 18 biomechanics, 4 histology, 6 and computational fluid dynamics. 21 Although these studies have provided new information regarding factors involved in aneurysm development, the results cannot be directly related to the growth rates of aneurysms. Given that an aneurysm's size is a main determinant in its risk of rupture, 26 lesion growth rates are a key factor in the relation among aneurysm prevalence, the risk of aneurysm rupture, and

I nvestigation into the causes of the genesis, growth, and rupture of intracranial aneurysms is relevant. The most frequently occurring aneurysms are saccular and considered to be the combined result of a multifactorial pathogenetic complex. 36 Both congenital and acquired factors have been investigated. 5, 17, 34, 35, 40 Hemodynamic stress at arterial bifurcations, congenital medial defects, and degenerative arterial wall changes are believed to contribute to aneurysm development. 9 Other factors, such as hypertension, smoking, atherosclerosis, and alcohol

Polycystic kidney disease and intracranial aneurysms

Early angiographic diagnosis and early operation for the unruptured aneurysm

Toshimitsu Wakabayashi, Shigekiyo Fujita, Yoshiro Ohbora, Tohru Suyama, Norihiko Tamaki and Satoshi Matsumoto

T here have been many reports on the coexistence of polycystic kidney disease (PKD) and intracranial aneurysms since 1904 when Dunger 8 discussed the frequent association of these two conditions. The incidence of intracranial aneurysms in PKD series has been reported to be 17%, based on autopsy studies. 5 Once rupture of the aneurysm has occurred in patients with PKD with severe renal dysfunction, the prognosis is poor. Therefore, it is reasonable to establish the diagnosis early, and to perform prophylactic surgery for these unruptured intracranial
