Although it might probably appear a rash, even ill-conceived, project to dedicate a mono graph to cerebral angiography at a time whilst CT appears crucial neuroradiologic technique, this can be certainly now not the case. in addition, the authors are conscious of the need of taking those new options into consideration. Cerebro-arterial occlusive illnesses are usually the reason for acute and chro nic neurologic disturbances. The authors' target in getting ready this e-book was once to illustrate the price of neuroradiology within the analysis of those stipulations. they've got comprehensive their objective, and in particular, they've got succeeded in demonstrating how angiography and CT supplement one another. They indicate absolutely the necessity of top of the range in angiographic imaging; certainly, arterial occlusive illnesses could have a really capricious and unforeseen evolution that may be followed-up by means of iterative CT examinations - for example as soon as per week - yet angiography, that's played just once, has to be as excellent and informative as attainable. either authors acquired a part of their education within the Neuroradiologic leave ment of the college health facility in Strasbourg. i'm therefore more than happy to discover during this publication either the perfection i used to be conversant in seeing in G. B. BRADAc's iconography and the sound judgement I continually preferred in R. OBERSON. hence, it's with nice delight that I write this foreword. it truly is my want that either authors in attaining the popularity they rightfully deserve within the Univer sities of Berlin and of Lausanne.

In another 25% a slightly generalized atherosclerosis was seen. In some patients of the last group an ulceration of the carotid bifurcation was suspected. a. from the carotid siphon and the site where this vessel divides into its peripheral branches. In spite of occlusion near the carotid siphon the lenticulostriate arteries are almost always recognizable, since some of these vessels (the medial lenticulostriate arteries) arise from the anterior cerebral artery. Furthermore, these vessels are frequently dilated.
A. , 1975 b; ErNSIEDEL, LECHTAPE and LECHTAPE-GRUTER, 1977). Lesions in this region were visible in 4% of our cases. Etiology. The cause of the lesions in the majority of adults and older patients appears to be atherosclerosis. In young patients an embolic occlusion or an arteritis can occasionally be diagnosed but very often a definitive cause cannot be found. Angiographic Findings. On the carotid angiogram an increased vascularization is visible in the occipital region due to collateral flow from peripheral branches of the anterior and middle cerebral arteries to the posterior cerebral artery.
107). In occlusion of the internal carotid artery a collateral circulation may arise from the external carotid artery. The most frequent path taken is from the internal maxillary artery -tophthalmic artery, which is retrogradely filled, -tcarotid siphon. More seldom is a collateral flow from the superficial temporal or middle meningeal arteries to the ophthalmic artery and carotid siphon or from the external maxillary artery to the angular artery and further to the ophthalmic artery and carotid siphon.
