[Mortality and morbidity after complete surgical removal of 162 intracranial arteriovenous malformations (author's transl)].

A series of 162 arteriovenous malformations (A.V.M.) surgically removed is reported. All patients had a post operative control angiogram showing that the lesion had been totally excised. Supra and infra tentorial A.V.M. are included in the series as well as conscious and comatous patients. The overall mortality has been 11.1% and the mortality in conscious patients has been 6.9%. Mortality is higher when the volume of A.V.M. is over 60 cm3 and when a rupture has occurred. The influence of the operation on epileptic seizures, motor, speech or visual fields deficits has been reviewed in 109 patients who answered to the survey. Morbidity has been higher in patients with a cerebral heamorrhage, therefore the authors advise to operate these patients before the rupture when, for instance, seizures represents the only clinical picture. C.A.T. scan in these epileptic patients is a remarkable investigation to track down A.V.M.

[Measurement of multiregional blood volumes: a cerebral vascular autoregulatory phenomenon (author's transl)].

The variations in regional cerebral blood volume (RCBV) during controlled severe hypotension induced by sodium nitroprusside were studied in a series of 29 patients with aneurysms (14), meningiomas (6) and arteriovenous malformations. Two characteristic variations were noted. The RCBV and mean blood pressure (MPB) vary inversely, this type of variation being known as "Active variation". When pathological lesions are present the RCBV and MBP are modified in the same direction in the regions affected and this is called "Passive variation". A quantitative study in 21 patients showed that in the healthy regions there was a change from the active to the passive mode of variation for a MBP situated between 44 and 52 mm of mercury.
