[Extra-intracranial anastomosis: radio-clinical correlations].

25 patients have been operated on by means of extra-intracranial anastomosis (22 with STA-MCA anastomosis, 3 with occipital-MCA anastomosis). 23 patients underwent an angiographic study early after surgery (two weeks). The patency rate is 14 out of 23 (13 STA, 1 occipital anastomosis).

[Microsurgical treatment of a series of intracranial subtentorial arterial aneurysms].

A series of 60 arterial aneurysms is reported, pateints pre-operatively being from grade I to grade IV of the classification of Botterell. Microsurgical technique is emphasized : patients are operated on through the fronto-lateral approach described by Yasargil. The most patients with anterior communicating artery aneurysm are operated on from the right side, except for patients with only one left anterior cerebral artery.

[Intraspinal meningiomas. A series of 60 cases].

The authors present and compare two consecutive series of spinal meningioma, a total of 60 cases. From the aetiological point of view, the meningioma were more frequent than neurinoma. This study confirms its predominance in the female after the fifth decade.

[Cranial traumatism following a fall in children under 4 years of age (author's transl)].

This survey was carried out on 706 cases chosen at random, of cranial traumatism following a fall in children under 4; it underlines the fact that in most cases there is a favourable evolution. However, complications may always occur, even in apparently slight accidents. A clinical examination, although difficult to carry out, reveals important information for the detection and treatment of complications, which are mainly intracranial collections which are not always immediately detectable; this entails a constant observation for at least one week.
