[Responsibility of the left renal vein and inferior vena cava in certain cases of myelitis and syringomyelia. Value of ligation of the venous reno-spinal trunk. Apropos of 30 cases].

Certain diffuse forms of myelitis may be due to raised intra-spinal venous pressure resulting in veritable "varicose veins of the spinal cord". The origin of this increased pressure is often multifactorial, but may be due to venous reflux of blood from the left kidney into the intraspinal plexuses via the reno-spinal trunk. Ligation of this trunk results in a considerable and often complete improvement in the neurological syndrome. This operation was performed for the first time by our team in 1973 and since then has been successfully performed on 30 occasions for 21 cases of myelopathy and 9 cases of syringomyelia.

[Should the aneurysms of Osler's disease be investigated and operated on prior to hemorrhage?].

Neurologic accidents are today the first cause of mortality following bacterial endocarditis through ischemia or mycotic aneurysm rupture. Authors propose a protocol management by complete cerebral angiography and CT scan as soon as the least neurologic sign appears. A headache is the most frequent of these signs. 35 patients were explored during 3 years and 10 treated surgically. These authors conclude that: mycotic aneurysm must be detected aneurysm with subarachnoid haemorrhage must be operated on as soon as possible. With unruptured aneurysm, surgical decision is more difficult: sequential angiography after excision of the most dangerous aneurysm, demonstrates that an aneurysm can appear, enlarge, diminish or spontaneously resolve. Carrying on with this protocol should allow an answer to this question.

[Anatomical study of different modes of anastomosis between the facial artery and ophthalmological artery at the medial angle of the orbit (author's transl)].

In 21 autopsy specimens, we performed latex injection, and studied the rate and the diameter of the anastomosis between the ophthalmic artery and the facial artery: we find 26 cases in 42 face-sides, 60 %; which can supply rapidly a circulatory insufficiency. The anastomosis which go to the ophthalmic artery from the others branches of the external carotid are less frequent.

[Computer tomography changes in multiple sclerosis (author's transl)].

An attempt is made to evaluate the semiological data supplied by computer tomography, following its use on several occasions in 4 patients with multiple sclerosis. Three known signs in the encephalic forms are defined: cerebral atrophy, low density plates of sclerosis that do not take up the contrast medium, and those that do. These localized lesions are distinguished by their frequent multiplicity, often periventricular location, and absence of a mass effect. The semiological value of these signs involves discussion on the poor results of statistical evaluation, the significance of histology examination results, which are still being studied, and more particularly the variability, the best evidence of which seems to be the beginning and/or the changes occurring in contrast medium uptake. To this major diagnostic argument can be added the discovery of multilocular lesions which are sometimes present without clinical manifestations. Computer tomography is an essential procedure for establishing the differential diagnosis of multiple sclerosis, avoiding numerous valueless arteriographies, is a fundamental method for early positive diagnosis, and perhaps an element for establishing prognosis.

[Cerebral ischemia, treatment by vascular micro surgical technique: intra-extra cranial anastomosis (author's transl)].

The introduction of vascular micro-surgical techniques has allowed to treat cerebral ischemia, through extra-intra-cranial anastomosis, when the causative arterial lesions have a surgically unfavorable location. Thirty patients underwent brain revascularization through extra-intra-cranial micro-anastomosis between the superficial temporal artery (branch of the external carotid artery) and a cortical branch of the middle cerebral artery. Twenty five patients had definite sensitive and motor deficits. Five patients, on the other hand, underwent preventive surgery because of transient cerebral ischemia. In our series, the global rate of the microanastomosis patency is 78%. When the anastomosis is patent, 85% of the cases with motor deficits are cured or improved. The results are even more favorable in case of transient cerebral ischemia, for the anastomosis in such cases was always patent. None of these later patients had ischemia attacks with a one-year follow-up.

Jugular venous reflux in cerebral radionuclide angiography: an explanation.

A case of isotopic jugular venous reflux, reaching the opposite jugular vein, is described. Phlebography and aortography were simultaneously performed in this patient and showed the innominate vein narrowed and pinched between the sternal notch and the aortic arch. This narrowing depends on the position of the left arm.

[Extra-intracranial arterial bypasses. Evaluation of their permeability by use of the Doppler effect].

40 temporo-sylvian anastomoses were controlled using Doppler ultrasonic examination. The results are compared to post-operative arteriograms. The Doppler examination has proved to be highly accurate when compared to contrast arteriography in the survey of extra-intracranial anastomosis. This non invasive procedure can easily be repeated. However the size of the revascularized area cannot be estimated. The simultaneous isotopic studies of regional cerebral blood flow could provide a means of quantifying the results of the anastomoses.
