[Is it necessary to operate on asymptomatic aneurysms? Apropos of 114 surgically treated asymptomatic aneurysms].

A six years retrospective analysis of asymptomatic aneurysms (A.A.) was done in 4 neurosurgical departments: 114 AA were clipped in 99 patients. In 44 patients (48 asymptomatic aneurysms) the surgical procedure was achieved in one step for both symptomatic and asymptomatic aneurysms. In 59 patients (66 asymptomatic aneurysms) the surgical procedure was delayed as it necessitated a second and elective craniotomy. As regard the treatment of asymptomatic aneurysms, there was no morbidity, and one death due to a massive pulmonary embolism. These surgical results are undoubtebly better than the risk of hemorrhage from unruptured aneurysm as emphasized in the literature.

[Intracranial hematoma in ruptured aneurysms. Apropos of 57 cases].

In 200 consecutive cases of ruptured aneurysms volume of resulting hematomas exceeded 5 ml in 57 patients (28.5%) and 50 ml in 25 patients (12.5%). We have studied the radio anatomical and clinical datas of these 57 cases: In most of them (90%) the aneurysm situation appears to determine hematomas characteristic features. Fatal issues are related to hematoma volume when above 50 ml and to vasospasm in other cases. Results in the 48 operated cases lead to advise neurosurgeons against surgical procedure when volume is greater than 60 ml in grade V patients (unless operation could take place immediately after rupture onset), and when severe intra ventricular hemorrhage is present. Death in ruptured aneurysms is a consequence of hematomas volume in at least 10% cases. Hematomas or vasospasm are responsible for sequellae or fatal issues which still occurs in 15-20% of overall population of patients with ruptured aneurysms, despite improvement in management and timing. Cases finding and preventive surgery of non incidental aneurysms should be a matter of concern.

[Compression of the cauda equina by osteoarthritic pseudo-spondylolisthesis, with overlying signs of deficit. The possible role of a venous mechanism].

The authors report the case of a patient suffering from paraparesis where a venous pathology seemed to be responsible, and the literature is reviewed. A cauda-equina compression by L4/L5 arthrosic pseudo-spondylolisthesis caused troubles of the spinal cord venous drainage, seen at the myelography. There was a neurological deficit above the L4/L5 compression with a psoas and quadriceps deficit. After a L4/L5 laminectomy the neurological signs improved rapidly.

Common origin of the arterial blood flow for an arteriovenous medullar fistula and the anterior spinal artery: a case report.

A common origin of the blood supply to a dural arteriovenous malformation and to the spinal cord from the same segmental artery is very rare. This obviously contraindicates embolization of the fistula. Demonstrating the location of the normal spinal blood supply system is therefore mandatory to avoid postoperative complications. The visualization of the normal blood vessels can be masked by a steal phenomenon, but it must at all costs be obtained. The authors describe one such case.

[Intraspinal epidural hematoma in the hemophiliac].

The authors report a series of 11 epidural haematoma in hemophilia. Of these, one case is observed in the department of Neurosurgery at the CHRU. From this study, main points results: a mechanic etiology was found in four cases; the main clinical and radiological signs are those of epidural haematoma; the indication to operate is required and the hemophiliacs should receive a "substitutive" treatment as soon as possible.

[Medical treatment of prolactin-secreting pituitary adenomas. Influence of the size of the adenoma].

Forty-two patients with prolactin-secreting pituitary adenoma (prolactinoma) demonstrated by a radiologically abnormal sella turcica and hyperprolactinaemia were treated with bromocriptine. Baseline serum prolactin levels, which before treatment correlated with the size of the adenoma, returned to normal under bromocriptine in 30 out of 36 cases; in 6 female patients, however, they were lowered but remained moderately high. The dose of bromocriptine and the time required for normalization of prolactinaemia correlated with the size of the tumour. In 11 patients with macroadenoma bromocriptine dosage and prolactinaemia were inversely correlated; in 8 of these the adenoma was reduced in size. In 12 cases where the long-term treatment was interrupted, prolactinaemia rose again, suggesting that the medical treatment alone has no lasting curative effect.

[Lumbar phelbography without catheterization. Technic, indications and results in the diagnosis of intervertebral disk herniation].

The authors present a new method of lumbar phlebology without catheterism by direct venous puncture of the femoral veins. An analysis of 300 contrast tests maked it possible to identify different types of pathological images characterized by disappearance and displacement of epidural veins corresponding as a rule to discal hernia when the uncharacteristic shadowy images do not allow one to make a precise conclusion or to determine whether an operation is needed. With equal reliability (96 percent), lumbar phlebography without catheterism is, by its simplicity and harmlessness and the absence of minor and major venous complications, preferable to phlebography by catheterism. Carried out in all subjects, whatever their age, without special precautions, it seems to us to now be the most desirable test to be used in the radiological investigation of lumbar discal hernias.

[Nondiscal sciatica without organic lesion].

Among 1 800 patients operated on for hernia of the disc, 2% were completely negative on surgical exploration. Since a psychiatric aetiology might be involved, these patients were again given physical examination, clinical psychiatric examination and a personality test (minimult). This psychometric examination yelded pathological results in 68% of these patients. A comparison with two control groups operated on for hernia of the disc permitted a distinction of statistically significant differences. The results are compared with similar studies by other authors on patients with lumbalgia and dorsalgia. A practical approach is defined.
