[Saccular aneurysm of the superior vena cava].

The authors report a case of a saccular aneurysm of the superior vena cava in a 38 year old female. The diagnosis could only be made at thoracotomy because of the additional difficulty posed by a complete thrombosis of the aneurysmal pocket, which produced a particularly deceptive CT image. This type of lesion is exceptionally rare as a cause of a mediastinal "tumour" since only 24 cases of congenital aneurysm of the superior vena cava have been reported, of which only 4 were of the saccular type.

Auditory brain stem responses and cortical auditory-evoked potentials in difficult-to-test children.

Brain-stem-evoked responses (BERs) and cortical auditory-evoked potentials (AEP) were recorded in 24 children showing severe behavioral disorders. BER testing always requires sedation if not general anesthesia. This allowed us to perform precise acoustic impedance measurements, and thus to find 3 glue ears. The electrophysiological tests revealed whether there was sensorineural deafness, which was cared for if necessary. Finally, when the BERs were normal, we evaluated the modifications in the cortical AEP, in relation to a clinical classification closely related to that of the DSM III of the American Academy of Psychiatry.

[Primary intra-cerebral hemorrhage in the new born, nursling and child (author's transl)].

The authors report 6 cases of intracerebral hemorrhages in 6 children, of what appears to be, of primary origin. 3 cases concern children between the ages of 4 and 14 years; the 3 others are situated shortly after birth or during the first months of life. A review of the literature emphasizes the sporadic nature of these cases and the persistance of diagnostic and etiological problems as to the cause of these hemorrhages. In the course of reviewing articles as well as our own personal series, it is evident that the cat scanner has demonstrated its qualifications as a diagnostic tool in the early detection of the lesions, permitting a better adapted treatment, thus improving their prognosis. The prognosis appears to be linked : --to an early diagnosis --to whether or not the hemorrhage is of massive nature or not --to the precise location of the hematoma --to the neurological state of the patient at the time of treatment --to the absence of an associated pathologie (severe prematurity, coagulation pathology). The long distance prognosis in the case of these apparently primary hemorrhages remains uncertain, due to the high rate of recidivism at a later unpredictable date (one month or several years later); to the occurence or not of a hydrocephalus especially in the case of young infants; and frequent sequels affecting superior functions. This long distance prognosis seems, however, to be little affected by the recent acquisitions in diagnostic testing.

[Radicular artery thrombosis after cervical anterior approach for cervico-brachial neuralgia (author's transl)].

An anterior cervical approach completed by a bone graft is performed on a man suffering from cervico brachial neuralgia which did not improve by medical treatment and rest. During four months, the post operative course is excellent, with complete disappearance of pain and regression of the pre-existing neurological deficit. At the end of this period, the appearance of a major deficit within the field of the concerned root led to a selective brachial angiogram which revealed the existence of a radicular artery thrombosis.

[Injection of the sacrolumbar roots: a complementary method of staging sciatica. 18 cases].

The injection of the sacrolumbar roots allows, in the first place, the root to be made opaque in order to determine its morphology and, in the second place and above all, causes the disappearance of the radicular pain after injection of a local anesthetic, which helps the degree of sciatica to be identified. This method, which should be limited to exceptional cases, seems to be useful in patients who have undergone lumbar surgery and for whom the interpretation of contrast x-ray exams poses a particularly delicate problem. It can also be advisable when these exams are not conclusive or when the results do not coincide with the clinical data. Since March, 1974, 18 patients have undergone this exam. In 14 cases the disappearance of the radicular syndrome, after injection of xylocain close to the root, has allowed the root in question to be identified. In 3 cases radicular injection has practically made it possible to rule out an organic lesion. This exam had no side effect and was always tolerated even by two patients allergic to iodine.
