[Sequential scintiscans. An easy method for testing C.S.F. shunts].

Different procedures have been since 1965 by the authors to test with isotopes the patency of shunts for hydrocephalus. The authors now measure the time 99m Technetium takes to appear in the thyroid gland after injection in the flushing device. This method shows easily and very quickly, with no computing, the dynamics of C.S.F. shunts. No hospitalisation is necessary and it is often possible to determine the cause of the disturbance in the shunt.

Sacral intraspinal lipoma associated with congenital iliac anomaly.

2 cases of a peculiar unilateral protuberance near the iliac bone with intraspinal abnormalities are reported. 8 cases have been described in the literature with this characteristic congenital association; they indicate the frequency of an occult spinal dysraphism which must be proved by myelography. In each case, surgical treatment of bone abnormality or of intraspinal lesions, or of both, should be discussed.

[Contribution of arteriography to the investigation of peripheral nerve tumours (author's transl)].

Based on their personal experience of the use of arteriography in 11 patients, the authors describe the angiographic appearances of both benign and malignant peripheral nerve tumours. They emphasise the reasons for errors, and the criteria enabling the precise nature of the lesion to be determined pre-operatively in the majority of cases. Other contributions supplied by angiography are discussed.

[Surgical management of primary peripheral nerve tumours (author's transl)].

A rational approach to the surgical treatment of peripheral nerve tumours can be determined by a knowledge of current concepts concerning their pathology and by clinical and arteriographic preoperative findings, and guided by extemporaneous histological examination results. It can be modified by the presence of metastases or associated phakomatosis.

[Comparative study of complications observed in ventriculo-atrial and ventriculo-peritoneal derivations. Apropos of 106 cases].

In this study that concerns 106 cases, authors insist on the frequency of the infectious and mechanical complications. They make a review of the etiologies and of the various materials used by themselves and study successively the mechanical, infectious and mixed complications, sector by sector. They drive, at each level, conclusions concerning the results with their subsequent lessons. Having recalled, in short, the principles of supervision of any child bearer of a "valve", they conclude by developing their present idea of the "ideal derivation" by on the base of the material submitted to experimentation. They insist on the value of the ventricular-peritoneal derivations in the new-born.

[Value of angiography in the diagnosis of peripheral nerve tumors].

In current practice, arteriograpy is already acknowledged, at the present time, as a method of primary importance which cannot be dispensed withfor diagnosis, prognosis and treatment. By opposition, considering pathology of the peripheric nerves, arteriography is often overlooked before chirurgical exploration though it affords the same advantages as in the remaining fields of pathology. Technically our preference goes to selective angiography by direct puncture of humeral or femoral artery. Arteriography will permit:-Visualisation of the location of the tumor close to the major vessels;-Evidence of the exact site of the efferent and afferent pedicles;-Discovery of other localisation. Mostly arteriography helps preoperatively to histological diagnosis. It must be recalled that benign neurinomas often assume a misleading aspect on the tumorography with stagnation of the contrast medium which might suggest malignancy. These benign tumors have three peculiar features: 1. Arteries are observed to stretch out around the lesion but never to narrow. 2. There is no explosive vascularisation ; hypervascularisation appears progressively, is located on the periphery of the lesion, and occupies but a part of the whole area. 3. Veins are not invaded but pushed apart and duly appear in normal timing. This peculiar aspect is quite the opposite of what can be observed in malignant tumors, which are, by far, less frequent.

[Tactical approach to tumours of the sacro-coccygeal region. Report of five cases (author's transl)].

The name of sacro-coccygeal tumors is used generally for various tumors embryologically different in their origin. Rare, but not exceptional in number, these sacro-coccygeal tumors may have various locations and different sizes which make diagnosis more or less difficult. Benign in the first months of life, risks of malignancy will increase with age. Systematical intrarectal exploration will help not to overlook pelvic forms and will recognize pelvic extension in other types. Once found out, the extension of these sacro-coccygeal tumors should be estimated by complementary examination choosen according to the presumed type of tumor and it is to be regretted that myelography should be so often neglected. Treatment should always be surgical with one piece aphotesis if possible; good preparation and exact reanimation of the child are necessary because sometimes surgical treatment may be a very severe aggression for small babies. Constant surgical and biological overall should be maintained for many years in order to discover as early as possible any local relapse or metastasis.
