Use of the syringoperitoneal shunt in the treatment of syringomyelia.

A syringoperitoneal shunt is a one-way drain that empties cerebrospinal fluid from the pathological syringomyelic cavity into the abdomen. This treatment technique is based on the principle that the signs and symptoms of syringomyelia are caused by insidious interference with the condition of nerve signals in the spinal cord tracts due to either tearing or compression of the tracts by the distended cavity. A series of eight patients suffering from this disorder were operated upon using a syringoperitoneal shunt. The initial results seem to indicate that this technique is especially useful when pain, atrophy, or both dominate the clinical picture. Clinical signs, diagnostic studies, and surgical considerations are discussed.

[Hydro-syringomyelic cavities. Contributions of x-ray computed tomography and nuclear magnetic resonance. Value of syringoperitoneal shunt].

Twenty one patients with a spinal cord cavity are reported: 14 presented syringomyelia, 3 had a syringomyelic syndrome of another etiology, 4 had clinical symptoms different from those usually observed with such cavities. All patients had a plain C.T. and 20 had a C.T. of cervical and thoracic spinal cord 6 hours after cervical myelography with metrizamide or iopamiron. Morphologic and dynamic features given by this examination are reported. They allowed a discussion about the pathogenesis of the cavity: some cases were consistent with Gardner's theory, but the majority were consistent with Aboulker's. Nine patients had an examination by magnetic resonance imaging which gave the morphologic features necessary for the treatment: spinal cord cavity, Chiari malformation, hydrocephalus. Eleven patients were treated by a syringoperitoneal shunt: in spite of the short follow-up, the results seem favourable, especially for sensitivity and trophic troubles. Surgery should be based upon aggravating course and hydrocephalus. The results of syringoperitoneal shunting allow new considerations about pathogenesis.

Sequential CT scanning in radiation myelopathy.

Myelography is usually normal in radiation myelopathy. Occasionally it may show an enlarged spinal cord with block or a spinal cord of reduced size. It is assumed that the enlargement of the spinal cord is transitory, occurs in early stages of radiation myelopathy and is due to oedema, whereas atrophy is seen in later stages of the disease. This assumption however has not been clearly established by sequential radiological examinations. The purpose of this case report is to demonstrate such changes by repeated X-ray investigations.

[Ischemic pituitary apoplexy and cerebrovascular accident].

Operative findings of degenerative changes in pituitary adenomas are not uncommon; however, clinical apoplexy is rare. We report the case of a 43-year-old man who presents a sudden right hemiplegia with aphasia and right ophthalmoplegia, in relation with an ischemic pituitary apoplexy and cerebral vasospasm. A few cases of arterial obstruction or vasospasm associated with pituitary apoplexy have been reported in the literature. Cerebral arterial spasm has also been observed after pituitary surgery. Inclusion of blood or necrotic material in the subarachnoid space seems not to be the only mechanism of vasospasm. The role of hypothalamic dysfunction is considered.

Adult form of basal cell naevus syndrome: a family study.

A 32-year-old patient had marked reduction of visual acuity due to falciform folds of the retina and retinal detachment, and severe neurological abnormality: bilateral pyramidal involvement, fasciculation in all limbs and gait ataxia. Skull radiographs showed internal frontal hyperostosis; CT scan showed calcification of the falx cerebri, and multiple arachnoid cysts were shown by myelography. A naevoid lesion had previously been removed from the left forearm. There was a history of ophthalmological symptoms in the mother and the daughter of the propositus. His son has "café au lait" spot on the abdomen and dentigerous cysts. The diagnosis of an adult form of basal cell naevus syndrome with an autosomal dominant mode of inheritance is discussed.

[Therapeutic embolization in ORL pathology. Indications and results].

The progress of therapeutical embolization in otolaryngology was made possible by the arrival of new techniques which allowed the embolization of the different ramifications of the arteria carotis externa. The embolization technique is based on two principles: 1. The embolus is to be injected in a super-selective way, after catheterization of the pathological blood vessels. 2. The mass of the embolus has to be big enough to be able to obstruct the pathological vessel. Therefore the femoral way is mostly used. The aim of embolization is to create a spontaneous thrombosis around the used particles. The thrombosis thus succeeds in completing the embolization. The principal counter-indications against embolization are due to facts of a technical and a geographical order. Incidents and accidents are often related either to the catheterization, or to the contrast-media, or also to the anastomoses which become functional after the embolization. The major complications are hemiplegiae, aphasiae and eyesight troubles, all problems brought about by ischaemia are: --the indications for isolated embolization, amongst which have to be pointed out the surgical counter-indications, severe epistaxis, vessel malformations, important cranio-facial angiomatosis, the telangiectasical family angiomatosis of Rendu-Osler, and the antalgic effect of embolization, in particular in cancer treatment; -- an excellent indication for embolization is the prevention of massive hemorrhages and the simplification of the surgical act, in particular in hypervascularized ORL tumours, either benign or malignant, for instance the naso-pharyngeal fibrome and the whole of the malignant tumours and of the metastases of the ORL sphere. To conclude, we may say, that, within skilled hands and when taking the usual precautions, accidents in embolization are exceptional, and that embolization remains a therapeutical process with great prospects.

Multiple cerebral hematoma and viral encephalitis.

A patient with the clinical diagnosis of brain abcess presented with a CT brain scan showing an intracerebral hematoma. Subsequently bilateral spontaneous hyperdense lesions appeared. Autopsy showed the typical findings of viral encephalitis probably due to herpes simplex. It is stressed that the differential diagnosis of intracerebral hematoma includes viral encephalitis in the proper clinical setting.
