[Contribution of superselective arteriography and embolization in maxillofacial surgery. Apropos of 2 cases].

After describing the technique of embolisation and its therapeutic indications,the authors present two cases of different indications:--embolisation as the sole treatment,--pre-operative embolisation of a haemorrhagec tumour. These two cases illustrate two applications of the technique of embolisation:--Medical therapeutic value: making possible the reduction or stabilisation of the size of a vascular tumour difficult to excise surgically, in addition to eliminating the complications (haemorrhage, local trophic disturbance, pain);--Surgical interest: elective lesional embolisation such as is carried out at present greatly facilitates the surgical procedure in operations which may be associated with severe bleeding. Problems of healing are avoided. The procedure is carried out at the same time as selective arteriography. When in the hands of a skilled team, scarcely any risk is involved.

[Attempted treatment of a voluminous tympano-jugular and retropharyngeal glomus tumor by embolization].

The authors report a case of glomus tumor effectively treated by embolisation. The very large size of this tumor, the age and very poor general condition of the patient due to swallowing difficulties represented a contraindication to classical methods of treatment. Elective devascularisation was carried out by embolisation of the tumour itself using non-resorbable inert material by way of selective catheterisation of the vessels supplying it, almost all of which arose from the external carotid. Rapid and durable disappearance of part of the left cranial nerve involvement, in particular swallowing difficulties, reflected the effectiveness of the method. 18 months after this attempt at palliative treatment, the patient's condition remains satisfactory, with no detectable evidence of any recurrence or progression of the tumour.

[Cervical localization of a primary meningeal melanoblastoma].

The authors present a case of primary meningeal melanoblastoma localized in the cervical region, in a 47 year old woman. The intra and extradural, extramedullary tumor presented clinically and radiologically as a neuroma with central calcification. This case thus widens the possible causes of an intraspinal tumoral syndrome with radiological calcification.

[Meningeal arterio-venous fistulas with cortical venous drainage].

Pure dural arteriovenous fistulas are still not properly understood, and pose problems wich are far from being resolved. Among these, dural fistulas with cortical venous drainage represent a very special entity since they alone are expressed clinically by a neurological brain syndrome. Diagnosis is difficult and mistakes can be made as it is only by means of hyperselective arteriography of the branches of the external carotid that an accurate diagnosis can be made. However, their diagnosis assumes considerable importance since surgical or radiological treatment of hese fistulas brings about complete disappearance of clinical symptoms.

[Nasopharyngeal fibroma. Significance of super-selective angiography and embolization].

The authors describe a case of naso-pharyngeal fibroma which they treated, in order to prevent per-operative haemorrhage, by means of embolisation of the arterial pedicles. The result was very satisfactory, the operation being practically bloodless. They stress the advantages of angiography for obtaining information about these tumours. And, thinking ahead on the subject of embolisation, they weigh up the risk of haemorrhage due to surgery (which remains considerable whatever methods have been used hitherto) against the possible risk of embolism which appears to be negligible if it is carried out by a radiologist who is expert in this method.

[Arteriovenous fistulae of the dura mater. Clinical and radiological study of 13 cases].

The authors studied 13 new cases of fistulae of the dura mater. With reference to these 13 cases, and to the literature, they propose a classification according to the type of drainage of the fistula: direct, into a dura mater lake, into a cortical vein. This clasification enables a better clinical and radiological approach to these anomalies.
