[Efficacy of lumbar chemonucleolysis in the treatment of foraminal and extra-foraminal hernias].

A retrospective review of 1,200 nucleolyses performed over a three year period from January 1995 to December 1997 showed 116 discal treatments for foraminal and extra-foraminal localizations. The anatomic localization through the foramen and the intense clinical signs typify these anatomoclinical forms of lumbar hernia. In contrast with complex and disruptive surgical cure, percutaneous nucleolysis offers a precise and rapid method which can be performed in a very short time in outpatients with a success rate of 80%. Most localizations concern L3-L4 and L4-L5 hernias which give the best clinical outcomes.

Saccular intracranial aneurysms: endovascular treatment with mechanical detachable spiral coils.

PURPOSE: To evaluate endovascular treatment of saccular intracranial aneurysms with mechanical detachable spiral coils. MATERIALS AND METHODS: Fifty-three patients with 56 saccular aneurysms underwent endovascular treatment with spiral coils. All but five had symptomatic subarachnoid hemorrhage staged according to the Hunt and Hess classification as follows: stage IV or V (n = 20), stage III (n = 10), stage I or II (n = 20), and stage 0 (asymptomatic [n = 6]). RESULTS: Forty-seven aneurysms were occluded (100% occlusion) on follow-up angiograms with the following time distribution: 24 months for six aneurysms (six patients), 12 months for 14 aneurysms (11 patients), 6 months for 13 aneurysms (13 patients), 4 months for four aneurysms (four patients), and only immediate postprocedure study for 16 aneurysms (16 patients) (excludes two deaths and one failure). CONCLUSION: In this relatively small group, endovascular treatment with mechanical detachable spiral coils had a success rate of 90%, and it appears to be a rapid, reliable, and relatively safe technique in the treatment of life-threatening subarachnoid hemorrhage.

[Dural fistula of the cavernous sinus. Treatment through an intravenous approach apropos of 4 cases].

The authors report 4 cases of symptomatic dural fistula of the carotid cavernous sinus treated by transvenous coils. The objectives of dural fistula treatment are now clearly established and several methods are available. Abstention is the rule for asymptomatic forms, whereas symptomatic forms with ophthalmological complications may respond to manual compression of the jugular vein and the carotid artery, arterial embolization, radiotherapy or venous embolization. Arterial embolization results in complete cure in 72% to 78% of the cases, but it is limited by the meningeal supply of the internal carotid artery, with the microcatheter the transvenous route make it possible to treat the meningeal supply from the internal and external carotids without affecting the arterial system, but this technique is restricted by the anatomy of each patient.

[The role of magnetic resonance angiography in the follow-up of intracranial arteriovenous malformations treated by an intravascular approach].

The purpose of our work was to measure the accuracy and reliability of MR-Angiography in the study and follow-up of intracranial arteriovenous malformations, and in particular to evaluate the results of endovascular treatment. Over an 18-month period 4 patients with such malformations were examined by MR-Angiography. There was an angioma of the corpus callosum, a left parieto-rolandic angioma, a posterior thalamic angioma and a cerebellar angioma. All examinations were performed with a Magneton-Impact 1 Tesla machine (Siemens, Erlangen, Germany), using a head coil, MR-Angiography with time-of-flight sequences and differential arterial and venous saturations. Each patient was examined by MR-Angiography first at the beginning of treatment, then when ambulatory after embolization. The morphological study applied to the afferent vessels, the nidus and the efferent veins. MR-Angiography proved to be very good in identifying the arteries feeding the malformation, and this made it easier to evaluate the reduction of their input after treatment, without having recourse to any arteriography. Beside, analysis of the nidus was facilitated by the judicious arrangement of arterial and venous saturations. In fact, the systematic use of MR-Angiography in the follow-up of intracranial arteriovenous malformations makes it possible to measure, with full reliability, the efficacy of the endovascular treatment under conditions of comfort unequalled in these out-patients, and selective angiography sequences need to be performed only during therapeutic phases.

A comparative study of the anatomical, radiological and therapeutic features of the lumbar facet joints.

An anatomical study of the lumbar apophyseal joints was carried out to facilitate recognition of facet joint lesions, which we now examine routinely by percutaneous arthrography. Special attention was given to the configuration of the different compartments of the joint space and to its relationships with the contents of the intervertebral foramen. The abnormalities seen on lumbar facet joint arthrography are very varied; two major groups should be stressed: synovial fringe hypertrophy and pseudodiverticular synovial ectasia. The percutaneous approach to lumbar facet joint arthrography allows it to be used a therapeutic measure, with injection of anti-inflammatory drugs into the joint space, the beneficial effects of which were confirmed in our series. The precision, efficiency and cost-effectiveness of this outpatient technique justify and should encourage its more widespread application in the diagnosis and treatment of low back pain.

Contribution of discography to the diagnosis and treatment of lumbar disc herniation.

In this study, based on 600 cases of lumbar disc herniation treated by chemonucleolysis, the authors underline the importance of performing good discography and interpreting its results. A discographic classification of intervertebral disc deterioration is suggested. A CT-discographic study is reported and its results are compared with those of standard discography. On the basis of these studies, the authors have established methodological data concerning the efficacy of chemonucleolysis and its evaluation.

[Chemonucleolysis of lumbar intervertebral disk herniation].

Chemonucleolysis is an advantageous alternative to surgical treatment of lumbar disc herniation. To achieve the best results the indications must be strictly observed and the procedure itself must be technically perfect. In these circumstances a rapid, noninvasive and less expensive treatment of lumbar disc herniation is possible.

[Superselective angiography of the circumflex arteries in preoperative evaluation of femoral neck fractures].

The study of arterial vascularity in the head and neck of the femur is performed as an emergency exploration of femoral neck fractures by means of selective catheterization. The systematization of vascular lesions thus obtained is compared with the anatomical types of fractures. The posteromedial circumflex artery is not injured definitively as a rule, so that conservative osteosynthesis can be preferred to arthroplasty.

Percutaneous endoluminal angioplasty of post endarterectomy carotid stenoses.

Percutaneous transluminal angioplasty of the carotid artery was performed in four patients with recurrent stenosis following endarterectomy. Balloon catheter dilatation was successful in 3 of the 4 lesions. Post dilatation angiography demonstrated an increase in luminal diameter: there were no neurological complications with the procedure. PTA appears to be an effective method of treating recurrent stenosis following carotid endarterectomy.

Transcutaneous angioplasty of vertebral artery atheromatous ostial stricture.

The authors report experience of intravascular angioplasty of atheromatous ostial strictures of the vertebral artery in 24 patients. After reviewing the technique, they outline the indications provided through Doppler velocimetric data. The results seem to be encouraging as symptoms disappeared completely in 21 patients.

A comparative anatomical CT study of the vascular and nervous structures of the cerebello-pontine angle.

The arteries and veins of the cerebellopontine angle have been injected with a contrast medium permitting a precise anatomical reconnaissance of their topography and relations. These specimens have been explored by CT in order to define the opacified vessels and to differentiate them from the adjacent nervous tissue. Thus in CT it is possible to locate the cerebellar arteries, the petrous and medullo-pontine veins and the nerves of the cerebello-pontine angle. This study describes the normal appearance of the flocculus from the arteries and veins. Moreover it should contribute to the definition of the criteria of reliability of a CT diagnosis and its limits in the cerebello-pontine angle.
