Background:

Carotid angioplasty and stenting is gaining popularity as an alternative to carotid endarterectomy for the treatment of carotid bifurcation stenosis. The major concern with the procedure is the risk of embolic stroke which may be initiated by balloon angioplasty of friable atherosclerotic plaque. Elimination of angioplasty may result in a lower incidence of embolic complications.

Method:

We describe a case in which a self-expanding stent alone, without balloon angioplasty, was used to successfully dilate an atherosclerotic stenosis of the carotid bifurcation.

Results:

A moderate increase in vessel diameter, from 75% to 50%, was immediately observed after stent placement alone. No embolic complications were observed and follow-up plain film and ultrasound examinations showed progressive stent enlargement with excellent anatomic and hemodynamic results.

Conclusions:

In this case of severe carotid stenosis, the use of a self-expanding stent alone, without balloon angioplasty, resulted in excellent anatomic and hemodynamic improvement.

Résumé:

Résumé:Introduction:

L’angioplastie carotidienne et la mise en place d’une prothèse endovasculaire est une alternative de plus en plus populaire à l’endartérectomie carotidienne dans le traitement de sténoses de la bifurcation carotidienne. La préoccupation majeure associée à ce mode de traitement est le risque d’accident vasculaire cérébral embolique qui peut être déclenché par l’angioplastie par ballonnet de plaques athéroscléreuses friables.

Méthode:

Nous décrivons un cas chez qui seulement une prothèse endovasculaire auto-expansible, sans angioplastie, a été utilisée avec succès pour dilater une sténose athéroscléreuse de la bifurcation carotidienne.

Résultats:

Une augmentation modérée du diamètre du vaisseau, de 75% à 50%, a été observée immédiatement après l’insertion de la prothèse endovasculaire. Aucune complication embolique n’a été observée et on a noté un déploiement progressif de la prothèse avec d’excellents résultats anatomiques et hémodynamiques sur les radiographies simples et à l’échographie au cours du suivi.

Conclusions:

Chez ce cas de sténose carotidienne sévère, un excellent résultat anatomique et hémodynamique a été obtenu par la mise en place d’une prothèse endovasculaire, sans angioplastie.
