[Surgical treatment of sacral Tarlov cysts: about 20 cases]
Abstract
Tarlov cyst or perineural cyst is a local dilation of the subarachnoid space formed within the nerve root and filled with cerebrospinal fluid. There is no consensus on the best treatment of syntomatic sacral perinervous cysts. Many methods have been used to treat these symptomatic lesions, with variable results. We report a case series including 20 patients undergoing surgery for sacral Tarlov cyst. Our results were satisfactory; 80% of patients improved without neurological worsening in the post-operative period. Our surgical technique (sacral laminectomy+cyst puncture+establishment of dural sheat) described for the first time in this study seems to have been effective in the 20 cases reported in our study.
Le kyste de Tarlov ou kyste périneural est une dilatation locale de l'espace sous-arachnoïdien se formant au contact d'une racine nerveuse et est rempli de liquide cérébro-spinal. Il n'y a pas de consensus sur le traitement optimal des kystes périnerveux sacrés symptomatiques. De nombreuses méthodes ont été appliquées pour traiter ces lésions symptomatiques, avec des résultats variables. Nous rapportons une série de 20 patients opérés pour un kyste de tarlov sacré. Nos résultats étaient satisfaisants avec 80% d'amélioration et sans aggravation neurologique en post-opératoire. Notre technique chirurgicale (laminectomie sacrée + ponction du kyste + mise en place d'un manchon dure-mèrien), décrite pour la première fois dans ce travail, semble efficace dans les 20 cas rapportés dans notre série.
Keywords: Tarlov cyst; cyst aspiration; dural sheat; nerve root diverticulum; perineural sacral cyst; surgical treatment.
