Abstract | Background: The optimal treatment of symptomatic perineural (Tarlov) cysts is controversial. Numerous surgical techniques have been proposed with conflicting results. A series of Tarlov cysts treated with a novel surgical approach is presented.
Methods: Patients with surgically treated symptomatic perineural cysts during 2013-2016 were included. The main indications for surgery were persistent radicular symptoms, pelvic pain, urinary and/ or bowel disturbances. At surgery, the cyst was opened and fenestrated. The cyst wall was then closed with packing, fibrin glue and a pedicled vascularized fasciocutaneous flap rotated into the area for obliteration of the dead space. Patients were followed-up with clinical visits and repeat magnetic resonance imaging (MRI) scans.
Results: Seven consecutive patients were included. The mean age was 50.3 years (range, 25-80 years) and the mean duration of symptoms was 49.3 months (range, 3-130 months). With one exception, all patients had urine and/or bowel problems (incontinence) preoperatively. A lumbar drain was inserted in five patients. The mean follow-up period was 15.4 months. Symptoms improved in 4/7 patients, in two cases no clinical difference was noted while one patient deteriorated. In two cases, a spinal cord stimulator was eventually implanted. In all seven cases, a significantly decreased cyst size was noted on MRI.
Conclusions: Cyst fenestration and the use of a vascularized fasciocutaneous flap successfully obliterated all cysts, with satisfactory clinical efficacy. Larger and comparative studies are warranted to clarify the long-term effects of this surgical technique in patients with symptomatic Tarlov cysts.
