Abstract

Purpose: Slit ventricle syndrome (SVS) remains a major problem for early shunted children. Several conservative and surgical treatment paradigms have been suggested; however, there is no consensus on the optimal surgical treatment. We present our experience using bilateral subtemporal decompressions with dura and arachnoid opening for the treatment of a subgroup of children with severe and resistant SVS. Methods: Fifteen children with severe and resistant SVS underwent a modified bilateral subtemporal craniectomy, with dura and arachnoid opening. Their clinical and radiological data were retrospectively reviewed. Results: Seven (46.6%) patients had a complete recovery from their symptoms with a follow-up of 5.9 ± 2.6 years.The remaining eight (53.3%), underwent additional surgeries. Four (26.6%), had a single proximal shunt revision after dilatation of their ventricles. Following these procedures these four children are well and stable with a follow-up of 1.8 ± 2 years. The other four had further cranial vault expansion, one of which was followed by a proximal shunt revision. Thus, 11 of these 15 patients (73.4%) had a very good outcome, attributable to this technique, with a mean follow-up of 4.5 ± 3 years. Conclusions: Modified bilateral subtemporal decompression with dura and arachnoid opening yields a high cure rate for severe and resistant slit ventricle syndrome. Proximal shunt revision may be safely performed in a subset of patients that dilate their ventricles following the procedure. Further cranial expansion may be reserved for children with recurrent SVS symptoms who do not respond to STD and remain with very small ventricles.
