We report on our experience with this endoscopic technique. Materials and methods: Eighteen patients with primary or secondary aqueductal stenosis underwent endoscopic aqueductoplasty (EA) with or without stenting between July 2004 and January 2007. EA, EA with a stent, EA with endoscopic third ventriculostomy (ETV), and EA with stenting in addition to ETV were performed in eight, five, three, and two patients, respectively. A repeat endoscopic procedure was done in one patient. EA with a stent was performed in case 1, 8months after first endoscopic procedure. In four cases, aqueductoplasty with stent was performed through a suboccipital approach. Results: There were no deaths due to the neuroendoscopic procedures. All of the patients showed improvement or resolution of their preoperative symptoms, although in case 1 a new endoscopic procedure was performed: EA with a stent. Conclusion: Cerebral aqueductoplasty is an effective and successful treatment for membranous and/or short-segment stenosis of the sylvian aqueduct. Endoscopic aqueductoplasty candidates must be selected very carefully but longer follow-up periods are necessary to evaluate long-term aqueductal patency after aqueductoplasty.
