The Use of an Aspirating/Resecting Device to Reduce Stoma Closure Following Endoscopic Third Ventriculostomy for Aqueductal Stenosis.
Endoscopic third ventriculostomy (ETV) is commonly used to treat obstructive hydrocephalus. Closure of the stoma can be associated with symptom recurrence and need for further surgical intervention.To describe the use of a side-cutting aspiration device for treatment of aqueductal stenosis in patients undergoing ETV.A retrospective review of 30 consecutive adults with aqueductal stenosis treated with ETV using an adjunct side-cutting aspiration device between 2011 and 2013 was performed. Patients included in the study ranged from 35 to 64 years of age. ETV success was determined by the absence of stoma closure (aqueductal and cisternal flow assessed by high-resolution, gradient-echo magnetic resonance imaging), post-ETV symptom recurrence, and need for subsequent surgical intervention.Patients treated by using a side-cutting aspirator had no observed stoma closure (0%) and a 10% (n = 3) rate of post-ETV symptom recurrence. Three patients (10%) demonstrated a need for surgical revision following initial ETV with the side-cutting aspirator.Adult patients with obstructive hydrocephalus secondary to aqueductal stenosis exhibited a low rate of stoma closure with the use of a side-cutting aspiration device, and a rate of complications comparable to the known literature. Likewise, patients treated with a side-cutting aspirator may have lower symptom recurrence post-ETV and require fewer revisions in comparison with the known literature. As such, a side-cutting aspirator may be considered as a useful adjunct to traditional ETV for the treatment of obstructive hydrocephalus secondary to aqueductal stenosis.
