Traditional treatment options, such as unilateral ventriculoperitoneal (VP) or lumboperitoneal (LP) shunt placement, have high complication and failure rates and often require multiple revisions. The use of bilateral proximal catheters has been hypothesized as a method to improve shunt survival. The use of stereotactic technology has improved the accuracy of catheter placement and may improve treatment of IIH, with fewer complications and greater shunt patency time.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>The authors performed a retrospective chart review for all patients with IIH who underwent stereotactic placement of biventriculoperitoneal (BVP) shunt catheters from 2008 to 2016 at their institution. Bilateral proximal catheters were Y-connected to a Strata valve with a single distal catheter. We evaluated clinical, surgical, and ophthalmological variables and outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Most patients in this series of 34 patients (mean age 34.4 \u00b1 8.2 years, mean body mass index 38.7 \u00b1 8.3 kg\/m<jats:sup>2<\/jats:sup>; 91.2% were women) undergoing 41 shunt procedures presented with headache (94.1%) and visual deficits (85.3%). The mean opening pressure was 39.6 \u00b1 9.0 cm H<jats:sub>2<\/jats:sub>O. In addition, 50.0% had undergone previous unilateral shunt placement, and 20.6% had undergone prior optic nerve sheath fenestration. After BVP shunt placement, there were no cases of proximal catheter obstruction and only a single case of valve obstruction at 41.9 months, with a mean follow-up of 24.8 \u00b1 20.0 months. Most patients showed improvement in their headache (82.4%), subjective vision (70.6%), and papilledema (61.5% preoperatively vs 20.0% postoperatively, p = 0.02) at follow-up. Additional primary complications included 4 patients with migration of their distal catheters out of the peritoneum (twice in 1 patient), and an infection of the distal catheter after catheter dislodgment. The proximal obstructive shunt complication rate in this series (2.9%) was lower than that with LP (53.5%) or unilateral VP (37.8%) shunts seen in the literature.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>This small series suggests that stereotactic placement of BVP shunt catheters appears to improve shunt survival rates and presenting symptoms in patients with IIH. Compared with unilateral VP or LP shunts, the use of BVP shunts may be a more effective and more functionally sustained method for the treatment of IIH.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2017.8.jns162927","type":"journal-article","created":{"date-parts":[[2018,2,2]],"date-time":"2018-02-02T15:00:09Z","timestamp":1517583609000},"page":"136-144","source":"Crossref","is-referenced-by-count":12,"title":["Treatment of idiopathic intracranial hypertension via stereotactic placement of biventriculoperitoneal shunts"],"prefix":"10.3171","volume":"130","author":[{"given":"Michael","family":"Karsy","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hussam","family":"Abou-Al-Shaar","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah; and"},{"name":"College of Medicine, Alfaisal University, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian A.","family":"Bowers","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard H.","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1039","DOI":"10.1227\/01.NEU.0000255456.12978.31","article-title":"Stereotactic ventriculoperitoneal shunting for refractory idiopathic intracranial hypertension","volume":"60","author":"Abu-Serieh B","year":"2007","unstructured":"Abu-Serieh B, Ghassempour K, Duprez T, Raftopoulos C: Stereotactic ventriculoperitoneal shunting for refractory idiopathic intracranial hypertension.
