The Monopoint System (MS; Route 92 Medical, San Mateo, CA) is a telescoping catheter system with a single point of control outside the body, consisting of an 8F Guide Catheter (Base Camp), a 0.088\u2010in. inner diameter catheter\u2010extender (HiPoint 88), and a ledge\u2010reducing delivery catheter (Tenzing 8). In this study, we describe the MS technique for VSS and our multicenter clinical experience.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec id=\"svi212995-sec-0020\" xml:lang=\"en\">\n            <jats:title>Methods<\/jats:title>\n            <jats:p xml:lang=\"en\">We retrospectively reviewed consecutive patients who underwent VSS with the MS from 2022 to 2023 for intracranial hypertension and\/or pulsatile tinnitus at 13 sites. Base Camp is placed in the internal jugular bulb. HiPoint 88 is advanced over the Tenzing 8 through the stenosis. The stent\u2010delivery system is placed across the stenosis (inside the HiPoint 88), then unsheathed by HiPoint pull\u2010back, followed by successful stent deployment. Operators were also surveyed on MS performance.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec id=\"svi212995-sec-0030\" xml:lang=\"en\">\n            <jats:title>Results<\/jats:title>\n            <jats:p xml:lang=\"en\">\n              Seventy\u2010one patients were included, 97% female, mean age 40 \u00b1 11 years, body mass index 35 \u00b1 11. The primary indication for venous stenting was intracranial hypertension (79%, 56\/71) and\/or debilitating pulsatile tinnitus (87%, 62\/71). Visual changes were present in 74%, with papilledema in 63%. Hipoint 88 advanced beyond the stenosis over Tenzing 8 in all cases, and all stents (diameters 6\u201310 mm and lengths 30\u201380 mm) successfully deployed. Median stenosis decreased from 80% (interquartile range 75\u201387) to 0% (interquartile range 0\u20130) post stenting (\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              &lt;0.001). There were no Monopoint\u2010related complications. compared with the operators\u2019 typical VSS catheter setup\/technique, MS was rated \u201cbetter\u201d in 93% and \u201cslightly better\u201d in 6%; operators cited ease of crossing the stenosis, improved trackability and support, as well as lack of stent\u2010catheter length incompatibilities. Headache, pulsatile tinnitus, and papilledema improved in 81%, 95%, and 91%, respectively.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec id=\"svi212995-sec-0040\" xml:lang=\"en\">\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p xml:lang=\"en\">The MS is a safe and effective catheter platform for VSS.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/svin.124.001627","type":"journal-article","created":{"date-parts":[[2025,1,23]],"date-time":"2025-01-23T11:35:52Z","timestamp":1737632152000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Venous Sinus Stenting Using a Ledge\u2010Reducing Catheter, 0.088\u2010in.
