The authors\u2019 early practice favored shorter stents that only spanned the focal narrowing to reduce the metal burden. However, stent-adjacent stenosis (SAS) emerged as a significant failure mode prompting the use of longer constructs. In this study, the authors sought to compare the incidence of SAS, clinical outcomes, and angiographic findings between shorter and full-length stent constructs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS<\/jats:title>\n                    <jats:p>The authors conducted a retrospective analysis of patients with IIH who underwent TS stenting at Tufts Medical Center in the period from 2013 to 2023. Patients with medically refractory IIH symptoms and a significant cerebral venous pressure gradient were included. Symptom presentation, neuroimaging, venous manometry, preoperative and follow-up angiography, and clinical examination findings were recorded and analyzed across two categories of stent length: shorter (40 or 60 mm) and full length (80 mm). SAS was defined as de novo narrowing of the TS contiguous with the stent edge.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Endovascular treatment was successful in all 60 patients included in the study (48 females, mean patient age of 39 years). Three patients were treated with 40-mm stents, 13 with 60-mm stents, and 44 with full-length 80-mm stents. SAS was documented in 8 patients (13%) and was significantly more frequent (p &lt; 0.01) among those with shorter stents (6\/16), with 3 patients requiring reintervention using a second overlapping stent. Among the 44 patients with full-length constructs, 2 demonstrated SAS at the residual unstented TS lateral to the torcular Herophili. After a mean follow-up of 40 months, 29 patients (48%) reported persistent symptoms, although there was no significant difference in this rate between the stent groups. Full-length constructs demonstrated a more favorable postoperative reduction in TS pressure gradients (p &lt; 0.01) and lower gradients on follow-up (p &lt; 0.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>SAS is a clinically relevant complication following VSS in patients with IIH and may contribute to persistent symptoms and the need for reintervention.
