What the trial is, and whether it could suit you
Subjects are enrolled in the study following signature of the Informed Consent Form and confirmation of eligibility criteria.
During the screening/baseline phase, demographic and clinical data, medical history, concomitant medications, available imaging (contrast-enhanced CTV or MRV), and THI and HIT-6 questionnaires are collected. Pre-procedural medication are initiated one week prior to the procedure, in accordance with standard medical practice.
Subjects are admitted prior to the procedure according to local practice. Required laboratory tests, neurological assessments (modified Rankin Scale and NIHSS), and confirmation of informed consent are completed prior to any study-specific procedures.
The index procedure includes cerebral venography with confirmation of a significant transverse-sigmoid sinus stenosis and a pressure gradient greater than 5 mmHg. Following confirmation of pro
