Intradural venous sinuses are commonly visualized structures in the CT brain, even in noncontrast images. Rarely, hypoattenuating focal lesions may be observed within their lumen as a coincidental finding, which may remain undiagnosed. However, when such lesions appear in the patients who are scanned for head injury, they might pose diagnostic difficulties.

Article Synopsis
- Advancements in high-resolution imaging and computational techniques have made clinical simulations for endovascular procedures increasingly practical, improving treatment planning for devices like virtual and braided stents.
- The use of 3D printing for realistic simulations aids in understanding complex procedures, facilitating training for both new and experienced surgeons dealing with conditions like arteriovenous malformations.
- Successful integration of medical and engineering approaches is critical for the future, along with necessary regulatory approvals and commercialization of these simulation technologies.

Recently, an interesting study regarding "Dural sinus septum: an underlying cause of cerebral venous sinus stenting failure and complications." was published, to our knowledge, being the launching point of the clinical/interventional applications of this intraluminal variation. Herein, we wish to highlight paramount anatomical, clinical, and stent placement considerations related to DSS located in the dural venous sinus at the posterior cranial fossa and the interventional complications caused by the presence of this variation during stenting procedures.

Dural sinus stenting is an increasingly recognized intervention for the treatment of lateral sinus stenosis. This procedure can be challenging in tortuous anatomy and in the presence of intraluminal septa because of poor trackability and crossability of long sheath commonly used for stenting. We report a technique using a pilot angioplasty balloon positioned at the distal end of the long sheath that improves its navigability in dural sinuses and facilitated the intervention.

Division of Interventional Neuroradiology, Johns Hopkins Hospital, Baltimore, Maryland, USA
Background: Transverse sinus (TS) stenting is a valid treatment alternative for patients with intracranial hypertension caused by underlying bilateral TS stenoses. Its mid-term patency has, however, not been well documented.
Objective: To assess the 6-month patency of TS stenting using subtracted CT venography (CTV).
