Effect of Time from Puncture to Recanalization on Poststroke Disposition and Associated Costs Open
BACKGROUND This study investigates the relationship between procedure time during stroke thrombectomy and acute posthospital disposition, as well as the associated costs. Despite extensive literature focusing on long‐term outcomes, immedia…

Is first-pass effect a meaningful metric to evaluate thrombectomy technologies? Open
Background Good clinical outcomes following stroke thrombectomy have been associated with successful reperfusion following a single pass, often referred to as the first pass effect (FPE). Inherent in FPE is a potential association with rap…

Dual-Volume Cone Beam Computed Tomography Helps Elucidate Dural Arteriovenous Fistula Anatomy in the Presence of Tantalum-Opacified Liquid Embolic Open
The presence of tantalum-opacified liquid embolic in incompletely treated dural arteriovenous fistulae (dAVFs) limits visibility of critically important angioarchitectural features. Modern cone beam computed tomography (CBCT) imaging can r…

Rescue intracranial stenting for acute large vessel occlusion using an Orsiro Mission drug-eluting balloon-mounted stent Open
Intracranial atherosclerotic disease (ICAD) is one of the most common causes of acute ischemic stroke and accounts for 33–50% of strokes in Asian, Hispanic, and black populations.(1) In patients with ICAD undergoing thrombectomy for large …

Volumetric Artificial Intelligence Analysis of Prerupture and Postrupture Cerebral Aneurysms: Assessment of Morphologic Change Open
All aneurysms in our cohort increased substantially in volume after rupture when measured with a semiautomated artificial intelligence volumetric measurement tool. However, linear measurements showed both increases and decreases in size. T…

E-021 Effectiveness and safety of single plane angiography use for endovascular thrombectomy in acute ischemic strokes due to medium vessel occlusions Open
Background The safety and effectiveness of endovascular thrombectomy (EVT) using single plane (SP) angiography systems for treatment of acute ischemic strokes (AIS) due to emergent large vessel occlusions (ELVO) has been shown in multiple …

Clinical and Angiographic Imaging Features of Isolated Cortical Venous Thrombosis Open
Background Cerebral venous thrombosis usually presents as dural sinus thrombosis. More rarely, it occurs in an isolated form (isolated cortical vein thrombosis; ICoVT). ICoVT is poorly recognized and underdiagnosed, and noninvasive imaging…

The Use of a Pipeline Embolization Device for Treatment of a Ruptured Dissecting Middle Cerebral Artery M3/M4 Aneurysm: Challenges and Technical Considerations Open
Prompt, effective treatment is necessary following aneurysmal subarachnoid hemorrhage to prevent recurrent rupture, which is thought to double mortality. Atypical ruptured aneurysms, such as blister or dissecting pseudoaneurysms, or those …

Adjustment of Malpositioned Woven EndoBridge Device Using Gooseneck Snare: Complication Management Technique Open
The Woven EndoBridge (WEB) is an intrasaccular flow-disrupting device for the treatment of wide-necked saccular cerebral aneurysms. As with any neuroendovascular device, complications in the form of malpositioning and migration must be man…

E-114 Coiling of recurrent aneurysms from the contralateral circulation following flow diversion: Technical aspects Open
Introduction One concern for aneurysm remnants following flow diversion are the limited retreatment options since the aneurysm sac cannot be directly cannulated through the stent pores. This argument is often used by groups using laser cut…

The Dilator-Dotter Technique: A Modified Method of Rapid Internal Carotid Artery Revascularization in Acute Ischemic Stroke Open
The dilator-Dotter technique may be a safe and effective modification of the traditional Dotter technique in allowing rapid ICA recanalization in cases of acute ischemic stroke due to tandem occlusions.

The Hydrogel Endovascular Aneurysm Treatment Trial (HEAT): A Randomized Controlled Trial of the Second-Generation Hydrogel Coil Open
BACKGROUND Aneurysm recurrence after coiling has been associated with aneurysm growth, (re)hemorrhage, and a greater need for follow-up. The second-generation HydroCoil Embolic System (HES; MicroVention, Inc) consists of a platinum core wi…

Intraoperative angiography via the popliteal artery: a useful technique for patients in the prone position Open
OBJECTIVE Intraoperative angiography can be a valuable tool in the surgical management of vascular disorders in the CNS. This is typically accomplished via femoral artery puncture; however, this can be technically difficult in patients in …

Effects of distance and transport method on intervention and mortality in aneurysmal subarachnoid hemorrhage Open
OBJECTIVE Most patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) initially present to a hospital that lacks a neurosurgical unit. These patients require interhospital transfer (IHT) to tertiary facilities capable of multidi…
