Background Blood urea/creatinine (U/Cr) ratio is considered to be an ideal biomarker of dehydration. We investigated the association between the U/Cr ratio trajectory and delayed cerebral ischemia ...

(6) Where ‘D’ is the inner lumen diameter of the catheter, ‘µ’ is the dynamic viscosity of blood, and ‘L’ is the length of the catheter.Some assumptions are required to apply this relationship, ...

Background Antiplatelet and antithrombotic medication management before, during, and after neurointerventional procedures has significant practice variation. This document updates and builds upon the ...

Neurovascular catheter technology has rapidly evolved over the past decade. While performance characteristics are well known to the practitioner, the design features of these new-generation catheters ...

Background A study was undertaken to determine the typical length, diameter and taper of vessels in the anterior cerebral circulation. Methods The sample size was calculated at 100 patients based on ...

Background In contrast to conventional CT perfusion (CTP) imaging, flat panel detector CT perfusion (FD-CTP) imaging can be acquired directly in the angiosuite. Objective To evaluate time-resolved ...

Background Patients with intracranial atherosclerotic stenosis (ICAS) are prone to stroke recurrence despite aggressive medical treatment. Further assessment of the anatomy and physiology of ICAS is ...

Objectives This is the first FDA approved IDE study for mechanical thrombectomy to treat distal occlusions. DISTALS is a randomized study planned to evaluate the safety and effectiveness of the ...

Background Despite successful recanalization via mechanical thrombectomy (MT), only half of acute ischemic stroke (AIS) patients achieve functional independence. Post-MT hemodynamic features are ...

Background Transvenous embolization (TVE), such as selective shunt occlusion, is the first line treatment for cavernous sinus dural arteriovenous fistula (CSDAVF). Despite the favorable outcomes of ...

Background Transcranial Doppler (TCD) is a non-invasive, bedside tool that allows for real-time monitoring of the patient’s hemodynamic status following mechanical thrombectomy (MT). This systematic ...

Introduction The LVIS Blue is an FDA-approved stent with 28% metallic coverage that is indicated for use in conjunction with coil embolization for the treatment of intracranial aneurysms. Given a ...
