Barrow Ruptured Aneurysm Trial
Ruptured Cerebral AneurysmSubarachnoid Hemorrhage (SAH)With evolving endovascular technologies there is a growing debate centered on the relative safety and efficacy of the currently accepted alternatives for the treatment of ruptured cerebral aneurysms in the face of acute subarachnoid hemorrhage (SAH). The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular coiling of acutely ruptured cerebral aneurysms in a prospective, randomized fashion.

Coil Assisted Flow Diversion Safety and Performance Study
Intracranial AneurysmCerus Endovascular is sponsoring a prospective, single arm, multi-center study to document the safety and performance of Neqstent in adjunctive therapy. The purpose of the study is to document safety and performance of the Neqstent in adjunctive therapy in treatment for patients with intracranial aneurysms (IA).
Acupoint Stimulation and Cranial Endovascular Treatment
Cerebral AneurysmIn this prospective randomized controlled trial, the subjects will be assigned to group transcutaneous electrical acupoint stimulation (TEAS) and group control (no intervention). The postoperative outcomes including NIHSS (National Institute of Health stroke scale) score, morbidity and mortality will be evaluated during hospital stay and by one year after surgery.
Framing Eighteen Coils in Cerebral Aneurysms Trial
Cerebral AneurysmThis trial is being conducted in order to compare angiographic outcomes in patients receiving 0.014-0.0155" platinum framing and filling coils (larger diameter coils) versus those treated solely with coils less than 0.014" (with a standard diameter). Hypothesis: Angiographic occlusion at follow-up imaging will be more frequent in patients receiving 0.014-0.0155" platinum coils during embolization compared to those receiving smaller-diameter coils.
Impact of Neurochecks on Sleep in Critically Ill Adults
Cerebral AneurysmBackground: Following acute brain injury (ABI), patients are monitored in the intensive care unit (ICU) where providers rely on frequent neurological examinations ("neurochecks") to assess for neurodeterioration. Serial neurochecks are part of guideline recommendations, but there is equipoise between hourly (Q1) and every-other-hour (Q2) evaluation. In the ICU, care-related awakenings occur frequently, but it is unclear if differential neurocheck frequencies result in differential sleep, providing the scientific premise for this proposal. Population: Twenty-two patients (N=11 per group) who have undergone elective aneurysm coiling will be enrolled. On post-operative day (POD) 0, patients will be screened and approached for informed consent if they do not meet exclusion criteria, e.g., prior intracranial injury, sleep disorders, cognitive impairment, mechanical ventilation. Patients with elective aneurysm coiling are being chosen because they require ICU level of care following their intracranial procedure, but do not have structural brain injury or ongoing sedation needs that might impact sleep measurements. Methods: Usual care: Patients are monitored every 15-30 minutes for up to 6 hours post-procedure, then Q1 or Q2 for up to 24 hours. If these patients remain stable, they are discharged home on post-operative day (POD) 1. Proposed Intervention: Enrolled patients will be randomized to Q1 or Q2 neurochecks following the institutionally required 6 hours of stable neurological and vascular checks. Once randomized, patients will undergo placement of electroencephalogram (EEG) with video, electrooculogram, and chin lead. The video EEG will be in place for at least 8 hours to include the overnight (10PM-6AM) time period. Following completion of the recording, the signals obtained will be reviewed by a blinded polysomnographic sleep technician for sleep characteristics including quantitative assessments of wakefulness, deep (N3) sleep, REM sleep, sleep efficiency, and sleep fragmentation and arousals. On POD1, patients and their nurse will fill out the Richards-Campbell Sleep Questionnaire to rate subjective sleep quality.
Study on Prognosis of Acutely Ruptured Intracranial Aneurysms
Aneurysmal Subarachnoid HemorrhageEndovascular Procedures3 moreThe SPARTA study is a prospective multicenter observational trial in the Netherlands with the aim of identifying the best clinical care in patients with aneurysmal subarachnoidal haemorrhage. Differences in outcome between surgical treatment and endovascular treatment will be explored. Furthermore, cost effectiveness and radiological prognostic factors will be examined.
Evaluation of Iliac and Renal Artery for Mechanism of Intracranial Aneurysm in ADPKD
Kidney Transplant; ComplicationsPolycystic Kidney Diseases2 moreADPKD is the most common form of hereditary kidney disease and is known to occur in 1 of 400 to 1000 population in the U.S. ADPKD consists of 2.8% of patients receiving kidney transplantation in our center. It is known that ADPKD is associated with vascular anomalies, including abdominal aneurysms, valvular anomalies and especially intracranial aneurysms. Intracranial aneurysms occur in 9~12% of the ADPKD population which is higher than 2~3% in the general population and is known to be associated with PKD1 or PKD2 heritage. Until now, most of the studies regarding intracranial aneurysms in ADPKD are conducted in animal models, and there are only few cellular studies conducted from human samples. While performing kidney transplantation to ESRD ADPKD patients, arterial tissues from nephrectomy specimens can be obtained. The objective of this study is to investigate the mechanism of intracranial aneurysm in ADPKD patients by analyzing iliac and renal artery characteristics.

Intracranial AneurysmThe Comaneci Embolization Assist Device is indicated for use in the neurovasculature as a temporary endovascular device used to assist in the coil embolization of wide-necked intracranial aneurysms with a neck width ≤ 10 mm. A wide-necked intracranial aneurysm (IA) defines the neck width as ≥ 4 mm or a dome-to-neck ratio < 2. The objective of the Postmarket Surveillance Plan is to assess safety and performance as used in postmarket clinical practice in the U.S.
