Active clinical trials for "Aneurysm"

Observational, prospective, cohort study to evaluate, by an opportunistic screening program based on vascular ultrasound, the prevalence and characteristics of Abdominal Aortic Aneurysm (AAA) and Popliteal Artery Aneurysm (PAA) in a female population as well as the prevalence and characteristics of PAA in male population.

The purpose of this study is to assess the safety and effectiveness of the Artisse™ Intrasaccular Device in the treatment of bifurcating saccular intracranial aneurysms.

The HERCULES trial is a Randomized controlled clinical trial designed to prospectively compare endosuture aneurysm repair (ESAR) to standard endovascular aneurysm repair (EVAR) clinical outcomes in treatment of infrarenal abdominal aortic aneurysm (AAA) in subjects having wide proximal aortic neck diameters (≥ 28mm and ≤ 32mm).

Pre-emptive abdominal aortic aneurysm sac embolization during endovascular abdominal aortic repair for infrarenal abdominal aortic aneurysm - Randomized study

The goal of this clinical trail is to compare the difference between transradial access (TRA) and transfemoral access(TFA) for ruptured intracranial aneurysms embolization. The main question it aims to answer is: whether is TRA not inferior to TFA？ In the experimental group, the transradial access (TRA) was used, which was to puncture the radial artery and insert a radial sheath to establish a surgical pathway for embolization of the aneurysm; In the control group, transfemoral access (TFA) was used to embolize the aneurysms, which was to puncture the femoral artery and insert the femoral sheath to establish a surgical pathway for embolizing the aneurysms.The two groups of patients received an oral loading dose of aspirin (300mg) plus clopidogrel (300mg) on the day of surgery, while patients who were unable to take orally were given nasal feeding. During the operation, systemic heparinization was performed with a starting dose of 75U/kg intravenous injection, and the injection was halved every 1h until 1000U. After the operation, protamine neutralizing heparin (1mg protamine neutralizing 100U heparin) was used.

The goal of this clinical trial is to compare intracranial aneurysm patients. The main question it aims to answer are: Which heparinization regimen is most beneficial to patients during surgery for intracranial aneurysms. Participants will be randomized to different intraoperative heparinization regimens: (i) 50 U/kg intravenous (IV) at 1-h intervals reduced by half to a minimum of 1000 u/h; (ii) 60 U/kg IV at 1-h intervals reduced by half to a minimum of 1000 u/h; (iii) 70 U/kg IV at 1-h intervals reduced by half to a minimum of 1000 u/h. MRI will be performed within 72 h after surgery, and the DWI sequence of MRI will be analyzed. If there is a comparison group: Researchers will compare different intraoperative heparinization protocol groups to see which dose of intraoperative heparin has the best prognosis for use.

This study was designed to identify whether there is a measurable reduction in inflammation in walls of intracranial aneurysms with oral dimethyl fumarate.

The purpose of the proposed study is to investigate the usefulness of laser speckle contrast imaging (LSCI) compared to indocyanine green angiography (ICGA). We will collect data from a wide variety of neurovascular surgical procedures to determine when the technology is the most clinically useful. The intraoperative LSCI system provides high resolution images of blood flow in real-time without tissue contact and without the need for an exogenous contrast agent. Further study is needed to gain a better understanding of the use of the technique during surgery, but initial results suggest that the ability to identify blood flow changes with immediate feedback to the surgeon could be a significant advantage during many procedures.

A Blind-adjudication Multi-center Phase II Randomized Clinical Trial of Continuous Low-dose Intravenous Heparin Therapy in Coiled Low-grade Aneurysmal Subarachnoid Hemorrhage Patients with Significant Hemorrhage Burden. - STUDY IS TEMPORARILY SUSPENDED WITH PLAN TO RESUME SOON. NO SAFETY CONCERNS

The proposed study is a multi-center single arm retrospective and prospective data collection, of patients treated with the LVIS device of specific sizes of 3.5mm, 4.0mm, 4.5mm, 5.5mm with up to 5 years follow-up. Information collected during the study will be standardized across centers to include pre-treatment baseline characteristics of patients including aneurysm(s) symptoms, procedural information, prespecified clinical safety events of interest, and follow-up imaging, clinical visits or telephone calls.
