Active clinical trials for "Aneurysm"

The goal of this observational study is to perform an in vivo feasibility study using real time (3D) ultrasound based vector flow imaging in 10 AAA patients (5 with intraluminal thrombus and 5 without intraluminal thrombus). Furthermore, the investigators will investigate the added value of contrast microbubbles in these high framerate, plane wave ultrasound measurements. Included patients will undergo ultrasound scanning of their AAA, using multiple ultrasound sequences. Sequences will be tested with and without the addition of ultrasound contrast microbubbles.

The 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.

The ENDOBARC-S post-market clinical follow-up study is undertaken to evaluate the prevention of death related to aortic arch pathologies when treated by branch stent graft systems (Nexus stent-graft system®, Relay Branch® or Zenith arch branch graft®), with proximal landing at zone 0. The secondary objective is to evaluate the safety and clinical performance of the studied devices.

To determine safety and occlusion rates when second-generation hydrogel coils are used in the treatment of ruptured intracranial aneurysms.

The purpose of the post-market study is to assess the clinical outcomes, safety, and performance of the Endurant Chimney Graft Technique (Endurant Stent Graft Systems used with a balloon-expandable covered stent graft) for treatment of juxtarenal aortic aneurysms with a short infrarenal neck in a real world setting.

ADPKD 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.

The BIOMArCS-AAA study aims to investigate the associations of (temporal patterns of) blood biomarkers with aneurysm growth in patients with abdominal aortic aneurysm (AAA), with particular attention to biomarkers that have demonstrated prognostic value for adverse disease outcomes in coronary artery disease and biomarkers for the main genetic pathways associated with AAA.

Although open repair (OR) is currently reported as the gold standard of treatment, fenestrated endovascular repair (FEVAR) is being increasingly applied for the treatment of proximal abdominal aortic aneurysms (p-AAA) such as hostile-necked, juxta-, para- and supra-renal aortic aneurysms.1 Nevertheless, advantages of FEVAR in terms of lowering postoperative complications, should be balanced with the need of both complex device configurations and operators with large endovascular expertise. The aim of this study is to report the experience of Data from patients treated will be prospectively collected. All post-operative results will be recorded. Major adverse event (MAE) are defined as the presence of one of the following: all-cause mortality, bowel ischemia, myocardial infarction, paraplegia, respiratory failure, stroke and renal insufficiency. Furthermore, the pre-operative contrast-enhanced computed tomography scans (CTA) of all patients, stored in the hospital PACS, will be analyzed on the dedicated workstation with OsiriX software (Pixmeo sarl, Bernex, Switzerland) currently employed in our Unit for imaging assessment. Patients will undergo standard control with the execution of a Doppler ultrasound and creatinine serum levels at 1, 6, 12, 24, 36, 48 and 60 months. A CTA will also be performed at 12 months as per standard clinical practice. of p-AAA treatment.

Comparison of elective infrarenal aneurysm surgery with open and endovascular technique, respectively, for subclinical ischemic myocardial injury detectable with troponin T and/or 3-channel Holter ECG with ST analysis

This is a prospective, non-randomized, single center, data collection study of patients treated with open surgical repair (OR) for complex aortic aneurysms (CAAs).
