Evaluation of Aortic Aneurysms With Focus on Wall Stress and Wall Rupture Risk

Aortic Aneurysm

Retrospective study to evaluate the impact of computational wall stress analysis based on computed tomography (CT) of ruptured and not-ruptured aortic aneurysms as an additional predictor for rupture with dedicated software.

Dynamic Contrast-Enhanced Magnetic Resonance Imaging Analysis for Prognosis of Intracranial Dissecting...

Dissecting Aneurysm of Cerebral Artery

This study will evaluate the feasibility to predict the prognosis of IDA with IMH by DCE-MRI and provide theoretical basis for the prognosis and intervention of the disease.

Evaluation of Adjunctive EndoAnchors for EVAR and TEVAR

Aortic AneurysmThoracic Aortic Aneurysm

EndoAnchors (Heli-FX device, Medtronic, Santa Rosa) have beed described to improve fixation (mimicking an open surgical anastomosis) during or after EVAR/TEVAR. The investigators want to describe the outcomes of all consecutive patients treated with this device (retrospective and prospective data - observational study)

Reference Values of Circulating Endothelial Progenitor Cells

Aortic Aneurysm

Circulating endothelial progenitor cells CD34+144+CD14- et CD34+VEGF-R2+CD14- have been shown to be inversely correlated to aortic aneurysm size. However reference values have not yet been determined. This study is aimed to determine reference values of CD34+144+CD14- et CD34+VEGF-R2+CD14- in healthy men and women blood donors.

Validation of the Cheetah NICOM by Comparison to TEE During Open Vascular Surgery - Pilot Study...

Aortic AneurysmPeripheral Arterial Disease

The Cheetah NICOM is a non-invasive cardiac output monitor that has been validated in various clinical contexts but not during the occlusion of major arteries, as takes place in vascular surgery. The present study will evaluate the precision and validity of the measures taken by the device during open vascular surgery procedures. The measurements will be compared to the those calculated by transesophageal echocardiography at various key points during the surgeries. The validity of the cardiac output, stroke volume and stroke volume variation measurements will be evaluated, as well as the device's ability to track rapid changes in cardiac output.

Investigation of the Cerebrospinal Fluid and Further Tissue Samples for Biomarker Indicating Spinal...

Thoracoabdominal Aortic Aneurysm

Patients with a thoracoabdominal aortic aneurysm in need of an endovascular or open operative restructuring will be asked to participate in this study. After obtaining written consent a central venous catheter and a liquor drainage will be routinely placed during surgery. The catheter and the drainage will stay in the patients for at least 72 hours postoperatively. In total, nine measurements of the liquor and serum will be performed within a week in order to determine the following parameters: neuropeptide P, neuropeptide Y, neurofilament triplet protein (NFL), S100B, glial fibrillary protein (GFAp), lactate, glucose, or oxygen.

The Prospective Cohort Study on the Benefit-risk of Antithrombotic or Anticoagulant Therapy in Patients...

Intracranial AneurysmNatural History2 more

This is a registry study of the natural course of unruptured intracranial aneurysms (UIA). In addition, the investigators will analyze the benefit-risk of antithrombotic or anticoagulant therapy in patients with unruptured intracranial aneurysms associated with ischemic heart disease or ischemic cerebrovascular disease. The investigators aim to use research data to create a China national database of UIA

Screening Intracranial Aneurysms With Magnetic Resonance Angiography (MRA) in China

Intracranial Aneurysm

The Chinese Cerebral Aneurysms Survey is a continuing prospective study among middle-aged and older individuals (35 - 75 years) that aims to determine the prevalence of cerebral intracranial aneurysms in the general population with MRA at 3.0 Tesla (T).

EndoSure Sensor for Long-term Follow-up After Endovascular AAA Repair

Aortic AneurysmAbdominal

The purpose of this study is to collect and compare EndoSure and EndoSure s2 Wireless AAA Pressure Sensor measurements with measurements from CT scan imaging, ultrasound, and other tests used to measure your AAA sac size and endoleaks following AAA repair, and during follow-up visits with your physician. An antenna is held over the patient's abdomen to measure pressure inside the aneurysm sac. The reading does not cause any discomfort, and dye or radiation is not needed to take the pressure measurement. To qualify, the patient must have a previously implanted EndoSure Sensor.

Treatment of Popliteal Aneurysms With VIABAHN Stent Graft in Elective Surgery

Popliteal Aneurysm

This multicentric, prospective study will evaluate the medium-term outcomes of patients implanted with GORE VIABAHN® stent grafts for popliteal artery aneurysms in scheduled elective surgery with the registry of the Research in Vascular Surgery University Association (AURC)
