NCT ID: NCT04269447 Enrolling by invitation - Aortic Aneurysm Clinical Trials

Prospective Aortic Biobank of POP-STAR

Start date: November 18, 2019
Phase:
Study type: Observational [Patient Registry]

The overall objective of the POP-STAR project is individualized surveillance for patients diagnosed with abdominal aortic aneurysms by means of more precise, patient-specific AAA growth prediction.

Non-invasive Aortic Aneurysm Tissue Characterization Using Wall Viscoelasticity

AAA multiphase
Start date: September 1, 2020
Phase:
Study type: Observational

Abdominal aortic aneurysm (AAA) is an abnormal dilatation of the aorta in the abdomen due to a wall weakening caused by atherosclerosis. While indications for a rupture intervention are based on AAA maximal diameter (MaxD) (5 cm), 23% of ruptured AAAs are less than 5 cm and in large AAAs, rupture rate could be lower than expected. We propose to expand and validate our vascular ultrasound elastography software to 3D. Strain maps generated from radiofrequency (RF) data acquired from 30 AAA patients with a matrix-array 3D probe will be registered to conventional CT (phase 1) and validated to a biomechanical for characterization of AAA wall, assessing vulnerability and influence of surrounding tissues (phase 2). At the end of the project, we will have analyzed 3D strain maps to improve patient selection before surgery.

Open Versus Endovascular Repair of Abdominal Aortic Aneurysms

Start date: January 1, 2018
Phase:
Study type: Observational

This is an observational retrospective cohort study of all patients consecutively submitted to elective abdominal aortic aneurysm surgery repair at a tertiary referral centre between 2009 and 2015. Patients were excluded if they were non-elective cases or had complex aortic aneurysms (juxta-renal, thoraco-abdominal or thoracic). Differences between both groups of repair were assessed, as well as short- and long-term complications including medical complications, duration of hospital stay, major cardiovascular events, mortality and vascular reintervention.

The British Society of Endovascular Therapy ConformabLe EndoVascular Aneurysm Repair Registry

BSET-CLEVAR
Start date: June 26, 2019
Phase:
Study type: Observational [Patient Registry]

The purpose of the BSET-CLEVAR Registry is to collect device-specific performance outcomes of the GORE® EXCLUDER® Conformable AAA Endoprosthesis with ACTIVE CONTROL System (EXCC device) in routine clinical treatment of patients with abdominal aortic aneurysm in the UK. The novel EXCC device is an evolution of an established device allowing active shaping to conform to the specific patient aortic neck anatomy, with more accurate deployment, potentially greater neck coverage and better long term fixation/sealing. This may translate to improved effectiveness of this device over time, reducing the need for any further procedures. The primary aim of this study is to assess the degree of neck coverage by the EXCC device. The British Society of Endovascular Therapy (BSET) has received funds from the stent manufacturer (W.L. Gore & Associates, Inc.) to conduct this study. BSET and the Sponsor (Imperial College London) have full responsibility for the design, conduct, analysis and reporting of the study.

NCT ID: NCT03298477 Active, not recruiting - Clinical trials for Abdominal Aortic Aneurysm Without Rupture

EVAS2 IDE Prospective, Multicenter, Single Arm Safety and Effectiveness Confirmatory Study

EVAS2
Start date: December 1, 2017
Phase: N/A
Study type: Interventional

Prospective, multicenter, single arm study with consecutive, eligible subject enrollment at each site. All subjects will undergo the Endovascular Aneurysm repair procedure with the Nellix System.
