NCT ID: NCT06394271 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Early Endovascular Repair Versus Surveillance for Women With Small Abdominal Aortic Aneurysm

WARRIORS
Start date: October 1, 2024
Phase: N/A
Study type: Interventional

Elective Abdominal Aortic Aneurysm (AAA) repair is offered when the risk of rupture exceeds the risk of surgery. Women (versus men) have a four-fold higher risk of AAA rupture but almost double the operative mortality. It is unknown whether the current 5.5cm diameter AAA repair threshold, derived from randomised trials including only 4% women, is applicable to women. Therefore, should women have their aneurysms repaired electively at smaller diameters than men to improve their AAA-related survival and quality of life? WARRIORS is an international randomised controlled trial of early elective endovascular repair versus routine surveillance in women (n=1112) with small asymptomatic AAA (4-5.4cm diameter), nested within a registry of non-participants. The surveillance group will be offered repair for rupture or upon reaching the 5.5cm threshold. Randomisation will be 1:1 stratified by country, age, and aneurysm diameter. The trial is powered for aneurysm-related mortality or rupture at 5 years. Quality-Adjusted-Life-Years is a major secondary outcome. Other outcomes include: operative mortality and complications, anxiety, major cardiovascular adverse events, and cost-effectiveness. Quality-of-life and anxiety questionnaires and "standard-of-care" using routine data will be collected. The trial aims to progress health equity through provision of evidence for sex-specific clinical guidelines for AAA repair.

CArbohydrate Loading in Aortic Surgery

Start date: June 1, 2024
Phase: N/A
Study type: Interventional

The adverse effects of overnight fasting before surgery have been well-documented in the contemporary literature. Still, due to the possibility of pulmonary aspiration of gastric contents, many clinicians worldwide still employ this practice. On the other hand, the benefits of preoperative oral carbohydrate loading (OCHL) have been shown in various patient groups. Studies examining the usefulness of preoperative OCHL in aortic surgery are lacking. In particular, no randomized control trials have specifically examined the impact of preoperative OCHL on the postoperative course in patients undergoing open abdominal aortic surgery.

Shockwave TEVAR is a nonrandomized, prospective, international, multi-center, PMCF, obervational study. The aim of this study is to evaluate the outcomes of the Shockwave™ Peripheral Intravascular Lithotripsy Balloon (Shockwave Medical Inc.) in the routine treatment of hostile iliac accesses during TEVAR and F/BEVAR.

NCT ID: NCT06081153 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Mechanistic Clinical Trial of PCSK9 Inhibition for AAA

Start date: July 1, 2024
Phase: Early Phase 1
Study type: Interventional

The goal of this mechanistic clinical trial is to assess whether lowering the low-density lipoprotein cholesterol (LDL-C) levels in the blood with the injections of the medication evolocumab will have any effect on the tissue or cells of patients with abdominal aortic aneurysm (AAA). Researchers will compare participants receiving evolocumab injections to participants receiving placebo injections to see how the tissue and cells of the aorta are affected by changes in LDL-C levels.

The PREHAAAB Trial: Multimodal Prehabilitation for Patients Awaiting Open Abdominal Aortic Aneurysm Repair

Start date: September 2023
Phase: N/A
Study type: Interventional

An abdominal aortic aneurysm is a condition where the major artery in the abdomen becomes larger than usual. Over time, as it continues to grow, the wall of the artery weakens and there is a risk that the artery can burst causing internal bleeding and death. Aortic aneurysms are fixed when they reach a certain size to prevent that outcome. The surgery to fix them is a major, high-risk surgery that is associated with a lot of complications and a slow recovery back to normal. The time between diagnosis and surgery is called the pre-operative period and is a key time to optimize a patient's health in order to ensure the best possible outcomes following surgery. This study will look at whether a multidisciplinary pre-operative program that involves exercise training, nutritional advice and supplementation, and psychosocial support will reduce complications following surgery. This program should decrease complications and speed up a patient's recovery back to normal after surgery. It is also a way for patients to take ownership of their disease and play an active role in their health care journey. The benefits from this program will go beyond the pre-operative time frame, as the habits and knowledge gained will improve their health over their lifetime. This study will also assess the economic impact and cost of a program like this.

Pre-emptive Abdominal Aortic Aneurysm Sac Embolization During EVAR

Start date: November 1, 2024
Phase: N/A
Study type: Interventional

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

NCT ID: NCT05361772 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Low-dose Colchicine Inhibit Abdominal Aortic Aneurysm Growth Trial

COIN
Start date: June 1, 2022
Phase: N/A
Study type: Interventional

COIN trial is a a prospective, randomized, placebo-controlled, double-blind, multicenter clinical study. Approximately 230 patients with small abdominal aortic aneurysms (AAA) will be randomly allocated to low-dose colchicine group or placebo group. All study patients will be followed up in the outpatient clinic every 3 months and undergo CTA scans after 24 months from randomization. The primary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA diameter. The secondary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA volume, reduce the incidence of clinical outcomes associated with AAA, reduce the incidence of major adverse cardiovascular events and all-cause mortality.

Sex-specific Differences in the Stress Response to Abdominal Aortic Aneurysm Repair

SSStressAAA
Start date: February 1, 2022
Phase:
Study type: Observational

It is recognised that women are at greater risk of death, complications and longer hospital stay following intact abdominal aortic aneurysm (AAA) repair, and the reason for this is not yet established. This disparity in outcomes for women compared to men is also recognised in other forms of cardiovascular surgery, which raises the question of whether women and men are reacting differently to the stress of operative repair. This study aims to examine whether there are differences baseline stress markers and in the stress response to AAA repair between men and women. It will also examine whether markers of stress are associated with poor clinical outcomes and slower recovery (indicated by longer hospital stay). The study will take the form of an observational cohort study. It will not alter any of the treatment that men and women receive, but will monitor their stress levels using physiological markers (through ECG (electrocardiogram) monitoring using a non-invasive holter, biochemical markers using blood samples (which will be taken at the same time as routine testing, so as not to require further invasive procedures), and psychological testing, using short forms that the patient will be able to fill out independently at different stages of their recovery. Clinical data will be used to look for relevant factors (clinical history or medications) which may alter the stress markers we are observing, and to compare outcomes with markers of stress. Patients will be asked for their consent to share their data with the research team in order to participate in the study. It will be made clear that there will be no change in their clinical or operative management if they participate in the study and they will be able to withdraw consent for further participation at any time.

NCT ID: NCT05072509 Not yet recruiting - Clinical trials for Abdominal Aortic Aneurysm

Assessment of the Endovascular Aortic Aneurysm Repair's (EVAR) Main Body Lateral Movement Impact on the Rate of Reintervention After AAA's Treatment

COLONEA
Start date: February 1, 2022
Phase:
Study type: Observational

The strength of movement which are applied on the EVAR are not only cranio-caudal but also lateral. The movement of the EVAR's body within the aneurysm could be an instability's criteria of the EVAR. The investigators would like to show that this lateral movement is a risk factor of reintervention they should follow and suggest a reinforced medical follow-up to avoid complications.
