Abdominal aortic aneurysm

This trial is evaluating a new device called the Bifurcated Multilayer Flow Modulator (BMFM) for treating abdominal aortic aneurysms that involve the iliac arteries. The device is designed to be implanted inside the blood vessel to help stabilize the aneurysm and prevent it from …

This study collects follow-up data from about 300 people who have already received a stent-graft to repair an abdominal aortic aneurysm (AAA). The goal is to assess how safe, effective, and durable the repair is over time. Participants had an AAA larger than 4 cm or one growing r…

This trial tests a special stent graft system designed to repair a complex type of abdominal aortic aneurysm that involves the arteries to the kidneys and gut. The device is placed inside the aorta using a minimally invasive procedure, aiming to seal the aneurysm while keeping bl…

This study followed 48 people who received the Nellix system, a device that seals abdominal aortic aneurysms from the inside using stents and polymer-filled bags. Researchers tracked how well the device worked right after the procedure and for up to 5 years. The goal was to see i…

This study tested a device called the Nellix system to repair a bulging blood vessel (aneurysm) in the belly without open surgery. 98 people with large or growing aneurysms took part. The goal was to see if the device is safe and works well at keeping the aneurysm from bursting o…

This early feasibility study tested a 3D holographic guidance system to help surgeons place stent grafts during endovascular aortic repair (EVAR) for abdominal aortic aneurysms. Two patients participated, and the system was used alongside standard X-ray imaging to confirm correct…

This registry tracked over 1,000 patients who received the Heli-FX EndoAnchor device during endovascular repair of aortic aneurysms. The device is designed to help hold the endograft in place and prevent leaks. Patients were followed for up to 5 years to see how safe and effectiv…

This study looked at how well a special stent (the Gore IBE device) works in real-world use for people with bulging blood vessels (aneurysms) in the belly or pelvis. Researchers tracked 100 patients who already had the device implanted to check if it stayed open and kept the aneu…

This study tested a specially designed stent-graft for people with abdominal aortic aneurysms (a bulging blood vessel in the belly) that have a difficult shape near the kidney arteries. Fifty patients received the custom device to see if it could safely seal the aneurysm and keep…

This study tested whether a special ultrasound with contrast dye can be as good as CT scans for checking aortic endoprostheses after abdominal aortic aneurysm repair. Forty patients received both an ultrasound and a CT scan after surgery. The goal was to see if ultrasound could d…

This study tested whether giving vascular surgery patients access to a website with educational videos could reduce their anxiety before the operation. 250 patients were split into two groups: one got the videos, the other did not. Researchers measured anxiety using a simple 0-to…

This study looked at 405 patients who had a minimally invasive procedure to fix an abdominal aortic aneurysm. Researchers reviewed medical records to see how often complications occurred and which imaging test—ultrasound or CT scan—was better at finding them. The goal was to impr…

This completed registry followed 300 patients with abdominal aortic aneurysm who were treated with the Nellix® Endovascular Sealing System across 30 international centers. The goal was to see how well the device performs in everyday medical practice, measuring safety and effectiv…

This study tested whether a special 3D X-ray done in the operating room can replace standard CT scans after repairing an abdominal aortic aneurysm. 427 patients were randomly assigned to either the new 3D scan or the usual approach. The goal was to see if the new method reduces r…

This study looked at 80 adults having heart valve or aortic surgery to find out how long a special heart protection solution (Del Nido cardioplegia) keeps the heart safe during surgery. Researchers took blood samples at set times to see when heart injury began. The goal was to le…

This study looked at 511 patients who had surgery to repair an abdominal aortic aneurysm (a bulging blood vessel in the belly) to find out what makes some people develop dangerously low blood pressure after the operation. The researchers reviewed medical records from 2013 to 2021…

This study looked at 659 patients who had surgery to fix an abdominal aortic aneurysm. Researchers compared two types of scans—CT and ultrasound—to see which one is better at finding problems like leaks or blockages after the repair. The goal was to find out if ultrasound could b…

This study created a large registry of 394 patients who had surgery for an abdominal aortic aneurysm (AAA) in North Texas hospitals. The goal was to track survival, need for repeat surgery, and risk of rupture over time. By collecting this data, doctors hope to improve the qualit…

This study looked at whether placing a mesh during abdominal aortic aneurysm repair could prevent incisional hernias later. Fifty patients were split into two groups: one got mesh reinforcement, the other standard closure. After follow-up, the mesh did not show a clear benefit in…

This study looked back at 268 people who had a wide-neck abdominal aortic aneurysm repaired with the Endurant stent graft. Researchers checked how many needed additional procedures within one year and up to ten years after surgery. They also tracked any leaks around the graft. Th…

This study looked at whether natural aging of proteins in blood vessel walls contributes to the development of aortic aneurysms. Researchers measured skin autofluorescence and collected blood and skin samples from 24 patients undergoing surgery for abdominal aortic aneurysms. The…

This study involved 30 adults undergoing open surgery on the abdominal aorta. Researchers used cameras and CT scans to measure the working space inside the body during surgery. The goal was to create a mathematical model that links a patient's body shape and incision size to the …
