Endovascular aneurysm restore is a minimally invasive method for the therapy of belly aortic aneurysms—life-threatening bulges within the aorta’s belly part. Nevertheless, it carries the chance of recurrence owing to endoleaks after stent graft implantation, necessitating common follow-up, particularly since these leaks can’t be simply linked to particular signs.
Sadly, solely imaging-based monitoring similar to computed tomography angiography or magnetic resonance imaging is on the market for the time being. This typical follow-up protocol is commonly periodic, dangerous resulting from radiation publicity, exhausting to entry, costly, or inaccurate.
In a current breakthrough, a staff of researchers led by Dr. Yei Hwan Jung, an affiliate professor within the Division of Digital Engineering in addition to the Division of Synthetic Intelligence Semiconductor Engineering at Hanyang College, South Korea, has proposed a novel ultrathin versatile sensor inserted endovascularly with a stent to detect Kind-I endoleaks with the utmost rupture danger. Their findings have been made accessible on-line and revealed within the Science Advances journal on October 1, 2025.
Dr. Jung additional highlights the primary contributions of their research. “We have seamlessly integrated the ultrathin sensor onto a stent graft without compromising its original form or function. The sensor is robust enough to withstand the dynamic process of being crimped into a catheter and deployed inside the vessel.”
That is the core innovation that transforms a passive implant into an lively, sensible monitoring machine, enabling proactive detection of the silent however doubtlessly deadly danger of endoleaks for aneurysm sufferers.
The researchers experimentally validated the novelty of their next-generation know-how. They discovered that the sensor doesn’t induce blood leakage and displays long-term stability and performance below vascular and dynamic circumstances.
Dr. Jung factors out the immense potential of their work and says, “The first real-life software is for all sufferers present process endovascular aneurysm restore. This sensor would turn out to be an integral a part of the stent graft machine itself, serving as a built-in security examine. Its instant use is to supply steady post-operative monitoring, catching Kind-I endoleaks the second they start.
“Beyond this, the core technology—a flexible, biocompatible sensor platform for detecting fluid leakage—could be adapted for other medical procedures. For instance, it could be used to detect subtle flow changes or leaks around stents used for treating peripheral artery disease, or in arteriovenous grafts for hemodialysis, contributing to the long-term success of these procedures.”
Over the subsequent 5 to 10 years, this know-how has the potential to turn out to be the brand new commonplace of look after aneurysm therapy. Stent grafts with out built-in, real-time monitoring might turn out to be out of date. The longer-term imaginative and prescient is a future the place these “smart” implants are linked to telemedicine platforms. A affected person’s stent might wirelessly transmit its standing to their smartphone and, in flip, to their physician, enabling steady distant monitoring. This could drastically scale back the necessity for hospital visits, particularly for the aged or sufferers residing in rural areas.
Total, this innovation facilitates wi-fi monitoring of endoleak standing, permits well timed intervention, and extremely enhances postoperative outcomes by lowering the chance of recurrent aneurysms, furthering the sector of medical science and well being care.
