An abdominal aortic aneurysm is a balloon-like bulge in the aorta often linked to hardening of the arteries. It is a dangerous condition. If it bursts, it’s usually deadly. But tracking aneurysms may soon be easier. In the past, a “stent” was placed in the artery to keep blood from accumulating in the aneurysm. The size of the bulge was monitored through lengthy and expensive CT scans every six months.
Now researchers, led by Takao Ohki of Montefiore Medical Center in New York, are testing the “EndoSensor,” a device that allows doctors to measure pressure, which is a key factor in preventing ruptures. It’s implanted near the stent in a minimally invasive procedure. To monitor the aneurysm, a doctor waves an electronic wand over the abdomen. The wand picks up radio signals from the sensor, which are translated into a pressure reading. Since there’s no radiation, the aneurysm can be monitored more often, which allows doctors can detect changes sooner. If pressure is high, the stent may need to be replaced. The “EndoSensor” could be available later this year. Live long and prosper.
