Scientists from the USA have created a device that allows for a detailed examination of the anatomical and molecular structure of blood vessels, as well as identifying the sites of thrombus formation. The formation of thrombi in blood vessels can lead to heart attacks, which often end in death. This is especially dangerous in the case of an implanted stent, which is a cylindrical frame to prevent vascular stenosis.
Research has shown that about 2% of people with stents in their coronary vessels are at high risk of developing a myocardial infarction. Therefore, scientists began to develop a device that would help in timely prevention of the formation of obstacles in the blood flow. Externally, this device resembles a regular catheter.
Micrographs are obtained using two technologies: the first allows one to see the anatomical structure of the vessel walls in high quality, the second allows one to determine the molecular composition of tissues previously labeled with fluorescent markers.
As a result, the doctor can see a three-dimensional color image that shows where fibrin, the main component of a thrombotic clot, has accumulated before it causes any obstruction to blood flow in the vessels.
Testing of the new development was successful on rabbits, and the convenient design of the device will allow its wide use in medical practice.
