Scientists from our Research Center (a branch of Tomsk NRMC) have patented a method for endovascular treatment of thrombotic occlusion of autovenous aortocoronary bypass grafts in patients with acute ST-segment elevation myocardial infarction.
The authors of the patent are Ivan Bessonov, MD, Ph.D. , The head of the laboratory of X-ray endovascular me diagnostics and treatment of the Tyumen Cardiology Center, and Stanislav Sapozhnikov, MD, Junior Scientific Researcher of the laboratory of instrumental diagnostics of our Center.
The procedure consists in deep immersion of a catheter designed for contrasting into a thrombosed shunt. In the future, this catheter is used to aspirate (remove) blood clots from the shunt with an ordinary syringe. According to the scientists, this solution is simple, but very effective, since the lumen of catheter allows large blood clots to be aspirated. Specific devices for this have not yet been developed. Moreover, the presence of a large volume of thrombotic masses is characteristic feature for acute occlusion of venous coronary artery bypass graft.
Stanislav Sapozhnikov shared, that number of patients with myocardial infarction associated with acute occlusion of a venous coronary artery bypass graft was not so large and amounts to 2-5 people per year. The low frequency of emergency calls of such patients was associated, first of all, with the mild symptoms of the course of the disease. However, such cases were associated with high risks of an unfavorable prognosis.
The proposed method can be used in all patients with myocardial damage caused by acute coronary artery bypass graft occlusion. The main advantage of the method is its efficiency and minimal complications after surgery. In addition, risk of developing hemorrhagic complications, characterized by increased bleeding, is reduced.
Clinical trials have already been carried out. With adherence to proposed technique, it was possible to successfully aspirate thrombotic masses from the venous shunt and restore adequate blood flow. The postoperative period lasted without complications, and patients were discharged for outpatient follow-up as early as 5 days after surgery. Currently scientists are actively spreading information about the patented technique among colleagues.
