The VII annual transradial endovascular course (TREC-2020) took place in Kazan within 23-25 January. It is one of the greatest Russian symposia in interventional cardioangiology. Stanislav Sapozhnikov, MD, Interventional Cardiologist of the Department of X-Ray Endovascular Diagnostics & Treatment #1, Tyumen Cardiology Research Center, delivered an oral presentation.
Dr. Sapozhnikov presented the results of the research conducted at the premises of Tyumen Cardiology Research Center in 2019 within the joined session “Young generation in the Russian interventional angioangiology” of the Paris revascularization course and Association of young interventional radiologists and endovascular specialists.
He also explained: “We conducted pilot randomized study to define whether the introducer length influences the frequency of the blockage of the radial artery through which PCI is performed. Now radial arterial access (access through the artery in the forearm) is recommended as the standard approach for coronary angiography or stenting. However, despite its advantages, there are disadvantages as well. The most widespread complication is occlusion (total absence of the blood flow – blockage) of the radial artery. The risk of its progress lies in the range 1-10% as per different authors. Such a condition in future will discomfort or make impossible to perform another intervention. Interventional cardiology is increasingly leading among the methods of effective treatment of cardiovascular diseases, indications for interventions in patients with complex pathologies are expanding, but the principle of minimal trauma for the patient remains unchanged. We are also working in this direction and are constantly improving our methods. A study conducted by our scientific laboratory showed that the occurrence of occlusions does not depend in any way on the length of the conductor. We plan to study other criteria and continue to search for the safest operations.”
It should be noted that the presented study was the first work for Tyumen Cardiology Research Center registered on the World Clinical Research website and received positive feedback from European colleagues. In particular, the results were highly appreciated by S. Pancholi, the US cardiologist, who also specializes in the prevention of radial artery occlusion after transradial interventions. A feature of the conference was the live broadcast of a robot-assisted coronary intervention, which was performed in one of the best hospitals in India - Apex Heart Institute. Participants could observe in detail all stages of the operation in real time.
As in previous courses, topical issues related to intravascular imaging and physiology, innovations in endovascular surgery were also discussed in Kazan. Particular attention was paid to peripheral interventions, and in particular to neurointerventions. Lectures traditionally alternated with demonstrations of operations and new possibilities in the study of imaging and blood flow. All three days there was a broadcast of operations from different clinics. In total, more than 300 specialists from 10 countries of the world took part in the forum.
