Use of Various Types of Introducers in Conventional Radial Access

The purpose of this intervention study is to compare different types of radial introducers used in traditional radial access in terms of the incidence of complications. The main questions it aims to answer are: 1. Does a smaller outer diameter of the introducer reduce the risk of complications associated with radial access? 2. Does the presence of an outer hydrophilic coating on the introducer reduce the risk of complications associated with radial access? 3. Does the use of an introducer with a smaller outer diameter and an outer hydrophilic coating reduce the risk of complications associated with radial access? The researchers will compare the number of complications associated with radial access when using conventional diameter, uncoated radial introducers, conventional diameter introducers with an outer hydrophilic coating, or reduced outer diameter introducers with an outer hydrophilic coating. During the scheduled revascularization procedure, the participants will undergo radial artery catheterization using one of the types of introducers. Complications from the radiation access will be recorded by doctors within 72 hours after the intervention.
