Randomized comparison of radiation exposure in coronary angiography between right conventional and left distal radial artery approach

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The left snuffbox approach is expected to be easier to perform because of less severe tortuosity of the clavicle artery. However, clinical validation of the snuffbox approach was not completed compared with the conventional radial approach. Especially, there is no clinical data on the comparison of the radiation dose in both approaches. To date, there have been some studies on the radiation dose between the left and right radial artery and femoral artery puncture site, but no studies have been conducted on the left snuffbox approach.

The purpose of this study was to compare the radiation doses of the two interventional radiologists by randomly assigning coronary angiography to the left snuffbox approach and right conventional radial approach.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Placebo Comparator: Right conventional radial approach
After local anesthesia on right wrist area with lidocaine hydrochloride using a 26 gauge needle, the puncture is performed using a 20 gauge needle with the through-and-through puncture technique or a 21 gauge open needle with anterior wall puncture technique. After the successful puncture, 0.025-inch straight wire or 0.018-inch hair wire are inserted, followed by insertion of the 5Fr. radial sheath (Prelude® Radial; Merit medical, UT, USA or Radifocus® Introducer II or Glidesheath Slender®; Terumo Corporation, Tokyo, Japan).
Procedure: artery puncture and coronary angiography
We will perform coronary angiography through a Judkins 5 French diagnostic catheter and will take a basic view. At the end of the examination, the radial sheath is removed and the right conventional radial approach is performed for about 4 hours and the left snuffbox approach for about 2 hours using the compressive bandage method. The hemostatic device will use ez ClotRadial® (SOYEON medical Co., Ltd., Wonju, Korea).
Active Comparator: Left distal radial approach
After local anesthesia on left anatomical snuffbox area with lidocaine hydrochloride using a 26 gauge needle, the puncture is performed using a 20 gauge needle with the through-and-through puncture technique or a 21 gauge open needle with anterior wall puncture technique. After the successful puncture, 0.025-inch straight wire or 0.018-inch hair wire are inserted, followed by insertion of the 5Fr. radial sheath (Prelude® Radial; Merit medical, UT, USA or Radifocus® Introducer II or Glidesheath Slender®; Terumo Corporation, Tokyo, Japan).
