About this study

Official title: A Prospective Registry to Assess the Safety and Efficacy of Distal Radial Access (SAFE-BOX)

A Prospective Registry to assess the Safety and Efficacy of Distal Radial Approach

Read the detailed description

Anaphylactic radial approach is now recognized as a basic technique in coronary artery procedures. The main advantage is increased stability due to the reduction of massive bleeding and increased patient comfort because it can move immediately after the procedure. The operator prefers access to the right radial artery because of the comfort of performing the procedure on the right side of the patient. However, the operator should frequently replace it with a left radial artery approach for various reasons, including 1) closure of the right radial artery, 2) difficulty accessing the coronary artery due to severe gambling of the radial artery, and 3) hemodialysis of the right radial artery.

As for prognosis, the left and right radial artery approaches are similar. However, the left radial artery approach is bound to experience anthropological discomfort in which the operator has to lean toward the patient. An easy solution is the approach from the anatomical left snuff box located on the back of the hand to the distal radial artery. Recently, the left snuffbox approach has been reported, and attempts are increasing in many countries. However, it is true that there is still a difference in diameter of the radial artery through the distant radial artery approach and concerns about percutaneous coronary intervention through this compared to the classical radial artery approach. Recent studies have published studies on the stability and effectiveness of distant radial artery approaches, but they are still small, and studies on specific subgroups are very scarce. Furthermore, data on the current status and performance in Korea so far is very scarce. Therefore, through this study, we would like to systematically collect and analyze data on the status and performance of the approach through the distant radial artery approach to find out the stability and effectiveness of various patient groups, treatment methods.

Questions about this trial

What is this clinical trial studying?

An observational study of Safety and Efficacy, run by Yonsei University at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 24 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Success rate of examination and procedure (time frame: through procedure completion, up to 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Apr 2026.
