Insights
Transradial access (TRA) offers benefits over transfemoral access for cardiac procedures, reducing complications and improving survival. This review details preventing, identifying, and managing TRA complications for better patient outcomes.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Transradial access (TRA) is increasingly preferred for coronary angiography and percutaneous coronary intervention.
- TRA offers advantages over transfemoral access, including reduced vascular and bleeding complications.
- A survival benefit has been documented for ST-segment-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention via TRA.
Purpose of the Study:
- To summarize contemporary techniques for preventing, identifying, and managing transradial access complications.
- To provide guidance on minimizing adverse events associated with TRA.
Main Methods:
- Review of current literature and best practices for transradial access.
- Categorization of TRA complications into intra- or postprocedural and bleeding or nonbleeding issues.
- Emphasis on contemporary access techniques to limit arterial injury.
Main Results:
- Major TRA complications like radial artery perforation and compartment syndrome are rare but can be severe.
- Nonbleeding complications, such as radial artery spasm and occlusion, are more frequent but typically less morbid.
- Prompt identification and management are crucial for severe complications.
Conclusions:
- Effective strategies for preventing TRA complications are essential.
- Understanding and managing TRA-related issues can improve procedural safety and patient outcomes.
- Contemporary techniques play a vital role in minimizing TRA complications.
Abstract:
Transradial access (TRA) is favored over transfemoral access for performing coronary angiography and percutaneous coronary intervention due to the reduced risk for vascular and bleeding complications and the documented survival benefit in ST-segment-elevation myocardial infarction patients who undergo primary percutaneous coronary intervention. TRA complications can be categorized as intra- or postprocedural and further categorized as related to bleeding or nonbleeding issues. Major intra- and postprocedural complications such as radial artery perforation and compartment syndrome are rare following TRA. Their occurrence, however, can be associated with morbid consequences, including requirement for surgical intervention if not identified and treated promptly. Nonbleeding complications such as radial artery spasm and radial artery occlusion are typically less morbid but occur much more frequently. Strategies to prevent TRA complications are essential and include the use of contemporary access techniques that limit arterial injury. This document summarizes contemporary techniques to prevent, identify, and manage TRA complications.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
