Summary
Transradial access for cardiac procedures is common, but radial artery spasm can be a problem. This study shows how a balloon-assisted technique and Sheathless EauCath can overcome spasm and perforation during these interventions.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Access Techniques
Background:
- Transradial access is increasingly used for percutaneous coronary intervention (PCI) and diagnostic coronary angiography due to reduced access site complications.
- Radial artery spasm, sometimes with perforation, is a frequent complication leading to conversion to femoral access.
Purpose of the Study:
- To demonstrate techniques for overcoming radial artery spasm and perforation during transradial procedures.
- To present the utility of the balloon-assisted technique and Sheathless EauCath in managing these complications.
Main Methods:
- Case presentation of two patients experiencing radial artery spasm with significant perforation during transradial procedures.
- Application of a balloon-assisted technique to manage spasm.
- Utilization of the Sheathless EauCath system to facilitate access despite complications.
Main Results:
- Successful management of radial artery spasm and perforation in both presented cases.
- Completion of diagnostic coronary angiography and/or PCI without conversion to femoral access.
- Demonstrated feasibility of the balloon-assisted technique and Sheathless EauCath in challenging radial access scenarios.
Conclusions:
- The balloon-assisted technique and Sheathless EauCath are effective strategies for managing radial artery spasm with perforation during transradial interventions.
- These methods can help preserve the benefits of transradial access by avoiding conversion to the femoral approach.

Assessment 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:

01:12Arteries of the Upper Limbs
3.2K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Apical-Radial (A-R) Pulse Assessment
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.

01:22Esophageal Perforation-I: Introduction
808
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

3.7K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
