DIstal vs Proximal Radial Artery Access for Cath

2020-03-27 03:25:32 | BioPortfolio


This single-center, prospective, randomized study will evaluate distal radial artery (dRA) vs. proximal radial artery access (pRA) in regards to hand function and radial artery occlusion.


Primary objective is to evaluate hand function following distal radial artery access compared to proximal artery access in patients undergoing cardiac catheterization.

Hand function will be assessed by:

- QuickDASH questionnaire

- Hand grip test

- Thumb forefinger pinch test utilizing a pinch gauge

Secondary objectives: Vascular access success rates, hematoma, bleeding, complications of vascular access and radial artery occlusion.

Distal Radial Artery Approach to Prevent Radial Artery Occlusion (DAPRAO)

The main complication of transradial intervention is radial artery occlusion (RAO). This is relevant because it limits the radial approach for future interventions and disables this condui...

Distal vs Proximal Radial Approach for Coronary Interventions

The distal radial approach ('snuff box' / fossa radialis) has become as valuable as the 'classical' radial approach for coronary angiography and interventions. Up to now, the success of th...

Observational Study of Hand Function After Distal Transradial Access for Angiography

Traditionally, coronary angiograms are performed through the radial artery which is accessed above the palm of the 'right' hand. In recent years, some cardiologists are performing this pro...

The Distal (SnUffbox) Versus Proximal Radial artERy Access for Coronary Angiography and Interventions Registry (SUPER-Prospective)

The study team aims to perform a prospective observational case series of one hundred consecutive distal radial artery heart catheterizations to evaluate the safety and feasibility of dist...

CORonaRy Angiography and intErventions Via Distal vs Proximal aCcess

The objective of the study is to determine that a coronary angiography (CAG) or percutaneous coronary intervention (PCI) via a distal puncture of the radial artery (distal transradial acce...

Distal arteriovenous fistula formation after percutaneous coronary intervention: An old complication of a new access site.

Dorsal or distal transradial artery access has recently gained popularity due to several perceived benefits that include favorable ergonomics, the potential for rapid hemostasis and lower rates of vas...

Preventing spasm of the radial artery conduit during coronary artery bypass grafting: Nicardipine versus verapamil.

In vitro studies have shown a reduction in radial artery spasm with the use of calcium antagonists. The purpose of this study was to evaluate the efficacy of topical treatment of the radial artery con...

Analysis of subjective and objective screening techniques as predictors of safety for radial artery intervention.

There is no current accepted standard in safety evaluation for radial artery intervention. We sought to compare the accuracy of various subjective and objective screening techniques in predicting safe...

Radial Artery Dilatation to Improve Access and Lower complication rates during coronary angiography (RADIAL): A Randomized Controlled Trial.

To explore the use of prolonged occlusion flow mediated dilatation (PO-FMD) to dilate the radial artery prior to cannulation to increase cannulation success, reduce puncture attempts and reduce access...

Short-term outcomes of sequential radial artery grafting in patients with coronary artery disease.

To explore the short-term outcomes of patients with coronary artery disease (CAD) who underwent coronary artery bypass graft (CABG) with sequential radial artery graft. Clinical data of patients with...

Medical and Biotech [MESH] Definitions

The larger of the two terminal branches of the brachial artery, beginning about one centimeter distal to the bend of the elbow. Like the RADIAL ARTERY, its branches may be divided into three groups corresponding to their locations in the forearm, wrist, and hand.

The continuation of the axillary artery; it branches into the radial and ulnar arteries.

The direct continuation of the brachial trunk, originating at the bifurcation of the brachial artery opposite the neck of the radius. Its branches may be divided into three groups corresponding to the three regions in which the vessel is situated, the forearm, wrist, and hand.

A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.

Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
