Observational Study of Hand Function After Distal Transradial Access for Angiography

2019-01-08 10:07:36 | BioPortfolio

Summary

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 procedure from the back of the wrist in as the radial artery courses through the anatomical snuffbox (distal radial access). The aim of this study is to determine the prevalence of hand dysfunction following coronary angiography via the distal radial artery.

Description

In this multi centre observational registry, we will recruit patients undergoing planned invasive coronary angiography. Inclusion criteria include:

1. Age ≥ 18 years.

2. The distal radial artery must be palpable and non-occlusive flow must be confirmed by Doppler ultrasound.

3. Patient should be able to comply with the protocol.

4. Provide written informed consent before study participation.

The primary endpoint is the overall prevalence of hand dysfunction defined as any significant reduction from baseline score in any of the following five domains:

DASH score Levine Katz score VAS score Sensory function Pinch grip strength.

Specifically hand function will be assessed at 4 time points using simple tests of hand strength, sensation and ultrasound to assess the arterial latency.

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.

Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.

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.
