Overview

Randomized comparison of radiation exposure in coronary angiography between right conventional and left distal radial artery approach

The left snuffbox approach is expected to be easier to perform because of less severe tortuosity of the clavicle artery. However, clinical validation of the snuffbox approach was not completed compared with the conventional radial approach. Especially, there is no clinical data on the comparison of the radiation dose in both approaches. To date, there have been some studies on the radiation dose between the left and right radial artery and femoral artery puncture site, but no studies have been conducted on the left snuffbox approach. The purpose of this study was to compare the radiation doses of the two interventional radiologists by randomly assigning coronary angiography to the left snuffbox approach and right conventional radial approach.

Interventions

artery puncture and coronary angiographyPROCEDURE

We will perform coronary angiography through a Judkins 5 French diagnostic catheter and will take a basic view. At the end of the examination, the radial sheath is removed and the right conventional radial approach is performed for about 4 hours and the left snuffbox approach for about 2 hours using the compressive bandage method. The hemostatic device will use ez ClotRadial® (SOYEON medical Co., Ltd., Wonju, Korea).
