Randomized Comparison of Radiation Exposure in Coronary Angiography Between Right Conventional and Left Distal Radial Artery Approach

Randomized Comparison of Radiation Exposure in Coronary Angiography Between Right Conventional and Left Distal Radial Artery Approach: The DOSE Trial

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.
