About

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

Full description

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.

100 participants in 2 patient groups, including a placebo group

Right conventional radial approach
Placebo Comparator group
Description:
After local anesthesia on right wrist area with lidocaine hydrochloride using a 26 gauge needle, the puncture is performed using a 20 gauge needle with the through-and-through puncture technique or a 21 gauge open needle with anterior wall puncture technique. After the successful puncture, 0.025-inch straight wire or 0.018-inch hair wire are inserted, followed by insertion of the 5Fr. radial sheath (Prelude® Radial; Merit medical, UT, USA or Radifocus® Introducer II or Glidesheath Slender®; Terumo Corporation, Tokyo, Japan).
Treatment:
Procedure: artery puncture and coronary angiography
Left distal radial approach
Active Comparator group
Description:
After local anesthesia on left anatomical snuffbox area with lidocaine hydrochloride using a 26 gauge needle, the puncture is performed using a 20 gauge needle with the through-and-through puncture technique or a 21 gauge open needle with anterior wall puncture technique. After the successful puncture, 0.025-inch straight wire or 0.018-inch hair wire are inserted, followed by insertion of the 5Fr. radial sheath (Prelude® Radial; Merit medical, UT, USA or Radifocus® Introducer II or Glidesheath Slender®; Terumo Corporation, Tokyo, Japan).
