Visualization research in the anatomical snuffbox region using gross anatomy,upper limb CT angiography and color Doppler ultrasound
Objective:To investigate the visualization of the anatomical structures in the snuffbox region using gross anatomy dissection,CT angiography(CTA)and color Doppler ultrasound based on the background of the distal radial artery access.Methods:Adult cadaver specimens for anatomical teaching were selected to dissect the anatomical structures of the snuffbox region and observe the corresponding gross anatomical structures through transradial intervention.Then,adult upper limb CTA images and adult snuffbox region ultrasound images were taken to reproduce the gross anatomical observations on CTA and ultrasound.The differences in the radial artery of the snuffbox region using these three different methods were compared and the diameter of the radial artery in the snuffbox region was measured.Results:Gross anatomy provided a clear view of the structures of each part,but it was difficult to express the relations between the bones and superficial structures.Upper limb CTA provided a good visualization of the bones,radial artery and some veins,but the muscles and tendons were barely recognizable,and the radial nerve cannot be reproduced.Color Doppler ultrasound of the snuffbox region provided a good visualization of the diameter of arterial and venous vessels,and the radial nerve could be recognized with difficulty.The diameter of the distal radial artery was measured by the three methods and the average result was(2.45±0.56)mm,while the diameter was(2.62±0.55)mm using gross observation,(2.48±0.62)mm using CTA,and(2.36±0.20)mm using color Doppler ultrasound.There was no statistical difference among the pairwise comparisons.Conclusions:Combining upper limb CTA with color Doppler ultrasound can generally reproduce the anatomical structures in the snuffbox region,but the visualization of some structures is poor,such as the radial nerve and adipose tissue within the superficial fascia.
