Comparison in application of catheterization through distal transradial approach and conventional transradial approach in one-stop coronary and cerebral angiography
Objective To compare and observe the application effects of catheterization through distal transradial approach(dTRA)and conventional transradial approach(TRA)in one-stop coronary and cerebral angiography.Methods Forty-nine participants who underwent selective one-stop coronary and cerebral angiography were randomly di-vided into the dTRA group(n=24)and TRA group(n=25).Subjects in the dTRA group underwent"one-stop"coronary and cerebral angiography via catheterization through dTRA;while those in the TRA group received"one-stop"coronary and cerebral angiography via catheterization through TRA.Further observation and comparison were performed on the suc-cess rate of catheterization,duration of catheterization,surgical time,X-ray exposure duration,cumulative intraoperative radiation dose,contrast agent dosage,duration of compression hemostasis,postoperative blood oxygen saturation on the in-dex finger,postoperative length of stay in the hospital,VAS scores on postoperative day 1 and day 3,the degree of patient satisfaction and other surgical related data between the two groups as well as the occurrence of postoperative complications such as vasovagal reflex,bleeding at the puncture site,tension hematoma in the right hand and forearm,radial nerve inju-ry,radial artery occlusion,radial artery spasm,and skin ulceration,etc.Results The duration of catheterization and the degree of patient satisfaction in the dTRA group were higher than those in the TRA group,while VAS scores on postop-erative day 1 and day 3,and duration of compression hemostasis were lower than those in the TRA group(all P<0.05).Furthermore,subjects in both groups did not experience any complications such as vasovagal reflex,bleeding at the punc-ture site,tension hematoma in the right hand and forearm,radial nerve injury,radial artery occlusion,radial artery spasm,skin ulceration,etc.Conclusions The"one-stop"coronary and cerebral angiography via catheterization through dTRA can alleviate postoperative pain,shorten the duration of compression hemostasis,and improve the degree of patient satisfaction in comparison with the catheterization through TRA.It can be accepted as one of the routine approaches for"one-stop"coronary and cerebral angiography.
