Abstract

Objective To explore the value of examination of fore arm artery using Doppler ultrasound before transradial coronary intervention (TRI).

Methods Consecutive patients undergoing elective TRI were screened. Including criteriors were as follows: positive Allen's test result of right radial artery (RRA). The primary endpoints included the procedural success rate and incidence of vascular related complications. The secondary endpoints were: the average diameter of fore arm diameter and anatomic variations of approach.

Results A total of 1863 patients were eligible and assigned to ultrasound group (931 cases) and convention group without ultrasound examination (932 cases). The baseline clinic characteristics in two groups were comparable. 181 cases of anatomic variation in RRA approach were detected before procedure. Among these, approach in 13 cases changed to other routes from RRA. The procedural success rate in ultrasound group and convention group was similar (98.0% vs 97.2%, p=0.292). The incidence of vascular complications in ultrasound group was significantly lower than convention group (8.7% vs 11.6%, p=0.039). Regarding artery perforation and radial artery occlusion, the incidences of those in ultrasound group occurred less frequently (p=0.025 and 0.028, respectively).

Conclusions Examination of fore arm artery using Doppler ultrasound could not only detect anatomic variations and reduce vascular complication effectively, but also be helpful to selective suitable approach and instruments.

  • Transradial approach
  • coronary angioplasty
  • procedural success
  • vascular complication
