Our aim was to establish the long term incidence of radial artery occlusion and investigate its predictors.
Radial artery occlusion (RAO) is an infrequent complication of transradial coronary procedures (TRA). To our knowledge, there are no studies reporting the incidence and predictors of RAO in the late term following TRA.
This was a single center prospective study. A total of 409 consecutive patients undergoing their first TRA were recruited. Clinical and procedural data were all recorded. Doppler ultrasound examination was performed at the time of 6-15 months following the TRA.
RAO was detected in 67 patients and 342 patients maintained radial artery patency (RAP). The overall RAO incidence was 16.4% at late term. Patients with RAO were younger than the patients with RAP (55.9±9.7 years versus 59.1±9.4 years, p=0,014). The incidence of RAO in hypertensive patients was 9.8%, lower (p<0.001) than the observed incidence (23.0%) in non-hypertensive patients. RAO group has higher rate (28%, p=0.027) of post-procedural access site pain. Regression analysis revealed that hypertension was negative while post-procedural access site pain was positive independent predictors for RAO. In addition the relative risk for RAO also increased significantly (p<0.001) when the ratio of sheath/artery diameter (S/A) was >1.
The present study reveals that the long term incidence of RAO is 16.4%. Hypertension, post-procedural access site pain and S/A ratio >1 are independent predictors of the long term incidence of RAO.
