Background:
This is a single-centre prospective observational study examining radial access in 62 Prostatic Artery Embolisation (PAE) procedures. Evaluation of left radial artery diameter using high frequency ultrasound before and after administration of sublingual glycerl trinitrate (GTN). Pre-procedure questionnaires calculating symptom severity score compared with post-procedure.
Results:
Sublingual GTN resulted in a statistically significant increase in radial artery diameter (p < .00001). There was a statistically significant reduction in both average International Prostate Symptom Score (IPSS) and Quality of Life (QoL) from pre-procedure to post-PAE. The radial sheath was successfully inserted in 100% of cases. Crossover rate to femoral access was low (4%). Radial artery access had a low complication rate (2%). Radial artery variant anatomy was reasonably common (7%).
Conclusions:
Sublingual GTN significantly increase radial artery diameter. PAE from radial access is associated with a symptomatic improvement at 2-month follow-up.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
