Hypothesis
Can sublingual glyceryl trinitrate (GTN) improve radial artery access for prostatic artery embolization?
Conclusion
Sublingual GTN significantly increases radial artery diameter and improves symptoms after prostatic artery embolization.
Supporting Evidence
- Sublingual GTN resulted in a statistically significant increase in radial artery diameter.
- 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%).
Takeaway
Doctors found that a special medicine made the artery bigger, which helped them do a procedure better and made patients feel better afterward.
Methodology
This was a single-centre prospective observational study evaluating radial access in 62 prostatic artery embolization procedures.
Limitations
The study had a small sample size and lacked long-term follow-up data, particularly regarding complications like radial artery occlusion.
