The procedure has been available at UHL since the opening of the hospital\u2019s new \u20ac2m catheterisation laboratories in 2024. RAD involves passing a catheter through the circulatory system to access the renal arteries and using radio-frequency waves or ultrasound to target the excessive nerve activity around the renal arteries that can contribute to high blood pressure.<\/p>\n<p>advertisement<a class=\"gofollow\" data-track=\"MTA4LDEwLDYw\" href=\"https:\/\/limetreebelltable.ie\/upcoming-ifibelltable-screenings\/\" target=\"_blank&quot;\" rel=\"nofollow noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/04\/1777544600_155_IFI.jpg\" height=\"300\" width=\"300\"\/><\/a>advertisement<br \/>advertisement<a class=\"gofollow\" data-track=\"MTEyLDEwLDYw\" href=\"https:\/\/www.thesavoycollection.com\/home\/gift-vouchers\/\" target=\"_blank&quot;\" rel=\"nofollow noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/04\/Savoy_2x1_900_900.png\" height=\"300\" width=\"300\"\/><\/a>advertisement<br \/>advertisement<a class=\"gofollow\" data-track=\"MTE1LDEwLDYw\" href=\"https:\/\/www.griffith.ie\/locations\/limerick\" target=\"_blank&quot;\" rel=\"nofollow noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2025\/10\/Advert-ILL.jpg\" height=\"300\" width=\"300\"\/><\/a>advertisement<br \/>advertisement<a class=\"gofollow\" data-track=\"MTA5LDEwLDYw\" href=\"https:\/\/limericktutorial.ie\/\" target=\"_blank&quot;\" rel=\"nofollow noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2025\/11\/MPU-Tutorial-College-.png\" height=\"300\" width=\"300\"\/><\/a>advertisement<\/p>\n<p>Even when accessing the arterial system via the groin, RAD is regarded as minimally invasive. The transradial procedure, completed by a multidisciplinary cardiology team led by Drs Arnous and O\u2019Connor in April 2026, is an even less invasive option for people struggling to contain hypertension, where the arteries are accessed through the wrist. In a further development for patient safety, the Limerick team also became the first in the world to deliver this procedure using a tiny 5 French catheter. The French scale is used internationally to measure the diameter of catheters used in healthcare.<\/p>\n<p>For patients, the benefits of RAD are significant:<\/p>\n<p>Reduced reliance on daily medication:\u00a0The procedure may help patients who do not respond well to multiple blood pressure drugs.<br \/>Lower risk of heart attack and stroke:\u00a0Better blood pressure control can significantly reduce the risk of serious cardiovascular events.<br \/>Preserves normal kidney function:\u00a0The treatment targets nerve activity without harming the kidneys.<\/p>\n<p>The Limerick team\u2019s wrist-based approach offers several additional advantages, as Dr Arnous explained:<\/p>\n<p>\u201cRenal denervation can be performed via either the radial artery in the wrist or the femoral artery in the groin, but radial access offers several practical advantages that are increasingly appealing to both patients and clinicians. Entering through the wrist is generally more comfortable, less invasive and allows patients to sit up and walk almost immediately after the procedure, avoiding the prolonged bed rest often required with femoral access. It also carries a lower risk of significant bleeding or vascular complications,\u201d he said.<\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"740\" height=\"341\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/05\/Cormac-Samer-l-3.jpg\" alt=\"The procedure, led by Drs Arnous and O\u2019Connor in April 2026, is an even less invasive option for people struggling to contain hypertension\" class=\"wp-image-395792\" style=\"aspect-ratio:2.169593389050615;width:534px;height:auto\"  \/>The procedure, led by Drs Arnous and O\u2019Connor in April 2026, is an even less invasive option for people struggling to contain hypertension<\/p>\n<p>Dr O\u2019Connor added: \u201cHigh blood pressure is one of the leading causes of heart disease and stroke worldwide, and many patients struggle to control it despite medication.
