The preferred entry for angioplasty and coronary interventions was the femoral artery in the groin for decades. These days, more and more cardiologists are reaching for the wrist. This move to transradial access is not a trend. Still, it is supported by growing clinical evidence of safety, recovery and patient comfort.
The old way: Femoral access
The femoral route has long been the preferred approach because the artery is large and easily accessible, allowing for larger catheters and devices for complex procedures. But there is a price to pay for this convenience. Penetrations to the groin are more likely to cause major bleeding, haematoma formation, pseudoaneurysms and the rare but serious retroperitoneal bleed. Usually, patients need to stay in bed for several hours of strict rest afterwards to allow the puncture site to seal. This can mean a longer hospital stay and a less comfortable recovery.
Pain points for patients
Femoral access for patients may include:
- Staying flat on your back for 4 to 6 hours after the procedure, prolonged immobility.
- Groin pain and bruising that can last for days
- Bleeding concerns in the elderly and patients on anticoagulants
These are real quality of life issues, not just clinical statistics. They are a big reason for the gains that have been seen with radial access.”
Reasons for increase in preference of Wrist Method
The radial artery is smaller, more superficial, and much easier to compress after the procedure. This anatomical advantage translates into important clinical advantages: lower rates of bleeding at the access site, fewer vascular complications and, in several large studies, lower in-hospital mortality compared with femoral access, particularly in patients suffering heart attacks.
Radial is where the recovery really shines. You can compress the wrist right away with a simple band. Patients can sit up, walk and even eat a couple of hours after surgery, instead of lying flat for half a day. Patients also report less pain, are more satisfied with the total experience, and hospital stays tend to be shorter.
What comes next?
However, radial access comes with its challenges. Operators take longer to learn it, and navigating complex lesions or using larger devices is harder because of the smaller artery. Radial access fails in a small percentage of cases, and the procedure has to crossover to a femoral approach mid-procedure. In the research community, there is also ongoing debate as to whether radial provides a true mortality benefit or “just” a comfort/bleeding risk benefit. Still, most cardiology bodies now view radial as the preferred default if possible.
For most patients having angioplasty today, the wrist is the preferred option, not because the femoral route is now outmoded, but because radial access offers a better combination of safety, comfort and faster recovery. Femoral access remains an important alternative in complex cases or if radial access is not technically feasible. The trend toward “radial-first” cardiology will likely continue to grow as techniques and operator training improve, focusing on patient comfort and faster recovery in interventional care.
