How interventional radiology is changing treatment for chronic pain and vascular conditions

For patients living with chronic pain or vascular disease, treatment has often involved a difficult trade-off. Long-term medication may help manage symptoms but does not address the underlying problem. Surgery, while more definitive, comes with its own risks and recovery.

Interventional radiology is increasingly being used as an alternative that sits between these two approaches. It offers a way to treat the source of the condition without the extent of intervention associated with open surgery. This has begun to change how a range of conditions from back pain and peripheral artery disease to uterine fibroids and liver tumours are managed.

Precision through imaging, not larger procedures

Interventional radiology relies on imaging guidance such as ultrasound, CT, and fluoroscopy to perform targeted procedures through very small entry points. Instead of operating directly on an organ, treatment is delivered with precision to a defined area.

A catheter can be guided through blood vessels to reach the site of disease. Ablation techniques such as radiofrequency or cryoablation allow abnormal tissue to be treated without opening the body. Embolisation procedures can reduce or block blood supply to tumours or vascular malformations.

What distinguishes this approach is not only the method, but the level of control. The intervention is guided in real time and adjusted based on the patient’s anatomy. Increasingly, imaging is also being used alongside clinical data to plan procedures more specifically, rather than relying on standardised pathways.

Where this approach is making a difference

The conditions that tend to benefit most from interventional radiology are those that are chronic, impact quality of life, and have traditionally been managed either conservatively or through more invasive procedures.

Peripheral artery disease is one example. Reduced blood flow to the limbs, which is common in older and diabetic populations, can now be addressed through angioplasty and stenting delivered via a catheter, without the need for open vascular surgery.

Chronic musculoskeletal and spine-related pain is another area where this shift is visible. Instead of broadly treating a region, image-guided nerve blocks, injections, and ablation procedures allow the treatment to focus on the specific structure responsible for the pain.

Impact on hospital care and patient recovery

The implications extend beyond clinical outcomes. Many of these procedures can be performed under local anaesthesia in a catheterisation laboratory rather than an operating theatre. In several cases, patients can return home the same day or within 24 hours.

This reduces hospital stay, lowers the cost per episode of care, and allows healthcare systems to treat more patients within existing infrastructure. For patients, the benefit is not only clinical but also practical, with less disruption to daily life.

The challenge of access

Despite these advantages, access remains uneven. Interventional radiology requires both advanced imaging systems and trained specialists, which are currently concentrated in larger urban centres.

While tele-radiology and digital reporting can support aspects of care, the procedures themselves require on-site expertise and infrastructure. Expanding access will depend on investment in equipment, training, and the development of capabilities beyond metro hospitals.

A shift in how care is delivered

As imaging improves and the range of treatable conditions expands, the role of the radiologist is also changing. It is no longer limited to diagnosis and reporting. In many cases, it now involves direct participation in treatment.

Across vascular disease, oncology, pain management, and women’s health, interventional radiology is becoming an integral part of how care is planned and delivered. For patients who previously had limited options, this approach is opening up a different way forward—one that is more targeted, and often less disruptive.
