Direct image-guided treatment of chronic pain · No open surgery · Millimetre precision

Interventional radiology for chronic pain

Interventional radiology offers a unique set of tools for treating chronic pain resistant to medical management. Our techniques act directly on the anatomical source of pain — a vessel, nerve, tumour, or joint — under imaging guidance, with millimetre precision and without open surgery.

Interventional algology encompasses all interventional radiology techniques applied to pain treatment. It is integrated within a multidisciplinary programme including pain physicians, rheumatologists, neurologists and oncologists.

Our techniques

🧠 Image-guided neurolysis

Chemical (alcohol, phenol) or thermal destruction of pathological nerves. Indicated for cancer pain (coeliac plexus, superior hypogastric plexus block), post-amputation neuromas, and refractory neuropathic pain.

⚡ Electrochemotherapy (ECT)

Treatment of painful spinal metastases causing epidural cord compression (epiduritis) and subcutaneous or cutaneous metastases. Combines electroporation and bleomycin. Pain reduction in 70–80% of cases. → Spinal ECT page

🦴 Vertebroplasty & cementoplasty

Injection of bone cement into painful vertebral fractures (osteoporotic or tumour-related) or metastatic bone lesions. Immediate pain relief in most cases. → Vertebroplasty page

🦵 Genicular artery embolization — Knee osteoarthritis

Selective embolization of the hypervascular synovial membrane responsible for inflammatory knee pain. Outpatient, local anaesthesia. → Knee page

💪 Tendinopathy embolization

Selective embolization of pathological neovascularisation in chronic refractory tendinopathies (lateral epicondylitis — tennis elbow; greater trochanteric pain; plantar fasciitis). → Tennis elbow page

🦶 Morton's neuroma

Ultrasound-guided alcohol injection or embolization for interdigital neuromas causing forefoot pain. → Morton's neuroma page

Multidisciplinary pain management: All chronic pain cases are reviewed jointly with our pain medicine colleagues. We accept referrals from pain clinics, rheumatologists, orthopaedic surgeons and oncologists. Please send referrals to ri.cch@aphp.fr.

Covered by French health insurance (Assurance Maladie). No extra fees at Cochin Hospital AP-HP.

Frequently asked questions

A range of conditions including knee osteoarthritis (genicular artery embolization and nerve radiofrequency), tennis elbow, Morton's neuroma, vertebral fractures (vertebroplasty), and cancer-related pain via cryoneurolysis of various nerve targets.
In many cases, yes — they are considered after conservative treatment (physiotherapy, injections) has failed and before or instead of surgery, since they typically preserve the option of surgery later if needed.
Yes. At Cochin AP-HP (a French public hospital), procedures are covered by national health insurance with no out-of-pocket fees. Contact ri.cch@aphp.fr or +33 1 58 41 46 12.
