CRPS Embolization

Context and indications

Complex regional pain syndrome (CRPS), formerly known as algodystrophy, is a chronic painful condition that typically occurs after trauma or surgery. It is characterized by intense pain, swelling, skin changes and functional limitation. Embolization is offered for CRPS refractory to conventional medical treatments.

Benefits

Significant reduction in pain and inflammation, minimally invasive treatment targeting pathological neovascularization that sustains the pain cycle, alternative to repeated nerve blocks.

Procedure

Under local anesthesia, a micro-catheter is inserted through the radial or femoral artery and guided to the arteries of the affected area. Microparticles are injected to reduce pathological inflammatory neovascularization. The procedure takes 1 to 2 hours.

Risks

Transient pain at the treatment site, puncture site hematoma, skin ischemia (exceptional), symptom recurrence.

Follow-up

Same-day discharge. Improvement is progressive over 2 to 6 weeks. Functional rehabilitation program to continue. Follow-up consultation at 1-3 months.

Practical information

The procedure is performed under local anesthesia on an outpatient basis (same-day discharge).
