Radiodermatitis after spinal arteriovenous fistula embolisation

Area of Science:

• Interventional Radiology
• Dermatology
• Medical Imaging

Background:

• Endovascular embolisation of spinal arteriovenous malformations is an increasingly common procedure.
• Fluoroscopic guidance is essential for these interventions, leading to potential radiation exposure for patients.
• Radiation-induced skin injuries, or radiodermatitis, are a known complication of prolonged fluoroscopy.

Observation:

• A patient developed acute radiation dermatitis on their back and left arm four weeks post-procedure.
• The dermatitis presented with vesiculation and erosions, followed by re-epithelialisation.
• Skin changes resolved within one month, leaving hyperpigmented patches.

Findings:

• This case details radiation dermatitis following spinal arteriovenous malformation embolisation.
• The observed skin reaction and subsequent resolution pattern are described.
• This represents one of the few reported cases of radiodermatitis after this specific intervention.

Implications:

• Highlights the risk of radiation dermatitis even in complex spinal interventions.
• Emphasizes the need for careful radiation dose monitoring and management in interventional radiology.
• Suggests further investigation into the incidence and prevention of radiodermatitis in spinal procedures is warranted.
