Thoracic radionecrosis following repeated cardiac catheterization

Area of Science:

• Cardiology
• Dermatology
• Oncology

Background:

• Radiodermatitis is a common side effect of radiotherapy, usually manifesting 2-5 years post-treatment.
• Coronary artery interventions, like stenting, are not typically associated with radiodermatitis.
• This case highlights an unusual presentation of radiodermatitis following cardiac procedures.

Observation:

• A patient developed painful swelling and skin lesions months after coronary dilatation and stenting.
• Histological examination confirmed radiodermatitis.
• Magnetic resonance imaging revealed subcutaneous tissue changes extending to the ribs.

Findings:

• The patient experienced early-onset radiodermatitis post-cardiac intervention.
• Surgical management involved radical debridement and removal of a necrotic rib.
• Reconstruction was achieved using a latissimus dorsi transposition flap.

Implications:

• This case expands the known timeline and potential triggers for radiodermatitis.
• It underscores the importance of considering atypical causes of skin complications after interventional procedures.
• Further research may be needed to understand the mechanisms linking cardiac interventions to radiodermatitis.
