Summary
Patients undergoing fluoroscopically guided vascular procedures may develop radiation-induced skin injuries. Awareness and preventative measures are crucial to mitigate risks of radiodermatitis following interventional procedures.
Area of Science:
- Interventional Radiology
- Radiation Oncology
- Dermatology
Background:
- Fluoroscopically guided interventional procedures carry a risk of significant ionizing radiation exposure to patients.
- High cumulative radiation doses are associated with prolonged or repeated endovascular procedures.
Observation:
- Five male patients developed radiodermatitis after vascular catheterization, including cardiac and renal artery interventions.
- Clinical presentations ranged from acute to chronic radiodermatitis, with some cases involving extensive ulceration requiring surgical consideration.
- Onset of skin lesions varied from weeks to years post-procedure.
Findings:
- Coronary angiography and percutaneous transluminal angioplasty deliver high radiation doses, increasing the risk of radiodermatitis.
- Approximately 20 cases of radiodermatitis post-coronary angioplasty have been documented since 1996.
- Radiodermatitis is also reported following other vascular interventions like radiofrequency ablation and neuroradiologic procedures.
Implications:
- Medical professionals must recognize radiodermatitis as a potential side effect of interventional procedures.
- Implementing strategies to minimize radiation skin injury is essential for patient safety in interventional radiology.
- Further research into dose reduction techniques and patient monitoring is warranted.
