Hello,
Your father is suffering from rashes and itching in the under belly after
angioplasty. Before angioplasty always tell your treating doctor history of any allergy you have,
anaphylaxis, allergy to iodine dye, allergy to any medicine or asthma, etc. so that he may take adequate precautions. Common side effect is an
allergic reaction to the contrast dye. This reaction may manifest itself in the form of itching or rash if mild.
Take care of his hygiene, he should wear soft cotton clothes and should not touch or scratch the area of the affected skin. He can apply calamine lotion or
Soframycin ointment for relieve or he can also apply a thin layer of
Hydrocortisone ointment on the area affected. Cold compress is also helpful. In case he develops breathing problems, vomiting, low blood pressure, and heartbeat disorders or numbness may also be felt in the front of the thighs and legs, you must inform to your treating doctor. Your father may need urgent medical support / aid.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
