Angioma diathermy is a medical procedure that uses high-frequency electrical currents to generate heat inside the blood vessels that make up the angioma, resulting in its destruction. Angiomas are abnormal vascular formations that develop in the skin and can appear in a variety of forms, including plane angiomas, cavernous angiomas and tuberous angiomas.

Diathermy is often used to treat small cutaneous angiomas, particularly those that are superficial and accessible. During the diathermy procedure, an electrode is applied to the skin close to the angioma, and a high-frequency electric current is applied. The heat generated by this electric current targets the angioma's abnormal blood vessels, causing them to coagulate and destroy.

Here are the typical steps in angioma diathermy:

• Preparation: Prior to the procedure, the area to be treated is cleaned and disinfected.
• Local anesthesia: Local anesthesia can be administered to numb the treatment area and minimize discomfort during the procedure.
• Application of diathermy: The electrode is applied to the skin near the angioma, and a high-frequency electric current is applied for a short period of time to target the abnormal blood vessels.
• Note: After the procedure, the treated area may experience temporary redness, swelling or crusting. These side effects generally disappear within a few days to a few weeks.
• Post-operative care: Specific post-operative care instructions are usually provided to the patient to promote healing and reduce the risk of complications. This may include applying healing ointments and protecting the treated area from trauma.
