Aim: Postoperative ischemic wound healing in a patient after breast cancer surgery. A 63-year old female patient was operated on for carcinoma of the right breast with an axillary lymph node tumor. At the end of November 2021, the patient underwent ablation of the right breast, biopsy of the protective lymph node and immediate reconstruction of the right breast with the insertion of an expander. Method: After the operation, marginal ischemia of the skin occurred next to the surgical scar. The patient was referred to a wound care specialist - an enterostomal therapist. A wound care plan was created, namely stimulation of tissue microcirculation with an oxygen-enriched oil base and application of a modern dressing. She was also referred to the clinic for outpatient clinical nutrition, where clinical nutrition experts advised her to increase her protein intake. The patient was a passionate smoker. Results / Discussion: The patient regularly came to the outpatient clinic for wound dressing. She stopped smoking and ate a balanced diet with a protein supplement. The wound was healing fast. With the patient's consent, we took a photo of the wound to monitor her healing. After 6 weeks, the wound had completely healed. Conclusion: Smoking is a key risk factor for poorer blood circulation to tissues and consequently poorer wound healing, with a higher risk of infection and scarring. The patient is advised to stop smoking.
