**3.5 Microvascular anastomosis and breast reconstruction**

The recipient artery and vein were dissected and reserved, with the distal ends being ligated and the proximal ends being clamped. The blood vessels within the chest wall were trimmed. The flap was moved to the breast defect site and temporarily fixed, and the veins and arteries below the abdominal wall were trimmed. Microscopic vascular anastomosis was performed using 9-0 or 10-0 prolene suture thread. The patency of the anastomosis was checked. After the flap blood supply was established, the shape of the breast was formed.
