There, local vascular surgeons replaced the temporary bypass with a permanent bypass and repaired the artery using a section of the patient's vein. "Our task was not only to save the organ, but also to ensure complete healing of the extensive defect. After several dressing changes, we implanted a fat flap in the skin from the patient's thigh. The flap took root," said Roman Kostiv, head of the hospital's trauma department. The boy faces a long recovery, but the most important thing has already been done - the doctors saved his hand.
