X Feng, male, 39 years old, Nanjing, engineer. History of progressive dyspnea for 2 years. x-ray and CT showed tumor in the upper trachea. postoperative pathology: adenoid cystic carcinoma invading the thyroid gland. Pre-operative diagnosis of tracheal tumor, length >7 cm. after surgical resection, a stage 1 anastomosis was definitely not possible. He has been seen in several tertiary hospitals in Luching, and no one has been seen. Considering the necessity of replacing the trachea with an artificial trachea, he finally came to our hospital for consultation. The surgery was very difficult. Because the tumor was huge. The picture below shows that the tumor was garden-shaped and infiltrated irregularly into the surrounding area. The length of the resected specimen reached 8 cm. 3 weeks before surgery, a phase I memory alloy mesh neck subcutaneous embedding surgery had been done, therefore, the second surgery was performed to remove the tumor and prepare Zhao’s artificial trachea at the same time. After tumor removal, a missing area of >8 cm was left between the two severed ends of the trachea, and direct anastomosis was not possible, and could only be replaced by artificial air and. The memory alloy mesh was rolled up together with the skin subcutaneous tissue to form a sandwich type artificial trachea, with the inner layer of skin, the middle of memory alloy mesh, and the outer layer of subcutaneous tissue and broad neck muscle. The artificial trachea is 5.5 cm long and is underlain by a muscular vascular tip formed by the sternocleidomastoid muscle, which ensures the blood supply to the artificial trachea and the survival of the skin on the inner surface. The artificial trachea was placed between the two broken ends of the trachea and anastomosed with the upper and lower ends of the trachea respectively. After surgery, the trachea was very patent and the patient was able to eat normally and walk in bed on the 2nd day. On the 9th postoperative day, a small complication occurred, namely, a small fissure at the suture of the opposite end of the artificial trachea, as shown in the CT below, and a small amount of gas escaped, forming a subcutaneous emphysema. It healed after venting by incision of the skin. The patient was discharged from the hospital and resumed normal life. He died a year and a half later due to extensive metastasis of the tumor. In any case, the patient was successfully treated from the brink of death with high respiratory distress and almost suffocation, prolonged life expectancy and normal survival for a precious period of life. It also shows that Zhao’s artificial trachea can achieve biological healing with the human trachea, fuse into one and become an organic part of one’s own trachea. It is the only natural trachea that comes closest to God’s creation of man so far. It will bring hope to more patients with severe tracheal tumors or tracheal stenosis!
