case_images: Preoperative cervical CT and fiberoptic bronchoscopy. (A) CT shows thyroid carcinoma invading trachea (arrow). (B) Fiberoptic bronchoscopy shows a protuberant tumor on the right anterior wall of the trachea, and the tracheal lumen is obviously narrow (arrow).

case_images: Figure 1A ). Fiberoptic bronchoscopy showed a protuberant tumor on the right anterior wall of the trachea, which was about 3 cm away from the glottis; the tracheal lumen was obviously narrow; no obvious abnormality was found in the remaining bilateral bronchus ( Figure 1B ).
case_images: Intraoperative photographs. (A) Thyroid cancer invades the trachea (arrow). (B) The second and third tracheal rings and tumors are annularly resected with tracheal intubation ventilation condition. (C) The trachea end-to-end sleeve anastomosis is ongoing with ECMO ventilation. (D) The anastomosis is completed, with left recurrent laryngeal nerve with nerve detection and protection (arrow). (E) Right recurrent laryngeal nerve with nerve detection and protection (arrow). ECMO, extracorporeal membrane oxygenation.

case_images: The upper and lower parathyroid glands were retained, the thyroid tissue was cut off at the isthmus of the thyroid, and the right and left thyroid glands were successfully removed, avoiding the invaded trachea ( Figure 2A ). The second and third tracheal rings and tumors were annularly resected 0.5 cm away from the upper and lower ends of the tracheal tumor ( Figure 2B ). The trachea end-to-end sleeve anastomosis of the trachea was completed without tension ( Figures 2C-E ).
case_images: Postoperative neck-chest CT. (A) Transverse image shows the right anterior wall of the cervical trachea returned to normal. (B) coronal image shows the right anterior wall of the cervical trachea returned to normal.

case_images: Postoperative neck-chest CT imaging of the respiratory tract showed that the right anterior wall of the cervical trachea returned to normal ( Figures 3A, B ).
