Interventional therapy of late onset tracheal stenosis after implantation of 125Iodine seed esophageal stent

This study reported a case of late-staged esophageal carcinoma, complicated by severe dyspha late onset tracheal stenosis after treating with  125 Iodine seed stent implantation. The patient had progressive stenosis of the lower segment (left main trachea) at 6, 26, and 47 days postoperatively. The cause of stenosis might be related to direct press by stent, tumor proliferation, the aortic arch with violate pulsate and the complications caused by other therapies. Due to its short clinical utilization,  125 Iodine seed stent may present some fatal complications. Therefore, the long-term efficacy of  125 Iodine seed stent remains to be studied.  Keyword: 125 Iodine seed, esophagus stent, late onset, tracheal stenosis, complication
