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 125Iodine 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, 125Iodine seed stent may present some fatal complications. Therefore, the long-term efficacy of 125Iodine seed stent remains to be studied.
