Abstract:
Objective To explore the clinical efficacy of 1251 stent implantation in treatment of malignant tracheal stenosis with the help of ventilation catheter under local anesthesia.Methods Totally 180 consecutive patients with malignant tracheal stenosis underwent 125I airway stent implantation were analyzed retrospectively.The anhelation grade,oxygen saturation and respiratory rate before and after operation were recorded and analyzed,125I stent situation,clinical symptoms and survival situation were followed up after operation.Results The success rate of 125I stent placement was 100％ (180/180),and the stent type was tubular stent in 132 cases,Y-shaped stent in 34 cases,and L-shaped stent in 14 cases.Dyspnea was significantly relived in all patients.Oxygen saturation and respiratory rate improved from (80.60±3.87)％ and (29.36± 3.20)times/min before operation to (94.31±3.40)％ and (19.29±2.19)times/min after operation (t=-30.52,35.09,both P＜0.01).Patients were followed up 3-13 mouth after operation,and stent restenosis were occurred in 6 patients.The lifetime was 49-401 days and the average lifetime was (182±94) days.The 60-day survival rate was 0.99 and the 180-day survival rate was 0.65.Conclusion 125I stent implantation in treatment of malignant tracheal stenosis with the help of ventilation catheter under local anesthesia is a safe and effective method.
