Abstract: Objective To summarize the experience of cardiopulmonary bypass(CPB)in the surgical treatment of severetracheal stenosis.
Methods Three patients with severe tracheal stenosis were retrospectively analyzed from January 2009 to May 2014.After establishing normothermic femoral artery-vein extracorporeal circulation,tracheal tumor resection and end-to-end anastomosis,resection of giant goiter,and benign tracheal stenosis resection and end-to-end anastomosis were employed under general anesthesia,respectively.
Results With the assistance of CPB,the operation was successfully and safely finished in 3 patients.The CPB time was 30～120 minutes.The bleeding was 100～1000ml during the operation and the patients recovered uneventfully after the operation.There was no recurrence in 3～9 years follow-up.
Conclusion Surgery is an important method for the treatment of tracheal stenosis.CPB is an effective and feasible method for the patients with severe tracheal stenosis to get through anesthesia,intubation and surgery,while related complications should be taken to avoid.
