Safety of interventional of high pressure balloon expansion catheter applicated in benign and malignant airway stenosis lesions treatment

Abstract

Objective To explore the security and its influencing factors on benign airway stenosis treated with interventional of high pressure balloon expansion catheter. Methods Clinial data of 39 cases of inpatients suffered from benign airway stenosis were chosen.17 cases were male, and 22 cases were female.The ages of them ranged from 15 to 83 years old.According to the clinical symptoms, HRCT 3D reconstruction, and the results of bronchoscope, all patients were treated with balloon expansion catheter at different criterions.The balloon catheter with size that slightly smaller than the targeted normal bronchial tube was chosen, expansion for average 1-4 times, single balloon expansion time ranged from 0.5 to 4 min, the pressures were kept at 3-6 atmosphere, and the highest pressure did not exceed 8 atmospheric pressure.The efficacy and complications were retrospectively analyzed. Results 19 cases were completely effective, 14 cases were basically effective, 6 cases were completely ineffective, and the total effective rate was 84.6%(33/39), the incidence of complications was 35.8%(14/39), moreover, no deaths occurred. Conclusion High pressure balloon catheter expansion is one of commonly used technology in breathing interventional treatment; it has the characteristics of easy operation, and immediate curative effect, and so on.But if the improper operation, incorrect selection of the case, or inaccurate evaluation of the stenosis during operation, serious complications and unnecessary iatrogenic injury can be occurred.Therefore, it is worthy of attention and further summarizing by breathing interventional physicians.
