镍钛合金支架置入治疗良恶性气道狭窄术后并发症差异的分析

目的探讨镍钛合金支架置入治疗良恶性气道狭窄的近、远期并发症的差异和原因。方法回顾性分析60例进行过镍钛合金支架置入术患者的术后近、远期并发症的差异。结果恶性气道狭窄患者近期咯血发生率高于良性气道狭窄患者,但其近期气道肉芽组织形成率低于良性患者;在远期,恶性气道狭窄患者的肺部感染率和肉芽组织的形成率都高于良性患者。结论镍钛合金支架置入是治疗良恶性气道狭窄的有效方法,术后的并发症因不同的病因有较大的差别。

Clinical analysis of complications of nitinol stent implantation for patients with benign or malignant tracheobronchial stenosis

Objective To discuss the differences and causes of earlier and later complications of nitinol stent implantation for patients with benign or malignant tracheobronchial stenosis.Methods Sixty patients with tracheobronchial stenosis analyzed retrospectively the incidence of earlier and later complications of nitinol stent implantation.Results In the earlier period,the incidence rate of postoperative hemoptysis of patients with malignant tracheobronchial stenosis was higher than that of benign patients, but its incidence of granulation tissue formation in airway was less than that of benign ones.In the later period, the incidence of pulmonary infection and granulation tissue formation of patients with malignant tracheobronchial stenosis were higher than those of benign ones. Conclusions It is more effective modus with nitinol stent implantation for patients with airway stenosis, but there were great differences of postoperative complications between malignant and benign tracheobronchial stenosis.
