镍钛记忆合金气管支架置入治疗良恶性气道狭窄并发症分析

摘要

目的：：分析镍钛记忆合金气管支架置入治疗良恶性气道狭窄的常见并发症发生情况。方法：对84例良恶性气道狭窄患者实施镍钛记忆合金气管支架置入治疗，所有患者均住院并接受气道内金属支架置入治疗，分析支架置入术后的近期、远期并发症情况。结果：术后近期随访统计，恶性气道狭窄组的咯血发生率高于良性气道狭窄组(P0.05)；恶性气道狭窄组的肉芽组织形成率低于良性气道狭窄组(P0. 05). The formation rate of granulation tissue in malignant airway stenosis group was obviously lower than that in benign airway stenosis group(P <0. 01). The postoperative long-term following-up results showed that the incidence of pulmonary infection in malignant airway stenosis group was higher than that in benign airway stenosis group(P<0. 05). The formation rate of granulation tissue in malignant airway stenosis group was significantly higher than that in benign airway stenosis group ( P <0. 05). Conclusions:The treatment effect of the benign and malignant airway stenosis with the nickel-titanium memory alloy tracheal stenting is good, but which can lead to the varying degrees of postoperative complications. The benign airway stenosis patient is susceptible to appear the airway restenosis within a short term,and the malignant airway stenosis patient is prone to appear the repeated pulmonary infection after a long term. A reasonable preoperative plan is needed to be formulated to minimize the incidence of complications.
