The rate of post-intubation tracheal stenosis (PITS) varies from 10 to 22% according to the studies. Only 1-2% of these stenoses are severe or symptomatic and manifest as inspiratory dyspnea that doesn't improve under corticosteroid treatment. STPI often occurs in patients with altered general status and this complicates their management. We report the case of a 43-year old hypertensive patient with a 1-year history of haemorrhagic stroke due to hypertensive peak, who had been in a coma for 3 months, requiring prolonged intubation and tracheotomy. Tracheal cannula removal had been proven time and again, but it was impossible due to respiratory distress. ENT exam showed important subglottic stenosis above the hole due to tracheotomy. Ct scan confirmed tracheal stenosis (A, B, C). Tracheoscopy under general anesthesia objectified subglottic stenosis at 1 cm from the glottic floor. The patient underwent surgery with proximal tracheal resection of 3cm, posterior cricoid mucosectomy and cricotracheal anastomosis. Postoperative outcome was favorable. The diagnosis of PITS is sometimes difficult, but it should be suspected in any patient with dyspnoea of recent onset or with unusual dyspnoea after intubation and/or tracheotomy. Tracheal resection and anastomosis, as they have been performed in our study, are the treatment of choice for tracheal stenosis.
根据研究,气管插管后气管狭窄(PITS)的发生率在10%至22%之间。这些狭窄中只有1% - 2%是严重的或有症状的,表现为吸气性呼吸困难,在皮质类固醇治疗下无改善。PITS常发生于一般状况改变的患者,这使其治疗变得复杂。我们报告一例43岁高血压患者,因高血压急症有1年出血性中风病史,昏迷3个月,需要长期插管和气管切开。气管套管多次尝试拔除,但因呼吸窘迫未能成功。耳鼻喉检查显示气管切开部位上方声门下严重狭窄。CT扫描证实气管狭窄(A、B、C)。全身麻醉下的气管镜检查发现声门下距声门底部1 cm处狭窄。患者接受了3 cm近端气管切除术、后环状软骨粘膜切除术和环状气管吻合术。术后结果良好。PITS的诊断有时很困难,但对于近期出现呼吸困难或插管和/或气管切开后出现异常呼吸困难的任何患者都应怀疑。如我们研究中所进行的气管切除和吻合术,是气管狭窄的首选治疗方法。
