A 56-year-old female nonsmoker presented with episodic hemoptysis, without any other associated respiratory symptoms. Her medical history was notable for polycythemia rubra vera with portal vein thrombosis, which was treated with warfarin, but was complicated by portal hypertension. Esophageal varices were controlled by endoscopic band ligation. Chest radiograph and 64-slice computed tomography scanning failed to identify a culprit lesion. Bronchoscopy identified a vascular structure in the proximal trachea. A contrast-enhanced 320-multidetector row computed tomography scan of the neck showed a tortuous vascular channel in the trachea, which changed in appearance over time, consistent with a tracheal varix. The patient was changed to aspirin therapy and was evaluated by a cardiothoracic surgeon. A conservative approach was adopted, and the patient has had no recurrence of symptoms.
一位 56 岁的女性非吸烟者出现阵发性咯血，无其他相关呼吸道症状。她的病史中值得注意的是真性红细胞增多症伴门静脉血栓形成，曾用华法林治疗，但并发门静脉高压。食管静脉曲张通过内镜套扎治疗得到控制。胸部 X 线和 64 排螺旋 CT 扫描未能确定病灶。支气管镜检查发现近端气管有一个血管结构。颈部增强 320 排多层 CT 扫描显示气管内迂曲的血管通道，随时间变化而改变，符合气管静脉瘤的表现。患者改为阿司匹林治疗，并由心胸外科医生进行评估。采取了保守治疗方法，患者症状未再复发。
