Abstract:
A pregnant woman in her early 30s, at 20 weeks of gestational age, presented with recurrent haemoptysis, pleuritic chest pain and a productive cough of 6 months duration. She underwent CT pulmonary angiogram which demonstrated right pulmonary sequestration and right-sided consolidation. Pre-existing pulmonary comorbidities such as chronic inflammation, structural abnormalities or weakened blood vessels within the lungs can encourage the growth of abnormal blood vessels. During pregnancy, these dynamics can be further aggravated by increasing cardiac output to promote blood flow to the placenta and increasing oxygen delivery to the developing foetus. These changes likely cause increased blood flow to the pulmonary sequestration, resulting in haemoptysis. The patient was treated conservatively for community-acquired pneumonia with a course of oral amoxicillin 500 mg three times a day for 5 days, and she is doing well on follow-up.
摘要:
一个30出头的孕妇,在胎龄20周时,出现反复咯血,胸膜炎性胸痛和持续6个月的生产性咳嗽。她接受了CT肺血管造影检查,显示右肺隔离症和右侧巩固。预先存在的肺部合并症,如慢性炎症,肺内结构异常或减弱的血管可促进异常血管的生长。在怀孕期间,通过增加心输出量以促进血液流向胎盘并增加对发育中胎儿的氧气输送,可以进一步加剧这些动力学。这些变化可能导致肺隔离症的血流量增加,导致咯血.患者保守治疗社区获得性肺炎,口服阿莫西林500毫克,每天3次,共5天,她在后续行动中做得很好。
