Objective To compare the bronchial arteriography through multidetector-row CT (MDCT) with the digital subtraction angiography (DSA) via femoral artery, and evaluate the application value of bronchial arteriography through MDCT in the diagnosis and treatment of hemoptysis. Methods 133 cases complained of hemoptysis were examined by MDCT and DSA via femoral artery respectively to perform bronchial arteriography, and the differences of image results by two methods were compared. Results 129 cases with abnormal bronchial arteries were confirmed by DSA via femoral artery, 117 cases were checked by MDCT [ the positive rate was 90.7% (117/129 ) ] . 117 cases with abnormal bronchial arteries were confirmed by both MDCT and DSA via femoral artery and 4 cases did not detected any abnormal arteries by both methods. The coincidence rate of two methods was 91.0% (121 /133) . MDCT and DSA via femoral artery showed the similar origins of abnormal bronchial arteries. The coincidence rate of two methods was 100% . Conclusions There is a high coincidence rate betweenMDCT and DSA in detecting bronchial artery abnormalities. MDCT shows the origins of abnormal vessels clearly which could be a fist-choice of routine imagination for interventive operation.
Hemoptysis is a common respiratory emergency, and severe cases can lead to death. Patients with massive hemoptysis need emergency management at the bedside, and fully evaluation for indications and timing of tracheal intubation and transtracheal intervention. When a relatively stable state is achieved, emergency vascular intervention is performed to stop bleeding. CT plays an important role in the risk assessment and interventional treatment of hemoptysis, and it is worthy of clinical promotion and more exploratory research. This article introduces the emergency treatment for massive hemoptysis, the vascular interventional procedure, the exploration of clinical application of preoperative CT, and the clinical application value of CT for hemoptysis risk assessment. It aims to provide a better way to deal with massive hemoptysis and to apply CT to the interventional treatment of hemoptysis more reasonably for clinicians.
目的:对选择性支气管动脉栓塞术(SBAE) 治疗支气管扩张大咯血的疗效做客观评价,并就该技术的操作要点、注意事项等诸方面的技术问题做进一步探讨总结。方法:对32例内科保守治疗无危急生命的支气管扩张大咯血患者行介入法供血支气管动脉栓塞, 其中男18例, 女14例, 平均年龄46岁.结果:所有病例都成功实施了供血动脉栓塞, 术后除1例无效外均出血停止, 无严重并发症发生。结论:SBAE作为治疗支气管扩张大咯血的急救手段之一,具有创伤轻微、可重复性强、疗效高、见效快、并发症少、简便易行等特点,极具推广应用价值。
Pulmonary endometriosis (PEM) is a rare disease with diverse clinical manifestations, most commonly presenting as hemoptysis, while patients presenting solely with pulmonary nodules are less common. Here, we report three female patients (aged 32, 19, and 46 years, respectively). One patient sought medical attention due to hemoptysis during menstruation, while the other two had no obvious symptoms and were found to have pulmonary nodules during routine physical examinations. Two patients had a history of cesarean section, and one had a history of miscarriage. Pathologically, one patient of PEM showed extensive hemorrhage in the alveolar spaces, with fragmented endometrial glandular epithelium observed within the hemorrhagic foci. The other two patients exhibited proliferative endometrial glands and stroma, surrounded by old hemorrhage. Immunohistochemistry revealed that the endometrial glands and stroma in all three patients were positive for estrogen receptor, progesterone receptor, and vimentin, with CD10 positivity in the endometrial stroma. All three patients were definitively diagnosed as PEM by pathology and underwent thoracoscopic pulmonary wedge resection. Follow-up periods were 18, 31, and 49 months, respectively, with no recurrence observed in any of the patients.
