目的:探讨急性肺栓塞临床与影像诊断价值。方法:将8例临床表现、心电图、胸部x线、多普勒超声心动图、放射性核素扫描检查资料进行分析。结果:8例中男女各4例,平均年龄67岁,误诊心源性休克2例,急性心内膜下心肌梗塞、急性下壁心肌梗塞及十二指肠球部溃疡各1例。慢性支气管炎继发感染2例。以呼吸困难、咳嗽、胸痛、晕厥、休克,尚有急性肺栓塞腹痛型1例,心动过速,呼吸增快;SⅠQⅡTⅢ,TⅤ1-Ⅴ4倒置或双向;多普勒超声右心大,三尖瓣中到大量返流,肺动脉高压。肺灌注通气扫描显示大面积次大面积缺损,通气显示肺正常。结论:呼吸困难、心动过速SⅠQⅡTⅢ且随病情进展而波形加深,肺灌注通气扫描可确诊;急性肺栓塞腹痛型不应忽视。
Objective: To investigate the clinical and imaging diagnostic value of acute pulmonary embolism. Methods: Eight cases of clinical manifestations, electrocardiogram, chest X-ray, Doppler echocardiography, radionuclide scan examination data were analyzed. Results: There were 4 males and 4 females in each group, with an average age of 67 years. Two patients were misdiagnosed as cardiogenic shock, one was acute subintimal myocardial infarction, one was acute inferior myocardial infarction and the other was duodenal ulcer. Chronic bronchitis secondary infection in 2 cases. One case of acute pulmonary embolism with abdominal pain, dyspnea, cough, chest pain, syncope, shock, tachycardia, rapid breathing; SⅠQⅡTⅢ, TⅤ-V4 inverted or bidirectional; Doppler ultrasound right heart, tricuspid valve To a large number of reflux, pulmonary hypertension. Lung perfusion ventilation scans showed large sub-large area defects, ventilation showed normal lung. Conclusions: Dyspnea and tachycardia SⅠQⅡT Ⅲ may deepen with the progression of the disease. Pulmonary perfusion ventilation scans can be confirmed. Acute pulmonary embolism should not be neglected.
