目的：提高对肺栓塞（ＰＥ）的认识。方法：经肺核素扫描、肺动肺造影和Ｘ线胸片等方法，对２６例ＰＥ进行回顾性分析。结果：引起ＰＥ的主要危险因素仍是深静脉血栓性静脉炎（４６２％）。肺灌注显像１９例，７８９％呈双肺多发性灌注缺损，２１１％呈右肺灌注缺损；肺动脉造影６例均提示肺动脉阻塞。本组死亡率为１９２％，未治疗者为８０％，治疗者为４７％；本组病人误诊率为（７３％）。提示：ＰＥ仍为人们认识不足的疾病，误诊率较高，应予以重视。
Objective: To improve the understanding of pulmonary embolism (PE). Methods: 26 cases of PE were retrospectively analyzed by pulmonary radionuclide scan, pulmonary pulmonary angiography and X-ray. Results: The main risk factor for PE was still deep vein thrombophlebitis (462%). Pulmonary perfusion imaging in 19 cases, 78.9% showed multiple lung perfusion defects, 21.1% showed right lung perfusion defect; pulmonary arteriography 6 cases were prompted pulmonary artery occlusion. The mortality rate was 19 2% in this group, 80% of untreated patients, treatment was 4 7%; misdiagnosis rate of patients in this group was (73%). Tip: PE is still a lack of awareness of the disease, the higher the rate of misdiagnosis, should be taken seriously.
