摘要:
目的 通过分析心源性肺水肿的影像特征及形成其影像特征的病理生理机制,为临床诊治提供更多可靠依据。 方法 收集我院既往收治的53例心源性肺水肿患者为研究对象,采用回顾性分析法对相关资料展开分析,探究其影像学特征及其病理生理关系。 结果 心源性肺水肿患者可以间质性肺水肿及肺泡性肺水肿为主要表现,同时常伴随心脏增大等影像学表现。左心衰竭时因心脏泵血功能下降,肺静脉压力升高,继发肺静脉毛细血管压力增高, 液体渗入肺间质继而出现间质性肺水肿,若该病理过程未及时得到纠正,液体进一步从肺间质漏出到肺泡腔就会出现肺泡性肺水肿,心源性肺水肿的不同影像学表现与疾病发展过程中的病理生理过程密切相关。结论 不同类型肺水肿及不同程度的肺水肿其影像学表现既有相似点又各具特点,但肺水肿的影像学表现始终与其病理生理机制始终紧紧相连,密切相关,临床工作中,熟悉不同肺水肿病理生理机制的差异,有助于正确快速识别疾病,协助判断病情,具有实际的临床意义。
Abstract:
Objective To analyze the image characteristics of cardiogenic pulmonary edema and the pathophysiological mechanisms that form the image characteristics so as to provide more reliable evidences for clinical diagnosis. Methods Fifty-three patients with cardiogenic pulmonary edema previously admitted to our hospital were collected as the research subjects, and the relevant data were analyzed by retrospective analysis to explore its imaging characteristics and pathophysiological relationship. Results The patients with cardiogenic pulmonary edema were mainly manifested by interstitial pulmonary edema and alveolar pulmonary edema, and were often accompanied by imaging findings such as enlarged heart. In the left heart failure, due to the decline in the pumping function of the heart, the pulmonary vein pressure increased, the secondary pulmonary vein capillary pressure increased, and the fluid penetrated into the interstitial lung and then interstitial pulmonary edema occurred. If the pathological process was not corrected in time, the fluid would further leaked into the alveolar cavity and then alveolar pulmonary edema occurred. The imaging manifestations of cardiogenic pulmonary edema were closely related to the pathophysiology during the development of the disease. Conclusion Different types and different degrees of pulmonary edemas have both imaging similarities and differences, but the imaging performance of pulmonary edema is always closely related to the pathophysiology. The differences in the pathophysiological mechanisms of different pulmonary edemas are helpful to correctly and quickly identify the disease and assist in determining the condition, and have practical clinical significance.
