肺部疾病中血栓形成的诊断,首先要查明有无引起肺血管血栓形成的病因,如脂肪栓塞、羊水栓塞,严重创伤,休克、DIC、体外循环、大量输血、肺心病、肺炎及先天性紫绀型心脏病等。脂肪栓塞多见于严重骨折,它不仅可使肺毛细血管发生机械性阻塞,脂肪分解后产生的脂肪酸,特别是油酸脂(olein)还可进一步破坏肺毛细血管,促进或加重血栓形成。羊 Pulmonary disease thrombosis diagnosis, we must first identify whether the causes of pulmonary vascular thrombosis, such as fat embolism, amniotic fluid embolism, severe trauma, shock, DIC, cardiopulmonary bypass, massive blood transfusion, pulmonary heart disease, pneumonia and congenital Cyanotic heart disease and so on. Fat embolization is more common in severe fractures, it not only mechanical obstruction of pulmonary capillaries, fatty acids produced after lipolysis, especially olein (olein) can further damage the pulmonary capillaries, promote or aggravate thrombosis. sheep
