目的:介绍腹部实质性脏器损伤的CT表现和诊治中的作用。材料和方法:52例腹部实质性脏器损伤,其中脾28例,肝7例,肾12例,1例肠系膜动脉破裂,4例多脏器损伤,就诊时间平均14小时内。结果:CT易发现腹部实质性脏器不同类型不同程度的出血。肝脾损伤常伴腹腔积血,其分布在肝脾外周和肝肾间隙,肝肾间隙少量液体潴留呈带条状。腹腔内血凝块是肠和肠系膜损伤的重要诊断线索。下腔静脉肝下部分至少三个层面变扁萎陷,可能是大出血引起低血容量的一个重要征象。改进图象处理技术,可以提高检出率。结论:CT对腹部实质性脏器损伤是一种高效、迅速、方便、准确的检查方法,对确定手术方案更是必须的。
Objective: To introduce the CT manifestations of abdominal parenchymal injury and its role in diagnosis and treatment. MATERIALS AND METHODS: Twenty-two cases of abdomen injury were involved. Among them, 28 were spleens, 7 were liver, 12 were renal, 1 was mesenteric artery rupture, and 4 were multiple organ injuries. The mean time to visit was 14 hours. Results: CT easily found different types of abdominal organs of varying degrees of bleeding. Liver and spleen injury often accompanied by ascites, which is distributed in the liver and spleen peripheral and liver and kidney space, liver and kidney space was a small amount of liquid retention strip. Intraperitoneal clots are important diagnostic clues to bowel and mesenteric injury. Inferior vena cava at least three levels of the lower part of the flattened and collapsed, may be caused by bleeding bleed an important sign. Improve the image processing technology, can improve the detection rate. Conclusion: CT is an effective, rapid, convenient and accurate method for the examination of abdomen parenchyma. It is more necessary to determine the surgical plan.
