钝性腹部空腔脏器穿孔及肠系膜损伤患者的64排螺旋CT影像学指征及特点分析(1)
[摘要]目的 探讨钝性腹部空腔脏器穿孔及肠系膜损伤患者的64排螺旋CT影像学指征及特点。方法 回顾性分析2015年4月～2017年6月我院收治的132例钝性腹部创伤患者的资料，按照患者的损伤情况将其分为对照组(65例，经手术证实仅有钝性实质性脏器损伤，而无空腔脏器穿孔及肠系膜损伤)与观察组(67例，经手术证实存在空腔脏器穿孔及肠系膜损伤)。两组患者均采用64排螺旋CT进行检查。比较两组患者腹腔或腹膜后积气、系膜增厚、肠管壁增厚、系膜密度增高、腹腔脂肪间隙密度增高及腹膜增厚CT征象的检出情况，分析钝性腹部空腔脏器穿孔及肠系膜损伤患者的直接CT影像學征象。结果 观察组患者的腹腔或腹膜后积气、系膜增厚、肠管壁增厚、系膜密度增高、腹腔脂肪间隙密度增高及腹膜增厚检出率高于对照组，差异有统计学意义(P<0.05)。钝性腹部空腔脏器穿孔及肠系膜损伤患者的直接CT征象为腹腔或腹膜后积气、腹腔脂肪间隙密度增高以及肠管壁增厚。结论 钝性腹部空腔脏器穿孔及肠系膜损伤的64排螺旋CT影像学特征表现为腹腔或腹膜后积气、系膜增厚、肠管壁增厚、系膜密度增高、腹腔脂肪间隙密度增高及腹膜增厚等，这些征像有助于协助诊断。

[Abstract] Objective To investigate the imaging signs and characteristics of 64-slice spiral CT in patients with blunt abdominal cavity perforation and mesentery injury. Methods A retrospective analysis of the date of 132 patients with blunt abdominal trauma admitted into our hospital from April 2015 to June 2017 was conducted. According to the injuries of patients， they were divided into the control group (n=65， blunt organ injury confirmed by surgery， without cavity perforation and mesenteric injury) and the observation group (n=67， with cavity perforation and mesenteric injury confirmed by surgery). Patients of both groups were examined with 64-slice spiral CT. The detection of CT signs of abdominal cavity or retroperitoneal pneumatosis， mesenteric thickening， intestinal wall thickening， increased mesangial density， increased abdominal fat gap density and peritoneal thickening were compared. The direct CT imaging signs of blunt abdominal cavity perforation and mesentery injury were analyzed. Results The abdominal cavity or retroperitoneal pneumatosis， mesenteric thickening， intestinal wall thickening， increased mesenteric density， increased abdominal fat gap density， and peritoneal thickening detection rates in the observation group were higher than those in the control group， and the differences were statistically significant (P<0.05). The direct CT signs of patients with blunt abdominal cavity perforation and mesenteric injury were pneumatosis in the abdominal cavity or retroperitoneum， increased density of the abdominal fat gap， and intestinal wall thickening. Conclusion The 64-slice spiral CT imaging features of blunt abdominal cavity perforation and mesenteric injury are manifested as abdominal or retroperitoneal pneumatosis， mesenteric thickening， intestinal wall thickening， increased mesenteric density， increased abdominal fat gap density， and peritoneal thickening， etc.， which are beneficial for diagnosis., http://www.100md.com(吴兆亮 涂伟岚 邹安民)
