自发孤立性腹部小动脉壁内血肿的CT影像诊断

CT imaging diagnosis of spontaneous solitary abdominal wall hematoma of small arteries

目的:探讨自发孤立性腹部小动脉壁内血肿的CT征象及诊断价值。方法:搜集2016年1月—2017年8月23例腹部小动脉壁内血肿,男性19例,女性4例;年龄从41岁至71岁。结果:部位:肠系膜上动脉主干9例;肠系膜上动脉主干及全部、单发分支9例;腹腔干、肝总动脉1例;腹腔干、肝总动脉、脾动脉1例;脾动脉、肝总动脉1例;胃左动脉1例;腹腔干、肠系膜上动脉1例。(1)CT平扫均显示血管增粗,内见新月形或环形、条状密度增高;CTA示血管增粗伴管壁增厚无强化,管腔狭窄。(2)可合并内膜渗漏、破裂出血、缺血性肠病及继发夹层。结论:自发孤立性腹部小动脉壁内血肿的CT表现典型,CTA是诊断该病的快速、合适的影像学检查方法。

Objective To investigate the value of CT signs and diagnosis of spontaneous isolated abdominal artery intramural hematoma. Methods: Collected from January 2016-2017 year in August 23 cases of abdominal artery intramural hematoma, 19 cases of male, 4 female; age from 41 to 71 years of age; the patients were acute abdominal pain. Results:Position: superior mesenteric 9 cases of artery; superior mesenteric artery and all single branch in 9 cases; 1 cases of celiac and hepatic artery; celiac artery, hepatic artery, 1 cases of splenic artery; splenic artery, 1 cases of hepatic artery; 1 cases of left gastric artery; celiac, superior mesenteric artery in 1 cases:.CT the plain Showed vascular thickening, see the crescent shaped or circular, strip density increased; CTA showed vascular thickening and thickening of the wall without enhancement.The stenosis with perivascular exudation, hemorrhage, ischemic bowel disease and secondary dissection. Conclusion:spontaneous isolated abdominal arteriolar wall hematoma showed typical CT, CTA the diagnosis of this disease is rapid, the appropriate method of imaging.
