摘要
目的 :分析迟发性脾破裂的临床CT特点 ,旨在为临床诊断提供客观依据。方法 :11例病人伤后至就诊时间为2～ 14天 ,CT先按常规平扫 ,其中 9例加做了强化检查。 4例经手术治疗 ,7例保守治疗并追踪随访。结果 :(1)实质血肿 5例 ,其 3例为界限清楚的低密度“血湖”影 ,2例呈不规则低密度“裂隙”影。 (2 )包膜下血肿 3例 ,呈边界清楚光滑的“新月形”或“半月形”低密度区。 (3)混合血肿 2例 ,表现为实质血肿与包膜下血肿并存。 (4)脾挫裂伤 1例 ,表现为弥漫性低密度区内有斑片状高密度出血影。结论 :CT表现具有特征性 。
Objective:To analyse CT features of delayed rupture of spleen after blunt abdominal trauma.Methods:A total of 11 patients with blunt abdominal trauma were studied.All CT scans were obtained 2～14 days after trauma.Noncontrast scanning was made on all patients.The IV contrast material was administered in 9 of them.Confirmation of the CT interpretations was made at surgery in 4 patients,the remaining 7 patients were confirmed by follow up CT or by clinical following.Results:(1) Of the 11 patiets,5 solid hematomas within the spleen were found,3 of them were lake-like in shape with clear edge,The remaining 2 hematomas appeared as irregular cleft.(2)3 cases of subcapsular hypodense hematomas were found,performed as crescent shape with clear edge.(3)2 cases of mixed solid and subcapsular hematomas were found,the mixed hematomas were connected by hypodense channels across the spleen.(4)1 cases of contusion and laceration of the spleen was found,appeared as wide-ranging hypodense lesion with pieces of hyperdense hematomas in it.Conclusion:CT findings of delayed splenic rupture were specific,it can provide useful informaion to guide the therapy.
