【摘要】：目的通过与增强CT对比,探讨超声造影在创伤性脾破裂诊断和分级中的应用,并分析创伤性脾破裂超声造影定量参数的临床价值。方法回顾性分析43例经手术或临床证实的创伤性脾破裂患者的超声造影表现,与增强CT比较诊断和分级性能,并分析损伤区及正常脾实质造影剂到达时间、达峰时间、峰值强度、流出时间。结果 43例创伤性脾破裂患者,超声造影和增强CT诊断创伤性脾破裂的准确率均为97.7%,超声造影分级准确率为93.0%,增强CT分级准确率为90.7%,两种方法统计学比较差异均无统计学意义(P0.05);脾破裂损伤区时间-强度曲线表现为"慢上慢下型",脾破裂各分级损伤区间及与正常脾组织间造影剂AT、TTP和WT比较差异无统计学意义(P0.05),脾破裂各分级损伤区间及与正常脾组织造影剂PI两两比较差异有统计学意义(P0.01)。结论超声造影和增强CT在创伤性脾破裂的诊断和分级中有很好的一致性,根据峰值强度可判断创伤性脾破裂的严重程度,可为临床医师治疗方案的选择提供帮助。
[Abstract]:Objective to explore the application of contrast-enhanced CT in the diagnosis and grading of traumatic splenic rupture and to analyze the clinical value of quantitative parameters of the contrast-enhanced ultrasonography. Methods the ultrasonographic findings of 43 patients with traumatic splenic rupture confirmed by surgery or clinic were retrospectively analyzed. The diagnostic and grading performances were compared with those of enhanced CT. The time of arrival and peak time of contrast media in the injured area and normal splenic parenchyma were analyzed. Peak intensity, outflow time. Results 43 patients with traumatic splenic rupture, The accuracy of contrast-enhanced CT and contrast-enhanced CT in the diagnosis of traumatic splenic rupture was 97.77.The accuracy of contrast-enhanced CT and contrast-enhanced CT was 93.0 and 90.7 respectively. There was no significant difference between the two methods in the diagnosis of traumatic splenic rupture (P 0.05). The intensity curve showed "slow upper and lower type", and there was no significant difference between each grade injury interval of spleen rupture and the contrast medium ATTTP and WT between spleen rupture and normal splenic tissue (P 0.05), and there was no significant difference between each grade injury interval of spleen rupture and normal splenic tissue angiography. The difference of Pi was statistically significant (P 0.01). Conclusion Contrast-enhanced CT is consistent in the diagnosis and grading of traumatic splenic rupture. According to the peak intensity, the severity of traumatic splenic rupture can be judged, and it may be helpful for clinicians to choose the treatment scheme.
