Splenic injuries are common emergencies in the setting of abdominal trauma, as the spleen is the second most frequently injured abdominal organ after the liver. The treatment of splenic injuries underwent a severe shift from operative to non-operative due to an increased awareness of the double physiological function, both immunological and hematological, of the spleen. This, in turn, led to an increased application of splenic preservation techniques. The non-operative approach has been strengthened through radiological imaging and interventional radiology. While multidetector computed tomography is mandatory in the evaluation of hemodynamically stable patients after high-energy trauma, one ultrasound (US) can be used as a first-line technique to examine patients in cases of low-energy trauma. Unfortunately, baseline US has low sensitivity in the detection of traumatic injuries. With the introduction of contrast-enhanced ultrasound (CEUS) as a reliable alternative to baseline ultrasound for low-grade abdominal trauma, the sensitivity of the US technique in recognizing traumatic abdominal lesions has strongly increased, reaching levels of accuracy similar to those of the CT. It has also been strongly recommended for use with children, as it allows for the performance of imaging techniques with the lowest dose of radiation possible. In this review, the authors aim to present the typical appearance of traumatic splenic injuries, using enhanced CEUS capability to overcome baseline US limits, and to describe the different techniques applied according to the hemodynamic stability of the patient.
脾损伤是腹部创伤中的常见急症,因为脾脏是腹部器官中仅次于肝脏的第二大最常受伤的器官。由于对脾脏免疫和血液学双重生理功能的认识不断提高,脾损伤的治疗方法从手术治疗向非手术治疗发生了重大转变。这反过来又导致了脾保留技术的应用增加。通过放射影像学和介入放射学,非手术方法得到了加强。虽然多层螺旋计算机断层扫描在评估高能创伤后血流动力学稳定的患者时是必不可少的,但在低能创伤情况下,超声(US)可作为检查患者的一线技术。不幸的是,基线超声在检测创伤性损伤方面敏感性较低。随着超声造影(CEUS)作为低级别腹部创伤中基线超声的可靠替代方法的引入,超声技术在识别创伤性腹部病变方面的敏感性大大提高,达到了与CT相似的准确度水平。它也被强烈推荐用于儿童,因为它可以使用尽可能低剂量的辐射进行成像技术检查。在这篇综述中,作者旨在展示创伤性脾损伤的典型表现,利用增强型CEUS的能力克服基线超声的局限性,并描述根据患者血流动力学稳定性应用的不同技术。
