Abstract：
OBJECTIVE: This case series aims to provide a comprehensive description of the utilization of doppler ultrasonography (USG) and computerized tomography angiography (CTA) in evaluating patients with earthquake-induced crush injuries in the emergency department (ED).
METHODS: This retrospective case series was conducted on 11 patients who presented with crush injuries following a seismic event. These patients underwent initial assessment using doppler USG, with CTA performed when deemed necessary. Clinical outcomes and diagnostic findings were systematically reviewed.
RESULTS: A cohort of 11 earthquake-related crush injury patients (six females, five males; age 3-59 years), predominantly with lower extremity injuries, with entrapped durations that ranged from 12 to 128 hours. Transport centers received patients from both affected regions and nearby provinces. Initial X-rays identified fractures in two cases. Doppler USG and subsequent CTA were employed for vascular evaluation, with CTA confirming doppler USG findings. Of the 11 patients, five exhibited abnormal doppler USG findings. Four patients required dialysis and four underwent amputation surgery. Fasciotomy and debridement procedures were performed in five and seven patients, respectively. Three patients received hyperbaric oxygen therapy (HBOT).
CONCLUSIONS: Doppler USG emerged as a dependable tool for assessing vascular injuries in earthquake-related crush injuries, offering an effective alternative to CTA without the associated contrast agent risks. These findings underscore the need for further research to establish definitive imaging guidelines in these challenging clinical scenarios.

摘要：
目的：本系列病例旨在全面描述多普勒超声（USG）和计算机断层扫描血管造影（CTA）在评估急诊科（ED）地震所致挤压伤患者中的应用。
方法：本回顾性病例系列是针对11例地震事件后出现挤压伤的患者进行的。这些患者使用多普勒USG进行了初步评估，必要时进行CTA。系统评价临床结果和诊断结果。
结果：11名地震相关挤压伤患者（6名女性，五名男性；3-59岁），主要是下肢受伤，截留持续时间从12到128小时不等。运输中心接收了来自受影响地区和附近省份的患者。最初的X线检查确定了2例骨折。多普勒USG和随后的CTA用于血管评估，CTA证实了多普勒USG的发现。在11名患者中，5例表现出异常的多普勒USG结果。四名患者需要透析，四名患者接受了截肢手术。对5例和7例患者进行了筋膜切开术和清创术，分别。3例患者接受高压氧治疗（HBOT）。
结论：多普勒USG成为评估地震相关挤压伤血管损伤的可靠工具，提供CTA的有效替代方案，而没有相关的对比剂风险。这些发现强调了需要进一步研究以在这些具有挑战性的临床场景中建立明确的成像指南。
