概括
超声波 (US) 与计算机断层扫描血管造影 (CTA) 结合,在内血管动脉瘤修复 (EVAR) 后,提供与单独CTA可比的监测结果. 这种方法减少了辐射暴露和成本,尽管可能仍然需要额外的CTA.
科学领域:
- 血管外科 血管外科
- 医疗成像医学成像
- 放射学 放射学是一门学科.
背景情况:
- 内血管动脉瘤修复 (EVAR) 后的传统监测依赖于计算机断层扫描血管造影 (CTA),其中涉及辐射和毒对比剂.
- 超声波 (美国) 为EVAR后监测提供了一个潜在的不那么侵入性和更具成本效益的替代方案.
研究的目的:
- 评估超声波 (美国) 是否可以在现实患者队列中与CTA相比地检测EVAR后并发症.
- 评估美国和CTA联合监测与EVAR后仅CTA监测的有效性.
主要方法:
- 两组患者的回顾性比较:CTA-only监测 (n=168) 与CTA/US联合监测 (n=300) 对于腹腔大动脉动脉瘤.
- 随访包括成像数据,再干预,破裂和死亡,并对二次破裂,动脉瘤相关死亡和再干预率进行比较.
主要成果:
- 结合CTA/美国队列的患者每年需要的CT扫描比CTA-only队列的患者少.
- 组合组中的40%的患者需要额外的CTA扫描.
- 在无动脉瘤相关死亡,二次破裂或干预方面,两组之间没有发现显著差异.
结论:
- 美国和CTA联合监测的结果与EVAR后监测的CTA监测结果相似.
- 美国是EVAR监测中CTA的可行替代品,可能减少辐射暴露和成本.
- 在组合组中,需要进行大量额外的CTA,通常是由于怀疑内脏泄漏或其他与动脉瘤无关的发现.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
