Aortic emergencies present a diagnostic and treatment challenge for emergency physicians. Both acute aortic dissection and abdominal aortic aneurysms can be difficult to recognize, and a missed or delayed diagnosis may be fatal. A high clinical suspicion and rapid patient evaluation are important. Although many patients ultimately require surgical intervention, early and aggressive attention to hemodynamic stability by the emergency physician can provide a window to definitive treatment. 相似文献

Background
Aortic dissection is an important cause of acute chest pain that should be rapidly diagnosed, as mortality increases with each hour this condition is left untreated. The diagnosis can be challenging, especially if concomitant myocardial infarction is present. Echocardiography is an important tool for the differential diagnosis.Objectives
To stress the importance of recognizing aortic regurgitation for the differentiation of myocardial infarction and aortic dissection.Case Report
An 80-year-old woman was admitted to our hospital with chest pain that was diagnosed as inferior and lateral wall myocardial infarction based on electrocardiographic findings. The diagnosis was reevaluated when aortic regurgitation was detected on echocardiography. Closer inspection of the ascending aorta revealed a dissection flap as the cause of aortic regurgitation.Conclusion
Detection of aortic regurgitation in a patient with myocardial infarction and normal valves should prompt the search for a possible aortic dissection, whether or not the dissection flap can be visualized. 相似文献3.

Ascending aortic aneurysms involving the aortic root are usually treated with replacement of the ascending aorta and the aortic valve using a composite valved conduit. However, the aortic valve is usually normal and the dysfunction is due to an impairment of the other components of the aortic root. In these cases, the aortic root can be replaced, sparing the native aortic valve. Aortic valve-sparing operations have been demonstrated to be effective and durable. This article summarizes the principal methods of valve-sparing procedures, and describes the advantages and disadvantages of each method, and their impact on patient outcomes. 相似文献

经食道心脏超声评价主动脉顺应性 总被引:4,自引:1,他引:4
以经食道心脏超声技术检测46例患者主动脉顺应性。结果显示,随年龄增高而有相应主动脉内径增宽、主动脉搏动幅度和顺应分数减低、主动脉压力相关牵引张强度和非压力相关硬化指数加。高血压状态与上述主动脉顺应性参数亦有较好相关性。认为经食道心脏超声检测主动脉顺应性具有一定临床实用价值。 相似文献

Aortic root pathology is a common cause of aortic insufficiency. Aortic root aneurysm and aortic dissection, if left untreated, carry significant risk of mortality and morbidity. Surgical treatment involves replacement of the aortic valve, sinuses and ascending aorta. A number of prosthetic options have been developed including composite valve–synthetic graft, xenograft, homograft and pulmonary autograft. The current review describes the two main indications for aortic root replacement surgery, aortic dissection and root aneurysm, and discusses the various operative strategies and outcomes. 相似文献

BackgroundAortic transection, or aortic rupture, is a rare diagnosis in trauma patients and carries a high mortality.Case ReportWe present the case of a 61-year-old man presenting to a Level I trauma center after being struck by a motor vehicle, found to have an aortic transection. He was initially hypotensive and resuscitated with blood products due to concern for hemorrhagic shock. Aortic injury was suspected after chest x-ray study demonstrated a widened mediastinum. Traumatic thoracic aortic transection with pseudoaneurysm was diagnosed on computed tomography of the aorta, and the patient was taken to the operating room for thoracic endovascular repair of the aorta.Why Should an Emergency Physician Be Aware of This?Diagnosis of aortic injury can be challenging, especially in trauma patients presenting with hypotension. Aortic injury must be suspected in patients presenting after a high-velocity mechanism injury. It is an uncommon cause of hemorrhagic shock in trauma patients and must be considered even if other traumatic injuries are identified, as it commonly occurs with other significant injuries. Although chest x-ray study can be useful, a negative chest x-ray study does not rule out aortic injury. Aortic injury is a time-sensitive diagnosis, and early identification is key to these patients surviving to receive definitive management in the operating room. 相似文献

超声心动图诊断主动脉弓离断的价值 总被引:9,自引:0,他引:9
目的探讨超声心动图诊断主动脉弓离断(IAA)的价值。分析误诊、漏诊的原因。方法对27例经手术、心血管造影及磁共振明确诊断的IAA住院患儿进行回顾性分析。男16例、女11例,年龄为1个月~18岁,平均4.5岁;IAA-A型12例,IAA-B型15例。结果全组确诊26例(96.3%),漏诊1例(3.7%);确诊病例中正确分型23例(88.5%)。分型误诊或不正确3例(11.5%)。结论超声心动图对IAA的诊断有很高的临床价值,凡肺动脉高压及肺动脉呈瘤样扩张者应仔细探查主动脉弓。 相似文献

Aortic arch anomalies are present in 1% to 2% of the general population and are commonly associated with congenital heart disease, chromosomal defects, and tracheaesophageal compression in postnatal life. The sonographically based detection of aortic arch anomalies lies in the 3‐vessel and trachea view. Although highly sensitive, this view alone does not allow identification of the aortic arch branching pattern, which prevents an accurate diagnosis. The systematic addition of a subclavian artery view as part of a standardized procedure may be useful in the differential diagnosis of these conditions. We describe the sonographic assessment of fetal aortic arch anomalies by combining 2 fetal transverse views: the 3‐vessel and trachea view and the subclavian artery view, which are included in the cardiovascular system sonographic evaluation protocol. We also review the sonographic findings and the clinical implications of fetal aortic arch anomalies. 相似文献

A 7-year-old girl was admitted because of dyspnea on exertion and palpitations. Her symptoms had gradually worsened for the last 6 months. She had physical features of the Marfan syndrome. Transthoracic echocardiography showed an ascending aortic aneurysm, severe aortic regurgitation, and mildly dilated left ventricle. Because of marked aortic aneurysm and severe aortic regurgitation, the patient was treated with a beta-blocker and an angiotensin converting enzyme inhibitor. Surgery was refused by her parents. We describe here a child with Marfan syndrome in whom significant dilatation of the ascending aorta and severe aortic regurgitation is encountered and major cardiovascular complications of Marfan syndrome were reviewed. 相似文献
