Free-floating thrombus in ascending aorta is a rare cause of peripheral embolism with potentially fatal consequences. We report the case of a young patient with syncope and sudden lumbar pain. Computed tomographic scan revealed a large pedunculated floating mass attached to the posterior wall of the ascending aorta, probably responsible of renal embolic infarction; transthoracic echocardiography confirmed the diagnosis. Surgery was urgently performed. The thrombus was excised, and was not related to atherosclerotic disease of the aortic wall. We conclude that once diagnosis is clear, urgent surgery must be considered to avoid any further embolic complications. 相似文献

Background
Brain abscesses can develop with Tetralogy of Fallot and pulmonary anterior venous fistula with large right-to-left shunt. However, some patients exhibit cryptogenic brain abscess (CBA) in the absence of any such congenital disease or other infections. Patent foramen ovale (PFO) is a very common disease that exhibits right-to-left shunt. This study reports the potential for concern between CBA and PFO.Methods
We enrolled patients with CBA in our hospital between January 2003 and January 2013. Patients underwent transesophageal echocardiography (TEE) with contrast medium to investigate the presence of PFO.Results
Seven patients were included. Four were females, and the mean age was 67.7?±?9.2 years. In all patients, TEE failed to reveal any new findings, however, six patients had PFO, and another patient had pulmonary arteriovenous shunt. Four patients had odontopathy.Conclusion
In this study, all CBA patients exhibited right-to-left shunt. CBA might be caused by paradoxical embolization of a bacterial mass via PFO. Thus, more patients with CBA need to undergo TEE to detect PFO. 相似文献8.

A 62-year-old man presented with bilateral thromboembolic occlusion of the lower leg arteries 8 months after closure of a patent foramen ovale with an Amplatzer patent-foramen-ovale occluder (AGA Medical Corporation, Plymouth, MN). Then he developed an acute myocardial ischemia. A left heart catheter revealed thromboembolic occlusion of the right coronary artery, and echocardiography demonstrated a thrombus attached to the device within the left atrium. Cerebral computer tomography showed a new ischemic lesion. In an emergency procedure, the device and the left atrial thrombus were removed, the septal defect was closed, and a coronary artery bypass grafting was performed. The patient was discharged from the hospital in stable condition. 相似文献

BACKGROUND AND AIM: A biatrial thrombus straddling a patent foramen ovale (PFO) is rare. The optimal management is controversial. This report offers an additional report and brief review of the literature. CASE REPORT: A 72-year-old female presented with paroxysmal dyspnea. Transthoracic echocardiography showed distended right heart cavities, pulmonary artery hypertension, and a thrombus in the right atrium passing through the PFO into the left atrium. Urgent surgical embolectomy confirmed an 11.5 cm serpentine biatrial thrombus and allowed PFO closure and bilateral pulmonary embolectomy. Postoperative recovery was uneventful. CONCLUSIONS: The risk of systemic embolization during thrombolytic or heparin treatment for biatrial thrombus makes most authors recommend surgical or interventional thrombectomy and PFO closure. Given the limited number of cases, there is no evidence that any of the treatment strategies provide a better survival. 相似文献

Anesthetic management of patients presenting for posterior cranial fossa surgery in the seated position includes detection and treatment of venous air embolism. Atrial positioning of a central venous (cv) line may be verified by either X-ray or an atrial ECG tracing. We report a case where a chest X-ray film proved superior. A 26-year-old white female was scheduled for posterior cranial fossa exploration. A cv line was inserted via the left antecubital vein; the chest X-ray film documented correct positioning of the catheter tip within the atrium but an aberrant course of the superior vena cava. Echocardiography was performed in the induction room and indicated a patent foramen ovale. In view of the risk of paradoxical air embolism, surgery was postponed. Subsequent cardiologic and radiologic examinations revealed a patent foramen ovale and a persisting left superior vena cava draining into a dilated coronary sinus. Surgery was rescheduled and carried out uneventfully in the prone position. This case demonstrates: 1) an advantage of a thoracic-X-ray film compared to atrial ECG tracing as not only the catheter tip position, but also the course of the catheter can be identified; and 2) the usefulness of preoperative screening for a patent foramen ovale in patients scheduled for surgery in the seated position. 相似文献

A floating thrombus in the ascending aorta is an uncommon source of embolism. We report a case in which a floating mass in the left coronary sinus of Valsalva caused intermittent left main coronary trunk occlusion, leading to myocardial ischemia and cardiogenic shock. The mass was surgically resected. Macroscopically, the aortic wall and leaflets were normal. On histologic examination the mass was found to be a thrombus. This patient had a low level of protein C; therefore, it was presumed that the thrombus was due to protein C deficiency. 相似文献

OBJECTIVE: We determined the efficacy of surgery for acute pulmonary thromboembolism with a floating right-heart thrombus. METHODS AND RESULTS: Thrombi were diagnosed by transthoracic echocardiography and electron beam computed tomography in 4 patients with acute pulmonary thromboembolism with a floating right-heart thrombus, and thromboembolectomy was done in all patients. Surgical procedure included intermittent deep hypothermic circulatory arrest. One patient died of endobronchial hemorrhage and 3 survived. CONCLUSION: Because acute pulmonary thromboembolism with a right-heart thrombus is life-threatening, immediate thromboembolectomy is required to decrease mortality. 相似文献
