“…However, other mechanisms may be involved in the occurrence of syncope once a pulmonary embolism has developed, such as vasodepressor or cardioinhibitory mechanisms. [26][27][28] In addition, when a clot dislodges from the venous system and lodges in the pulmonary circulation, it may induce arrhythmias when it passes through the heart. Hence, even smaller clots could be a potential cause of syncope.…”

BACKGROUNDThe prevalence of pulmonary embolism among patients hospitalized for syncope is not well documented, and current guidelines pay little attention to a diagnostic workup for pulmonary embolism in these patients. METHODSWe performed a systematic workup for pulmonary embolism in patients admitted to 11 hospitals in Italy for a first episode of syncope, regardless of whether there were alternative explanations for the syncope. The diagnosis of pulmonary embolism was ruled out in patients who had a low pretest clinical probability, which was defined according to the Wells score, in combination with a negative d-dimer assay. In all other patients, computed tomographic pulmonary angiography or ventilation-perfusion lung scanning was performed. RESULTSA total of 560 patients (mean age, 76 years) were included in the study. A diagnosis of pulmonary embolism was ruled out in 330 of the 560 patients (58.9%) on the basis of the combination of a low pretest clinical probability of pulmonary embolism and negative d-dimer assay. Among the remaining 230 patients, pulmonary embolism was identified in 97 (42.2%). In the entire cohort, the prevalence of pulmonary embolism was 17.3% (95% confidence interval, 14.2 to 20.5). Evidence of an embolus in a main pulmonary or lobar artery or evidence of perfusion defects larger than 25% of the total area of both lungs was found in 61 patients. Pulmonary embolism was identified in 45 of the 355 patients (12.7%) who had an alternative explanation for syncope and in 52 of the 205 patients (25.4%) who did not. CONCLUSIONSPulmonary embolism was identified in nearly one of every six patients hospitalized for a first episode of syncope.

“…Este achado ocorre em 7 a 18% dos casos de EP confirmado 3,4,5,6 . A paciente do caso ainda apresentou sintomas menos comuns da EP, como a síncope, sugerindo uma carga trombótica maior, e choque, raro, que indica EP central ou reserva hemodinâmica gravemente reduzida 7,8 . A ocorrência de trombo em trânsito no AD é um evento raro e de grande importância quando detectado.…”

A detecção de um trombo em movimento na realização de um ecocardiograma é um evento raro. Relata-se o caso de uma paciente feminina, 66 anos, admitida com quadro de choque e submetida a realização de ultrassonografia à beira de leito, visualizando trombo saindo da veia cava para átrio direito e passando pela valva tricúspide até o ventrículo direito, direcionando com maior efetividade ao diagnostico e tratamento de tromboembolismo pulmonar. Demonstra-se a importância do conhecimento pratico e acessibilidade da ultrassonografia à beira de leito no atendimento de Emergência do Hospital Universitário Professor Polydoro Ernani de São Thiago.

“…В целом примерно у каждого шестого больного (17,8 %) с синкопальным состоянием при обследовании была подтверждена ТЭЛА. В исследовании 182 больных с подтвержденной ЛЭ K. Keller et al обнаружили пресинкопальные или непосредственно синкопальные состояния у 11 % больных [15]. Кроме того, изучается прогностическая значимость и взаимосвязь синкопе при ТЭЛА с другими клиническими проявлениями.…”

Н есмотря на всевозможные меры, предпринимаемые для своевременной диагностики и адекватного лечения тромбоэмболии легочной артерии [ТЭЛА или легочной эмболии (ЛЭ)], это заболевание занимает крайне важное положение в клинической практике врача любого профиля [1, 2]. Проблема ТЭЛА сохраняет свою высокую актуальность благодаря широкой распространенности, трудностям ее диагностики и лечения, непредсказуемости клинического течения, а также весьма высокой летальности [3, 4]. Венозный тромбоэмболизм (ВТЭ), включающий в себя ЛЭ и венозный тромбоз [5, 6], является распро
