Embolism is the mobilization of a thrombus, a clot.

栓塞是血栓、血块的活动。

The most common pre-hepatic cause is portal vein obstruction, like when there's a thrombus occluding the portal vein and blocking blood flow.

最常见的肝前型病因是门静脉阻塞，例如当有栓子阻塞门静脉血流时。

What about the option of excluding the presence of a left atrial appendage thrombus right now?

现在排除左耳血栓存在的可能性如何？

He also coined the terms thrombus, a clot of coagulated blood, and embolism, when a blood clot blocks an artery.

他还创造了“血栓” 一词，指凝结的血液块，以及“栓塞” 一词，当血块阻塞动脉时即发生栓塞。

Long-term treatment to prevent future thrombi from forming can include anticoagulant medications like warfarin or heparin, which inhibit the clotting cascade and prevent clot formation.

预防DVT的期疗法包括华法林、肝素等抗凝药物的使用，可以阻断凝血反应。

The major source of thromboembolism and stroke in non-valvular AFib is formation of thrombus in the left atrial appendage where flow is relatively stagnant.

非瓣膜性房颤中，血栓栓塞和卒中的主要来源是左耳内血栓的形成，此处血流相对滞缓。

Finally, with protein C or S deficiency, there can be warfarin induced skin necrosis, which means tiny thrombi can form in the blood vessels of the skin, causing skin necrosis.

此外，患者身上还可能出现华法林导致的死，也就是说在血管中形成小血栓，导致死。

But remember, even if thrombus is not present, the patient should have at least 4 weeks of anticoagulation after the cardioversion because of the stunning risk.

但请记住， 即便未发现血栓，患者在电复律后仍需至少接受4周的抗凝治疗， 以降低房顿抑带来的风险。

Following conversion from prolonged AFib to sinus rhythm, atrial mechanical function can be delayed for weeks, so-called atrial stunning, such that thrombi can form even during sinus rhythm.

在期房颤转为窦性律后，房的机械功能可能会有数周的延迟，即所谓的“房顿抑” ， 即使在窦性律期间也可能形成血栓。

Therefore, he should be either initiated on anticoagulation with cardioversion deferred for at least three weeks after uninterrupted anticoagulation or evaluated to exclude the presence of a left atrial appendage thrombus.

因此，应启动抗凝治疗，并在连续抗凝至少三周后考虑脏复律，或者评估以排除左耳血栓的存在。

Most commonly, transesophageal echocardiography is used to evaluate for left atrial appendage thrombus, although cardiac computed tomography and geography has been demonstrated to have excellent sensitivity and specificity as well.

通常情况下， 经食管超声动图用于评估左耳血栓，尽管脏计算机断层扫描和地理定位也显示出极佳的敏感性和特异性。

People who died from sudden cardiac death, they'll take the thrombus or the embolus that occluded that coronary artery and they basically biopsy it and they find oral bacteria in that plaque that caused the heart attack or stroke.

因突发脏死亡而去世的人，他们会取下堵塞冠状动脉的血栓或栓子进行活检， 发现导致脏病发作或中风的斑块中含有口腔细菌。
