Translation guide
An embolus is a medical term for a substance (such as a blood clot, air bubble, or fat globule) that travels through the bloodstream and blocks a blood vessel. This guide helps you express this concept in Japanese, primarily in medical or technical contexts.
To refer to the substance itself that causes an embolism, such as a blood clot, air bubble, or other material.
The standard medical term for 'embolus'. It refers to the object that blocks a blood vessel. Often used in compound words like 塞栓症 (embolism).
肺塞栓症は、塞栓が肺動脈を詰まらせる病気です。
Pulmonary embolism is a condition where an embolus blocks the pulmonary artery.
塞栓の原因として血栓が最も多い。
The most common cause of an embolus is a thrombus.
Another medical term for 'embolus', literally 'plug child'. Less common than 塞栓 but still used in medical literature.
Literally 'embolic substance'. Used when specifying the material of the embolus, such as fat or air.
脂肪塞栓物質が血流に乗って肺に達した。
Fat embolic material traveled through the bloodstream and reached the lungs.
血栓 (けっせん) is a thrombus, a blood clot that forms in place. 塞栓 (そくせん) is an embolus, a clot or other material that travels from elsewhere. A thrombus can become an embolus if it breaks off and moves.
深部静脈血栓症でできた血栓が塞栓となって肺に飛ぶことがある。
A thrombus formed in deep vein thrombosis can break off and travel to the lungs as an embolus.
In everyday conversation, Japanese speakers may simply describe the situation rather than use the technical term. For example, they might say '血の塊が飛んで血管を詰まらせた' (a blood clot flew and blocked a blood vessel) instead of using 塞栓.
When an embolus lodges in a cerebral blood vessel, it causes a cerebral embolism.
