Blood rushes through the tear, causing the inner and middle layers of the aorta to split (dissect). If the blood goes through the outside aortic wall, aortic dissection is often deadly.

  2. 2022年2月14日 · 主動脈剝離 (aortic dissection)是一個不算罕見但卻是致命的主動脈大血管疾病,發生年齡常見於40至70歲之間,根據粗略統計每年大約一百萬人中有5到30人罹患此疾病,其中又以男性病患居多,且大都有高血壓病史 (2) 。. 主動脈剝離的致病機轉是因為主動脈 ...

  3. Aortic dissection (AD) occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart. [3] In most cases, this is associated with a sudden onset of severe chest or back pain , often described as "tearing" in character.

  4. 2022年11月21日 · 了解什麼是主動脈剝離(Aortic dissection)之前,得先從人體的血液循環系統說起。 血液循環系統從心臟出發,收縮後將帶氧的血液行經位於胸腔的升主動脈、主動脈弓、降主動脈,再穿過腹腔後,分成2個支流到下肢後,就能完成血液的運輸。

  5. 主動脈剝離 ( aortic dissection ,AD)又稱 主動脈夾層 (dissection of aorta),是因 主動脈 內膜 (英語:Tunica intima) 破裂,使得血液可經裂口流入主動脈壁各層之間(主要是進入中層),使主動脈壁撕裂 剝離 (英語:Dissection (medical)) ,且形成壁內 血腫 (形成真假兩腔,真腔和假腔在內膜和外膜之間)的病症 [ 3] 。 主動脈剝離形成過程中,主動脈壁沒有完全破穿,而是在壁內形成夾層,因而得名;且此顯示主動脈壁由內向外,在 組織力學 特性上存在著差異 [ 4] 。 主動脈的竇管連接部(sinotubular junction)和峽部(isthmus)為好發破裂處。

  6. 2022年7月5日 · 根據 史丹佛分類法 (Stanford Classification) ,剝離假腔影響的範圍有侵犯升主動脈的稱為 甲型主動脈剝離 (type A aortic dissection) ,未侵犯升主動脈的稱為 乙型主動脈剝離 (type B aortic dissection)。 主動脈剝離症狀. 主動脈剝離前兆「強烈胸痛」。

  7. 2024年7月31日 · Aortic dissection describes the condition when a separation has occurred in aortic wall intima, causing blood flow into a new false channel composed of the inner and outer layers of the media. Dissection most commonly occurs with a discrete intimal tear, but

  8. 2021年7月26日 · An aortic dissection is a tear in the inner aortic layer that allows blood to enter and further separate the inner and middle layers of the wall of the aorta and typically extends over a long length of the aorta in either direction and may extend into branch vessels

  10. Aortic dissection is the surging of blood through a tear in the aortic intima with separation of the intima and media and creation of a false lumen (channel). The intimal tear may be a primary event or secondary to hemorrhage within the media. The dissection may occur anywhere along the aorta and extend proximally or distally into other arteries.
