Taking Care of Your Aorta 10/15/18 (Virtual Medical Symposium Series)
3:07-4:52
The aorta is the largest artery of the body so it arises from the heart, this red tube, and that's the ascending aorta and it arises and it carries all the blood to the vital organs of the body. It's about the size of a large garden hose as it exits the heart and as it gets farther away from the heart, it becomes smaller because it doesn't carry as much blood and it's divided into the sections in the chest because it ascends and descends and then into the abdominal aorta and its branches.
大動脈とは、身体の中で最も太い動脈です。心臓から出て上に伸びていきます。この部分を上行大動脈といいます。大動脈は全身の重要な臓器に血液を運んでおり、庭の水やりに使う大型のホースほどの太さです。心臓から離れると、運ぶ血液の量が少なくなるので細くなっていきます。上がって、下がって、腹部大動脈となり、分岐していきます。
Another way to look at the aorta is like this. This is a typical view. Look at it like a candy cane and you might or a cane that you hold on to to walk. So the heart is here below the aortic annulus. In Marfan and related disorders, the proximal aorta, the sinuses of valsalva where it bulges out here is the largest part and that's the part, that's abnormal in most genetic aneurysm disorders like Marfan syndrome and Loeys Dietz syndrome.
別の図で説明します。大動脈は歩く時に使う杖のような形をしています。大動脈弁輪の下に心臓があります。マルファン症候群や関連疾患では、近位大動脈やバルサルバ洞が拡張し、最も太くなります。マルファン症候群やロイス・ディーツ症候群といった遺伝性動脈瘤疾患の大部分で、この部分に異常をきたします。
Some other a aortic disorders like familial aneurysm syndromes may involve the ascending aorta and spare the sinuses, but this is the part of the aorta, the ascending aorta, that's most involved in aneurysm disease and it can be imaged very nicely by an echocardiogram or a CT scan.
家族性動脈瘤症候群を含む他の大動脈疾患では、バルサルバ洞を除く上行大動脈が関係します。上行大動脈は動脈瘤疾患の好発部位であり、心エコー検査やCTスキャンにより、鮮明な画像撮影ができます。
The part of the aorta where the great vessels to the head and neck arise is called the arch. That's the arch part and then after the blood vessel to the left arm, called the subclavian artery, is the descending aorta and at the level of the diaphragm or when the aorta leaves the chest and enters abdominal cavity, we call this the abdominal aorta and it's divided above and below the kidney arteries, the suprarenal and infrarenal aorta. So that's the aorta.
頭部や首の動脈が起こる部位が大動脈弓で、アーチ状になっています。左腕に入る動脈である鎖骨下動脈が出た後、下行大動脈になります。横隔膜の高さで腹腔に入ると腹大動脈となり、腎動脈の上下の部分は、腎上部大動脈、腎下部大動脈と呼ばれます。以上が大動脈の概要説明になります。
