The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]
The common carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch. At the throat it forks into the internal carotid artery and the external carotid ...
The proximal part of left subclavian is blocked (shaded artery). This prevents antegrade ("forward") flow to the left arm and left vertebral. As a result, flow in the left vertebral is retrograde ("backwards") towards the left arm. Flow to the brain and circle of Willis is via antegrade right and left carotid and right vertebral arteries. Specialty
During the operation, a median sternotomy is performed in order to expose and ligate the involved artery above and below the fistula. Division of the thymus and superior retraction of the innominate vein exposes the innominate artery. [5] The innominate artery should be debrided to healthy tissue and closed with a monofilament suture. [5]
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
The ligamentum arteriosum (arterial ligament), also known as Botallo's ligament, Harvey's ligament, and Botallo's duct, [1] is a small ligament attaching the aorta to the pulmonary artery. [ clarification needed ] It serves no function in adults but is the remnant of the ductus arteriosus formed within three weeks after birth .
One of the reasons affecting the rate of stenosis could be the anastomotic angle. [ 3 ] [ 4 ] In computational fluid dynamics study, the ideal anastomotic angle should be less than 30 degrees to ensure laminar flow of the blood, thus prolong the endothelial cell survival, and prevent smooth muscle proliferation within vessel wall, and clogging ...
MBTS shunt provides connection from the pulmonary artery to brachiocephalic artery or subclavian artery, while the RVPA conduit provides connection from right ventricle to pulmonary artery. [21] [5] Blalock-Taussig Shunt, a Gore-Tex conduit (a kind of plastic tubing) is used to connect the subclavian artery to the pulmonary artery. In this case ...
