It supplies innervation to all of the intrinsic muscles of the larynx, except for the cricothyroid muscles, as well as sensation to the larynx below the level of the vocal cords. Aortic arch; Aortic bifurcation; Apical axillary nodes; Appendicular nodes; Appendix; Arch of azygos vein; the thoracic and abdominal aorta and its major branches. inferior border of 2L: superior border of the aortic arch, i.e. The horizontal fissure is highly variable and can be found to be incomplete or absent in some patients. The CTA radiology report should include at least: proximal and distal extent of dissection. Relations. Structure. abuts 4L; Station 3A and 3P: pre-vascular and retrotracheal nodes. These are the anterior branches of spinal nerves L1-L3. Normally, the aorta ascends in the superior mediastinum to the level of the sternal notch before arching posteriorly and descending in the left hemithorax. Stable and secured anatomical anchoring and atraumatic sealing are achieved with the proprietary Dock and Lock modular system. Deviation of the azygoesophageal line is caused by: Hiatal hernia; Esophageal disease Polymyalgia is present in 27-53% of those with Temporal Arteritis; Prevalence: 500 per 100,000 over age 50 years; Rarely occurs under age 50 years; Average age of presentation: 72 years (peak age 70-80 years old) Blood vessels function to transport blood.In general, arteries and arterioles transport oxygenated blood from the lungs to the body and its organs, and veins and venules transport deoxygenated blood from the body to the lungs.Blood vessels also circulate blood throughout the circulatory system Oxygen (bound to hemoglobin in red blood cells) is the most critical nutrient carried by 820 Jorie Blvd., Suite 200 Oak Brook, IL 60523-2251 U.S. & Canada: 1-877-776-2636 Outside U.S. & Canada: 1-630-571-7873 There is an increased incidence with age and the greater The suprasternal view is best for visualizing the aortic arch, whereas the aortic root and ascending aorta are best seen in the left (and sometimes right) parasternal projection. It gives off many branches, including the posterior interventricular artery, the right marginal artery, the conus artery, and the sinoatrial nodal artery. The left bronchial arteries (superior and inferior) usually arise directly from the thoracic aorta.. Imaging has a key role in active surveillance. The pulmonary trunk gives off various branches. The idea is that the stent-graft side branches will provide a bridge to reduce the distance from the main body to the visceral artery the application of EVAR for these more complex aortic pathologies and those involving the thoracoabdominal aorta and aortic arch(38). Right-sided aortic arch is a type of aortic arch variant characterized by the aortic arch coursing to the right of the trachea. Of these patients, 80% have a right-sided aortic arch. B and C. Aortic arch views and diagram. Variant anatomy. Thoracic aortic disease, for the purpose of this GeneReview, refers to thoracic aortic aneurysms and aortic dissections (TAAD). Arterial supply Related pathology. Coronary arterial dominance is defined by the vessel which gives rise to the posterior descending artery (PDA), which supplies the myocardium of the inferior third of the interventricular septum.. Dr. Thomas L. Forbes is the Surgeon-in-Chief and James Wallace McCutcheon Chair of the Sprott Department of Surgery at the University Health Network, and Professor of Surgery in the Temerty Faculty of Medicine at the University of Toronto. Lumbar plexus Plexus lumbalis 1/4 Blood supply The psoas major muscle is supplied mainly by the iliolumbar branch of the internal iliac artery. fornix gastricus: refers to the arch-shaped superior margin of the fundus of the stomach. Branches and supply. A thoracic aortic aneurysm Posterior circulation ischaemic stroke is a clinical syndrome associated with ischaemia related to stenosis, in situ thrombosis, or embolic occlusion of the posterior circulation arteriesthe vertebral arteries in the neck, the intracranial vertebral, basilar, and posterior cerebral arteries, and their branches (fig 1 ). A stroke is a medical condition in which poor blood flow to the brain causes cell death. A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli They are affected by a wide range of pathology that results in a diverse range of illnesses. Both cause parts of the brain to stop functioning properly. Innervation Psoas major is innervated by branches of the lumbar plexus. Additionally, it serves as the insertion site for the muscles of the Epidemiology. Situs inversus with levocardia (which is much rarer: 0.00005%) congenital heart disease is found in 95% of patients 4. Closely associated with Polymyalgia Rheumatica. anteriorly: left lobe of liver, anterior abdominal wall, left hemidiaphragm. It is bordered on the left side by the esophagus. Gross anatomy. presence of thrombosis in the false lumen. anastomosis with the anterior spinal artery, supplying arterial blood to the spinal cord from T8 to the conus medullaris 3; Variant anatomy. A related variant, also known as truncus bicaroticus, is the origin The feared complication is rupture which is a surgical emergency due to its high mortality. These are the anterior branches of spinal nerves L1-L3. associated other forms of AAS. It originates superolaterally at the deep inguinal ring.This opening occurs along the inguinal ligament (of Poupart) at the midpoint between the anterior superior iliac spine (ASIS) and the pubic tubercle; also known as the midpoint of the inguinal There are typically two left and one right bronchial arteries. external carotid artery (rare) 8, 9. common carotid artery (rare) 9. internal carotid artery (rare) 9. origin from the distal aortic arch with an aberrant retro-esophageal course (very rare) - see case 18 The lungs are the functional units of respiration and are key to survival.They contain 1500 miles of airways, 300-500 million alveoli and have a combined surface area of 70 square meters (half a tennis court). posteriorly: anterior wall of lesser sac, stomach bed. Anatomy Landmarks. 43. and 44. Most hearts (80-85%) are right dominant where the PDA is supplied by the right coronary artery (RCA).The remaining 15-20% of hearts are roughly equally divided superior border: thoracic inlet; inferior border: carina; 3A: prevascular - anterior to the great vessels (superior vena cava on the right, left common carotid artery on the left), posterior to the sternum Clinical Characteristics: Heritable Thoracic Aortic Disease. The horizontal fissure arises from the right oblique fissure and follows the 4 th intercostal space from the sternum until it meets the oblique fissure as it crosses right 5 th rib 1.. aortic size (largest orthogonal measurement) involvement and supply (from true or false lumen) of aortic branches. aortic arch origin of the left vertebral artery: incidence ~5% (range 3.1-8.3%) second (not first) branch of the subclavian artery. 1) the thoracic aorta at a common trunk with the right 3rd posterior intercostal artery; 2) the superior bronchial artery on the left side The coccyx (plural: coccyges) is the series of rudimentary vertebrae forming the caudal termination of the vertebral column and is positioned inferior to the apex of the sacrum.The coccyx is one leg of the tripod formed in conjunction with the ischial tuberosities for support in a seated position. As outlined above the origin of the artery of Adamkiewicz is quite variable and can extend from mid-thoracic to lumbar levels 3: lumbar arteries at the level of L1 or L2 (10%) The left circumflex artery follows the left part of the coronary sulcus, running first to the left and then to the right, reaching nearly as far as the posterior longitudinal sulcus.There have been multiple anomalies described, for example the left circumflex having an aberrant course from the right coronary artery.. Subclavian steal phenomenon refers to steno-occlusive disease of the proximal subclavian artery with retrograde flow in the ipsilateral vertebral artery.. Subclavian steal syndrome is the same as subclavian steal phenomenon with the addition of cerebral ischemic symptoms.. One of them is the right interlobar artery. Up to 20% of patients with situs inversus can have Kartagener syndrome 3 which comprises a subgroup of primary ciliary dyskinesia. Abdominal aortic aneurysms (AAA) are focal dilatations of the abdominal aorta measuring 50% greater than the proximal normal segment, or >3 cm in maximum diameter. Zenker diverticulum, also known as a pharyngeal pouch, is a posterior outpouching of the hypopharynx, just proximal to the upper esophageal sphincter through a weakness in the muscle layer called the Killian dehiscence. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or Variant anatomy of the aortic arch occurs when there is failure of normal aortic development.It results in a number of heterogenous anomalies of the aorta and its branch vessels.

The right interlobar artery typically measures 16 mm in males and 15 mm in females on a PA chest radiograph 6. Department of Radiology of the Loyola University Medical Center, USA. Branches. The recurrent laryngeal nerve (RLN) branches off the vagus nerve (cranial nerve X) and has an indirect course through the neck. Indicated for a wide range of aortic pathologies, including arch aneurysms, thoracic dissections, and PAU, NEXUS is designed to overcome the specific challenges of the aortic arch anatomy. Terminology. The aorta and its major branches can be visualized with echocardiography using a variety of imaging fields as well as methods of ultrasound. If a normal pouch becomes enlarged, it is termed a lateral pharyngeal diverticulum. The right coronary artery originates above the right aortic sinus above the aortic valve. The right RLN branches from CN X around the level of T1-T2 Spontaneous reflux extends to level of aortic arch. Description. The aortic arch gives rise to the right innominate or brachiocephalic (RIA), left common carotid (LCA), and left subclavian (LSA) arteries. location of the intimal tear. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Heritable thoracic aortic disease (HTAD) refers to thoracic aortic disease caused by mutation of a gene that confers a high risk for TAAD (see Causes). Each lung weighs approximately 1.1 kg. Protrusion of lateral pharyngeal wall through thyrohyoid membrane at site of penetration by laryngeal vessel and nerve branches. The aortopulmonary window is the mediastinal region bounded anteriorly by the ascending aorta, posteriorly by the descending aorta, cranially by the aortic arch, inferiorly by the left pulmonary artery, medially by the ligamentum arteriosum, and laterally by the pleura and left lung. Dr. Tom Forbes Editor-in-Chief. Innervation Psoas major is innervated by branches of the lumbar plexus. Gross anatomy. Structure. Lumbar plexus Plexus lumbalis 1/4 Blood supply The psoas major muscle is supplied mainly by the iliolumbar branch of the internal iliac artery. Bovine arch is the most common variant of the aortic arch and occurs when the brachiocephalic (innominate) artery shares a common origin with the left common carotid artery.. A bovine arch is apparent in ~15% (range 8-25%) of the population and is more common in individuals of African descent. The single right bronchial artery usually arises from one of the following: . The azygo-esophageal recess is the region inferior to the level of the azygos vein arch in which the right lung forms an interface with the mediastinum between the heart anteriorly and vertebral column posteriorly. The arch The aortic arch arises from the space between the right (RA) and left (LA) atria, and therefore, its origin is some distance away from the anterior chest wall. The inguinal canal is an oblique intramuscular slit that may range from 3 5 cm long in an adult. In human anatomy, the subclavian arteries are paired major arteries of the upper thorax, below the clavicle.They receive blood from the aortic arch.The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. It passes through the right coronary sulcus (right atrioventricular groove), towards the crux of the heart.
