  • angiography
  • In 20 patients undergoing both angiography (Angio) and echocardiography (Echo), then was excellent agreement of right pulmonary artery di-ameter measurements by the two methods: Angio = 1.06 (Echo), r = 0.93. (onlinejacc.org)
  • Thus, accurate measurement of the right pulmonary artery diameter can be achieved by echocardiography, This important information, which provides quantitative and serial assessment of right pulmonary artery diam-eter in pathologic conditions that affect its caliber, may facilitate decisions about the selection of the appropriate initial surgical procedure and the timing of subsequent angiography in patients with tetralogy of Fallot. (onlinejacc.org)
  • Children
  • Two-dimensional suprasternal notch echocardiograms of the right pulmonary artery were obtained in 50 normal infants and children to determine the right pulmonary artery diameter. (onlinejacc.org)
  • causes
  • The right pulmonary artery diameter was also measured in 37 patients with tetralogy of Fallot, 30 patients with a secundum atrial septal defect and 12 patients with pulmonary valve insufficiency of various causes. (onlinejacc.org)
  • patients
  • Pulmonary artery diameter was less than the 3rd percentile for body surface area in 16 of the 37 patients with tetralogy of Fallot, but it exceeded the 97th percentile in 17 of the 30 patients with an atrial septal defect and 8 of the 12 patients with pulmonary insufficiency. (onlinejacc.org)
  • Normal
  • These data were utilized to calculate the normal range (3rd and 97th percentiles) of right pulmonary artery diameter as a function of body surface area. (onlinejacc.org)
  • vessels
  • The largest blood vessels are arteries and veins, which have a thick, tough wall of connective tissue and and many layers of smooth muscle cells ( Figure 22-22 ). (nih.gov)
  • A study of the embryo reveals, moreover, that arteries and veins develop from small vessels constructed solely of endothelial cells and a basal lamina: pericytes, connective tissue and smooth muscle are added later where required, under the influence of signals from the endothelial cells. (nih.gov)
  • As we age, the major arteries of our bodies frequently become thickened with plaque, a fatty material with an oatmeal-like consistency that builds up along the inner lining of blood vessels. (wiktionary.org)
  • The 5th pair of vessels only form in some cases without any known contribution to the final structure of the great arteries. (wikipedia.org)
  • These vessels do not anastomose with each other, but form end-arteries. (wikipedia.org)
  • The term mesenteric artery is also used to describe smaller branches of these vessels which, particularly in smaller animals, provide a significant source of vascular resistance. (wikipedia.org)
  • when two nutrient arteries exist, they usually spring from the first and third perforating vessels. (wikipedia.org)
  • The interlobar arteries are vessels of the renal circulation which supply the renal lobes. (wikipedia.org)
  • The sigmoid arteries, two or three in number, run obliquely downward and to the left behind the peritoneum and in front of the psoas major, ureter, and internal spermatic vessels. (wikipedia.org)
  • aortic
  • The right coronary artery, originates from above the right cusp of the aortic valve. (wikipedia.org)
  • The great arteries originate from the aortic arches during embryonic development. (wikipedia.org)
  • Abnormalities in the development of the great arteries during embryonic development may lead to congenital cardiovascular defects, such as: Interrupted Aortic Arch Abnormal Right Subclavian Artery Transposition of the great arteries Some of these defects can be asymptomatic and cause no complications in patients, with others being more severe and require immediate surgery right after birth. (wikipedia.org)
  • pulmonary
  • see pulmonary artery . (wiktionary.org)
  • The great arteries are the primary arteries that carry blood away from the heart, which include: Pulmonary artery: the vessel that carries oxygen-depleted blood from the right ventricle to the lungs. (wikipedia.org)
  • The right 6th almost completely regresses with only the proximal part contributing to the base of the pulmonary arteries, while the left 6th forms the ductus arteriosus, which disappears after birth. (wikipedia.org)
  • buildup
  • Over time, plaque buildup causes arteries to become blocked completely or too narrow for blood to flow easily from your heart to the rest of the body. (dailyburn.com)
  • This buildup can narrow the arteries and restrict blood flow, which can lead to heart disease and stroke . (medicalnewstoday.com)
  • plaque
  • Cholesterol in the blood combines with other substances to create plaque , which then sticks to the walls of arteries. (dailyburn.com)
  • aorta
  • The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract. (wikipedia.org)
  • vein
  • Some anatomists may contend that there is no supreme intercostal artery, only a supreme intercostal vein. (wikipedia.org)
  • usually
  • The supraduodenal artery is an artery which usually branches from the gastroduodenal artery . (wikipedia.org)
  • They now cross the quadratus lumborum, the upper three arteries running behind, the last usually in front of the muscle. (wikipedia.org)
  • In some animals, including humans, branches of these arteries join with the marginal artery of the colon, which means that occlusion of one of the main arteries does not necessarily lead to the death of the part of the gut that it usually supplies. (wikipedia.org)
  • The perforating arteries, usually three in number, are so named because they perforate the tendon of the Adductor magnus to reach the back of the thigh. (wikipedia.org)
  • passes
  • Opposite the heads of the ribs, the sympathetic trunk passes downward in front of them, and the splanchnic nerves also descend in front by the lower arteries. (wikipedia.org)
  • lower
  • from the lower branches of the artery, a third, a fourth, or even a fifth series of arches may be formed, diminishing in size the nearer they approach the intestine. (wikipedia.org)
  • common
  • In the case of narrow passageways, chest pain (also know as angina) is common, and when arteries are blocked completely, a heart attack occurs. (dailyburn.com)
  • Endometrial arteries are divided into the common ones and the arteriovenous anastomosis. (wikipedia.org)
  • The common ones are arteries that are homologous to the arteries of the rest of the body and they enrich the endometrium of the uterus. (wikipedia.org)
  • upper
  • The spiral arteries are coiled towards the upper part of the endometrium and straight towards the base of the endometrium. (wikipedia.org)
  • symptoms
  • Additional symptoms associated with GCA are carotidynia (carotid artery pain) and the thickening of erythematous, nodular, and tender superficial temporal arteries that may have decreased or absent pulses. (news-medical.net)
  • sometimes
  • The termination of the profunda artery, already described, is sometimes termed the fourth perforating artery of Elliott after the anatomist who first dissected its course. (wikipedia.org)
