  • The anterior jugular vein is directed laterally in front of the artery, but is separated from it by the Sternohyoideus and Sternothyreoideus. (iiab.me)
  • Cardiopulmonary bypass was established with cannulation of the left axillary and femoral arteries and drainage via the right femoral vein, and systemic cooling was started. (figshare.com)
  • On the grayscale images, the right common carotid artery demonstrates patency with mild intimal thickening only. (mtsamples.com)
  • On the left, the common carotid artery demonstrates intimal thickening, but is otherwise patent. (mtsamples.com)

  • The ventral end of the second develops into the ascending pharyngeal artery, and its dorsal end gives origin to the stapedial artery, a vessel which typically atrophies in humans but persists in some mammals. (wikipedia.org)

  • 50.8% CAD cases) were imaged with a multi-sequence, carotid CMR protocol at 1.5T. For each segment of the carotid, lumen area, wall area, total vessel area (lumen area + wall area), mean wall thickness and the presence or absence of calcification and lipid-rich necrotic core were recorded bilaterally. (biomedcentral.com)
  • As the vessel runs backward, its left side is in contact with the left lung and pleura. (medscape.com)
  • Today, the rate of complications from CEA versus CAS are nearly equivocal, making the choice of therapy based more on clinical presentation, medical comorbidities, and carotid artery anatomy. (radiologykey.com)
  • A distal anastomosis was performed using the open technique with 4-0 Prolene® running suture. (figshare.com)
  • The Ovation endograft main body was accurate po-sitioned in the planned position from the right side, with no specifi c reason (both iliac arteries were similarly tortuous and angled). (romanianjournalcardiology.ro)
  • it then descends within the thorax on the left side of the vertebral column, passes into the abdominal cavity through the aortic hiatus in the diaphragm, and ends opposite the lower border of the fourth lumbar vertebra by dividing into the right and left common iliac arteries. (medscape.com)
  • It descends in front of the vertebral column and ends on the body of the fourth lumbar vertebra, commonly a little to the left of the midline, by dividing into the 2 common iliac arteries. (medscape.com)
  • His showed that in the early embryo the right and left arches each gives a branch to the lungs, but that later both pulmonary arteries take origin from the left arch. (wikipedia.org)
  • Concerns regarding the technical challenges and long-term lead parameters of His Bundle Pacing (HBP) have been overcome to many extents with the development of Left Bundle Branch Area Pacing (LBBAP), and both techniques are likely to play an important role in pediatric and CHD pacing in the future.

  • Occasionally, the entire right dorsal aorta abnormally persists and the left dorsal aorta regresses in which case the right aorta will have to arch across from the esophagus causing difficulty breathing or swallowing. (wikipedia.org)
  • To supply blood to the right arm, this forces the right subclavian artery to cross the midline behind the trachea and esophagus, which may constrict these organs, although usually with no clinical symptoms. (wikipedia.org)
