• lung
  • The largest pulmonary veins are the four main pulmonary veins, two from each lung that drain into the left atrium of the heart. (wikipedia.org)
  • An inferior and superior main vein drains each lung, so there are four main veins in total. (wikipedia.org)
  • The anterior thoracic wall, the airways and the pulmonary vessels anterior to the root of the lung have been digitally removed in order to visualize the different levels of the pulmonary circulation. (wikipedia.org)
  • Computed tomography of a normal lung, with different levels of pulmonary veins. (wikipedia.org)
  • 50%), moderate or severe mitral or aortic valve disease, or lung disease (prior tuberculosis or chronic obstructive pulmonary disease, GOLD classes III-IV). (hindawi.com)
  • Medical records and catheterization reports were reviewed for: symptoms, flow to affected lung quadrant, time from PVI to diagnosis of PVO, anatomic characteristics of occluded veins, and procedural details. (ahajournals.org)
  • the vein draining the medial bronchopulmonary segment of the middle lobe of the right lung. (drugs.com)
  • Results on mice (C57BL/6 and BALBc) and rats (Wistar) revealed that cardiomyocytes regularly extend from the hilus along venous vessels into the lung tissue surrounding individual intrapulmonary veins of varying diameters (70-250µm). (medsci.org)
  • In humans (autopsies, n=20) extrapericardiac cardiomyocytes were only found in 23 out of 78 veins and showed an incomplete sleeve at the lung hilus. (medsci.org)
  • Alveolar capillary dysplasia (ACD, sometimes denoted ACDMPV when including misalignment of the pulmonary veins) is a type of diffuse developmental disorder of the lung. (wikipedia.org)
  • vessels
  • Subsequently the common trunk and the two vessels forming it expand and form the vestibule or greater part of the atrium, the expansion reaching as far as the openings of the four vessels, so that in the adult all four veins open separately into the left atrium. (wikipedia.org)
  • Veins are blood vessels that carry blood toward the heart. (wikipedia.org)
  • The colour of a vein can be affected by the characteristics of a person's skin, how much oxygen is being carried in the blood, and how big and deep the vessels are. (wikipedia.org)
  • Veins are also called "capacitance vessels" because most of the blood volume (60%) is contained within veins. (wikipedia.org)
  • After taking up cellular waste and carbon dioxide in capillaries, blood is channeled through vessels that converge with one another to form venules, which continue to converge and form the larger veins. (wikipedia.org)
  • artery
  • Behind the pulmonary artery is the bronchus. (wikipedia.org)
  • coronal maximum intensity projection image, figure 1C ) showed a thin right pulmonary artery (PA), with fewer and thinner branches than normal. (bmj.com)
  • Blalock's surgical technician, Vivien Thomas, had earlier developed for another purpose a procedure involving the anastomosis, or joining, of the subclavian artery to the pulmonary artery. (wikipedia.org)
  • venules
  • After their passage through body tissues, capillaries merge once again into venules, which continue to merge into veins. (wikipedia.org)
  • catheterization
  • Surgery and catheterization to widen the narrow veins is usually a short-term solution since the obstruction typically recurs. (nih.gov)
  • cardiac
  • 3 Affected patients most often become symptomatic in the first few months to years of life, frequently have 1 or more additional cardiac anomalies, and have no active inflammation in or around the involved segments of vein. (ahajournals.org)
  • Animal and human histological studies on pulmonary veins (PVs), which date back to the 19th century, reported the presence of cardiac cells beyond the atrio-venous junctions [ 1 - 5 ]. (medsci.org)
  • Tunica
  • Microscopically, veins have a thick outer layer made of connective tissue, called the tunica externa or tunica adventitia. (wikipedia.org)
  • balloon
  • Patients with severely hypoplastic veins had staged intervention with initial balloon angioplasty followed by stenting 2-4 months later to allow for vessel growth. (ahajournals.org)

  • This is usually performed by high-output pacing of the right phrenic nerve proximal to its intersection with the right superior PV from the superior caval vein (Figure 1, asterisk), and manual palpation of the resultant diaphragm contractions. (acc.org)
