  • Aorta
  • The Zenith® TX2® Low Profile TAA Endovascular Graft study is a clinical trial approved by US FDA to evaluate the safety and effectiveness of the Zenith® TX2® Low Profile TAA Endovascular Graft indicated for the treatment of patients with aneurysms/ulcers of the descending thoracic aorta having vessel structure suitable for repair. (clinicaltrials.gov)
  • The ascending aortic diameter decreased on average with 38% after 40% blood loss (range 24-62%, p = 0.018), the descending thoracic aorta with 32% (range 18-52%, p = 0.018) and the abdominal aorta with 28% (range 15-39%, p = 0.018). (biomedsearch.com)
  • Their main purpose is to maintain unimpeded forward flow through the heart and from the heart into the major blood vessels connected to the heart, the pulmonary artery and the aorta. (wikipedia.org)
  • With the descending aorta exposed, the surgeon applies a side clamp to the aorta, effectively pinching and isolating one side of the great vessel. (wikipedia.org)
  • Blood continues to flow to the body's lower half through the unisolated remainder of the aorta. (wikipedia.org)
  • Patients
  • Increased oversizing of the endograft, or additional computed tomography (CT) or IVUS imaging after fluid resuscitation for more adequate aortic measurements, may be needed in TTAI patients with considerable blood loss. (biomedsearch.com)
  • In elderly patients this usually would include ECG, urine tests, hematology and blood tests. (wikipedia.org)
  • Cross match of blood is routine also, as a high percentage of patients receive a blood transfusion. (wikipedia.org)
  • methods
  • MATERIALS AND METHODS: The circulating blood volume of seven Yorkshire pigs was gradually lowered in 10% increments. (biomedsearch.com)
  • The horseshoe kidney configuration and governing vessels, urinary duct course, and right common iliac arterial stenosis were shown by methods such as angiogram, spiral CT, and intravenous pyelogram before operation. (biomedsearch.com)
  • Hemothorax
  • We present the unusual case of a 42-year-old gentleman who entered the trauma center with a hemothorax and intermittent bright red pulsatile blood from three stab wounds in the ipsilateral supraclavicular fossa. (biomedsearch.com)
  • valves
  • Bioprosthetic valves or TEHVs were implanted as pulmonary replacements in 20 baboons: weight = 27.5 +/- 5.6 kg, height = 73 +/- 7 cm, body surface area = 0.77 m2 +/- 0.08, mean blood flow = 1.973 +/- .254 L/min, core temperature = 37.1 +/- .1 degree C, and CPB time = 60 +/- 40 minutes.

  • citation needed] However, current mechanical heart valves all require lifelong treatment with anticoagulants (blood thinners), e.g. warfarin, which requires monthly blood tests to monitor. (wikipedia.org)
  • Tissue heart valves, in contrast, do not require the use of anticoagulant drugs due to the improved blood flow dynamics resulting in less red cell damage and hence less clot formation. (wikipedia.org)
  • Caged ball valves have a high tendency to form blood clots, so the patient must have a high degree of anti-coagulation, usually with a target INR of 2.5-3.5. (wikipedia.org)
  • small
  • Baboon CPB requires modifications to include high systemic blood pressure for adequate perfusion into small coronary arteries, careful CPB weaning to prevent ventricular distention, and drug and fluid interventions to abate variable venous return related to a muscularized spleno-splanchnic venous capacity.

  • A crown (the dental prosthesis) is then connected to the abutment with dental cement, a small screw, or fused with the abutment as one piece during fabrication. (wikipedia.org)
  • To enable this, the abutment is shaped as a small connector (a button, ball, bar or magnet) which can be connected to analogous adapters in the underside of the dental prosthesis. (wikipedia.org)
  • loss
  • The procedure has not been adopted widely because it is technically challenging and blood loss can be significant. (wikipedia.org)
