  • breast implant
  • Free-flap breast reconstruction is a type of autologous-tissue breast reconstruction applied after mastectomy for breast cancer, without the emplacement of a breast implant prosthesis. (wikipedia.org)
  • The clinical advantage of the free-flap breast reconstruction procedure is avoidance of the medical complications-infection, malposition of the breast implant(s), capsular contracture-which occasionally occur consequent to breast-reconstruction surgery procedures that emplace breast prostheses to the mastectomy wounds. (wikipedia.org)
  • radial
  • The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. (google.co.uk)
  • In either case, when the stent is adjacent to a treatment site within the body, the sheath is retracted proximally to expose the stent for radial expansion into contact with the vessel wall. (google.com)
  • replacements
  • 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.

  • Walter Golaski (1913 in Torrington, Connecticut -1996) was an American Mechanical-Bio-Medical Engineer best known for developing Dense Knit Dacron Vascular Prostheses, which were the first practical artificial blood vessel replacements. (wikipedia.org)
  • coronary
  • 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. (mendeley.com)
  • tissue
  • Once the TRAM free flap is transposed to the woman's chest, the epigastric blood vessels are anastomosed (connected) to the internal thoracic vein to maintain the tissue viability of the reconstructed breast. (wikipedia.org)
  • because it possesses a robust blood supply, there is a low risk of tissue necrosis, either of the flap or of the adipocyte fat, and the reconstructed breast can tolerate oncologic radiotherapy. (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)
  • polymer
  • 1. An endoluminal prosthesis, comprising an elongate support wire member joined alone an entire length thereof to at least one surface of a strip of polymer cladding, the joined support wire member and polymer cladding being helically wrapped into an open cylindrical structure such that adjacent windings of the polymer cladding have overlapping regions that are bonded to one another forming said prosthesis. (google.com)
  • high
  • clarification needed] It is used in high temperature applications such as missile nose cones, rocket motors, heat shields, laboratory furnaces, in graphite-reinforced plastic, and in biomedical prostheses. (wikipedia.org)
  • Cross match of blood is routine also, as a high percentage of patients receive a blood transfusion. (wikipedia.org)
  • The force from the blood flow over the high pressure gradient from the prosthesis leads to fragmentation of red cells, and schistocyte formation. (wikipedia.org)
  • metal
  • The metal ring holds, by means of two metal supports, a disc which opens and closes as the heart pumps blood through the valve. (wikipedia.org)
  • main
  • The main concern is strangulation, where the blood supply to part of the bowel is blocked. (wikipedia.org)
  • flow
  • When blood pressure in the chamber of the heart exceeds that of the pressure on the outside of the chamber the ball is pushed against the cage and allows blood to flow. (wikipedia.org)
  • Red cells get trapped in the fibrin strands of the microthrombi and become sheared by the force of blood flow leading to schistocyte formation. (wikipedia.org)
  • mechanical
  • Schistocyte formation occurs as a result of mechanical destruction (fragmentation hemolysis) of a normal red blood cell. (wikipedia.org)
  • surgery
  • The division of the superior epigastric blood supply, by a previous surgery, precludes a pedicled TRAM flap as the feasible method for breast reconstruction. (wikipedia.org)
  • supply
  • They may be chronic, although painless, and can lead to strangulation (loss of blood supply), obstruction (kinking of intestine), or both. (wikipedia.org)
  • pressure
  • A class of drugs used to decrease hypertension, mainly by interfering with the renin kidney-blood pressure control cycle. (wikipedia.org)
  • An agent which interferes with the renin (kidney-lung-heart blood pressure control) cycle. (wikipedia.org)
