  • Stent grafts top 'gold standard' balloon angioplasty for dialysi. (bio-medicine.org)
  • FAIRFAX, Va.-- A randomized multicenter study of 190 patients at 13 medical centers shows-- for the first time-- the "superior" benefit of stent grafts over balloon angioplasty for maintaining function of dialysis access grafts in kidney failure patients who undergo dialysis. (bio-medicine.org)
  • This study-- the first large prospective controlled study of its kind-- shows that this novel therapy (stent grafts) provides clear improvement over balloon angioplasty by prolonging the function of a patient's bypass without surgery-- helping individuals avoid additional invasive procedures and time in the hospital," noted Haskal, who is also professor of radiology and surgery at the University of Maryland School of Medicine.

  • Stent grafts overwhelmingly performed better than balloon angioplasty for maintaining access in dialysis patients, providing superior patency and freedom from repeat interventions," added the lead investigator and co-author of "Stent Graft Versus Balloon Angioplasty for Failing Dialysis-access Grafts. (bio-medicine.org)
  • Nearly 51 percent of dialysis accesses treated with stent grafts remained open at six months, as compared to just 23 percent of those treated with balloon angioplasties. (bio-medicine.org)
  • insertion
  • The variable distention angioplasty balloon assembly, for insertion into a blood vessel, comprises an inner elongated, inflatable balloon having a distal portion, a proximal portion and an intermediate portion therebetween and defining therein a first chamber. (google.es)
  • However, using the cutting balloon there was a marked reduction in the luminal stenosis to 44 (15)%, facilitating stent insertion. (bmj.com)
  • CONCLUSION: Cutting balloon angioplasty followed by stent insertion is a feasible technique for the treatment of aorto-ostial lesions, meriting further investigation. (bmj.com)
  • Fluoroscopy is mainly performed to view movement (of tissue or a contrast agent), or to guide a medical intervention, such as angioplasty, pacemaker insertion, or joint repair/replacement. (wikipedia.org)
  • segments
  • After dilatation with 5-mm balloons, the angioplasty segments' cross-sectional areas decreased by an average of 31% versus 4% for the nondilated (control) segments (p less than 0.0001). (ahajournals.org)
  • radial
  • The dilation structure with variable characteristics has a first diameter and pressure characteristic curve defined by a first rate of radial expansion dependent on the Young's modulus of the inner balloon and a second diameter and pressure characteristic curve defined a second rate of radial expansion dependent upon the combined Young's modulus of the inner balloon and the outer balloon. (google.es)
  • 6. The assembly of claim 1, wherein said first rate of radial expansion of said inner balloon ranges from about 1% per atmosphere of internal balloon pressure to about 5% per atmosphere of internal balloon pressure. (google.es)
  • inflation
  • citation needed] In 1985, Sahota invented "Sahota Perfusion Balloon" which allows blood to flow to the heart muscle during inflation and prevents chest pain during the operation. (wikipedia.org)
  • novel
  • Endovascular radiation appears to be a novel technique, which, by use of either β- or γ-isotopes, has inhibited intimal thickening after overstretch balloon injury in experimental models. (ahajournals.org)
  • balloons
  • The outer elongated, inflatable balloon has a distal portion, a proximal portion and an intermediate portion therebetween positioned around the inner balloon and defines between the balloons a second chamber. (google.es)
  • Results
  • Angioplasty is easier on the person than bypass surgery and, under certain circumstances, has similar long-term results. (canada.com)
  • The excellent results of this initial and subsequent patients were critical to the rapid development and growing acceptance of the angioplasty treatment option. (wikipedia.org)
  • removal
  • This innovation utilizes a proprietary valve system that allows a physician to perform angioplasty or clot removal and perform an injection of physician-specified fluids without having to remove the guidewire or exchange devices. (prnewswire.com)
  • This angioplasty-induced vasoconstriction was prevented by endothelial denudation before angioplasty, removal of extracellular calcium, and pretreatment with indomethacin or ibuprofen. (ahajournals.org)
