• saphenofemoral junction
  • Clinical test that may be used include: Trendelenburg test-to determine the site of venous reflux and the nature of the saphenofemoral junction Traditionally, varicose veins were investigated using imaging techniques only if there was a suspicion of deep venous insufficiency, if they were recurrent, or if they involved the saphenopopliteal junction.

  • bypass graft
  • Indications: A 70 year old with history of coronary disease, status post prior bypass graft surgery presents for scheduled PCI following no in-stent restenosis of the proximal stent within the vein graft to the PDA. (aapc.com)
  • endoscopic
  • A medical instrument for endoscopic removal of the saphenous vein has an elongated shaft which has at the distal end a spatula tip and in whose proximal region is arranged a laterally projecting handle. (google.com)
  • proximal
  • The vessel is tied closed distally, the proximal portion is transected (venotomy) and gently dilated, and a cannula is introduced through the venotomy and secured in place with a more proximal ligature around the vein and cannula. (wikipedia.org)
  • The valvulotome is inserted at the distal end of the vein, guided to the proximal end, then withdrawn. (wikipedia.org)
  • clot
  • The primary goal of the study is to determine whether prasugrel administration will prevent thrombus (clot) formation within a saphenous vein graft at 12 months, as examined by optical coherence tomography. (clinicaltrials.gov)
  • arterial
  • Since the leg veins usually contain a number of valves that direct flow towards the heart, they cannot directly be used as graft, but if vein valves are removed the arterial blood can flow via the GSV to the lower leg - this is called an in situ graft procedure, a type of vascular bypass. (wikipedia.org)
  • Incidence
  • The extremely low mortality early and late postop (7%), the low incidence of Ml (16%), and the excellent functional results after extended follow-up indicate that emergency saphenous vein bypass grafting is an effective therapy for unstable angina. (ahajournals.org)
