ATLANTA -- Coronary artery bypass grafts taken from the radial artery may provide short-term patency that is just as good as standard saphenous vein grafts, researchers found in a randomized trial.
However, the question of long-term patency awaits a planned, five-year angiographic follow-up, according to Steven Goldman, MD, of the Tucson VA Hospital in Arizona, who reported the results here at the American College of Cardiology meeting.
Advance PTX is designed to increase long-term patency in patients with peripheral arterial disease (PAD) and is one of the first PTA balloon catheters to be coated with paclitaxel, an antiproliferative drug that has been used successfully to reduce the risk of arterial restenosis following angioplasty in coronary disease patients.
There are a number of important factors that could cause Cardica's results to differ materially from those indicated by these forward-looking statements, including risks associated with market acceptance of Cardica's C-Port systems and long-term patency of CABG grafts completed with Cardica's C-Port systems, as well as other risks detailed from time to time in Cardica's SEC reports, including its Annual Report on Form 10-K for the year ended June 30, 2008.
recent study published in the New England Journal of Medicine has raised a number of questions about the long term patency of endoscopically harvested saphenous veins that are collected and used for coronary artery bypass grafts.
Interventional radiologists found no difference between the two age groups when it comes to "patency" or the openness of AV fistulas or accesses needed for dialysis.
Preferred access at any age: Comparison by interventional radiologists shows no difference in 'patency' or openness of arteriovenous (AV) fistulas
Stents have been used for years with success to establish and maintain patency in partially occluded coronary arteries and it seemed reasonable that they might be similarly used for the carotid arteries.
Another way of referencing the situation is to say that a woman is "losing patency."
The biological definition of patency is "the state or quality of being open, expanded, or unblocked."
