Nursing and midwifery practice for maintenance of vascular access device patency. A cross-sectional survey [PDF]
International Journal of Nursing Studies, 2015 BackgroundUp to 85% of hospital in-patients will require some form of vascular access device to deliver essential fluids, drug therapy, nutrition and blood products, or facilitate sampling.

How to Prolong the Patency of Vascular Access
2015Prolonging the patency and limiting the complications of a functioning hemodialysis (HD) access require a multidisciplinary approach. It begins with careful access planning that is executed and continually reinforced by physicians and facility staff encouraging active patient participation.

Long-Term Patency of Solid-Wall Vascular Prostheses
Archives of Surgery, 1965SEVERAL discoveries over the past 15 years have progressively led to the recent suggestion that metals of low work function (high in the electromotive series) would not thrombose on implantation into the aorta or vena cava when used as a prosthetic vessel replacement.

Compliance Effect on Patency of Small Diameter Vascular Grafts
ASAIO Transactions, 1989The compliance mismatch hypothesis as a cause of failure of small diameter grafts was investigated using 4 mm internal diameter, 5 cm long Biolized polyurethane grafts. The luminal surface of 0.5 mm thick Biomer sponge grafts was covered with 100 microns of crosslinked gelatin.

Optimizing Vascular Patency in Replantation
2014Once the decision is made to proceed with replantation of an amputated part, the most critical factor in the short-term success of the replantation is vascular patency. Replantation success rates are approximately 75–80 %, while free tissue transfer enjoys a survival rate which has improved in recent years, with most large series demonstrating success ...

Compliance as a factor effecting the patency of a copolyurethane vascular graft
Journal of Biomedical Materials Research, 1978AbstractA new solid‐wall vascular graft which has a compliance approximating that of the natural artery has been prepared from a copolyether–urethane material. Six of nine of these compliant grafts implanted in dogs were patent on removal, the longest implant time being 77 days for a 4‐mm I.D. femoral artery graft.

Factors Influencing Postoperative Vascular Patency
Neurosurgery, 1976In summary, we have briefly examined the pathogenesis of arterial thrombosis, the importance of vessel wall injury and alteration of blood flow in this process, and finally the rationale for use of various agents in an attempt to promote postoperative vascular patency.

Promotion of Vascular Patency in Dermal Burns with Ibuprofen
The American Journal of Medicine, 1984Differences in the vascular response to burn and freeze injuries were investigated as a model for defining the mechanism and cause of vascular occlusion in rats after dermal burns. Concentrations of thromboxane and prostacyclin in wound fluid were elevated in both types of trauma. However, inhibition of prostaglandin synthesis by indomethacin failed to

Antiplatelet Therapy and Vascular-Access Patency
New England Journal of Medicine, 2009Current predictions estimate that by the year 2020, more than 750,000 people in the United States alone will have end-stage renal disease and over 500,000 will require hemodialysis.1 The success of hemodialysis depends on a well-functioning vascular access, which may be considered the patient's lifeline.

Vascular sounds as an indicator of hemodialysis access patency
The Journal of the Acoustical Society of America, 2005Background: Vascular access for renal dialysis is a lifeline for about 200<th>000 individuals in North America. Stethoscope auscultation of vascular sounds has some utility in the assessment of access patency, yet may be highly skill dependent.
