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.

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.

Revisiting vascular patency after spleen-preserving laparoscopic distal pancreatectomy with conservation of splenic vessels [PDF]
Surgical Endoscopy and Other Interventional Techniques, 2012 BACKGROUND: We evaluated vascular patency and potential changes in preserved spleens after laparoscopic spleen-preserving distal pancreatectomy (SPDP) with conservation of both splenic vessels.

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.

Vascularization of Melanoma by Mobilization and Remodeling of Preexisting Latent Vessels to Patency
Cancer Research, 2005AbstractTumors must manipulate the host vasculature to provide a blood supply adequate for their proliferation. Although tumors may arise as avascular masses, there is increasing evidence that some tumors begin to proliferate by first co-opting preexisting host blood vessels.

Vascular Medullary Patency in Free Vascularized Bone Grafts: Ct Scan Experimental Study
Journal of Reconstructive Microsurgery, 1988In an experimental study using 13 mongrel adult dogs, 6 cm of the anterior part of the left ninth rib were harvested, including the posterior intercostal vessels. The grafts were transferred, based on the periosteal circulation alone, to a previously induced femoral head ischemic necrosis.

Patency and Durability of Small Diameter Silicone Rubber Vascular Prostheses
Biomaterials, Artificial Cells and Artificial Organs, 1989This study evaluated the long-term patency and durability of 6 mm internal diameter (ID), 18-30 micron pore size replamineform silicone rubber vascular prostheses as canine aortic interposition and arteriovenous (A-V) grafts. Six prostheses (6 mm ID x 8 cm length) were evaluated as aortic grafts for 24 to 30 months, and 10 prostheses (6 mm ID x 8-10 cm
