A new nonbiologic photopolymerizable glue, polyethyleneglycol 400 diacrylate, was studied with respect to its mechanical and biochemical interaction with human blood vessels. Using the human placental artery model, we tested the ability of polyethyleneglycol 400 diacrylate to prevent leakage of blood at the site of vascular anastomoses, which are made porous by the presence of tissue gaps and suture puncture sites. Fibrin glue is known to augment local vessel thrombogenicity through the presence of the coagulation enzyme thrombin. We tested the effect of externally applied polyethyleneglycol 400 diacrylate (which does not contain thrombin) on luminal thrombin activity and platelet deposition from flowing human blood. At a shear rate of 312 per second and a transmural pressure of 80 cm H2O, the leakage rate of saline from human placental artery anastomoses was 1.0 +/- 1.2 ml/min (n = 8). When the same anastomoses were then glued, 7 of 8 of the anastomoses leaked less than 0.05 ml/min (p < 0.05). Platelet deposition to human vessels was not influenced by the external application of polyethyleneglycol 400 diacrylate either on intact vessels (no polyethyleneglycol 400 diacrylate, 0.51 +/- 0.28 x 10(6) platelets/cm2; with polyethyleneglycol 400 diacrylate, 0.47 +/- 0.26 x 10(6) platelets/cm2; n = 7) or at anastomoses (no polyethyleneglycol 400 diacrylate, 0.69 +/- 0.36 x 10(6) platelets/cm2; with polyethyleneglycol 400 diacrylate, 0.53 +/- 0.33 x 10(6) platelets/cm2; n = 8), p > 0.05.(ABSTRACT TRUNCATED AT 250 WORDS)
