Prostaglandin content of tissue lining vascular prostheses
This laboratory previously demonstrated arterial regeneration with a confluent endothelial-like flow surface 3-4 weeks after interposition of absorbable prostheses but not of dacron prostheses into the rabbit aorta. This study evaluates prostaglandin contents of inner capsular tissues within arterial prostheses. 6-keto-PGF/sub 1..cap alpha../ and TxB/sub 2/ were assayed (/sup 3/H-RIA) in supernatants of sonicated homogenates of tissues on the inner aspect of (a) absorbable polydioxanone (PDS), (b) absorbable polyglactin 910 (PG910), or (c) compound dacron-PG910 prostheses 3 or 6 months following implantation into rabbit aortas. Normal aortic controls from each rabbit were similarly treated. The 6-keto-PGF/sub 1..cap alpha../ values for all groups were lower than normal controls (p < .05). The ratio 6-keto-PGF/sub 1..cap alpha..//TxB/sub 2/ for PDS was nearly identical to normal aorta (1.69 +/- .54). This study shows that the quantity and ratio of eicosanoids in the inner capsular tissues is modified by the composition of the implanted arterial prosthesis.
