Characteristic
Percent of grafts with time to
hemostasis
There were a significantly higher number of Vectra group patients who had early use of
the graft, than in the ePTFE group (Table 3). After cannulation, there were more patients
in the Vectra group that had hemostasis times
enhanced when the time to hemostasis was
primary and functional patencies were similar in both Vectra and ePTFE groups.
Operative Techniques
Opening the Package
Holding the outer tray, peel back the lid and remove the inner tray. Peel back the inner
tray lid and carefully remove the graft using sterile atraumatic instruments or gloves.
Hydrating the Graft
Prior to implantation, hydrate or soak the graft in a sterile solution of normal physio-
logic saline. (Figure 3) While it is soaking, gently compress the submerged graft to dis-
place the air from the voids in the microporous structure. When the bubbles stop, the
air has been displaced and you may proceed with graft placement.
