AneuFill polymer is used in conjunction with AneuFix polymer to fill the complete aneurysm sac around an EVAR endograft in the same procedure as the EVAR endograft is placed.
The AneuFix polymer provides the required radiopacity in critical area's. The AneuFill polymer (no tantalum) is used to fill the complete sac
Filling the sac and fixating the endograft:
· prevents the occurrence of endoleaks
· prevents migration of the endograft, resulting from pulsatile aortic flow
· reduces the incidence of endograft occlusion due to endograft migration.
In prophylactic Sac Filling the thickness of the implant as seen under x-ray will vary, from <2mm in the proximal neck zone, distal seals in the Iliac vessels and lumbar vessels, to >60mm on the maximum diameter of the aneurysm sac.
Low density AneuFill has the same silicone polymer consistancy as AneuFix, but no tantalum.
AneuFill is used in conjunction with high tantalum density AneuFix to prevent scatter under CT.
For prophylactic sac filling higher volumes of polymer are needed: ranging from 50 to 150ml.
Aneufill therefore comes in 60ml syringes. In conjunction with the 24ml AneuFix syringe, for the majority of sac filling cases therefore 1 or 2 AneuFill syringes will be sufficient
