As noted in Section 12.5.1, a family of polyaxial copolyesters described in Chapter 2 can be used to prepare two or more of the critical components of a femoral sealing device. Other compliant members of this family of polymers, which can be converted to compliant, stretchable membranes and strong, stretchable monofilament fibers, can be used to construct a mantle or cover for metallic endovascular stents. Thus, a composite of thin film, reinforced with a monofilament in cross-coiled configuration, can be assembled into a highly compliant, expandable, tubular mantle or sleeve. This can be placed tightly as a cover outside an expandable metallic or polymeric stent so that under concentric irreversible expansion at the desired site of... 

Fig. 5.41. a Broad based basilar tip aneurysm. b,c Endovascular treatment was performed with a stent and platinum coils. The stent was deployed with the distal end in the PI segment left and the proximal end in the mid basilar artery (markers). Coiling was done through the mesh of the stent, d 10 month follow-up still showed complete aneurysm occlusion with remodelling of the basilar tip... 

The idea of using an intravascular stent followed by trans-stent placement of coils is a treatment option in patients with a wide-necked aneurysm in which direct surgical dipping or conventional endovascular therapy would be difficult or impossible, and in whom parent artery ocdusion is not a viable option (Byrne et al. 2000 Lanzino et al. 1999b Horowitz et al. 2001 Lownie et al. 2000 Lylyk et al. 2001).

If the external carotid artery territory is affected, sacrifice of the traumatized arterial segment is best performed with glue in our experience. N-butyl 2-cyanoacrylate (NBCA) is gently deposited proxi-mally to the arterial tear or at the level of the stump of the traumatized artery after superselective microcatheterization. Traumatic rupture of the internal carotid artery is usually treated by sacrifice with balloons and coils [7]. The recent availability of covered stents offers another endovascular alternative, especially when occlusion of the internal carotid artery is poorly tolerated [4],...
