Abstract:
It is difficult to treat the internal carotid arterial (ICA) wall disease between C2 to C7 segment ( the definition of ICA by E. Bouthillier,1996) with present interventional radiological measurements , includling pseudoaneurysm, giant or wide neck aneurysm and complicated carotid cavernous fistula. Some literatures have reported a few cases treated with coronary covered stent (e.g. Jomed coronary stent, Symbiot coronary stent), with favorable results . However, these kinds of coronary covered stents are too rigid, with uneasinees to pass through in tortuous ICA, and often resulting in injury of vascular wall. The utility of covered stent in intracranial artery also caused controversies of exclusion of origins of arterial branches. We analyzed the functional anatomy of ICA and reviewed our experimental results and primarily clinical application on professional intracranial covered stent with special designed structure and delivery system for ICA, in order to explore the possibility of utility of covered stent in intracranial arteries.
