Aneurysm
This document summarizes techniques for treating aneurysms, including: - Endovascular techniques like coiling, remodeling, stent-assisted coiling, Onyx, and graft stents have become prevalent since FDA approval of GDC coils in 1995. - The ISAT trial from 2002-2005 compared coiling to clipping for ruptured aneurysms and found coiling had a 7.4% lower risk of death or dependency. - Newer techniques like flow diverters which have dense stent structures are used to prevent blood flow into the aneurysm sac but cost around 10,000 Euros. Detection and treatment of vasospasm beyond traditional measures is also discussed.

Editor's Notes
- #34 A case of NPC s/p radiotherapy, one month ago, he had naso-oral bleeding from branch of right ECA. NBCA embolization of the branch stopped bleeding. This time, he had massive naso-oral bleeding again. Angio showed right ICA cervical segment pseudoaneurysm. Massive bleeding from aneurysm occurred during study. Use Abbot Jostent *2 to cover the location of pseudoaneurysm.

- #36 A case of traumatic CCF s/p balloon embolization but failed. Use Jostent to cover the fistula successfully.
- #37 A case of traumatic CCF s/p balloon embolization but failed. Use Jostent to cover the fistula successfully.
- #43 MCA aneurysm with M1 vasospasm. Coiling was done but vasospasm more severe.
- #44 After coiling, use BS Sentry balloon to angioplasty the M1 segment. Distal artery treated with Papaverine and Nimodipine.
