====== Bilateral aneurysm ======

Sweid et al., from the [[Thomas Jefferson University Hospital]] analyzed the clinical and angiographic outcomes of 16 individuals with [[bilateral aneurysm]]s who were treated with a two-stage [[flow diversion]] treatment at a [[tertiary]] [[referral center]] between January 2010 and July 2018.

One patient had two [[aneurysm]]s treated with a single [[flow diverter]] (FD) on the contralateral side. The aneurysms treated were either [[ophthalmic artery aneurysm]], [[superior hypophyseal artery aneurysm]], [[posterior communicating artery aneurysm]], or [[cavernous carotid aneurysm]]s with an average size of 6.5 mm. There were no major [[complication]]s such as [[in-stent stenosis]], [[thromboembolic event]]s, distal intra-parenchymal hemorrhage, re-rupture, stent migration, or neurological death. All patients had good functional outcomes. At 24 months follow-up, 81% of aneurysms showed complete occlusion of all treated aneurysms. No aneurysm required re-treatment.

This study demonstrates that a two-stage flow diversion treatment of bilateral aneurysms is both safe and efficacious. Timing of the contralateral flow diverter stent is critical. They found that 6 months allows for adequate neurological recovery and stent [[endothelialization]]
