Both stent-assisted coiling (SAC) and flow diversion with the Pipeline Embolization device (PED; Medtronic Inc) have been shown to be safe and clinically effective for treatment of small (<10 mm) unruptured aneurysms. However, the economic impact of these different techniques has not been established. ⋯ With increasing use of PED for treatment of small unruptured anterior circulation aneurysms, our study indicates that PED is cost-effective relative to stent coiling irrespective of aneurysm size. This is due to lower aneurysm recurrence rate, as well as better health outcomes.
