Introduction Vast majority of unruptured intracranial aneurysms (UIA) do not show symptoms, with only around 10% becoming apparent before rupture, displaying signs of compression effects secondary to large or growing aneurysms which leads to urgent treatment.

Aim of Study Our study aims to highlight the role of FDS placement among low- to- middle income countries with limited access to such intervention in a setting of rising number of symptomatic UIA

Methods We report a case of 59-year-old male with UIA presenting as bitemporal hemianopsia who was treated with flow-diverter stent and partial coil embolization. We did a systematic review of patients with ICA aneurysms presenting with neuro-ophthalmologic symptoms treated with flow diverter stents and discussed the clinical features and outcomes.

Results A total of 856 patients who had UIA were treated with different flow diverter devices. In study of Griessenauer et al, 10% of patients experienced prompt improvement in visual function and in the meta- analysis of Kaiser et al, a complete recovery from their initial impairment was observed in 48% of the patients, while nearly 75% displayed improvement in symptoms related to compression. Most common morbidity encountered across studies were related to hemorrhagic and ischemic complications which accounts for 3.7% in one study.

Conclusion FDS offer an additional advantage by reducing the mass effect of the aneurysm sac. Early detection and treatment increases the likelihood of symptom improvement, hence prioritization of this is crucial in a setting such as here in the Philippines wherein limited facility are capable for these endovascular interventions.
