Treatment of acute aneurysmal subarachnoid haemorrhage with primary flow diversion: 5-year single-centre experience

Highlights: • FDS are not considered first line in SAH due to bleeding and thrombotic risks. • FDS can have a role in acute subarachnoid if conventional techniques not feasible. • Indirect treatment, with FDS not crossing aneurysm neck, should be avoided. • FDS in acutely ruptured complex aneurysms demonstrate a satisfactory safety profile. To evaluate the safety and efficacy of treatment of patients presenting with acute aneurysmal subarachnoid haemorrhage (SAH) with primary flow-diverting stents (FDS; with or without adjuncts), with comparison to the published literature.
