Endovascular Treatment of Recurrent Coiled Aneurysms: Assessment of Complications and Rebleeding during a Decade in a Single Center

摘要: Recurrence is the main drawback of aneurysmal coiling. Additional coiling must sometimes be considered in patients with reopened aneurysms and expose patient to risk a new procedure. Our purpose was assess procedural complications additional endovascular treatments previously coiled but recurrent treated by two neurointerventionalists during decade single center. Between 1999 2009, 637 intracranial were had clinical angiographic follow-up at our institution. Following first embolization, 44 retreated coils 11 second time. Retreatment decided when recurrence showed follow-up. Early retreatments, performed month after an incomplete or failed initial coiling, excluded. We retrospectively analysed complications, rebleeding, outcomes retreatments. No death bleeding occurred these 55 procedures. We three periprocedural thromboembolic permanent morbidity 1.8%. Clinical follow-ups ranged from six months nine years (mean: 37 months, median: 36 months). Thirty-seven (84%) stable occlusion Seven not due stability packing. rebleeding observed period. results show that treatment associated low risk.
