ABSTRACT
INTRODUCTION:
Hemorrhage from a recurrent aneurysm is a major concern after coiling for intracranial aneurysms. We aimed to identify aneurysm recurrence patterns associated with hemorrhage. MATERIAL ANDMETHODS:
We investigated radiological data of patients who underwent coiling for intracranial aneurysms in 2008-2016 and were followed-up for at least 6 months. Aneurysm recurrence patterns were classified as type â , enlargement of aneurysm neck; type â ¡, recurrent cavity within the coil mass; type â ¢, recurrent cavity along the aneurysm wall; and type â £, formation of a daughter sac. We evaluated the incidence of various recurrence patterns with or without hemorrhage.RESULTS:
Of the 173 aneurysms included in the study (mean follow-up period, 32 months; range, 6-99 months), 22 (13%) recurred and required re-treatment. The recurrence patterns included type â , â ¡, â ¢, and â £ in 7 (4%), 4 (2%), 9 (5%), and 2 (1%) cases, respectively. Most of the type â , â ¡, and â ¢ recurrences occurred within 1 year, and type â £ occurred at 7 years after coiling. Three aneurysms exhibited hemorrhage, one with type â ¢ and two with type â £ pattern. The two aneurysms with type â £ recurrence initially occurred as type â ; however, the recurrent neck enlarged gradually, resulting in new sac formation.CONCLUSIONS:
We recommend prompt re-treatment for aneurysms recurring with type â ¢ or â £ patterns, as such patterns were associated with hemorrhage. Furthermore, we need a special care to type â recurrence with enlargement of recurrent neck because this specific pattern may develop to type â £.
