Abstract Aneurysm rest occurs in 1 to 10% of operated patients and of these, 21.8% are due to slipped clips. D´Angelo and coworker (1998) found 1 to 10% of residual aneurysms. They suggest that if the residual aneurysm has less than 2 mm, angiographic control must be performed after 3-5 years of the surgical procedure; if between 2 and 4 mm, the angiographic control must be done in the first 6 months after surgery and then, anually. If it has more than 4mm a direct surgical approach is advised. We present the cases of two female patients submitted to microsurgical treatment of intracranial aneurysm, without any intra-operative abnormal event. The angiographic study further made showed displacement of the clip from its original position and aneurysm again. A review of the literature is also presented.

A incidência de clipagem de aneurismas em que permanecem restos da dilatação varia, nas séries estudadas, de 1-10%. Deste percentual, 21,8% é devido à migração do clipe.D´Angelo e seus colaboradores (1998), encontraram 1 a 10% de aneurismas residuais. Sugerem que quando o resíduo for menor que 2 mm seja realizado estudo angiográfico entre 3-5 anos após o procedimento cirúrgico; se entre 2 e 4 mm, este estudo deve ser mais precoce, dentro dos primeiros 6 meses e depois anualmente; e, quando maior que 4 mm, a reabordagem. Apresentamos os casos de duas pacientes submetidas a tratamento cirúrgico de aneurismas intracranianos, com intra-operatório sem intercorrências e que, em exames ulteriores, evidenciaram migração do clipe de sua posição original. É apresentada, ainda, revisão da literatura.
