[Slipped clip: report of two cases].
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.
