Objectives:
To identify and evaluate the cerebral aneurysm remnants after clipping and the endovascular treatment in our institution.
Methods And Materials:
We made a clinical ambispective collection of all aneurysms microsurgically clipped during four years and we analyzed their endovascular treatment.
Results:
There were 290 cerebral aneurysms; in 270 a digital subtraction angiography was made. Ten aneurysm remnants were found (3.7%); of these, a second operation was performed on two, and coil placement was done in six patients.
Conclusion:
The cerebral aneurysm remnants after clipping in our institution are equivalent to international results. The endovascular treatment of this aneurysm is safe and effective.
