Background:
Coil embolization is increasingly becoming the surgical intervention of choice for cerebral aneurysms, particularly for those in the posterior circulation. However, in cases where it is difficult to perform coil embolization, microsurgical clipping is still required.
Case Description:
We present a case of a high-positioned, ruptured, recurrent basilar tip aneurysm treated with a combination of microsurgical clipping through the trans-lamina terminalis approach and endovascular procedure. The technical considerations of this approach are discussed.
Conclusion:
Microsurgical clipping through the trans-lamina terminalis approach combined with an endovascular technique can be effective for basilar tip aneurysms. This approach is particularly useful for high-positioned, small, anterior projective aneurysms and cases with dilation of the third ventricle due to hydrocephalus or clot.
