As reported through the article titled, "how to web: a practical review of methodology for the use of the woven endobridge", a patient with an incidental basilar apex aneurysm presented for elective web treatment.Immediate postdeployment digital subtraction angiogram (dsa) demonstrated adequate deployment of the web within the aneurysm.During the six- month follow- up, the dsa showed web compression and neck remnant.Two- year follow- up dsa showed growing neck remnant.The decision was made to proceed with stent-assisted coiling of the neck remnant.Immediate post- retreatment native dsa demonstrated a coil mass within the neck remnant and stent spanning from the left posterior cerebral artery into the basilar artery.
