Coiling as Retreatment in Intracranial Aneurysm of de novo Formation or Regrowth: Case Report
The patient was a 46-year-old male who underwent clipping 17 years ago because of ruptured basilar top aneurysm. The aneurysm was found by Computed Tomography (CT) angiography during health screening. CT images identified the aneurysm 17 years ago could not be obtained. The patient had a wide neck aneurysm, 7.8 mm in size, with regrowth from the aneurysm neck. The aneurysm regrowth was treated by coiling using double microcatheter technique. Two microcatheters (Echelon-10, EV3, Irvine, CA, USA) were introduced into the basilar top aneurysm through both vertebral arteries. Ten coils were used for the aneurysm out of 11 coils (total 40 centimeters), resulting near total occlusion. There was no difficulty in coiling the aneurysm through clip shadow. The patient was discharged with 0 of mRS.
