Coiling as Retreatment in Intracranial Aneurysm of de novo Formation or Regrowth: Case Report
The patient was a 61-year-old female who underwent clipping 17 years ago because of ruptured right MCA (M1) aneurysm. The aneurysm was found by CT angiography during health screening. CT images identified the aneurysm 17 years ago could not be obtained. The patient had a saccular aneurysm, 3.2 mm in size, with regrowth from the aneurysm dome. The aneurysm regrowth was treated by coiling using single microcatheter technique. One microcatheter (Echelon-10) was introduced into MCA aneurysm. Five coils were required for the aneurysm (total 12 centimeters), indicating near total occlusion. There was no difficulty in coiling the aneurysm through clip shadow. The patient was discharged with 0 of mRS.
