Coiling as Retreatment in Intracranial Aneurysm of de novo Formation or Regrowth: Case Report
The patient was a 47-year-old female who underwent clipping because of right MCA bifurcation aneurysm ruptured 14 years ago. She visited our hospital with recurrent subarachnoid hemorrhage (SAH). On visiting, her mRS was 1 and Hunt and Hess grade was 2. Images of diagnostic studies identified the aneurysm 14 years ago could not be obtained. The patient had a saccular aneurysm, 4.8 mm in size, with regrowth from the aneurysm neck. The aneurysm regrowth was treated by coiling using single microcatheter technique. One microcatheter (Echelon-10) was introduced into MCA aneurysm. Three coils were required for the aneurysm (total 13 centimeters), indicating near total occlusion. There was no difficulty in coiling the aneurysm through clip shadow. The patient was discharged with 0 of mRS.
