Coiling as Retreatment in Intracranial Aneurysm of de novo Formation or Regrowth: Case Report
The patient was a 66-year-old female who underwent clipping because of right P-com aneurysm ruptured 13 years ago. Last year, the patient underwent ventricular-peritoneal shunt and treated due to cerebral infarction. She visited our hospital with recurrent SAH. She had aneurysm regrowth, and her modified Fisher Scale and Hunt and Hess grade were 4, respectively. Consciousness level on admission was stupor. There was saccular wide neck aneurysm, 8 mm in size. Images of diagnostic studies identified the aneurysm 13 years ago could not be obtained. Coiling with double microcatheter technique was performed for the patient. Two microcatheters (Echelon-10) were introduced into the aneurysm. 15 coils were used for the aneurysm (total 116 centimeters), indicating near total occlusion. There was no difficulty in coiling the aneurysm through clip shadow. Her mRS was 1 before the aneurysm rupture and was 4 when she was discharged.
