Coiling as Retreatment in Intracranial Aneurysm of de novo Formation or Regrowth: Case Report / 신경중재치료의학

ABSTRACT

Development of de novo aneurysm or aneurysm regrowth after complete clipping of an intracranial aneurysm is rare. We report coiled cases of de novo aneurysm and aneurysm regrowth. We retrospectively reviewed 107 cases of intracranial aneurysm coiling performed in our hospital, identifying five cases of coiled aneurysm that were de novo aneurysm or aneurysm regrowth. In all the cases, total or near total occlusion was seen. There were no complications related to the procedure. In two of the three patients with ruptured aneurysms, consciousness level on admission was stupor. When the patient was discharged after the treatment, one of them had 4 of the modified Rankin Scale. The other one had 5 on discharge. The rest three patients had 0. As for a de novo aneurysm or a regrowth of aneurysm, coiling may be considered when clipping is difficult.
