Rerupture of coil-embolized aneurysm during long-term observation. Case report

J Neurosurg. 1998 Jun;88(6):1096-8. doi: 10.3171/jns.1998.88.6.1096.

Abstract

The authors describe the histopathological findings in a case involving rerupture of a recanalized aneurysm of the internal carotid artery 8 months after partial (95%) embolization with interlocking detachable coils. The aneurysm was filled with poorly organized thrombus, and its orifice was devoid of endothelial cells. It appears likely that a long period of observation may be required to confirm the complete thrombotic organization of coil-embolized aneurysms. This indicates that caution is needed because rupture may follow recanalization of the aneurysm.
