Extensive stretching of intracranial aneurysm coil causing TIAs
A 58-year-old man with a history of ruptured posterior cerebral artery aneurysm, repaired with coil embolization 5 years previously, presented with right hemi-numbness lasting 30 minutes. Cerebral MRI did not reveal acute stroke. CT angiogram showed a stretched wire complex extending through the posterior communicating artery, down the carotid artery, and into the most inferior visualized portion of descending aorta, terminating in a loosely coiled wire (figure, A and B). A transesophageal echocardiogram showed evidence of a possible thrombus on the coil in the aortic arch (figure, C and D; video on the Neurology® Web ...

Extensive Proximal Migration of Posterior Communicating Artery Aneurysm Coil Presenting with a Transient Ischemic Attack (P5.127)
CONCLUSIONS: Stretched coils and retrained fragments are a rare complication of coil embolization. If retained fragments are present, patients should be maintained on lifelong antiplatelet agents, as embolic events can occur even years after the initial coiling, as illustrated by this case.Disclosure: Dr. Itrat has nothing to disclose.
