Hemodynamic Characteristics Associated With Paraclinoid Aneurysm Recurrence in Patients After Embolization
Conclusions: High peak systolic WSS, OSI and velocity around aneurysm neck areas after embolization of paraclinoidal aneurysms may be important factors leading to recurrence. Introduction Paraclinoid aneurysms are defined as aneurysms arising from the segment of the internal carotid artery (ICA) between the distal dural ring and the origin of the posterior communicating artery. They account for approximately 1.3–5% of all intracranial aneurysms and they comprise the majority of such aneurysms in females (1–3). Hemodynamic characteristics are thought to be the most important risk factors for occurrence...

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 ...

Recurrent posterior circulation infarction caused by anomalous occipital bony process in a young patient
Conclusion: Arterial thromboembolism originating from the left vertebral artery compressed by the anomalous occipital bony process is a rare but not to be overlooked cause of posterior circulation infarction. When intractable to medical treatment, endovascular occlusion of the vertebral artery without flow disturbance to the posterior circulation may be a useful treatment option when surgical removal is not feasible.

Endovascular and Surgical Treatment of Unruptured MCA Aneurysms: Meta-Analysis and Review of the Literature.
Conclusions. This review weakly supports clipping as the preferred treatment of unruptured MCA aneurysms. Clinical outcomes did not differ significantly between the two groups. PMID: 24800103 [PubMed]

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.
