Cerebral Artery Aneurysm

More than half a decade of experience and follow-up has now been accumulated with regard to flow diversion as a treatment for intracranial aneurysms; however, many uncertainties, such as the nature of aneurysmal remnants and the meaning of non-regressed, non-perfused aneurysmal masses, are still unknown. Here we discuss a 22-year-old man who presented with a grade 1 subarachnoid hemorrhage secondary to a dissecting right anterior cerebral artery aneurysm who was subsequently treated with a Pipeline Embolization Device construct. After ceasing dual antiplatelet therapy himself, he was found on MRI to have an area of increased aneurysmal remnant reperfusion. This was found to connect to multiple channels which reconstituted flow within the distal construct on angiography. The central area of construct thrombosis could not be visualized on MRI. The finding suggests that non-opacified aneurysmal remnants that have not regressed are biologically active and raises concerns regarding using MRI for long term follow-up.

Flow Diverters

BackgroundThe off-label use of flow diverters in the treatment of distal aneurysms continues to be debated.ObjectiveTo report our multicenter experience in the treatment of complex anterior cerebral artery aneurysms with the Pipeline embolization device (PED).MethodsThe neurointerventional databases of the four participating institutions were retrospectively reviewed for aneurysms treated with PED between October 2011 and January of 2016. All patients treated for anterior cerebral artery aneurysms were included in the analysis. Clinical presentation, location, type, vessel size, procedural complications, clinical and imaging follow-up were included in the analysis.ResultsTwenty patients (13 female) with 20 aneurysms met the inclusion criteria in our study. Fifteen aneurysms were classified as saccular and five as fusiform (mean size 7.3 mm). Thirteen aneurysms were located in the anterior communicating region (ACOM or A1/2 junction), six were A2-pericallosal, and one was located in the A1 segment. Six patients had presented previously with subarachnoid hemorrhage and had their aneurysms initially clipped or coiled. There was one minor event (a small caudate infarct) and one major event (intraparenchymal hemorrhage). Sixteen of the 20 patients had angiographic follow-up (mean 10 months). Eleven aneurysms were completely occluded, one had residual neck, and four had residual aneurysm filling.ConclusionsThe treatment of complex anterior cerebral artery aneurysms with the PED as an alternative for patients who are not good candidates for conventional methods is technically feasible and safe. Mid-term results are promising but larger series with long-term follow-up are required to assess its effectiveness.

Long Term Follow Up

The efficacy of a short leg walking cast in the treatment of chronic plantar heel pain was assessed for 32 patients with 37 involved extremities treated over a 2-year period. All patients had failed numerous other treatment modalities and had been symptomatic for an average of 1 year. Long-term follow-up for 24 patients with 28 involved extremities revealed complete resolution of pain for 7 extremities (25%), improvement for 17 (61%), and no improvement for 4 (14%). Ten (42%) patients were completely satisfied with cast treatment, 3 (12%) were satisfied with reservations, and 11 (46%) were dissatisfied. Casting appears to be a reasonable option for patients with recalcitrant heel pain and should be offered before surgical intervention.

Aneurysm Occlusion

Background Flow diversion with the Pipeline embolization device (PED) is a widely accepted treatment modality for aneurysm occlusion. Previous reports have shown no recanalization of aneurysms on long-term follow-up once total occlusion has been achieved. Case description We report on a 63-year-old male who had a large internal carotid artery cavernous segment aneurysm. Treatment with PED resulted in complete occlusion of the aneurysm. However, follow-up angiography at four years revealed recurrence of the aneurysm due to disconnection of the two PEDs placed in telescoping fashion. Conclusion Herein, we present the clinico-radiological features and discuss the possible mechanisms resulting in the recanalization of aneurysms treated with flow diversion.

Background Insertion of a balloon-expandable stent (BES) in patients with symptomatic intracranial atherosclerosis is a treatment option for reperfusion therapy. In this study, we retrospectively reviewed clinical outcomes during long-term follow-up after insertion of balloon-expandable stents in patients with symptomatic middle cerebral artery (MCA) stenosis. Methods Institutional review board approval was obtained for retrospective review of patient data. Thirty-four patients (15 men, 19 women; median age, 67.5 years) with symptomatic MCA stenosis underwent balloon-expandable stent insertion between June 2008 and December 2010. Patient records were reviewed for angiographic findings and clinical outcomes during long-term follow-up. Results Of these patients, 22 presented with acute ischemic stroke with underlying MCA atherosclerosis and had good clinical outcomes (modified Rankin Scale score (mRS): 0–2) after reperfusion therapy. Indications for stenting for the remaining 12 patients were recurrent transient ischemic attacks (TIAs) refractory to medical therapy and MCA stenosis greater than 70%. During the poststenting follow-up period, which ranged from 61 to 108 months (median, 67.5 months), a TIA occurred in five patients. Of these five patients, one experienced a complete reocclusion of the MCA stent, and three had symptomatic restenosis. The remaining 29 patients did not experience any further ischemic events or restenosis during the follow-up period. Conclusions In our study, treatment with balloon-expandable stents in patients with symptomatic MCA stenosis resulted in low recurrence rates for both ischemic events and restenosis during long-term follow-up.
