“…3 In all cases, the coils remained stable just as described in most coil migration cases. 6 This event confirms that stable coils may change position and migrate, as it happened in a reported case that describes the emergence of late symptoms despite a successful embolization performed 8 days before. 7 The time between the initial procedure and detection of the migration varies from days to months.…”

“…Severe neurological consequences have been described in other reports. 4,6,7 One case demonstrated that coil migration represents a rare but potentially severe complication of cerebral aneurysm embolization. A man with subarachnoid hemorrhage had a delayed (8 days after the procedure) migration of a coil loop after adjunctive balloon remodeling of an anterior communicating artery (AComA) aneurysm causing ischemia on the anterior cerebral artery and paresia of the lower extremity.…”

“…The patient opted for surgical treatment. 6 A retrospective study with 346 cases of cerebral aneurysms embolized from 1997 to 2001 had 5 complications related to GDCs. Two patients with AComA and middle cerebral artery (MCA) aneurysms had GDCs migration to segments A2 and M2, respectively.…”

Background Coil migration after cerebral aneurysm embolization is a very rare complication. It can take place early or late in the postoperative period, evolving asymptomatic and causing severe neurological deficits. Ruptured aneurysms of anterior communicant artery were the most frequent reported examples in the literature. Case Report We report three cases of patients with unruptured aneurysms treated with coils and remodeling balloon technique. The first case was that of a left posterior communicating artery aneurysm with coil migration to a distal cortical branch of ipsilateral middle cerebral artery (MCA). The patient had mild paresthesia in the arm for a few days. The second one was a fenestrated basilar artery aneurysm with coil migration to the P2 segment of the left posterior cerebral artery. The patient was fully asymptomatic. The third case was a MCA aneurysm with coil migration to the M3 segment. There were no ischemic complications, and all patients underwent a new endovascular procedure. Conclusions Coil migration is a rare but not always severe complication. Antiplatelet agents are recommended even if the coil migration is asymptomatic.

“…In 10.3% of coil‐treated aneurysms, recanalization necessitates retreatment . Other issues include possible coil migration from the aneurysm sac into the parent artery, and a risk of intraprocedural aneurysmal rupture, which can have devastating consequences. Given this potential for procedural complication and suboptimal long‐term healing, it is desirable to develop new technologies to enhance aneurysm treatment outcomes.…”

The endovascular delivery of platinum alloy bare metal coils has been widely adapted to treat intracranial aneurysms. Despite the widespread clinical use of this technique, numerous suboptimal outcomes are possible. These may include chronic inflammation, low volume filling, coil compaction, and recanalization, all of which can lead to aneurysm recurrence, need for retreatment, and/or potential rupture. This study evaluates a treatment alternative in which polyurethane shape memory polymer (SMP) foam is used as an embolic aneurysm filler. The performance of this treatment method was compared to that of bare metal coils in a head-to-head in vivo study utilizing a porcine vein pouch aneurysm model. After 90 and 180 days post-treatment, gross and histological observations were used to assess aneurysm healing. At 90 days, the foam-treated aneurysms were at an advanced stage of healing compared to the coil-treated aneurysms and showed no signs of chronic inflammation. At 180 days, the foam-treated aneurysms exhibited an 89-93% reduction in cross-sectional area; whereas coiled aneurysms displayed an 18-34% area reduction. The superior healing in the foam-treated aneurysms at earlier stages suggests that SMP foam may be a viable alternative to current treatment methods. © 2016 Wiley Periodicals, Inc.

“…Factors thought to increase the risk of coil migration include (a) coil related factors such as instability of the coil within the aneurysm, over-or under-packing of the coil, and type of coil, and (b) aneurysmal factors such as size, shape, and neck width relative to the fundus, the wall shear stress, and vortical flow within the aneurysm [3,5]. Dehydration, vasospasm, and the prothrombotic nature of SAH all increase the risk of distal occlusion after coil migration [3].…”
