“…The only other case of migrated Onyx in the literature [10] described migration of Onyx into a superior vena cava (SVC) stent following embolisation of a dural arteriovenous malformation through the right meningeal artery. The patient developed SVC syndrome and was treated by ''angioplasty of the stent and removal of the Onyx from a common femoral vein approach by interventional radiology''.…”

We report the first case of intervention for a proximal type 1 endoleak following Nellix endovascular aneurysm sealing repair of an aortic aneurysm. This was complicated by migration of Onyx into one of the Nellix graft limbs causing significant stenosis. Subsequent placement of a covered stent to affix the Onyx between the stent and the wall of the Nellix endograft successfully restored stent patency.

“…Wang et al [7] reported unintended Onyx migration into the middle inner ear 6 years following embolization of a right temporal AVM. Crusio et al [8] documented Onyx migration into a right atrium stent 2 weeks after embolization of the right meningeal artery for a dural AVM. Several cases of delayed Onyx migration have also been reported in patients with dural arteriovenous fistulas (DAVFs).…”

Introduction: Brain arteriovenous malformations (AVMs) are increasingly being treated with Onyx liquid embolic agent (Onyx, Medtronic, Inc.). The phenomenon of delayed Onyx migration is not well documented in the literature. Moreover, the clinical presentation associated with Onyx migration is not well understood. Case Presentation: A pediatric patient with a history of neonatal seizures was referred to our institution upon experiencing daily headaches with photophobia, phonophobia, and sleep disturbance. Cerebral angiography revealed an arteriovenous malformation (AVM) of the medial left cerebellar hemisphere. Preoperative embolization with Onyx liquid embolic achieved 25% closure of the AVM nidus. Upon developing worsening headaches the following day, new perinidal parenchymal edema was revealed on MRI, and urgent angiography demonstrated delayed migration of Onyx into the venous drainage. The patient underwent emergency resection of the AVM due to the risk of hemorrhage resulting from venous outflow obstruction. Discussion/Conclusion: Our report and literature review demonstrate that while the delayed, unexpected migration of Onyx embolic material has been alluded to in a handful of papers, this phenomenon is not well documented. Future research is needed to understand the frequency of delayed Onyx migration from brain AVMs and the possible clinical presentations to look for. The sudden development of headaches and other signs of perilesional edema, in particular, should prompt repeat angiographic examination due to the possibility of delayed liquid embolic migration.

BackgroundThe balloon-assisted sinus protection technique has been described as a sinus-preserving technique during transarterial embolization (TAE) of dural arteriovenous fistulas (DAVFs). However, some serious complications of this technique have been documented.ObjectiveTo describe our preliminary experience with a new technique called stent-assisted sinus protection (SSP).MethodsWe performed a retrospective analysis of seven consecutive patients with type I or IIa DAVFs of the lateral sinus treated by TAE with a closed-cell stent temporarily deployed in the sinus.ResultsOf the seven patients, four had type I DAVF, and three had type IIa DAVF. The patency of all involved sinuses and their tributaries (including the inferior anastomotic vein and the superior petrosal sinus) was preserved. At the end of the procedure, all stents were successfully retrieved with embolic particles trapped in their meshes. No procedural complications were noted. Clinical follow-up was satisfactory, with complete resolution or significant reduction of pulsatile tinnitus.ConclusionsSSP appears to be feasible and probably safe. However, larger studies are needed to confirm these preliminary results.
