BackgroundIntracranial vascular malformations are increasingly being treated via the endovascular route. Though generally safe, a multitude of intraprocedural complications that potentially lead to disastrous clinical outcomes may arise. It is crucial for the operators to be well versed with the various techniques that are available to overcome any procedure-specific complications.MethodsWe present 2 cases in which we encountered premature intravascular detachment of the microcatheter tip and coil migration while treating a dural arteriovenous fistula and aneurysm, respectively. We used a stentriever to remove the detached microcatheter tip and suction using the reperfusion catheter to remove the migrated coil, both techniques that have not been reported in the literature thus far.ResultsDetached microcatheter tip and migrated coil were successfully retrieved using a stentriever and aspiration catheter.ConclusionsThese novel techniques could potentially reduce mortality and morbidity associated with neurointervention.Copyright © 2020 Elsevier Inc.
