Perforation of intracranial aneurysms during endovascular treatment with platinum micro-coils is a well-known and serious complication reported to occur in 2–4% of patients.
Inflation of a remodelling balloon across the aneurysm neck or within the proximal parent vessel is an additional technique that theoretically might be useful to reduce flow within the aneurysm and achieve hemostasis.
In the case reports that follow, we present our experience using this technique for managing intraprocedural aneurysm rupture.
