Accentuated Vasospasm during Treatment of an Acutely Ruptured Aneurysm with Electrolytically Detachable Coils: Coincidence or Causation?
We report an unusual case of precipitous worsening of vasospasm associated with subarachnoid haemorrhage that developed during endosaccular coil embolisation of a ruptured posterior communicating aneurysm. The acutely worsening vasospasm occurred in the distal ipsilateral anterior circulation remote from the site of microcatheter manipulation, resulting in transient occlusion. Despite successful endovascular treatment of both the aneurysm and vasospasm, the patient continued to clinically decline and eventually died. This case raises important issues regarding the potential mechanisms and optimal therapeutic strategies for this complication, which are reviewed.
