Delayed symptomatic thromboembolism after unruptured middle cerebral artery aneurysm embolization.

Endovascular treatment has been increasingly performed for unruptured intracerebral aneurysms. However, thromboembolic complications, which develop mostly within 48 hours after the procedure, are the most common and major complications of endovascular treatment. We present a rare case of delayed symptomatic thromboembolism in an ischemic stroke patient who had undergone coil embolization for unruptured middle cerebral artery (MCA) aneurysm.
