RESUMO
We present the case of an ischemic stroke associated with partially occlusive acute calcified cerebral emboli large vessel occlusion (CCE LVO). No revascularization strategy guidelines have been established for this unique acute ischemic stroke population, although many studies have reported impaired and inconsistent responses to both thrombolysis and thrombectomy. The patient in this case report, unfortunately, experienced a failed attempt at complete thrombolysis, resulting in a poor clinical outcome. Endovascular thrombectomy was not performed because of incomplete obstruction and risk of injury. Follow-up imaging revealed an acute ischemic stroke at the large middle cerebral artery and a new intraparenchymal hemorrhage with complete absence of the previously identified calcified embolus. This case and current literature demonstrate that more data are needed to determine the best revascularization approach for patients with CCE LVO stroke. With tissue plasminogen activator marginally effective in these patients, thrombectomy should be considered in highly unstable, clinically symptomatic patients even only with partial vessel occlusion.
