Challenges of Large Vessel Vasculitis Stroke Patient with Complicated Endovascular Thrombectomy: A Case Report

The causes of acute stroke in patients with SLE are multifactorial. Antiphospholipid-associated hypercoagulability and inflammation-induced platelet activation are major causes of ischemic stroke in SLE patients. As such patients underwent intravenous thrombolysis and endovascular thrombectomy, they may have higher risk of complications and less favorable outcome.

A 30-year-old woman with underline SLE and Takayasu arteritis who presented with right CCA and MCA occlusion status post rtPA and endovascular thrombectomy. Twelve hours after the procedure, head CT was ordered due to anisocoria with loss of pupillary light reflex. The head CT showed partial obliteration of suprasellar and quadrigeminal cistern due to extensive brain edema, leading to her decompressive craniectomy. Two days later, patient's both pupil became dilated with head CT showing occlusion of the left MCA. Her condition drastically went downhill when complications such as central DI and myocardial stunning occurred.

Although autoimmune vasculitis is not listed as an absolute contraindication to endovascular thrombectomy, given the antecedent reports, it is prudent to disclose possible complications to both the patient and family while making the decision.
