Aspiration Thrombectomy: 2-Dimensional Operative Video

Acute ischemic stroke is one of the leading causes of disability and mortality worldwide. There have been significant improvements to the treatment of acute ischemic stroke over the past 5 yr, specifically related to strokes caused by large vessel occlusions. Stent retrievers with and without local aspiration and direct aspiration alone have all been demonstrated as viable treatment options for this patient population. This case represents the surgical technique for direct aspiration for the treatment of large vessel occlusion. A 76-yr-old man presented with right-sided weakness and aphasia. His last known normal was 5 h ago. His NIHSS (National Institutes of Health Stroke Scale) was 18. The noncontrast computed tomography (CT) did not show a significant infarct burden and ASPECTS (Alberta Stroke Program Early CT Score) of 9. CT angiogram demonstrated a left M1 occlusion. The patient was not a candidate for tissue plasminogen activator (tPA) because of time to presentation; however, the patient was deemed to be a candidate for emergent thrombectomy. Consent was obtained per institutional guidelines for the emergent procedure and the video recording. The video demonstrates a direct aspiration thrombectomy technique for the treatment of stroke. The patient successfully underwent direct aspiration thrombectomy with a TICI 3 (thrombolysis in cerebral infarction) recanalization.
