Официальное название

Outcomes of Mechanical Thrombectomy of Acute Ischemic Stroke Anterior Circulation Distal Vessel Occlusion

Обзор

Ischemic stroke continues to be of the leading causes of disability and death. Distal vessel occlusion one of most presenting and disabling varieties of ischemic stroke. Distal vessel occlusion stroke is a type of ischemic stroke that affects the small arteries in the brain, usually beyond the M2 segment of the middle cerebral artery. These strokes can cause various neurological symptoms depending on the location and size of the occluded vessel and the extent of the brain tissue damage

Подробное описание

DMVOs are defined by the Distal Thrombectomy Summit Group consensus statement as thromboembolic occlusion of the anterior cerebral artery, M2-M4 middle cerebral artery (MCA), posterior cerebral artery (PCA), posterior inferior cerebellar artery, anterior inferior cerebellar artery or superior cerebellar artery. It is estimated that 25-40% of all AIS is due to DMVO.Though distal vessel occlusion associated with poor disabling comorbidities'.With different aetiology weather primary Embolic from (heart, carotid or aorta),thrombotic (atherosclerotic, hypertension or Diabetes ,smoking \&hyperlipidaemia) or Secondary distal vessel occlusion that occurs as a complication of a proximal large vessel occlusion, either spontaneously or after treatment with intravenous thrombolysis or endovascular thrombectomy. This can be due to thrombus fragmentation and migration or incomplete reperfusion of the affected vascular territory . Endovascular thrombectomy is well established as a highly effective treatment for acute ischemic stroke (AIS) due to proximal, large vessel occlusions (PLVOs). Recent advances in stent retriever and aspiration catheter technology are more promising results to reach more distal vessels, with a good outcome. However, MT in M2 emerging with different technique using stent Retriever or aspiration or both nowadays, evidence of other MT in distal vessel occlusion is poor.
