aspiration thrombectomy
Mechanical clot removal technique using suction through a large-bore catheter to extract thrombus from cerebral or peripheral vessels.
Full Definition
Aspiration thrombectomy is a minimally invasive endovascular technique for removing blood clots using direct aspiration through specialized catheters. The procedure involves advancing a large-bore aspiration catheter to the clot location and applying continuous suction to extract the thrombus material. This approach is commonly used as first-line therapy for acute stroke intervention and can be performed alone or in combination with stent retriever devices. The technique offers advantages including shorter procedure times and reduced risk of clot fragmentation compared to mechanical retrieval alone.
Usage
Usage note: Often abbreviated as ADAPT (A Direct Aspiration first Pass Technique) in clinical literature.
