Thrombectomy
surgical removal of a blood clot from a blood vessel
Mechanical thrombectomy, or simply thrombectomy, is the removal of a blood clot (thrombus) from a blood vessel, often and especially endovascularly as an interventional radiology procedure called endovascular thrombectomy. It contrasts with thrombolysis (clot dissolution) by thrombolytic medications (e.g., alteplase, reteplase), as either an alternative or complement.
Thrombectomy is commonly performed in the cerebral arteries as treatment to reverse the ischemia in some ischemic strokes (i.e., those in which the blockage is a suitable candidate for such retrieval). Open vascular surgery versions of thrombectomy also exist. The effectiveness of thrombectomy for strokes was confirmed in clinical research conducted in 2015.
Applications in brain
Mechanical thrombectomy can be used to remove blood clots from the brain. An interventional neuroradiology procedure uses an aspiration catheter inserted through the groin to apply a retriever, or, in some cases, suction, to capture and remove the clot.
Mechanical thrombectomy can be used within 24 hours after the stroke has occurred. It is the standard of care for large vessel occlusions, with studies showing a significant increase in functionality compared to medication without intervention.
History
Early endovascular treatments (Intra-arterial thrombolysis) released of clot-dissolving pro-urokinase through a catheter in proximity to the clot.
“Thrombectomy” enters the record as surgical removal of a blood clot from a blood vessel. Crown Archives preserves that source wording while asking what Thrombectomy, surgical and removal can confirm, complicate or overturn.
Why this record matters
“Thrombectomy” is worth following because a concise public description often conceals a longer documentary argument. Here, Thrombectomy, surgical and removal provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q2429588. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
