Mechanical thrombectomy

Mechanical thrombectomy, or simply thrombectomy, is the interventional procedure of removing a blood clot (thrombus) from a blood vessel. It is commonly performed in the cerebral arteries (interventional neuroradiology).

Similar to arterial embolic stroke, devices such as Stentriever or Penumbra may be used for clot extraction. Additionally, devices intended for other sites e.g., clot extraction from dialysis fistula, have also been used in cranial sinuses 1).

The challenge during endovascular intervention is negotiating the sigmoid-transverse sinus junction especially when using bulkier catheters e.g., AngioJet.

Endovascular recanalization therapy (ERT) has been a standard of care for patients with acute ischemic stroke due to large vessel occlusion (LVO) within 6 hours after onset, since five landmark ERT trials conducted by 2015 demonstrated its clinical benefit. Two randomized clinical trials demonstrated that ERT, even in the late time window of up to 16 hours or 24 hours after last known normal time, improved the outcome of patients who had a target mismatch, defined as either clinical-core mismatch or perfusion-core mismatch, which prompted the update of national guidelines in several countries. Accordingly, to provide evidence-based and up-to-date recommendations for ERT in patients with acute LVO in Korea, the Clinical Practice Guidelines Committee of the Korean Stroke Society decided to revise the previous Korean Clinical Practice Guidelines of Stroke for ERT. For this update, the members of the writing group were appointed by the Korean Stroke Society and the Korean Society of Interventional Neuroradiology. After thoroughly reviewing the updated evidence from two recent trials and relevant literature, the writing members revised recommendations, for which formal consensus was achieved by convening an expert panel composed of 45 experts from the participating academic societies. The current guidelines are intended to help healthcare providers, patients, and their caregivers make well-informed decisions and to improve the quality of care regarding ERT. The ultimate decision for ERT in a particular patient must be made in light of circumstances specific to that patient 2).
