The ASH guidelines define the treatment period of acute DVT/PE as "initial management" (first 5-21 days), "primary treatment" (first 3-6 months), and "secondary prevention" (beyond the first 3-6 months). Thrombectomy is most commonly used in acute cerebral ischemic stroke, although it is also a procedure used for clot removal in acute myocardial infarction (MI) and pulmonary embolism (PE). Defining the criteria to evaluate and select patients with ELVO for endovascular treatment is critically important, since between 3% and 22% of patients with AIS are potentially eligible for mechanical thrombectomy, depending on the specific selection criteria used.5-7 Time of symptom onset (or last known well, magnitude of early ischemic change on initial . 10.1016/j.jcin.2018.12.022; Behrens G, Bjarnason H: Venous thromboembolic disease: the use of the aspiration thrombectomy device AngioVac.
