Concurrent Use of Contact Aspiration and a Stent Retriever Is Associated With Successful Recanalization in Patients With Cancer-Associated Stroke

Background and PurposeThe optimal thrombectomy technique in emergent large vessel occlusion due to cancer-associated coagulopathy remains uncertain.We aimed to investigate the efficacy and safety of concurrent contact aspiration and stent retriever in this stroke subtype. MethodsWe retrospectively analyzed consecutive ischemic stroke patients who had undergone endovascular thrombectomy.Patients were characterized as having cancer-associated stroke (CAS) or non-cancer-associated stroke (non-CAS).Thrombectomy technique was classified as a single strategy (either contact aspiration or a stent retriever) or a combined technique (concurrent use of contact aspiration and a stent retriever at least once).Successful recanalization was defined as a modified TICI grade 2b or 3 at the end of the procedure.Factors associated with successful recanalization were analyzed. ResultsThe present study enrolled 393 patients.Of these patients, 56 (14.2%) were found to have cancer-associated stroke.Rates of recanalization (69.6% vs. 91.7%,p
