A direct aspiration first-pass technique (ADAPT) for acute ischemic stroke thrombectomy: Indications, technique, and emerging devices.

To date, the use of the most suitable first-pass technique for Mechanical Thrombectomy is still debated. In last years, several observational studies have suggested noninferiority or superiority of A Direct Aspiration first-Pass Technique (ADAPT) technique to achieve better reperfusion in comparison to stent retriever. While ASA/AHA 2018 guidelines recommend that patients with AIS should receive Mechanical Thrombectomy with a stent retriever, last European Stroke Organization guidelines report no evidence that stent retriever compared with contact aspiration could improve reperfusion rate. ADAPT is based on aspiration alone as the primary mechanism of thrombectomy and, if initially unsuccessful, then incorporating adjunctive alternatives. ADAPT improvement is also related to last generation of aspiration catheters. The purpose of this review is to report ADAPT principles, technique, efficacy, and safety as first-line treatment for acute ischemic stroke with the latest generation of reperfusion devices.
