CAPTIVE: continuous aspiration prior To intracranial vascular embolectomy. Deployment of stent-retriever under aspiration from catheter proximal to the thrombus (A), removal of microcatheter and advancement of aspiration catheter (B) and removal of stent-retriever, aspiration catheter and thrombus as a unit (C). SAVE: Stent-retriever Assisted Vacuum-locked Extraction technique. Deployment of stent-retriever, removal of the microcatheter and initiation of aspiration (D), advancement of the aspiration catheter to the proximal tip of the thrombus (E) and removal of stent-retriever, aspiration catheter and the thrombus as a unit under aspiration suction (F). ARTS: Aspiration-Retriever Technique for Stroke: Placement of an aspiration catheter proximally to thrombus (G), deployment of stent-retriever under constant aspiration (H), inflation of BGC and retrieval of the stent-retriever, the thrombus and the aspiration catheter as a unit through the BGC (I). STRAP: Stent Retrieval - Aspiration and Proximal Flow Arrest Placement of an aspiration catheter proximally to the thrombus (J), deployment of a stent-retriever and initiation of aspiration from aspiration catheter and BGC (K), followed by retrieval under constant suction (L). BADDASS: Balloon Guide with Large Bore Distal Access Catheter with Dual Aspiration with Stent-retriever as Standard. Partial deployment of stent-retriever with or without aspiration catheter on (M), advancement of aspiration catheter to proximal portion of thrombus, full deployment of the stent-retriever and removal of microcatheter (N), inflation of BGC and thrombus retrieval under constant suction from distal catheter and BGC (O). ASAP: A Stent-Retrieving into an Aspiration Catheter with Proximal Balloon Technique. Deployment of stent-retriever at the site of the thrombus while the aspiration catheter is under suction and BGC is inflated (P), the stent-retriever is the retrieved inside the aspiration catheter (Q) followed by removal of the aspiration catheter under continuous suction (R). PROTECT: Proximal Balloon Occlusion Together with Direct Thrombus Aspiration. Deployment of a stent-retriever at the site of the thrombus while suction is applied through the aspiration catheter and manual suction is done through the inflated BGC (S) followed by retrieval under constant suction through the aspiration catheter and through the BGC (T).
