Background and purpose Endovascular Mechanical Thrombectomy is the established standard of treatment for acute ischemic strokes for patients with large-vessel occlusions. Mechanical Thrombectomy techniques are well established in the literature which include many direct catheter aspirations and a choice of various stent retrievers or a combination of the above. Additionally some recent clinical studies demonstrate better procedural and clinical outcomes with balloon guide catheters vs other vascular accessories catheters.

Materials and methods We retrospectively compiled and reviewed the clinical and imaging outcomes of the last 20 consecutive patients who presented with acute intracranial LVO (January 2, 2019 - March 13, 2019) who were treated with emergent MT with concomitant stent retriever and’Dual Aspiration Technique’- (Penumbra and Stryker Aspiration at the level of both distal access catheter and carotid/vascular access sheath catheter).

Results Pt age range 59–105 years, average age-78.5 years, TICI 3 - 9 patients, TICI2 B - 10 Patients, TiCI 2A - 1, Successful recanalization rate% TICI 2B/3 - 95%. Average time to repefusion- 53.6 minutes. Failure rate- 0%.

Conclusion Mechanical thrombectomy utilizing stent retriever and concomitant Dual Aspiration Technique appears to be feasible and effective for removal of thrombus in patients with AIS for LVO with high success rate of recanalization. Short/midterm clinical data is however needed to for these patients.
