Association of Hypotension During Thrombectomy and Outcomes Differs With the Posterior Communicating Artery Patency.

Background And Purpose: Hypotension during endovascular therapy for acute ischemic stroke is associated with worse functional outcomes (FO). Given its important role in intracranial hemodynamics, we investigated whether hypotension during endovascular therapy had the same effect on FO according to the posterior communicating artery (PComA) patency.

Methods: We performed a post hoc analysis of the ASTER trial (Contact Aspiration Versus Stent Retriever for Successful Revascularization).

Effect of Steady and Dynamic Blood Pressure Parameters During Thrombectomy According to the Collateral Status.

Background and Purpose- Guidelines regarding blood pressure (BP) management during endovascular therapy (EVT) for anterior circulation strokes are questionable since the optimal BP target is a matter of debate. To evaluate the importance of hemodynamic control during EVT, we investigated the impact of dynamic and steady BP parameters during EVT on functional outcome (part 1) and according to the collateral status (CS; part 2). Methods- We performed a post hoc analysis of the ASTER trial (Contact Aspiration Versus Stent Retriever for Successful Recanalization).
