Multicenter Study
Effects of first pass recanalization on outcomes of contact aspiration thrombectomy.
First pass recanalization (FPR, defined as achieving a modified Thrombolysis in Cerebral Ischemia (mTICI) grade 2c/3 with a single pass of a thrombectomy device) effect has not yet been evaluated in contact aspiration thrombectomy (CAT). We evaluated FPR effect on clinical outcomes and FPR predictors in CAT. ⋯ Patients in the FPR group had better clinical outcomes than the non-FPR group in CAT. FPR was independently associated with a good outcome. The use of a balloon guide catheter was the only predictor of FPR.

Symptomatic intracerebral hemorrhage (sICH) is a devastating complication after endovascular thrombectomy. Prior reports have demonstrated that thrombolysis in cerebral infarction (TICI) ≥2 b reperfusion is protective against sICH. We aimed to further examine the relationship between reperfusion grade and sICH, to elucidate whether a difference between TICI 2b and 3 exists, and to determine whether this relationship holds true for patients undergoing delayed thrombectomy (6-24 hours). ⋯ Higher baseline ASPECTS and higher degree of reperfusion following endovascular thrombectomy is associated with reduced likelihood of PH and sICH.

There are few data in the literature on the characteristics and natural history of intracranial arterial infundibular dilatations in children. ⋯ We present the largest reported cohort of pediatric intracranial arterial infundibula, which we found to be distinct from their adult counterparts with regard to location, etiology and temporal evolution. Growth over time and/or aneurysmal formation are rare, not necessitating frequent short-term imaging surveillance during childhood.

Observational Study
Efficacy and safety of the dual-layer flow-diverting stent (FRED) for the treatment of intracranial aneurysms.
To describe the efficacy and complications of treating cerebral aneurysms with the Flow Re-direction Endoluminal Device (FRED) and to identify predictors for aneurysm occlusion. ⋯ The FRED stent fully complied with efficacy and safety requirements for treatment of intracranial aneurysms. Three predictors of aneurysm occlusion were identified.

To determine the effect of general anesthesia (GA) versus conscious sedation (CS) on radiation exposure (RE), procedure time (PT), and fluoroscopy time (FT) in patients receiving endovascular stroke treatment (EST) for large vessel occlusions (LVOs) in the anterior circulation. ⋯ In this retrospective analysis, no effect of the mode of anesthesia on the radiation exposure during EST was detected as GA and CS showed comparable PT, FT, and DAPs.
