First-pass effect of mechanical thrombectomy for anterior circulation large vessel occlusion: incidence, predictors, and clinical impact. Insight from the ANGEL-ACT registry.
The objective of this study was to investigate the incidence and predictors of first-pass effect (FPE) and to compare the clinical outcomes among FPE, multiple-pass effect, and incomplete reperfusion (ICR) in acute anterior circulation large vessel occlusion. ⋯ FPE was achieved at a rate of 27.0% and associated with functional independence, decreased intraprocedural complications, and ICH. Non-ICA occlusion and underlying ICAD were predictors of FPE.

On the stability of Leksell Vantage stereotactic head frame fixation in Gamma Knife radiosurgery: a study based on cone-beam computed tomography imaging and the High Definition Motion Management system.
The authors' objective was to investigate the stability of the newly introduced Vantage stereotactic frame fixation in single-fraction Gamma Knife radiosurgery. ⋯ This work demonstrated that the Vantage frame possess the same degree of submillimeter stability as the well-established Leksell Coordinate Frame G (G-frame). Displacements between CT and CBCT1 were 3 times higher than between CBCT1 and CBCT2. A suggested HDMM threshold of 1.2 mm ensures a target accuracy within 0.2 mm in Vantage frame treatments.
