Medium vessel occlusion (MeVO) contributes significantly to acute ischemic stroke (AIS). The hypoperfusion intensity ratio (HIR), reflecting collateral circulation via the ratio of Tmax >10s to Tmax >6s volumes, predicts infarct progression in large-vessel occlusions but is unstudied in MeVOs. In this multicenter, multinational retrospective study, we evaluated consecutive patients with MeVO who underwent mechanical thrombectomy with or without intravenous thrombolysis. Inclusion required available follow-up imaging and pretreatment CT perfusion. Follow-up infarct volume (FIV) was measured on CT or MRI 12-36 h post-procedure. Univariable and multivariable linear regression models were used to identify predictors of FIV, with HIR as the …

Faculty, Staff and Student Publications

Introduction: Accurate reconstruction of the femoral head center (FHC) is essential for restoring hip biomechanics in total hip arthroplasty (THA). Previously described age-related morphological changes-such as canal widening and a mediocaudal FHC shift-may complicate anatomical reconstruction in all age-categories using a single non-modular cementless stem. This study assessed the capacity of such implant to achieve adequate FHC reconstruction across age groups and sexes.

Methods: Virtual implantation of a non-modular cementless stem (SL-PLUS™) was performed in CT-based 3D reconstructions of 148 femora from middle-aged (< 80 years) and very elderly (≥80 years) subjects. For each case, the optimal implant size, type (standard or lateral), and modular head (-4 mm, 0 mm or +4 mm) were selected. FHC deviation was measured in three dimensions; reconstructions were considered adequate if < 5 mm in all directions.

Results: Overall, 92.4 % of reconstructions were considered adequate. No significant differences in reconstruction accuracy could …
