Background and Aim: Recent studies have shown that the CT Perfusion (CTP) parameter of rCBV < 42 % lesion volume can predict 90-day functional outcomes in stroke patients. However, its correlation with discharge outcomes, including functional dependence, has not been investigated. Our study aims to evaluate the relationship between rCBV < 42 % and poor functional outcomes at discharge, defined as a modified Rankin score (mRS) of 3 or higher., Materials and Methods: This retrospective study analyzed patients with confirmed occlusion on CT angiography, who also received CT perfusion between 9/1/2017 and 10/01/2023. Statistical tests (Student's T, Mann-Whitney U, and Chi-Square) were used to assess differences. Univariable and multivariable logistic regression analyses were performed to evaluate the associations of rCBV < 42 % with discharge mRS. A p-value ≤ 0.05 was considered significant., Results: A total of 268 patients [median age: 68 years (IQR: 59-77), 56.3 % female] met the inclusion criteria. Among them, 85 patients (31.7 %) received intravenous thrombolysis (IVT), and 221 patients (82.5 %) underwent mechanical thrombectomy (MT). After adjusting for various variables, logistic regression analysis indicated that rCBV < 42 % lesion volume was associated with poor functional outcomes at discharge (aOR = 0.97, p < 0.05). T., Conclusion: The rCBV < 42 % could be a valuable tool in prognosticating AIS-LVO patients., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Drs.

Whilst surgical resection is traditionally used for the successful eradication of locally aggressive osseous tumors, it is often hazardous or unachievable, particularly in complex anatomic sites, such as the pelvis and spine. The authors present the use of microwave ablation in combination with Zoledronic acid (ZA) administration, alone and with the use of ZA-loaded polymethyl methacrylate (PMMA) to percutaneously treat unresectable bone tumors in 4 patients with giant cell tumors (GCT), multiple myeloma (MM) and breast cancer metastasis., (Copyright © 2020 Elsevier Ltd.
