Background: Although it is clear that stroke is a time-dependent and age-associated disease, we still need more evidence regarding the efficacy and outcomes in elderly patients who were excluded from the first trials of mechanical thrombectomy. The aim of this study is to highlight patient characteristics, the timing of medical attention and therapy, successful recanalization, and functional outcomes in patients over 80 y/o who underwent mechanical thrombectomy at the Ospedale Maggiore della Carità di Novara (Hub) since endovascular stroke treatment was first started here. Methods: all 122 consecutive patients over 80 y/o at admission who underwent mechanical thrombectomy between 2017 and 2022 at our Hub center were retrospectively included in our database. A good functional outcome in these elderly patients was considered as the 90 days modified Rankin Scale (mRS) ≤ 3 and/or a decrease in functional status as ∆mRS ≤ 1 in order to interpret the results for patients with intact intellect and basal mRS > 3. Successful recanalization as a score of TICI ≥ 2b (Thrombolysis in Cerebral Infarction) was analyzed as a secondary outcome. Results: Good functional outcome (mRS ≤ 3 and/or ∆mRS ≤ 1) was observed in 45.90% (56/122). The rate of successful recanalization (TICI ≥ 2b) was 65.57% (80/122). Conclusion: Our data confirm that a good outcome in the elderly age group has a correlation with age; being younger, with a milder NIHSS (National Institutes of Health Stroke Scale) at the onset and with a lower pre-morbid mRS is statistically associated with a better outcome. However, age should not be a criterion to exclude older patients from mechanical thrombectomy. Decision-making should take into consideration the pre-morbid mRS and the severity of the stroke on the NIHSS scale, especially in the age group over 85 y/o.

Introduction. Mechanical thrombectomy with ADAP-technique of ischemic stroke has been reported as fast and effective. Aim of this study is to evaluate imaging criteria as possible predictors of stroke severity, therapeutic success, and outcome. Materials and Methods. Patients (30) presenting from October 2015 to April 2017 with Emergent Large Vessel Occlusion of the anterior circulation were treated with ADAP-technique. 22 received also IV tPA; 8 underwent endovascular treatment only. Every patient was evaluated with noncontrast CT, multiphase angiography-CT, and perfusion CT. Clinical and radiological characteristics were measured. Good clinical outcome was an improvement of 8 points on NIHSS at discharge or a modified Rankin Scale ≤2 at discharge and at 90 days. Results. Successful revascularization was obtained in 57% of patients, no procedural complications were witnessed, and only two hemorrhages were reported. Good outcome at discharge was obtained in 11 patients (37%) and predicted by NCCT ASPECT and TICI; outcome at 90 days was predicted by NCCT ASPECT, clot length, and premorbid mRS. Mortality was 23% at discharge and 30% at 90 days. Conclusion. ADAPT is an effective endovascular method of stroke treatment with fast procedural times. Multimodal CT evaluation is effective in assessing stroke severity, providing important prognostic information, which is able to select patients for the appropriate treatment.

Brain health may be threatened by aneurysm ruptures, and early recognition of these vascular malformations allows for neuroradiological intervention. Neurointerventional procedures are usually performed with femoral artery access. In patients with severe anatomical complexity of the supra-aortic vessels, however, treatment by this approach could be hindered or impossible. Flow-diverter stent deployment is an effective and safe treatment for large, wide necked intracranial aneurysms, but it requires a complete and firm stability of the coaxial system to achieve a correct and precise deployment of the device. We present the first reported Italian case of a patient with an intracranial aneurysm which was treated with Flow-diverter stent (DERIVO^®; AcandisGmbH & Co. KG; Pforzheim; Germany) by direct common carotid artery puncture due to severe tortuosity of supra-aortic trunks.

Background: Since the first case of Coronavirus Disease 2019 (COVID-19) in Italy, all the hospital facilities had to reform their daily activities. Amidst them, the Interventional Radiology Department in the “Azienda Ospedaliera Universitaria” of Novara (Italy) had to create a dedicated protocol for the patent's management during the pandemic. Design and methods: The time interval between February 2020 and March 2021 was divided into three different periods and we reported the evolution of our safety protocol, the changes in our daily activities and the rates of SARS-CoV-2 infection among the healthcare workers (HCW) of the Angiographic Suite. Personnel who had positive partners/family members or who had established close contacts of another nature outside the workplace were excluded from the study, in order to reduce any bias. Results: A total of 35 HCWs served in 355 patient procedures on SARS-CoV-2 positive patients from February 2020 to March 2021. During the year there was a reduction in the morbidity rate first from 7.9% to 1.4% and then currently reaching 0%. Conclusions: Dedicated routes, elevators, establishing filter areas and a clear demarcation between clean and contaminated areas, dressing and undressing procedures, cleaning procedures and the obligation to always wear a surgical mask during the working shift are essential to prevent in-hospital infection. The vaccines’ arrival seems to further reduce the risk for healthcare workers, but it is still necessary to take docile precautions in view of the new mutations of the virus.

"Difficult vascular anatomy" is a challenge for Interventional Radiologists especially in liver directed therapies such as trans arterial radio embolization. Trans arterial radio embolization is a long and difficult procedure in which the basic knowledge of hepatic and gastro-enteric vascularization, with its high degree of variations, is very important in order to correctly administer the therapeutic drug selectively. In this report, we present a case of an atypical patient affected by an unresectable hepatocellular carcinoma, candidate for Radio-embolization treatment. His vascular anatomy was very difficult to manage, but the Interventional Radiologist was not only able to go over the "difficult anatomy," but also to take advantage of it.
