    Objective: The efficacy of intravenous (IV) recombinant tissue plasminogen activator (rt-PA) therapy in the treatment of acute ischemic stroke (AIS) has been demonstrated in many studies and IV rt-PA therapy has been increasingly used all over the world. Early neurological deterioration (END) in AIS is common and potentially associated with a poor clinical outcome. The prevalence of END in AIS ranges from 13% to 37% in studies. The aim of this study is to determine the prevalence and risk factors of END in patients with AIS receiving IV rt-PA therapy. Materials and Methods: One hundred fifty seven patients who were given IV rt-PA treatment by Bursa Uludag University Faculty of Medicine, Department of Neurology between 01.01.2020 and 01.01.2021 were retrospectively included in this study. It was planned to determine the risk group by comparing patients with END with those without. Results: Age (p=0.023), serum glucose level (p=0.045), The National Institutes of Health Stroke score at discharge (p<0.01), Alberta Stroke Program Early CT (ASPECT) score (p<0.01) when clinical, radiological and demographic data associated with END were evaluated and, statistically significant correlation was found with the presence of major vessel occlusion (p=0.012), ischemic stroke due to cardioembolism (p=0.002), clinical outcome (p<0.001) and symptomatic intracerebral hemorrhage (p<0.001). When the significant variables associated with END were evaluated with binary logistic regression, the most significant variables were found to be age (p=0.006) and ASPECT score (p<0.001). Conclusion: The causes of END are multifactorial. The most associated risk factors were found to be advanced age and low ASPECT score. It was understood that the most common cause of END was the inability to perform mechanical thrombectomy for major vessel occlusion. Contrary to popular belief, the most common cause of END in patients with AIS who received IV rt-PA treatment was not considered to be symptomatic intracranial hemorrhage but to inadequate recanalization or late recanalization.

    The relationship between early neurological deterioration, poor clinical outcome, and venous collateral score in cerebral venous sinus thrombosis
    (Wolters Kluwer Medknow Publications, 2021-07-01) Dinç, Yasemin; Özpar, Rıfat; Hakyemez, Bahattin; Bakar, Mustafa; DİNÇ, YASEMİN; ÖZPAR, RİFAT; HAKYEMEZ, BAHATTİN; BAKAR, HACI MUSTAFA; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Radyoloji Anabilim Dalı; Bursa Uludağ Üniversitesi/Tıp Fakültesi/ Nöroloji Anabilim Dalı; 0000-0001-6649-9287; 0000-0002-3425-0740; 0000-0003-0342-5939; IWC-9957-2023; AAH-5062-2021; AAI-2318-2021; EKN-8251-2022
    Background and Purpose: Cerebral venous sinus thrombosis (CVST) is one of the rare causes of cerebrovascular disease and has an extremely heterogeneous prognosis. The aim of this study was to investigate the potential relationship between early neurological deterioration, poor clinical outcome in CVST and the venous collateral score. Materials and Methods: A total of 121 patients diagnosed with CVST between 2010 and 2020 were retrospectively included. The demographic, clinical, and radiological findings related to venous sinus thrombosis and early neurological deterioration were investigated in relation to the clinical outcome. Results: The factors associated with early neurological deterioration were superior sagittal sinus thrombosis (P < 0.001), sinus rectus thrombosis (P = 0.031), parenchymal lesions (P < 0.001), and venous collateral score (P < 0.001). The factors associated with poor clinical outcome were superior sagittal sinus thrombosis (P < 0.001), cortical vein thrombosis (P < 0.001), venous collateral score (P < 0.001), and initial clinical symptoms. Binary logistic regression analyses revealed poor clinical outcome as a significant variable, with a venous collateral scale of 0 or 1 as a risk factor for a poor outcome (significance of the model P < 0.001). Conclusion: Early neurologic deterioration and poor clinical outcome may occur due to poor collateralization in CVST. Identifying the subgroup of CVST patients at risk of clinical deterioration is therefore important. This study highlights the clinical importance of venous collaterals; however, larger prospective multicenter studies are required to confirm the relationship with venous collaterals in patients with CVST.
