Introduction: Clinical outcomes after interventional stroke treatment rely on several factors, with older age being associated with poorer results, which are mainly attributed to patient's comorbidities and medications. The delivery of an aspiration catheter could be hindered by carotid tortuosity, which is more prevalent in elderly patients with increasing age. In this study, we aimed to compare the clinical and angiographic outcomes of a direct aspiration first-pass technique in interventional stroke treatment for elderly patients compared with younger patients.
Materials And Methods: A total of 162 patients (92 women and 70 men, aged between 35 and 94 years +/- 12.4 years) were included in this study. Patients who were treated in a comprehensive stroke center due to a large-vessel occlusion stroke using aspiration as the first-choice treatment were included in this study. To evaluate carotid arteries, the tortuosity index (TI) was calculated for each segment of each carotid pathway.
Results: Age correlated significantly with the presence of carotid tortuosity ( = 0.408, = 0.000), extracranial length ratio ( = 0.487, = 0.000), and overall length ratio ( = 0.467, = 0.000). No significant associations were found with coiling, kinking, or intracranial length ratio. Successful aspiration-based recanalization rate decreased with increasing age, and the differences between the age subgroups were not statistically significant. A comparison of the extreme subgroups, i.e., <60 years old vs. ≥80 years old, did not yield a statistically significant change ( = 0.068).
Conclusion: Successful aspiration-based recanalization rate decreased with increasing age; however, these differences were not significant. Clinical outcomes did not significantly differ with regard to carotid tortuosity, regardless of the time of assessment. Neither intracranial nor extracranial tortuosity was significantly associated with reperfusion-related complications in either of the age subgroups.

Importance: Monoclonal antibodies (mAbs) targeting calcitonin gene-related peptide (CGRP) or its receptor (anti-CGRP mAbs) offer effective migraine-specific preventive treatment. However, concerns exist about their potential cardiovascular risks due to CGRP blockade.
Objective: To compare the incidence of cardiovascular disease (CVD) between Medicare beneficiaries with migraine who initiated anti-CGRP-mAbs vs onabotulinumtoxinA in the US.

The number of atrial catheter ablation procedures has significantly increased in recent years, becoming a first-line treatment modality for various supraventricular tachycardias due to their safety and efficacy. Complications, ranging from mild to life-threatening, can arise during different stages of the procedure, including vascular access complications (eg, hematoma or vascular fistula formation, retroperitoneal bleeding, etc.), thromboembolic complications (eg, stroke, transient ischemic attack, air embolism, etc.

Spontaneous intracranial artery dissection (sIAD) is the leading cause of stroke in young individuals. Identifying high-risk sIAD cases that exhibit symptoms and are likely to progress is crucial for treatment decision-making. This study aimed to develop a model relying on circulating biomarkers to discriminate symptomatic sIADs.

Objective: This study aimed to evaluate the clinical efficacy and safety of minimally invasive hematoma evacuation for the treatment of traumatic intracranial hematoma (TIH).
Methods: Ninety patients diagnosed with traumatic intracerebral hematoma at Shengli Oilfield Central Hospital from August 2019 to September 2023 were selected as the study subjects. The patients were divided into the craniotomy group (C group, n = 45) and the minimally invasive hematoma evacuation group (MIHE group, n = 45).

Background: Hypotension during anesthesia for surgery for hip fracture is common and associated with myocardial injury, stroke, acute kidney injury, and delirium. We hypothesized that maintaining intraoperative blood pressure close to patients' preoperative values would reduce these complications compared to usual care.
Methods: A pilot feasibility patient- and assessor-blinded parallel group randomized controlled trial.
