Background: Recognition of rates and causes of hard, patient-centered outcomes of death and cerebrovascular events (CVEs) after heart rhythm disorder management (HRDM) procedures is an essential step for the development of quality improvement programs in electrophysiology laboratories. Our primary aim was to assess and characterize death and CVEs (stroke or transient ischemic attack) after HRDM procedures over a 17-year period.
Background: The impact of carotid artery stent fractures on the incidence of adverse clinical events remains unclear. The objective of this study is to report the stent fracture rate and its association with in-stent restenosis and adverse outcomes in the ACT-1 trial (Carotid Angioplasty and Stenting Versus Endarterectomy in Asymptomatic Subjects Who Are at Standard Risk for Carotid Endarterectomy With Significant Extracranial Carotid Stenotic Disease).
Ultrasound‐assisted catheter‐directed thrombolysis therapy has emerged more recently as a management strategy for patients with intermediate risk pulmonary embolism and has shown promising results in clinical trials by early reversal of right ventricle dilation, reduced pulmonary hypertension, and decreased anatomic thrombus burden. This therapeutic strategy requires a small fraction of the systemic fibrinolytic dose and is therefore associated with a reduced bleeding risk. Although intracranial hemorrhage has not been reported in clinical trials, it is a possible complication. Here we report the first case of intracranial hemorrhage related to the use of EkoSonic™ Endovascular System directed thrombolysis in a patient with large bilateral pulmonary embolism without any identifiable bleeding risks.
Purpose: Idiopathic intracranial hypertension (IIH) is a disorder of increased intracranial pressure in the absence of any known causative factor. Sinus stenosis is common in these patients. Stenting of stenotic dural sinuses has gained popularity as a treatment option, since these stenoses may contribute to an obstruction of the venous return, and, thereby may contribute to IIH via an increase in venous sinus pressure. We evaluated the safety and efficacy of endovascular treatment in IIH with venous sinus stenosis.
Introduction: Near-occlusion of the internal carotid artery (ICA) is a significant luminal diameter (LD) reduction beyond a tight atherosclerotic carotid stenosis (CS). Recognition of even subtle near-occlusions is essential to prevent underestimation of the stenosis degree. Our goal was to investigate the prevalence of near-occlusion among CS patients using a single standard criterion to facilitate its recognition, even when distal ICA LD reduction is not visually evident in computed tomography angiography (CTA).
Introduction: Ventral sulcus spinal cord arteriovenous shunts (SCAVS) are rare vascular lesions that are located outside the spinal cord, are exclusively vascularized by the anterior spinal axis, and drain exclusively through the anterior spinal vein. We report the anatomical, clinical, and neuro-radiological features of SCAVS managed by our team.
Introduction: The study aimed to compare efficacy and safety of aspiration thrombectomy (AT) to stentriever thrombectomy (SRT) in patients with basilar artery (BA) occlusion (BAO).
Introduction: The Leo stent was the first retrievable stent for endovascular treatment of intracranial aneurysms (IAs). We report our experience with this device with emphasis on very long-term follow-up.
Introduction: The p64 flow diverter (FD) device is a fully resheathable and detachable stent dedicated for endovascular treatment (EVT) of intracranial aneurysms (IAs). We report our mid-term experience with this device.
Introduction: Haemorrhagic transformation of acute ischemic stroke (AIS) and particularly parenchymal haemorrhage (PH) remains a feared complication of intravenous thrombolysis (IVT). We aimed to identify clinical and perfusion CT (PCT) variables which are independently associated with PHs.
Introduction: In acute internal carotid artery dissection (a-ICAD) with concomitant intracranial large vessel occlusion or haemodynamic impairment, the effectiveness of medical treatment is limited and endovascular therapy (EVT) can be considered. Feasibility, safety and outcome of EVT in a-ICAD are not well described yet.
BACKGROUND AND PURPOSE: Resistance to blood flow in the cerebral drainage system may affect cerebral hemodynamics. The objective of the present study was to use phase-contrast MRA to quantify resistance to drainage of blood across branches of the venous sinus tree and to determine whether the resistance to drainage values correlated with internal jugular vein outflows.
Purpose: Long-term data on aneurysm treatment with flow-diverting stents are still sparse, and follow-up protocols differ widely between institutions. We present long-term results, with a focus on the usefulness of contrast-enhanced MR angiography (ceMRA).
Background: Transcatheter aortic valve implantation (TAVI) has emerged as a safe and effective treatment for patients with severe, symptomatic aortic valve stenosis at high surgical risk over the last years. However, besides its minimal invasive character, TAVI still is an invasive procedure usually performed in a population, carrying a substantial risk for vascular complications, like stroke. Stroke is known to be a rare but serious complication of transvascular interventions in clinical practice, which is associated with high morbidity and mortality rates. Despite broad clinical research in many fields of TAVI over the last years, only sparse data still exist on the incidence and clinical risk factors of stroke complicating TAVI in clinical practice today.
Objective: To compare the complication rates associated with carotid endarterectomy (CEA) versus carotid artery stenting (CAS).
