Orbital arteriovenous malformations (AVMs) are rare vascular lesions that may be managed with endovascular embolization followed by surgical resection. Embolization is often accomplished with n-butyl-2-cyanoacrylate (nBCA), which is considered to be a safe and effective liquid occlusive agent. Localized vascular inflammation has been associated with endovascular nBCA use in histopathologic studies, but reports of systemic hypersensitivity reactions following endovascular embolization with nBCA are rare. We present a case of a 26-year-old male who developed an intermittent systemic urticarial reaction without cardiopulmonary compromise beginning four weeks after nBCA embolization of an orbital AVM. Subsequent skin allergy testing performed by an allergist confirmed hypersensitivity to nBCA glue and the patient has since been successfully managed with daily oral antihistamines. Awareness of this rare potential complication of endovascular embolization with nBCA will aid in the counseling and management of patients with AVMs.

Cerebral Air Embolism: Process Change with Unintended Consequences.
J Stroke Cerebrovasc Dis
January 2025
UCHealth Memorial Hospital Colorado Springs, Colorado. Electronic address:
Introduction: During a cerebrovascular procedure, diligent care is made to ensure no air is present in lines and connectors. Should air enter the cerebral vasculature, cerebral air emboli can cause worsening neurological outcome or death. This communication outlines how a process change of refrigerating mixed heparin for storage lead to the presence of unintentional air, or off-gassing of the fluid.

Objective: Paravisceral aortic lesions present significant challenges for endovascular treatment. This retrospective analysis of consecutively treated patients from April 2017 to June 2021 aimed to analyse the outcome of primary intra-operative embolisation of aortic complicated pseudoaneurysms and gutter channels during parallel graft (PG) repair of paravisceral symptomatic aortic pseudoaneurysms.
Methods: Patients with symptomatic pseudoaneurysms of the paravisceral aorta treated with PGs using chimney or periscope configurations were included.

Introduction: Meningiomas are the most common primary central nervous system tumors, often requiring surgical resection. Presurgical embolization (PSE) is used to reduce intraoperative bleeding, although its effectiveness varies. This study evaluates the safety and efficacy of PSE using ethyl-vinyl alcohol (EVOH) in meningioma surgeries.

Objective: Infective endocarditis (IE) is associated with significant morbidity and mortality and places patients at risk for subsequent peripheral vascular emboli. Our goals were to analyze the incidence of peripheral emboli and their associated complications and outcomes.
Methods: A retrospective single-center review of all patients with IE from 2013-2021 was performed.
Thromboembolic Complications After Treatment with the INCRAFT AAA Ultra-Low-Profile Stent Graft System.

Department of Vascular Surgery, Inselspital, Bern University Hospital, University of Bern, Switzerland.
Objective: Low-profile endografts have reported increased rates of limb graft occlusions. The INCRAFT stent graft system is an ultra-low profile endograft for the exclusion of infrarenal abdominal aortic aneurysms. Our aim was to report thromboembolic events (TE) in patients treated with the INCRAFT device and its association with risk factors.
