Endovascular approaches to treating a diseased ascending aorta are challenging. We report the use of an endovascular occlusion device for successful closure of a ruptured penetrating atherosclerotic ulcer of an ascending aorta. A 47-year-old female patient with Takayasu arteritis complained of a worsening hemoptysis. She had a history of Bentall procedure for a sinus of Valsalva aneurysm and redo surgery for a ruptured penetrating atherosclerotic ulcer close to the distal anastomosis. She developed methicillin-resistant Staphylococcus aureus (MRSA) mediastinitis after the second procedure and required negative pressure wound therapy. Computed tomographic angiography revealed recurrence of a ruptured penetrating aortic ulcer and an aortobronchial fistula. Because of the high risk of redo sternotomy after MRSA mediastinitis, we used an endovascular occlusion device to achieve successful percutaneous closure. The patient was discharged without any complications. Postoperative computed tomography scans showed that the endovascular device was positioned without migration and that complete thrombosis of the penetrating atherosclerotic ulcer was achieved. This is the first report on endovascular repair of a ruptured penetrating atherosclerotic ulcer of the ascending aorta in Takayasu arteritis.

Bibliometric analysis of published works in ocular trauma: a growing focus on open globe injury.
Int Ophthalmol
January 2025
Department of Ophthalmology, Rutgers New Jersey Medical School, Institute of Ophthalmology and Visual Science, Newark, NJ, USA.
Purpose: The purpose of this study is to analyze the trends and characteristics of ocular trauma research published from 2000 to 2022 to delineate the trajectory of the field's research, provide information about the network of key contributors, and help determine future research strategies and direction.
Methods: Web of Science was queried for published works using a series of keywords relating to ocular trauma: "globe rupture", "ruptured globe", "globe injury", "ocular trauma", "intraocular foreign body", "eye trauma", "eye injury", and "traumatic endophthalmitis".

Technical and clinical outcomes of 13 years of endovascular repair of infrarenal, atherosclerotic, penetrating aortic ulcers.
Ann Vasc Surg
January 2025
Department of Vascular and Endovascular Surgery, University Hospital Heidelberg, Heidelberg, Germany.
Objectives: To report the technical and clinical outcomes of endovascular repair of all infrarenal, penetrating aortic ulcers (PAU) that were treated at a single institution over a 13-year period.
Methods: This is a single-center, retrospective observational study. All patients consecutively treated for atherosclerotic, infrarenal PAU were included between 2010 and 2023.
Histological differences among thrombi in thrombotic diseases.
Curr Opin Hematol
January 2025
Department of Pathology, Section of Oncopathology and Morphological Pathology, Faculty of Medicine, University of Miyazaki, Miyazaki, Japan.
Purpose Of Review: This review aims to summarize the histological differences among thrombi in acute myocardial infarction, ischemic stroke, venous thromboembolism, and amniotic fluid embolism, a newly identified thrombosis.
Recent Findings: Acute coronary thrombi have a small size, are enriched in platelets and fibrin, and show the presence of fibrin and von Willebrand factor, but not collagen, at plaque rupture sites. Symptomatic deep vein thrombi are large and exhibit various phases of time-dependent histological changes.
A Narrative Review of Biomarkers and Imaging in the Diagnosis of Acute Aortic Syndrome.
Diagnostics (Basel)
January 2025
Department of Cardiovascular Surgery, Faculty of Medicine, Atatürk University, Erzurum 25030, Türkiye.
Acute aortic syndrome (AAS) encompasses a range of life-threatening conditions, including classical dissection, intramural hematoma, and penetrating aortic ulcer. Each of these conditions presents distinct clinical characteristics and carries the potential to progress to rupture. Because AAS can be asymptomatic or present with diverse symptoms, its diagnosis requires clinical evaluation, risk scoring, and biomarkers such as D-dimer (DD), C-reactive protein (CRP), homocysteine, natriuretic peptides (BNP), and imaging modalities like computed tomography (CT), magnetic resonance imaging (MRI), and echocardiography.

J Pediatr Ophthalmol Strabismus
January 2025
This report describes the longest case of a retained metallic intraorbital foreign body with no complications and development of delayed sensory exotropia following traumatic sclopetaria in childhood. A 9-year-old girl suffered a BB gun injury to the left eye, leading to chorioretinitis sclopetaria and loss of vision. The visual acuity was 20/800 with a relative afferent pupillary defect and choroidal rupture with subretinal hemorrhage that evolved to sclopetaria over time.
