Patent foramen ovale and migraine in ischemic stroke patients: incidence, pathogenetic interrelation and the effects of endovascular closure [PDF]

open access: yesКлиническая практика
BACKGROUND: Migraine is a chronic neurovascular disease with high incidence rate and medical-social significance. Despite more than half a century of studying the disease, the pathogenesis of migraine is not yet completely clear.

The HRAS Variant c.175G>A (p.Ala59Thr) Causes a Predominantly Ectodermal Phenotype Lacking Classic Costello Syndrome Features

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 2, Page 407-418, February 2026.
ABSTRACT Costello syndrome (CS) is a rare dominant HRAS RASopathy characterized by curly hair, cardiac abnormalities, craniofacial anomalies, and developmental delay. HRAS codon 58, 59, and 60 variants are associated with milder phenotypes. We describe a three‐generation family with a previously unreported heterozygous HRAS variant c.175G>A (p.Ala59Thr)

The foramen spinosum: a landmark in middle fossa surgery [PDF]

open access: yes, 2018
The foramen spinosum is an easily identifiable landmark in microsurgery of the middle cranial fossa, and knowledge of the variations in its relationship to the surrounding neurovascular structures is important when operating in this area.

Migraine and vascular disease biomarkers: A population-based case-control study. [PDF]

open access: yes, 2018
Background The underpinnings of the migraine-stroke association remain uncertain, but endothelial activation is a potential mechanism. We evaluated the association of migraine and vascular disease biomarkers in a community-based population.

Platypnea-orthodeoxia due to osteoporosis and severe kyphosis: a rare cause for dyspnea and hypoxemia

open access: yesHeart International, 2011
Platypnea orthodeoxia is a rare disorder characterised by dyspnea and arterial desaturation, exacerbated by the upright position and relieved when the subject is recumbent.

Obstructing Chiari Network Facilitating Blood Flow Across a Patent Foramen Ovale Causing Hypoxia

open access: yesJACC: Case Reports, 2020
A 36-year-old man with progressive dyspnea and hypoxia was found to have a large, partially fenestrated Chiari network accelerating blood flow through a patent foramen ovale with preservation of an embryonic right-to-left atrial flow pattern.

The Correlations of Clinical Outcomes and Vascular Morphology With Infarct Patterns in Middle Cerebral Arterial Occlusion

open access: yesBrain and Behavior, Volume 16, Issue 2, February 2026.
For stroke caused by large vessel occlusion in M1 segment of middle cerebral artery (MCA), a tortuous and long M1 segment of contralateral MCA (cMCA) correlates with the onset of borderzone infarct. In those with a less tortuous cMCA‐M1 segment, a thin and short M1 segment correlates with large infarct.

Secondary stroke prevention: patent foramen ovale, aortic plaque, and carotid stenosis [PDF]

open access: yes, 2017
Stroke is the most debilitating cardiovascular event. It has a variety of causes that may be present simultaneously. In young or otherwise healthy people, the search for a patent foramen ovale (PFO) has become standard.

Atrial Septal Defects [PDF]

open access: yes, 2014
Atrial septal defects are the third most common type of congenital heart disease. Included in this group of malformations are several types of atrial communications that allow shunting of blood between the systemic and the pulmonary circulations.
