Intraosseous Mandibular Venous Malformation

Journal of Craniofacial Surgery, 2011
Intraosseous venous malformations are rare benign lesions that account for approximately 0.5% to 1% of all osseous tumors. Involvement of the facial skeleton is rather uncommon, with the mandible and maxilla most frequently involved. In the current study, we report a case of an intraosseous venous malformation in a 52-year-old male patient with a ...

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

Advanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

MRI evaluation of soft tissue vascular malformations

Indian Journal of Radiology and Imaging, 2020
Background: Soft tissue vascular malformations are not uncommonly encountered in clinical practice and are often mistaken for other pathologies. Vascular anomalies are divided into vascular tumors and malformations.

Pathophysiology of Slow-Flow Vascular Malformations: Current Understanding and Unanswered Questions

Journal of Vascular Anomalies, 2023
Background:. Slow-flow vascular malformations include venous, lymphatic, and lymphaticovenous malformations. Recent studies have linked genetic variants hyperactivating either the PI3K/AKT/mTOR and/or RAS/RAF/MAPK signaling pathways with slow-flow ...

Allelic and locus heterogeneity in inherited venous malformations

, 1999
Venous malformations are low-flow vascular lesions consisting of disorganized thin-walled vascular channels. These can occur sporadically but also as an autosomal dominant condition termed venous malformations, cutaneous and mucosal (VMCM; OMIM 600195 ...

Spatially Controlled Embedded Bioprinting of Prevascularized Spheroids‐Containing Biopatch Enables Functional Skin Regeneration

Advanced Healthcare Materials, EarlyView.
A spatially controlled embedded bioprinting strategy enables precise engineering of prevascularized multicellular spheroids within skin‐derived dECM bioinks. Optimized spheroid size, composition, and spacing promote vascular maturation, paracrine signaling, and tissue integration, resulting in enhanced angiogenesis, blood perfusion, and functional skin

Extracranial association of arteriovenous and venous malformations. Case report. [PDF]

, 2013
Association of multiple vascular malformations of the face is a rare condition. An arteriovenous malformation (AVM) with a venous malformation as the draining vein is also a rarity.

Developmental Venous Anomaly Serving as a Draining Vein of Brain Arteriovenous Malformation

Acta Clinica Croatica, 2017
Developmental venous anomalies are cerebral vascular malformations that present normal venous drainage of cerebral tissue. With increased and accessible usage of modern diagnostic tools, they are now one of the most commonly diagnosed cerebral vascular ...

Orbital Lymphatic-Venous Malformation Accompanied by an Intraocular Vascular Malformation: A Rare Case Study

Case Reports in Ophthalmology, 2021
Lymphatic-venous malformations (LVMs) are development defects that result in abnormal connections between the lymphatic and venous systems. The authors describe a 7-weeks-old female infant who presented with a right orbital LVM extending to the ...

Magnetoactive Hydrogels to Probe Curvature‐Directed Endothelial Cell Mechanosensing

Advanced Healthcare Materials, EarlyView.
This work establishes a platform to investigate local curvature as a regulator of endothelial mechanosensing independent of shear stress. Magnetoactive hydrogels enable on‐demand curvature of endothelial monolayers to reproduce tortuosity quantified by clinically established metrics.
