ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

Hepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Radiosurgery for Arteriovenous Malformations

JBNC - JORNAL BRASILEIRO DE NEUROCIRURGIA, 2011
Radiosurgery has become a popular alternative to microsurgery for small arteriovenous malformations (AVM). Numerous reports document high obliteration rates (around 80%) and low radiation induced complication rates (around 2%). Gamma knife, linear accelerator, and particle beam systems are all viable options.

Arteriovenous Malformation of Face

Contemporary Clinical Dentistry, 2017
Arteriovenous malformations (AVMs) are rare congenital vascular malformations accounting only 1.5% of all vascular anomalies with 50% occurrence in the oral and maxillofacial region. It usually results from birth defects of the vasculature. A literature search revealed only few case reports of AVMs in the facial region.

Renal arteriovenous malformation presenting with massive hematuria

Radiology Case Reports, 2015
Renal arteriovenous malformations are abnormal communications between the intrarenal arterial and venous systems. They are a rare cause of hematuria. Color Doppler ultrasonography, multislice CT angiography, and DSA are important tools for making the ...

Pulmonary Arteriovenous Malformations [PDF]

American Journal of Respiratory and Critical Care Medicine, 2014
Within the past decade, pulmonary arteriovenous malformations (PAVMs) have evolved from rare curiosities to not uncommon clinical states, with the latest estimates suggesting a prevalence of ~1 in 2,600. PAVMs provide anatomic right-to-left shunts, allowing systemic venous blood to bypass gas exchange and pulmonary capillary bed processing.

Cardiac Arteriovenous Malformation

Journal of the American College of Cardiology, 2010
![Figure][1] [![Graphic][3] ][3][![Graphic][4] ][4] A 31-year-old woman with anxiety was seen by her primary care physician for progressive fatigue. Her electrocardiogram showed a left axis deviation, but was otherwise unremarkable.

Intracranial arteriovenous malformations

Diagnostic and Interventional Imaging, 2014
Intracranial arteriovenous malformations (AVM) are rare lesions that are often discovered fortuitously. They should be identified on CT scan and MRI before resorting to angiography; the latter is used to prepare the treatment. This article describes the various types of subpial or dural AVM and the specific characteristics that enable their ...

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

Advanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.
