BACKGROUND: Epistaxis is the most frequent and disabling manifestation of hereditary hemorrhagic telangiectasia (HHT). The efficacy of intravenous bevacizumab (an anti-vascular endothelial growth factor monoclonal antibody) for epistaxis has been shown. However, the efficacy of intranasal bevacizumab has yet to be evaluated. OBJECTIVE: To evaluate the efficacy of 3 different doses of bevacizumab administered as a nasal spray in a repeated manner for the duration of nosebleeds in patients with HHT...

The circulatory system is walled off by different cell types, including vascular mural cells and podocytes. The interaction and interplay between endothelial cells (ECs) and mural cells, such as vascular smooth muscle cells or pericytes, play a pivotal role in vascular biology. Endoglin is an RGD-containing counter-receptor for β1 integrins and is highly expressed by ECs during angiogenesis. We find that the adhesion between vascular ECs and mural cells is enhanced by integrin activators and inhibited upon suppression of membrane endoglin or β1-integrin, as well as by addition of soluble endoglin (SolEng), anti-integrin α5β1 antibody or an RGD peptide...

The aim of this study is to identify the demographics and epistaxis burden of hereditary hemorrhagic telangiectasia (HHT). A questionnaire was sent to participants with HHT who were recruited from a prospectively maintained respiratory clinic data base in a tertiary hospital. Details on demographics, HHT symptoms, family history, epistaxis severity, and treatment received were recorded. There were 34 of 60 responses (57%). Two responses were from families of the deceased. Of the 32 evaluable patients (men, 14; women 18), the average age was 51 years (range, 23-78 years)...

PURPOSE: Spontaneous superior ophthalmic vein thrombosis (SOVT) is a rare entity. We describe three patients with spontaneous ophthalmic vein thrombosis, each with various risk factors. PATIENTS AND METHODS: A retrospective review of three patients with a diagnosis of superior ophthalmic vein thrombosis. Clinical characteristics, radiographic features, management techniques and outcomes are described. RESULTS: All patients presented with unilateral painful proptosis...

Endoglin (ENG), a co-receptor for several TGFβ-family cytokines, is expressed in dividing endothelial cells alongside ALK1, the ACVRL1 gene product. ENG and ACVRL1 are both required for angiogenesis and mutations in either gene are associated with Hereditary Hemorrhagic Telangectasia, a rare genetic vascular disorder. ENG and ALK1 function in the same genetic pathway but the relative contribution of TGFβ and BMP9 to SMAD1/5/8 activation and the requirement of ENG as a co-mediator of SMAD phosphorylation in endothelial cells remain debated...

BACKGROUND: A 42-year-old man with no cardiovascular risk factors or history was admitted for evaluation of an episode of transient ischaemic attack (TIA). He had no cardiovascular risk factors and his physical examination was unremarkable. INVESTIGATION: Physical examination, electrography, transesophageal echocardiogram, coronary angiogram. DIAGNOSIS: Intrapulmonary shunting, in the presence of arteriovenous malformations, possible hereditary haemorrhagic telangectasia...

We present a case of a 62-year-old lady who was a known case of hereditary haemorrhagic telangectasia (Rendu-Osler-Weber syndrome) and had pulmonary arteriovenous malformations (AVMs). She had multiple embolisations of pulmonary AVMs. During the last embolisation therapy, one of the coils migrated into the heart. This could not be located by transoesophageal echocardiography, however, was identified in the left ventricle by computerised tomogram scan. It was removed successfully using cardiopulmonary bypass...

Hereditary hemorrhagic telangectasia (HHT), also known as Osler-Weber-Rendu disease, is an autosomal dominant vascular dysplasia with high penetrance and variable expressivity. A wide variety of neurological complications have been reported in association with this condition. We report the first case of spinal cord infarction likely due to paradoxical embolization with HHT and review the literature on the neurological complications of this disorder. MEDLINE was employed to identify all published reports of HHT with neurological complications...

Recurrent massive epistaxes due to heriditary haemorrhagic telangectasia were managed in two patients by ablation of the mucosa of the nasal and maxillary cavities and resurfacing with radial forearm fasciocutaneous free flaps. Both patients had undergone multiple procedures attempting to control the epistaxes prior to the definitive procedures described. Both patients remained epistaxis free postoperatively and retained their nasal airways. Olfactory function was preserved in the second patient due to preservation of the superior turbinate and cribriform olfactory mucosa...

OBJECTIVE: To review the authors' experience with transcatheter closure of pulmonary arteriovenous malformations (PAVMs) using amplatzer duct occluder (ADO) devices and vascular plugs (AGA Medical, Golden Valley, MN) and present a novel technique for delivery sheath placement and device delivery. BACKGROUND: PAVMs can cause cyanosis, fatigue, polycythemia, and thromboembolic phenomena. Transcatheter closure using coils, detachable balloons, and various devices has replaced surgery as the preferred therapy...

Hereditary Hemorrhagic Telangiectasia (HHT) is a rare genetic disease characterized by mutations occurring in the endoglin and ALK-1, two receptors of transforming growth factor-beta1. From a pathogenic point of view, a possible involvement of the immune system in HHT has been suggested since a mononuclear cell infiltrate was found around the area of telangiectases. Up until now, no information has been available about the role played by leukocytes in HHT and the mechanisms elicited by secretion of their mediators...

BACKGROUND AND PURPOSE: A minority of patients with spinal arteriovenous malformations (SAVM) are symptomatic as neonates or infants. We analyzed the clinical and anatomic factors associated with this early presentation, and reviewed our experience in treating patients with these lesions. METHODS: A retrospective review of clinical records and imaging studies was performed for patients with SAVM who presented at less than 2 years of age and who were examined by the diagnostic and interventional neuroradiology service at our institution...

Osler Weber Rendu Disease is an hereditary haemorrhagic télangectasia habitually revealed by reccurent bleeding (epistaxis). Hepatic involvement in Osler disease is found in 8 to 31%, manifested by cholestasis. We report an original observation of a cholangitis revealing Osler disease.

Understanding the features of the various hereditary vascular pathologies allows consideration and confirmation of the diagnosis, and a search for treatable hidden disorders, avoiding harmful investigations, initiating follow up, performing family investigations and providing genetic counselling. Pseudoxanthoma elasticum must be considered in the presence of calcified distal arteriopathy of the lower limbs in a young subject without any other aetiological aspects. Cutaneous or mucosal lesions confirmed on histological examination, angioid streaks at the back of the eye and a family history support the diagnosis, which is confirmed by showing pathogenic mutations of the ABCC6 gene...

BACKGROUND: Most congenital pulmonary arteriovenous malformations are associated with hereditary hemorrhagic telangiectasia. During pregnancy, pulmonary hemorrhage can occur, compromising maternal and fetal health. CASES: We studied three pregnancies in two women with hemorrhagic telangiectasia complicated by pulmonary arteriovenous malformations. A 28-year-old primigravida's fetus died at 25 weeks' gestation, and she had embolotherapy with coil springs, which corrected the hypoxemic state...

Pulmonary arteriovenous fistula are an uncommon disorder, and are most frequently congenital, usually then associated with hereditary hemorrhagic telangectasia (Rendu-Osler-Weber disease). We present, to our knowledge, the first case of a pulmonary arteriovenous fistula detected by gadolinium-enhanced pulmonary magnetic resonance angiography and confirmed by digital subtraction pulmonary angiography in a patient where the CT scan was unremarkable.

A rare disease in a female of 60 is reported. Telangiectasias of skin venules, brain, mediastinum, stomach, duodenum and jejunum were found. The disease manifested with repeated massive intestinal bleedings. Elastic fibers alterations were found in the ectatic vessels and surrounding connective tissue.
