The most common clinical manifestation is spontaneous and recurrent nosebleeds (epistaxis) beginning on average at age 12 years. Telangiectases (small AVMs) are characteristically found on the lips, tongue, buccal and gastrointestinal (GI) mucosa, face, and fingers. The appearance of telangiectases is generally later than epistaxis but may be during childhood. Large AVMs occur most often in the lungs, liver, or brain; complications from bleeding or shunting may be sudden and catastrophic. A minority of individuals with HHT have GI bleeding, which is rarely seen before age 50 years." /><meta name="robots" content="index,nofollow,noarchive" />

The most common clinical manifestation is spontaneous and recurrent nosebleeds (epistaxis) beginning on average at age 12 years. Telangiectases (small AVMs) are characteristically found on the lips, tongue, buccal and gastrointestinal (GI) mucosa, face, and fingers. The appearance of telangiectases is generally later than epistaxis but may be during childhood. Large AVMs occur most often in the lungs, liver, or brain; complications from bleeding or shunting may be sudden and catastrophic. A minority of individuals with HHT have GI bleeding, which is rarely seen before age 50 years. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1351#hht.Summary" target="NBK1351">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Diagnosis" target="NBK1351">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Clinical_Characteristics" target="NBK1351">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Genetically_Related_Allelic_Disorder" target="NBK1351">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Differential_Diagnosis" target="NBK1351">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Management" target="NBK1351">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Genetic_Counseling" target="NBK1351">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Resources" target="NBK1351">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Molecular_Genetics" target="NBK1351">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.Chapter_Notes" target="NBK1351">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1351#hht.References" target="NBK1351">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="spaceAbove">Arteriovenous malformations of the brain are tortuous, morphologically abnormal vascular channels between arteries and veins that lack an intervening capillary network, allowing high-pressure arterial blood from feeding arteries to shunt directly into the venous outflow system. These vascular malformations occur in approximately 15 per 100,000 persons and are a leading cause of hemorrhagic stroke in young adults and children (summary by Nikolaev et al., 2018).</div>

<div class="spaceAbove">Pulmonary arteriovenous malformation, a condition most commonly associated with hereditary hemorrhagic telangiectasia, is an abnormal communication between the pulmonary artery and pulmonary vein without an intervening capillary communication. HRCT images usually show a coarse spidery appearance of the peripheral vascular markings in the lungs. More specific findings are obtained in the pulmonary angiogram where the normally invisible capillary phase is replaced by irregular vascular channels bridging the peripheral branches of pulmonary arteries and veins.</div>

<div class="spaceAbove">A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. It is said to be the third leading cause of death in the United States. Gunel and Lifton (1996) noted that about 20% of strokes are hemorrhagic, resulting in bleeding into the brain. Ischemic strokes, resulting from vascular occlusion, account for the majority of strokes.&#13; Bersano et al. (2008) reviewed genetic polymorphisms that have been implicated in the development of stroke. Candidate genes include those involved in hemostasis (see, e.g., F5; 612309), the renin-angiotensin-aldosterone system (see, e.g., ACE; 106180), homocysteine (see, e.g., MTHFR; 607093), and lipoprotein metabolism (see, e.g., APOE; 107741).&#13; See also hemorrhagic stroke, or intracerebral hemorrhage (ICH; 614519).</div>
