Osler-Weber-Rondu syndrome (Hereditary Hemorrhagic Telangiectasia / HHT) is a rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the skin, mucous membranes, and often in organs such as the lungs, liver, and brain. | |||
Telangiectasia (small vascular malformations) may occur in the skin and mucosal linings of the nose and gastrointestinal tract. | Telangiectasia (small vascular malformations) may occur in the skin and mucosal linings of the nose and gastrointestinal tract. | ||
[[Arteriovenous malformation (AVM)]] is an abnormal connection between arteries and veins, bypassing the capillary system. This vascular anomaly is widely known because of its occurrence in the central nervous system (usually [[Arteriovenous malformation (AVM)]]), but can appear in any location. Although many AVMs are asymptomatic, they can cause intense pain or bleeding or lead to other serious medical problems. | [[Arteriovenous malformation (AVM)]] is an abnormal connection between arteries and veins, bypassing the capillary system.
