摘要

Hereditary hemorrhagic telangiectasia (HHT; HEM-or-RAJ-ick tell-AN-jee-eck-TAY-zhuh) is a genetic disorder of the blood vessels. It is also called Osler-Weber-Rendu disease. People with HHT have abnormal blood vessels that tend to burst open and bleed.HHT affects men and women from all racial and ethnic groups. The abnormal gene comes from one parent who has HHT. If a parent has HHT, his or her children have a 50 percent chance of inheriting the gene and developing HHT. It is possible to have HHT with symptoms so mild that you don't notice them.
