Arterial Tortuosity Syndrome (ATS) is a rare genetic condition that is characterized by arteries that are too long which twist and kink. ATS may predispose a person to stroke, heart attack, aneurism, and general pain. This connective tissue syndrome can also cause joints to stretch further than their normal range and predispose an affected individual to abdominal hernias. There are currently only 100 cases of ATS documented. ATS runs in families. ATS is commonly misdiagnosed or diagnosed at a late stage. There is currently no treatment for ATS, although other risk factors for stroke and heart attack, such as high blood pressure or obesity, can be controlled to decrease a persons overall risk of this complications.
