Abigail Haynes, an 18-month-old girl who lives near Dahlonega, is traveling to New York City next week to receive her fifth treatment for a rare and worsening vascular disorder. Born with venous malformations, Abigail has undergone four treatments to deal with her unusually thin vein walls, which tend to grow into lesions. The lesions can cause pain, disfigurement and possibly impede or damage important bodily functions such as breathing.
