Ectasia

 

limited dilatation of the lumen of a hollow organ or blood vessel. Ectasia may be congenital, as in the case of bronchiectasis and telangiectasia. However, the condition occurs more often as a result of stenosis, above which the lumen of a hollow organ dilates. It is treated by surgery.
