Prefixes are key morphemes in English vocabulary that begin words. The prefix con-, which means âwithâ or âthoroughly,â appears in numerous English vocabulary words, for example: connect, consensus, and conclude. An easy way to remember that the prefix con means âwithâ is through the word connect, or join âwith.â A way to remember that it means âthoroughlyâ is through conclude, or âthoroughlyâ close a matter.
Vascular surgery. Vascular surgery is a surgical subspecialty in which diseases of the vascular system, or arteries, veins and lymphatic circulation, are managed by medical therapy, minimally-invasive catheter procedures, and surgical reconstruction.
There are several newer, less invasive techniques for bypass surgery that can be used instead of open-chest surgery in some cases. In some procedures, the heart is slowed with medicine but is still beating during the procedure. For these types of surgery, a heart-lung bypass machine is not needed. (For open-chest surgery, a heart-lung machine is needed to circulate the blood and to add oxygen to it.) Other techniques use keyhole procedures or minimally invasive procedures instead of open-chest surgery.
