when would a stanford type b require surgery
Aortic dissection The reason for surgical repair of type A dissections is that ascending aortic dissections often involve the aortic valve, which, having lost its suspensory support, telescopes down into the aortic root, resulting in aortic incompetence. The valve must be resuspended in order to be reseated, as well as to repair or prevent coronary artery injury. Also, the area of dissection is removed and replaced with a Dacron graft to prevent further dissection from occurring. However, type B dissections are not improved, from a mortality point of view, by the operation, unless leaking, rupture, or compromise to other organs, e.g. kidneys, occurs.
Medical school A medical school is a tertiary educational institution —or part of such an institution— that teaches medicine, and awards a professional degree for physicians and surgeons. Such medical degrees include the Bachelor of Medicine, Bachelor of Surgery (MBBS, MBChB, BMBS), Doctor of Medicine (MD), or Doctor of Osteopathic Medicine (DO). Many medical schools offer additional degrees, such as a Doctor of Philosophy, Master's degree, a physician assistant program, or other post-secondary education.
