AORTIC DISSECTION
history and definitions:
Definition:
Aortic Dissection (AD) occurs with an intimal tear that allows redirection of blood from from the aorta (true lumen) through this defect into the aortic media creating a false lumen and a dissection plane that separates the aortic intima from the overlying aortic adventitia

History:
- Sennertus was the first to describe the dissection process.
- Maunoir named this process Aortic dissection.
- Laennec defined the tendency of chronically dissected aorta to become aneurysmal.
- Gurin performed the first aortic fenestration procedure to treat malperfusion syndrome.
- Abbot and Paulin used cellophane wrapping of the aorta to theoretically prevent aortic rupture.
- DeBakey successfully performed primary surgical repair of aortic dissection.
