1/n Basically, if there is an arch aneurysm and a descending aneurysm, it’s pretty hard to get exposure to fix both. So, if you leave an “elephant trunk” behind, it dangles into the descending aneurysm. On return for DTA repair,

First described by Hans Borst in 1983.
#AortaEd 2/n When it’s time to do the descending aorta via left thoracotomy, you can easily clamp the free floating elephant trunk, and stretch it down past the aneurysm. Once the distal anastomosis is sutured in place, the aneurysm is excluded. Simple.

Tweetorial: Just to let everyone know, I wear a mask in the OR for 10 hour cases, with EXTRA CO2 pumping into the sterile field to minimize intracardiac air. I have never once felt the need to take off my mask to breathe. (1/n) Why do we pump CO2? If circulating room air gets in the heart, it’s 78% nitrogen, 21% oxygen, and relatively miniscule amounts of CO2. (2/n)
