1 Emergency cannulation for proximal perfusion in descending thoracic aorta procedures 
Eugenio Neri, MD, Gianni Capannini, MD, Enrico Carone, MD, Enrico Tucci, MD, Carlo Sassi, MD  The Annals of Thoracic Surgery  Volume 68, Issue 2, Pages (August 1999) DOI: /S (99)00613-X

2 Fig 1 Circuit of cardiopulmonary bypass (CPB) with the safety cannula inserted on a side branch of the arterial line. The Annals of Thoracic Surgery  , DOI: ( /S (99)00613-X)

3 Fig 2 The aneurysm of the descending thoracic aorta is open and the proximal anastomosis is begun. Distal perfusion is assured by the pump oxygenator, and proximal perfusion is assured by the heart; in the event of an acute cardiac failure or arrest in this phase of the operation, rapid conversion to an integral assisted circulation may be obtained with the aid of the safety cannula. The Annals of Thoracic Surgery  , DOI: ( /S (99)00613-X)

4 Fig 3 The cannula is inserted inside the lumen of the aorta, with the balloon half inflated, sliding the fingers that control the aorta, after the removal of the clamp. To facilitate the anastomosis, the cannula is first passed inside the prosthesis and then slid inside the aorta. The Annals of Thoracic Surgery  , DOI: ( /S (99)00613-X)

5 Fig 4 Proximal assistance is instituted. The presence of the arterial line across the site of the anastomosis is not excessively bothersome for suturing. The cannula is very stable inside of the aorta because of the large contact surface of the balloon. The Annals of Thoracic Surgery  , DOI: ( /S (99)00613-X)
