3.Postoperative outcomes:
Mortality and serious adverse events are summarized in table 3. One
patient had smooth postoperative course without complications. The
patient who had severe aortic insufficiency with coronary and intestinal
malperfusion developed right ventricular dysfunction and required
hemodyalisis post-operatively. He also developed right brachial plexus
palsy with full recovery and totally relieved from intestinal
malperfusion. The other patient with intestinal malperfusion developed
hemorrhagic shock post-operatively with severe abdominal pain. An
exploratory laparotomy revealed a huge hemoperitoneum that was drained.
The patient who had neurological deficit developed multiple small
cerebral emboli due to atrial fibrillation. He also developed
ventilator-associated pneumonia and acute renal insufficiency requiring
hemodialysis. His consciousness improved with time. No aortic
reinterventions were needed. No aortic injury related to the device was
noted. Mortality rate was zero at the post-operative day 30. Patients
were discharged from the hospital after an average of 21 days.
