SCTS Annual Meeting 2022 Abstracts

BackgroundThoraco Abdominal Aortic Aneurysm (TAAA) is rare, occurring in approximately 6-10 per every 100,000 people.But surgical correction of this pathology possesses serious complications like paraplegia and spinal cord problems.The overall 30-day mortality and paraplegia results are 8.5% and 4.2% respectively. Methods BetweenJan 2019 & Sept 2021 we have performed about 12 Thoraco Abdominal Aortic Aneurysm cases and our perfusion techniques for this type of surgery provides good clinical practice and prevents the neuro, spinal cord, gut and renal related complications.All the 12 cases are retrospectively analysed in detail for perfusion techniques, neurological outcome, renal function and the post-operative outcome.Operative technique CPB established with cannulation on PA, RA and Descending Aorta or Femoral venous and Descending Aorta.The surgery was performed at 26 °C and Systemic Potassium was administered into the venous reservoir to arrest the heart.Retrograde cerebral perfusion was performed through the Long Femoral venous cannula.Once the Proximal anastomosis is done under RCP, the upper body flow is established by the sidearm of the anteflo graft.The abdominal vessels are perfused by Silicon catheter.The abdominal vessels and renal arteries are anastomosed one after another to the arms of coselli graft.We perfused the renal arteries with renoplegia every 10 min in each renal artery.Once the descending aorta is anastomosed the clamp is removed and rewarmed to 36 °C.Hemostasis secured and came off CPB uneventfully. ResultsThere was no incidence of any neurological deficit in the post-operative period for all the 12 Patients.Two patients required tracheostomy in the post-operative phase.The Sr. Creatinine was in the desirable range and there was no gut ischemia in the post-operative period. ConclusionOur strategic planning of perfusion techniques for the Thoraco Abdominal Aortic Aneurysm cases resulted in yielding favorable outcome.
