Selective antegrade cerebral perfusion during aortic arch surgery confers survival and neuroprotective advantages.
Summary of "Selective antegrade cerebral perfusion during aortic arch surgery confers survival and neuroprotective advantages."
To assess the impact of using antegrade cerebral perfusion during aortic arch surgery on postoperative survival and neurologic outcomes.
All operations were performed at the same hospital between January 2001 and January 2009. Patients undergoing aortic arch surgery using antegrade cerebral perfusion during deep hypothermia were compared with patients undergoing aortic arch surgery without antegrade cerebral perfusion during the same study period. Multivariable logistic regression and Cox proportional hazards model were used to identify predictors of postoperative cerebrovascular accidents and midterm survival, respectively. There were 46 patients in the antegrade cerebral perfusion group and 78 patients in the non-antegrade cerebral perfusion group.
There were no statistically significant differences in age, proportion of emergency operations, or proportion of type A aortic dissection between the 2 groups. There was a statistically significant and clinically important difference in the rates of postoperative cerebrovascular complications (2% antegrade cerebral perfusion vs 13% non-antegrade cerebral perfusion, P = .03), postoperative duration of mechanical ventilation (1.15 +/- 0.19 days antegrade cerebral perfusion vs 2.13 +/- 0.38 days non-antegrade cerebral perfusion, P = .02), and 3-year survival (93% antegrade cerebral perfusion vs 78% non-antegrade cerebral perfusion, P = .03). Antegrade cerebral perfusion was shown to be a significant predictor of reduced postoperative stroke rates and better survival at 3 years.
Antegrade cerebral perfusion was associated with improved survival and neurologic outcomes in patients undergoing aortic arch surgery, especially for cases requiring prolonged aortic arch repair periods.

Medical and Biotech [MESH] Definitions
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
Intra-aortic Balloon Pumping
Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.
The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.
Degeneration of white matter adjacent to the CEREBRAL VENTRICLES following cerebral hypoxia or BRAIN ISCHEMIA in neonates. The condition primarily affects white matter in the perfusion zone between superficial and deep branches of the MIDDLE CEREBRAL ARTERY. Clinical manifestations include VISION DISORDERS; CEREBRAL PALSY; PARAPLEGIA; SEIZURES; and cognitive disorders.
