The collateral network concept: a reassessment of the anatomy of spinal cord perfusion.
Prevention of paraplegia after repair of thoracoabdominal aortic aneurysm requires understanding the anatomy and physiology of the spinal cord blood supply. Recent laboratory studies and clinical observations suggest that a robust collateral network must exist to explain preservation of spinal cord perfusion when segmental vessels are interrupted. An anatomic study was undertaken. ⋯ The anterior spinal artery is only one component of an extensive paraspinous and intraspinal collateral vascular network. This network provides an anatomic explanation of the physiological resiliency of spinal cord perfusion when segmental arteries are sacrificed during thoracoabdominal aortic aneurysm repair.

Bovine jugular vein valved conduit: up to 10 years follow-up.
The present study evaluated the mortality and conduit failure in bovine jugular vein (BJV) conduits. ⋯ After 10 years of experience with the BJV, this conduit has remained a reliable alternative to pulmonary homografts with respect to survival and freedom from conduit failure. However, the incidence was greater and the presentation of conduit failure was earlier in patients with a smaller size BJV conduit (12-14 mm).
