Abstract:
Patient factors can present formidable challenges in emergent aortic surgery. We report successful mechanical aortic root, ascending aorta, and Zone 2 arch replacement under hypothermic circulatory arrest in a 305 kg patient with acute type A aortic dissection. A dual-oxygenator bypass circuit, proactive metabolic management, bilateral fasciotomies, and early renal replacement therapy were critical to a favorable outcome.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
