At last follow-up, she had saturations in the high 90’s, though her atrial communication continued to shunt right-to-left as a result of restrictive RV physiology.

Nor did this appear to be severe pulmonary hypertension secondary to a left-to-right shunt. Thus ... explanation for the variability of physiologic response to hypoventilation with hypoxia ...

Brain arteriovenous malformations (BAVMs) are fragile tangles of malformed vasculature characterized by arteries and drained by veins without intervening capillaries that are formed from a high-flow, ...

Stage 1 palliation, whether with a classical Norwood operation or with the conduit modification, is a complex procedure, which imposes profound physiological changes ... the bi-directional ...

Save the Lactate Shunt. Astrocytes normally feed lactate to neurons (left). This dries up when Aβ or tau oligomers activate IDO1, causing a flood of kynurenine that suppresses astrocyte glycolysis ...

In addition, in 1 patient, samples of thoracic-duct lymph were collected during a portacaval-shunt operation. All specimens were ten-minute samples of lymph, and volumes were recorded. Sodium was ...
