In livestock, diarrhea is called scours. There are many causes of diarrhea: bacterial, viral, parasites, and diet. Flystrike risk. Sheep that have diarrhea are more prone to flystrike (blowflies or maggots). To. help prevent flystrike, it is recommended that lambs be docked.
Normal and abnormal blood vessels. In a brain AVM, blood passes directly from arteries to veins via a tangle of abnormal blood vessels. A brain arteriovenous malformation (AVM) is a tangle of abnormal blood vessels connecting arteries and veins in the brain. The arteries are responsible for taking oxygen-rich blood from the heart to the brain. Veins carry the oxygen-depleted blood back to the lungs and heart.
Developmental venous anomaly. Dr Henry Knipe â and Dr Donna D'Souza et al. Developmental venous anomaly (DVA) , also known as cerebral venous angioma, is a congenital malformation of veins which drain normal brain.They were thought to be rare before cross-sectional imaging but are now recognised as being the most common cerebral vascular malformation, accounting for ~55% of all such lesions.WI is the preferred sequence in venous anomalies and proved to have better detectability of venous structures than conventional T2*-weighted imaging. Signals on SWI are not compromised by low-velocity venous flow. Therefore, SWI has successfully demonstrated low-flow vascular formations such as DVA.
