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.
Renovascular hypertension is as likely to occur with bilateral stenosis (when arteries to both kidneys are narrowed) as with unilateral stenosis (when the artery to one kidney is narrowed). The decreased blood flow to the kidneys impairs renal function.Renal artery stenosis may cause renal failure in some patients.There is no predictable relationship between renal failure and renal artery stenosis. Some patients have very severe bilateral stenosis and normal renal function.he decreased blood flow to the kidneys impairs renal function. Renal artery stenosis may cause renal failure in some patients. There is no predictable relationship between renal failure and renal artery stenosis.
