hypertension secondary to renal disease.
hypertension resulting from aortic or renal artery atherosclerosis or from kidney disease, including chronic glomerulonephritis, chronic pyelonephritis, renal carcinoma, and renal calculi. Analgesic abuse and certain drug reactions may also result in renal hypertension. Therapy depends on the cause and may include antibiotics, diuretics, or surgery. Untreated renal hypertension is likely to result in kidney damage and cardiovascular disease.
re·nal hy·per·ten·sion(rēnăl hīpĕr-tenshŭn)
Hypertension secondary to renal disease.
persistently high blood pressure. Detected sporadically in animals partly due to the technical difficulties in diagnosis and the lack of recognizable signs. Greyhounds normally have a higher blood pressure than is found in crossbred dogs with features resembling essential hypertension in humans. Secondary hypertension due to advanced renal disease, hyperthyroidism and hyperadrenocorticism does occur in dogs and cats. Temporary episodes of hypertension occur in all animals suffering severe pain, and in horses with acute laminitis.
that occurring in association with diseases of the endocrine glands.
see Goldblatt kidney.
see rat hypertension (below).
produced experimentally in laboratory animals by the imposition of surgical and psychological insults on the central nervous system.
persistently elevated intraocular pressure in the absence of any other signs of glaucoma; it may or may not progress to chronic simple glaucoma.
abnormally increased pressure in the portal circulation caused by impedance of blood flow through a diseased liver or portal vein.
results from high-pressure blood flow from the right ventricle or impedance to blood flow through the lungs or through the left heart. Chronic hypertension causes endothelial degeneration and fibroplasia of vessel walls. The end result may be cor pulmonale or pulmonary edema. See also altitude sickness, cor pulmonale.
several strains of spontaneously hypertensive rats have been bred.
systemic venous hypertension
elevation of systemic venous pressure, usually detected by inspection of the jugular veins.
