Know About Peripheral Vascular Diseases

Renal disorder is more likely to occur in a patient with hypertension. The patient has a reduced renal reserve but no signs of renal failure in stage I renal disease. If left untreated, the condition will progress to stage II renal disease, which causes renal insufficiency in the patient. He’ll have lost more than 75% of his glomerular function and will start to show signs of renal disease including anaemia and moderate hyperkalemia. Uncontrolled hypertension can progress to stage III, end-stage renal disease, which can lead to chronic renal failure.You may want to check out this website for more.

Blood enters the glomerulus under high pressure due to increased vascular resistance of the sclerosed arteries in hypertension, destroying the glomerular membrane. The tubules die as a result of the affected membrane’s inability to filter selectively.

Hypertension also disrupts the renin-angiotensin-aldosterone pathway, causing ischemia and a decrease in blood flow to the kidneys. In an effort to increase the glomerular filtration rate, water and sodium reabsorption are increased, resulting in volume overload and higher vascular pressure, which causes glomerular sclerosis.

Segmental pressure scales, anklebrachial indices, and pulse volume recordings are all noninvasive measures for peripheral vascular disease.

Blood pressure cuffs are placed on the thigh, directly above the knee, directly below the knee, and at the ankle for a segmental pressure measurement. The pressure cuffs are then inflated one by one. The patient may have severe lesions if systolic pressure drops by 15% or more from one site to another.

An exercise stress examination, as well as an anklebrachial index and pulse volume recording, can be ordered by a physician. The patient exercises until he experiences severe claudication during the exam. After that, an anklebrachial index is determined by taking systolic blood pressures in both the ankle and the arm at the same time. During low-level exercise, severe claudication produces a major difference in ankle and brachial blood pressures.
