  2. Renal artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Renal_artery_stenosis

    Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia. This narrowing of the renal artery can impede blood flow to the target kidney , resulting in renovascular hypertension – a secondary type of high blood pressure .

  3. Atheroma - Wikipedia

    en.wikipedia.org/wiki/Atheroma

    Atheroma within aneurysmal enlargement (vessel bulging) can also rupture and shower debris of atheroma and clot downstream. If the arterial enlargement continues to 2 to 3 times the usual diameter, the walls often become weak enough that with just the stress of the pulse, a loss of wall integrity may occur leading to sudden hemorrhage (bleeding ...

  4. Atherosclerosis - Wikipedia

    en.wikipedia.org/wiki/Atherosclerosis

    As long as the artery enlarges sufficiently to compensate for the extra thickness of the atheroma, then no narrowing ("stenosis") of the opening ("lumen") occurs. The artery expands with an egg-shaped cross-section, still with a circular opening. If the enlargement is beyond proportion to the atheroma thickness, then an aneurysm is created. [71]

  5. Vulnerable plaque - Wikipedia

    en.wikipedia.org/wiki/Vulnerable_plaque

    Generally an atheroma becomes vulnerable if it grows more rapidly and has a thin cover separating it from the bloodstream inside the arterial lumen. Tearing of the cover is called plaque rupture . However, a repeated atheroma rupture and healing is one of the mechanisms, perhaps the dominant one, that creates artery stenosis .

  6. Kidney - Wikipedia

    en.wikipedia.org/wiki/Kidney

    The removal of kidney stones involves ultrasound treatment to break up the stones into smaller pieces, which are then passed through the urinary tract. One common symptom of kidney stones is a sharp to disabling pain in the middle and sides of the lower back or groin.

  7. Renal vein thrombosis - Wikipedia

    en.wikipedia.org/wiki/Renal_vein_thrombosis

    Surgery to remove the clot is possible, but rarely performed. In the past, surgical removal of the renal vein clot was the primary treatment but it is very invasive and many complications can occur. In the past decades, treatment has shifted its focus from surgical intervention to medical treatments that include intravenous and oral ...
