These changes included dilation and atheromas of elastic pulmonary arteries, medial hypertrophy, and eccentric intimal thickening in small arteries and arterioles
To test this possibility, we also selected arterioles
and venules between the superior and inferior vessel arches to analyze the oxygen saturation around the macular area.
By the m-IVAN method, we found a statistically significant decrease in vessel diameters in macular arterioles
and venules after laser treatment (MRAE 73.5 [micro]m versus 72.0 [micro]m, p = 0.04, and MRVE 63.5 [micro]m versus 62.4 [micro]m, p = 0.02, resp.).
The lobe of each RERM had the aspect of a ball of arteries and arterioles
. In a second step, it was isolated from its connections with the distal part of the internal carotid artery, then cut in a few millimeters segments, as linearly as possible.
Originally, it was thought appropriate to quantify generalised arteriolar attenuation due to evidence that arterioles
would be more affected by narrowing in response to cardiovascular disease processes than venules.
Hypertension induces spasm, stiffening, and remodeling of resistance vessels, which results in autoregulatory dysfunction in brain arterioles
On fundus examination, calcific embolus was noted with inferotemporal BRAO and narrowed arterioles
with partial macular edema in the right eye (Figure 1).
Thrombotic microangiopathy, or TMA, is a condition where a blood clot occurs in capillaries and arterioles
due to an endothelial injury.
Summary: Nephrosclerosis is the hardening of the walls of small arteries and arterioles
of the kidney.
A: At the glomerulus, the blood is filtered --about 20 per cent of the plasma volume exits the renal arterioles
into the Bowman's capsule.
The renal corpuscles have numerous tortuous arterioles
covered by podocytes, where the whole endothelial layer of these arterioles
, their basement membrane and the podocytes correspond to the glomerular filtration barrier (Bloom & Fawcett, 1975; Jarad & Miner, 2009).
The middle layers of preacinar arterioles
measuring 30-60 pm in diameter were measured.
This smooth muscle relaxation causes the dilatation of blood vessels that suppresses vascular resistance and optimizes tissue perfusion, including that in the arterioles
Calciphylaxis or calcific uremic arteriolopathy (CUA) is a rare and severe disorder characterized by systemic medial calcification of arteries and arterioles
that leads to skin and soft tissues ischemic necrosis with the development of ulcers (1).
The main renal artery, intrarenal arteries and arterioles
, and glomerular capillaries, and renal vein can be involved; thrombotic lesions and glomerulonephritis (GN) have also been identified in primary APS (2).
