Within affected vessels, the internal elastic membrane was often fragmented, and the subintimal
space and smooth muscle of the tunica media were disorganized and replaced by atherosclerotic material composed of large foamy cells, fat, and cholesterol deposits, and occasional chondroid metaplasia and mineral deposition.
Once the catheter has passed the blockage, a unique conical-shaped positioning balloon is used to expand the subintimal
space and direct a micro-catheter lancet to re-enter the vessel.
7) On coronary angiography, an intimal tear is usually evidenced by contrast staining in the subintimal
space while bleeding in the microvasculature within the arterial wall appears as an abrupt change in vessel caliber that does not improve with the administration of intracoronary vasodilating medications.
The pathology underlying restenosis is complex, involving a multitude of processes (inflammatory response to endothelial denudation and subintimal
hemorrhage triggered by angioplasty followed by vascular smooth muscle cell proliferation and migration, extracellular matrix formation, and vascular remodeling) (3).
Over time, accretion of more cholesterol, calcium, and cellular detritus results in a discrete volume of occlusive plaque, subintimal
Development of atherosclerosis is a complicated chain of events starting with accumulation of LDL cholesterol in the subintimal
enjeksiyon veya arteriyel tromboz durumlarinda da beyin kan akimi olmadigi goruleceginden yaniltici olur.
edema and cytoplasmic mitochondrial swelling was also detected in UC group.
Combined primary subintimal
and endoluminal angioplasty for ischaemic inferior limb ulcers in diabetic patients: 5 year practice in a multi disciplinary 'diabetic-foot' service.
The blunt tip CrossBoss Catheter utilizes the Fast-Spin technique to facilitate crossing of CTOs along true lumen or subintimal
A team of interventional cardiology experts at the hospital this week successfully treated the first patient who underwent the new procedure called Controlled Antegrade and Retrograde Subintimal
Tracking (CART) which saw the hospital adopting the oretrograde approach in angioplastyo for the first time.
45) In reviewing the role of the adventitia in vascular function, Gutterman (46) concluded that adventitial fibroblasts may actively participate in preatherosclerotic subintimal
proliferation, give rise to calcium deposition in chronic atherosclerotic lesions, and help transmit neurogenic signals when endothelial function is reduced.
