Using multiple wiring techniques, access to the popliteal artery was obtained with the guidewire to the subintimal or true lumen, and balloon dilatation (2 mm or 2.5 mm) was applied to the proximal segment of the occluded artery.
These include retrograde wiring through collateral channels and both antegrade and retrograde subintimal dissection and reentry techniques.
In the early stages, the subintimal part of the central and sublobular venula thickens due to edema.
(2-4) The pathogenesis of DA involves an arterial wall tear that leads to subintimal hematoma resulting in luminal narrowing, occlusion, aneurysmal dilatation, or vascular rupture.
Vertebral artery dissection occurs with the rending of subintimal or subadventitial tissue layers in the vessel wall and the subsequent entry of blood in the tissue range; as a result, blood flow in the vessel lumen is disrupted (1, 2).
In this context, the authors were able to show that following a perfusion period of eight hours with gassed Tyrode solution and sodium carboxymethyl cellulose, the intimal layer of the equine fetlock joint capsule appeared unchanged whereas the subintimal connective tissue presented mild signs of edema.
Atherosclerosis is a systemic chronic inflammatory disease predominantly affecting muscular and elastic arteries, characterized by autoimmune response to arterial wall damaging with development of subintimal accumulation of lipids, immunocompetent cells, and smooth muscle cells [1].
[7] wall of the fetal anemia, and umbilical vein with severe HIE/AS 3 at 1, discontinuity in the 5, and 10 min layers of the Follow-up at the subintimal and age of 4 years: internal elastic spastic tetraplegia, lamina.
As the patient was clinically unstable and rapidly deteriorating, we initially opted not to perform further assessment with an intravascular ultrasound (IVUS) and quickly treat the haematoma with an additional stent implantation, but after deploying a 2.5 x 18 mm Orsiro (BIOTRONIK) DES, the subintimal haematoma was propagated more distally with further subtotal occlusion of the vessel (Figure 2(b)).
Artery dissection of the carotid arteries occurs when a tear arises in the intima or the media of the arterial wall, resulting in the formation of intramural hematoma in the subintimal, medial, and subadventitial layers leading to narrowing (stenosis) or complete occlusion [11-13].
Intentional subintimal access was achieved using either a hydrophilic 0.035 inch wire or a 0.018 inch guidewire.
In addition, the tumor subsequently invaded the subintimal layer of the pulmonary trunk wall reaching the pulmonary valve.
