	Vascular - Wikipedia, the free encyclopedia
		Vascular is an adjective for the word vessel and refers to tube-like structures.
		An organ or tissue that is vascularized is heavily endowed with blood vessels and thus richly supplied with blood.
		Vascular plants include ferns, conifers and flowering plants.

	Catheter with a vascular support - Patent 5405380
		The catheter of claim 1 wherein the proximal end of the vascular support means is fixedly connected to the distal end of the inner catheter and the distal end of the vascular support means is fixedly connected to the proximal portion of the tip.
		Vascular supports of this type fulfill their purpose to the extent that they press the separated, innermost vascular layer, the intima, back against the vascular wall and thus keep the vessel open for flow.
		In order to open vascular support 5 and to release it for use in the relaxed state in which it self-expands, rests against the vascular wall and supports the latter, outer catheter shaft 3 is drawn back with respect to inner catheter 4.

	Angioplasty and Vascular Stenting
		Vascular stenting, which is often performed at the same time as an angioplasty, involves the placement of a small wire mesh tube called a stent in the newly opened artery.
		Renal vascular hypertension is a condition in which one or both of the arteries that supply blood to the kidneys narrow significantly due to atherosclerosis.
		Angioplasty and vascular stenting for peripheral vascular disease (PVD) affecting arteries in the pelvis and legs are less successful when there are multiple leg vessels that are narrowed or when small vessels have to be opened.

	Vascular Access Procedures
		A vascular access catheter is a long, thin tube that is placed in a vein in the arm, in the neck or in the chest just beneath the collarbone.
		Two types of risk are associated with vascular access devices: those occurring during or shortly after placement and delayed risks that occur simply because the device is in your body.
		The procedure of inserting a vascular access device is invasive because incisions are necessary, and the risk of infection must always be kept in mind.

	Involvement of integrin-linked kinase in capillary/tube-like network formation of human vascular endothelial cells
		Angiogenesis is a complex process involving extracellular matrix (ECM) and vascular endothelial cells, and is regulated by various angiogenic factors including vascular endothelial growth factor (VEGF), fibroblast growth factor-2 (FGF-2), interleukin-8 (IL-8), transforming growth factor-α (TGF-α), and others (2, 3).
		The response of vascular endothelial cells to soluble angiogenic factors, as well as interactions between ECM and the cells were required for new blood vessel formation.
		This result indicates that the ability of human vascular endothelial cells to form a capillary/tube-like network in response to VEGF stimulation may not dependent on the type of matrix.

		The AV fistula is considered the best long-term vascular access for hemodialysis because it provides adequate blood flow for dialysis, lasts a long time, and has a complication rate lower than the other access types.
		The tube becomes an artificial vein that can be used repeatedly for needle placement and blood access during hemodialysis.
		A catheter is a tube inserted into a vein in either your neck, chest, or leg near the groin.

		One of the earliest known markers of vascular endothelium is Flk-1, a receptor tyrosine kinase, which is one of two known transmembrane receptors for vascular endothelial growth factor (also known as vascular permeability factor).
		Mutant dorsal aortae maintain a parallel relationship with the mutant neural tube; the vessels bend in the same pattern as the neural tube kinks (Fig 4C).
		The whole-mount identification of vascular endothelium shown in Fig 4 demonstrates the ability of embryos to establish the vascular pattern in the absence of FNs.

	Abstract List
		Both surgically placed ectopic neural tubes and ectopic neural tubes engineered genetically were able to recruit a vascular plexus, showing that the neural tube is the source of a vascular patterning signal.
		Murine neural tube vascular endothelial growth factor A (VEGFA) expression was temporally and spatially correlated with PNVP formation, suggesting it is a component of the neural tube signal.
		Thus, the neural tube is the first structure identified as a midline signaling center for embryonic vascular pattern formation in higher vertebrates, and VEGFA is a necessary component of the neural tube vascular patterning signal.

		The underside of the starfish is covered with hundreds of tube feet, which it uses for walking around, for attaching tightly to rocks, and for holding on to prey.
		This particular posture, with the tip of the ray curled back and the tube feet extended, probably has more to do with smelling than walking, and is very common.

		Tube formation by HUVECs cocultured with Cx43-transfected T98G malignant glioma cells (T98G-Cx43 cells) or with U87MG malignant glioma cells, which naturally express Cx43, was significantly increased compared with tube formation by HUVECs alone.
		The difference in tube formation by HUVECs cocultured with empty vector-transfected T98G glioma cells (T98G-mock cells) or with Cx43-deficient U373MG malignant glioma cells and tube formation by HUVECs alone was not statistically significant.
		Furthermore, the concentration of vascular endothelial growth factor (VEGF), an angiogenic factor important for the induction of angiogenesis and blood vessel formation, was significantly higher in medium harvested from cultures of T98G-Cx43 cells than in that harvested from cultures of control T98G-mock cells.

	VascularWeb: Surgical Bypass
		During a bypass, your vascular surgeon creates a new pathway for blood flow using a graft.
		A graft is a portion of one of your veins or a man-made synthetic tube that your surgeon connects above and below a blockage to allow blood to pass around it.
		During the procedure, your vascular surgeon may perform an arteriogram or duplex ultrasound examination in the operating room to check the bypass for any problems.
