D014650 |
[Blood vessels supplying the nerves.

|
Vasa Previa
|
D055949 |
[Pregnancy complication where fetal blood vessels, normally inside the umbilical cord, are left unprotected and cross FETAL MEMBRANES. It is associated with antepartum bleeding and FETAL DEATH and STILLBIRTH due to exsanguination.

Vasa Vasorum
|
D014651 |
[Nutrient blood vessels which supply the walls of large arteries or veins.

|
Vascular Access Devices
|
D062666 |
[Devices to be inserted into veins or arteries for the purpose of carrying fluids into or from a peripheral or central vascular location. They may include component parts such as catheters, ports, reservoirs, and valves. They may be left in place temporarily for therapeutic or diagnostic purposes.

|
Vascular Calcification
|
D061205 |
[Deposition of calcium into the blood vessel structures. Excessive calcification of the vessels are associated with ATHEROSCLEROTIC PLAQUES formation particularly after MYOCARDIAL INFARCTION (see MONCKEBERG MEDIAL CALCIFIC SCLEROSIS) and chronic kidney diseases which in turn increase VASCULAR STIFFNESS.

|
Vascular Capacitance
|
D018924 |
[The measure of a BLOOD VESSEL's ability to increase the volume of BLOOD it holds without a large increase in BLOOD PRESSURE. The vascular capacitance is equal to the change in volume divided by the change in pressure.

|
Vascular Cell Adhesion Molecule-1
|
D019010 |
[Cytokine-induced cell adhesion molecule present on activated endothelial cells, tissue macrophages, dendritic cells, bone marrow fibroblasts, myoblasts, and myotubes. It is important for the recruitment of leukocytes to sites of inflammation. (From Pigott & Power, The Adhesion Molecule FactsBook, 1993, p154)

Vascular Closure Devices
|
D065506 |
[Products used to seal the openings in BLOOD VESSELS from incisions or punctures made during ENDOVASCULAR PROCEDURES.

|
Vascular Diseases
|
D014652 |
[Pathological processes involving any of the BLOOD VESSELS in the cardiac or peripheral circulation. They include diseases of ARTERIES; VEINS; and rest of the vasculature system in the body.

Vascular Endothelial Growth Factor A
|
D042461 |
[The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.

|
Vascular Endothelial Growth Factor B
|
D042561 |
[A vascular endothelial growth factor expressed in a variety of tissues. It binds with high specificity to VASCULAR ENDOTHELIAL GROWTH FACTOR RECEPTOR-1 and NEUROPILIN-1.
] |
|
Vascular Endothelial Growth Factor C
|
D042582 |
[A vascular endothelial growth factor that specifically binds to VASCULAR ENDOTHELIAL GROWTH FACTOR RECEPTOR-2 and VASCULAR ENDOTHELIAL GROWTH FACTOR RECEPTOR-3. In addition to being an angiogenic factor it can act on LYMPHATIC VESSELS to stimulate LYMPHANGIOGENESIS. It is similar in structure to VASCULAR ENDOTHELIAL GROWTH FACTOR D in that they both contain N- and C-terminal extensions that were not found in other VEGF family members.

|
Vascular Endothelial Growth Factor D
|
D042643 |
[A vascular endothelial growth factor that specifically binds to VASCULAR ENDOTHELIAL GROWTH FACTOR RECEPTOR-2 and VASCULAR ENDOTHELIAL GROWTH FACTOR RECEPTOR-3. In addition to being an angiogenic factor it can act on LYMPHATIC VESSELS to stimulate LYMPHANGIOGENESIS. It is similar in structure to VASCULAR ENDOTHELIAL GROWTH FACTOR C in that they both contain N- and C-terminal extensions that were not found in other VEGF family members.

|
Vascular Endothelial Growth Factor Receptor-1
|
D040281 |
[A 180-kDa VEGF receptor found primarily in endothelial cells that is essential for vasculogenesis and vascular maintenance. It is also known as Flt-1 (fms-like tyrosine kinase receptor-1). A soluble, alternatively spliced isoform of the receptor may serve as a binding protein that regulates the availability of various ligands for VEGF receptor binding and signal transduction.
] |
|
Vascular Endothelial Growth Factor Receptor-2
|
D040301 |
[A 200-230-kDa tyrosine kinase receptor for vascular endothelial growth factors found primarily in endothelial and hematopoietic cells and their precursors. VEGFR-2 is important for vascular and hematopoietic development, and mediates almost all endothelial cell responses to VEGF.
] |
|
Vascular Endothelial Growth Factor Receptor-3
|
D040321 |
[A vascular endothelial cell growth factor receptor whose expression is restricted primarily to adult lymphatic endothelium. VEGFR-3 preferentially binds the vascular endothelial growth factor C and vascular endothelial growth factor D and may be involved in the control of lymphangiogenesis.

|
Vascular Endothelial Growth Factor, Endocrine-Gland-Derived
|
D042662 |
[A vascular endothelial growth factor whose expression is found largely restricted to the GONADS; ADRENAL CORTEX; and PLACENTA. It has similar biological activity to VASCULAR ENDOTHELIAL GROWTH FACTOR-A.
