|
Vascular Headaches
|
D014653 |
[Secondary headache disorders attributed to a variety of cranial or cervical vascular disorders, such as BRAIN ISCHEMIA; INTRACRANIAL HEMORRHAGES; and CENTRAL NERVOUS SYSTEM VASCULAR MALFORMATIONS.
] |
|
Vascular Malformations
|
D054079 |
[A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.

|
Vascular Neoplasms
|
D019043 |
[Neoplasms located in the vasculature system, such as ARTERIES and VEINS. They are differentiated from neoplasms of vascular tissue (NEOPLASMS, VASCULAR TISSUE), such as ANGIOFIBROMA or HEMANGIOMA.

|
Vascular Patency
|
D014654 |
[The degree to which BLOOD VESSELS are not blocked or obstructed.
] |
|
Vascular Remodeling
|
D066253 |
[The active alterations of vascular wall structures, often leading to elevated VASCULAR RESISTANCE. It is associated with AGING; ATHEROSCLEROSIS; DIABETES MELLITUS; HYPERTENSION; PREGNANCY; PULMONARY HYPERTENSION; and STROKE, but is also a normal part of EMBRYOGENESIS.
] |
|
Vascular Resistance
|
D014655 |
[The force that opposes the flow of BLOOD through a vascular bed. It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT.
, The total vascular resistance in the systemic circulation. It is equal to the mean arterial BLOOD PRESSURE minus the CENTRAL VENOUS PRESSURE divided by CARDIAC OUTPUT.
] |
|
Vascular Ring
|
D000073872 |
[Congenital vascular malformation in which the AORTA arch and its branches encircle the TRACHEA and ESOPHAGUS. Signs and symptoms include DYSPNEA; RESPIRATORY SOUNDS, especially with eating, DYSPHAGIA, persistent cough, and GASTROESOPHAGEAL REFLUX or may be asymptomatic. Two most common types are double aortic arch and right aortic arch. It may be associated with other anomalies (e.g., DIGEORGE SYNDROME).
] |
|
Vascular Stiffness
|
D059289 |
[Loss of vascular ELASTICITY due to factors such as AGING; and ARTERIOSCLEROSIS. Increased arterial stiffness is one of the RISK FACTORS for many CARDIOVASCULAR DISEASES.
] |
|
Vascular Surgical Procedures
|
D014656 |
[Operative procedures for the treatment of vascular disorders.
] |
|
Vascular System Injuries
|
D057772 |
[Injuries to blood vessels caused by laceration, contusion, puncture, or crush and other types of injuries. Symptoms vary by site and mode of injuries and may include bleeding, bruising, swelling, pain, and numbness. It does not include injuries secondary to pathologic function or diseases such as ATHEROSCLEROSIS.
] |
|
Vascularized Composite Allotransplantation
|
D063986 |
[Transference of multiple tissues, such as muscle, bone, nerve, and skin, as a functional unit for reconstructive purposes. Blood supply to the transplanted tissues is maintained throughout the transplantation procedure with minimal ischemia. Maintenance of vascularity in the graft promotes its viability, function, and survival in the recipient.

|
Vasculitis
|
D014657 |
[Inflammation of any one of the blood vessels, including the ARTERIES; VEINS; and rest of the vasculature system in the body.
] |
|
Vasculitis, Central Nervous System
|
D020293 |
[Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)

|
Vasculitis, Leukocytoclastic, Cutaneous
|
D018366 |
[Disorder characterized by a vasculitic syndrome associated with exposure to an antigen such as a drug, infectious agent, or other foreign or endogenous substance. Its pathophysiology includes immune complex deposition and a wide range of skin lesions. Hypersensitivity or allergy is present in some but not all cases.
] |
|
Vasectomy
|
D014659 |
[Surgical removal of the ductus deferens, or a portion of it. It is done in association with prostatectomy, or to induce infertility. (Dorland, 28th ed)
] |
|
Vasoactive Intestinal Peptide
|
D014660 |
[A highly basic, 28 amino acid neuropeptide released from intestinal mucosa. It has a wide range of biological actions affecting the cardiovascular, gastrointestinal, and respiratory systems and is neuroprotective. It binds special receptors (RECEPTORS, VASOACTIVE INTESTINAL PEPTIDE).
] |
|
Vasoconstriction
|
D014661 |
[The physiological narrowing of BLOOD VESSELS by contraction of the VASCULAR SMOOTH MUSCLE.
