Veno Health Dictionary

The study of the VEINS, particularly by means of X-rays after the veins have been injected with a radio-opaque substance.... venography

The pressure of blood within the right atrium of the HEART as measured by a catheter and manometer.... central venous pressure

A toxin which usually enters the body by injection through intact skin (e.g. a jellyfish sting or a snake bite bya venomous species).... venom

An abnormal communication between an artery and a vein. It is usually the result of an injury, such as a stab or a gunshot wound, which involves both a neighbouring artery and vein.... arterio-venous aneurysm

Enlarged varicose veins on the cervix of the uterus, often accompanying ulcerations or long-term pelvic congestion. A symptom only of congestion or impaired circulation, they can occur in both semi-trivial and serious conditions.... cervical venosities

An area where there is a buildup of excess venous blood, with enlarged veins and tissue congestion... venosity

Pertaining to the veins, or more broadly to include both venous AND lymphatic circulation.... venous

Having congested venous blood and lymph. Usually a larger condition effecting tissue or organ function, as opposed to the more vascular implications of venosities and varicosities.... venous stasis

See under ULCER.... venous ulcer

The injection of venom by certain animals via their mouthparts (bites) or other injecting apparatus (stings). Venoms are often carried to discourage predators, and are sometimes used to kill or immobilize prey. It is rare for a venomous animal to attack a person unless it has been provoked or disturbed. Specific antivenoms are available to treat many, though not all, types of animal venom. (See also insect stings; jellyfish stings; scorpion stings; snake bites; spider bites.)... venomous bites and stings

a congenital abnormality in which the pulmonary veins enter the right atrium or vena cava instead of draining into the left atrium. The clinical features are those of an *atrial septal defect.... anomalous pulmonary venous drainage

an intravenous catheter for insertion directly into a large vein, most commonly the subclavian vein, during its passage under the clavicle, or the jugular in the neck. Such catheters can also be inserted into the femoral vein at the groin. They enable intravenous drugs and fluids to be given and intravenous pressures to be measured, which is often useful during operations or in intensive care. Central venous catheters must be inserted under strictly sterile conditions using a local anaesthetic.... central venous catheter

the presence of thrombosis in the dural venous sinuses, which drain blood from the brain. Symptoms may include headache, abnormal vision, any of the symptoms of stroke (such as weakness of the face and limbs on one side of the body), and seizures. Treatment is with anticoagulants.... cerebral venous sinus thrombosis

an *ultrasound technique to look for deep vein *thrombosis. Pressing the vein with the ultrasound probe usually causes it to empty and flatten, which does not occur if there is thrombus in the lumen. See also venography.... compression venography

a blood vessel in the fetus that conveys oxygenated blood from the umbilical vein to the inferior vena cava and right atrium, where it passes through the *foramen ovale to the left atrium and left ventricle.... ductus venosus

(JVP) the pressure in the internal jugular vein, which is an indirect measurement of *central venous pressure (CVP) in the right atrium. In clinical practice the JVP is estimated by visual inspection at the bedside with the patient reclining at 45 degrees.... jugular venous pressure

a chamber of the embryonic heart that receives blood from several veins. In the adult heart it becomes part of the right atrium.... sinus venosus

n. the continuous infusion into a vein of saline or other solution.... venoclysis

n. balloon dilatation of a narrowed vein, similar to *angioplasty.... venoplasty

n. see phlebosclerosis.... venosclerosis

(VTE) the formation of a blood clot in a vein, which may become detached and lodged elsewhere. It includes deep vein thrombosis (see phlebothrombosis) and *pulmonary embolism. VTE is a leading direct cause of maternal death (see maternal mortality rate). See also thromboembolism.... venous thromboembolism
