What SVC means?

Switched Virtual Circuit
(1) (Switched Virtual Circuit) A network connection that is established at the time the transmission is required and disconnected when the session is completed. SVCs are normally implemented in connection-oriented systems such as the analog telephone network and ATM networks.

What is the meaning of SVC and IVC?

After circulating through the body systemically, deoxygenated blood returns to the right atrium of the heart through either the SVC, which drains the upper body, or the inferior vena cava (IVC) that drains everything below the diaphragm.

What does Surgical SVC stand for?

SVC obstruction is a narrowing or blockage of the superior vena cava (SVC), which is the second largest vein in the human body. The superior vena cava moves blood from the upper half of the body to the heart.

How is SVC syndrome diagnosed?

Although SVC syndrome is a clinical diagnosis, plain radiography, computed tomography (CT) and venography are used for confirmation (1). Recommended treatments for cancer-related SVC syndrome include chemotherapy and radiation to reduce the tumour that is causing the obstruction.

What is SVC in energy?

A static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the Flexible AC transmission system device family, regulating voltage, power factor, harmonics and stabilizing the system.

What is SVC vein?

The superior vena cava (SVC) is a large, valveless vein that conveys venous blood from the upper half of the body and returns it to the right atrium. In this article, we will look at the anatomy of the superior vena cava – its position, tributaries, and clinical correlations.

What is an IVC in medical terms?

An inferior vena cava (IVC) filter is a small device that can stop blood clots from going up into the lungs. The inferior vena cava is a large vein in the middle of your body. Veins are the blood vessels that bring oxygen-poor blood and waste products back to the heart.

How can you tell the difference between SVC and IVC obstruction?

The most common symptoms of SVC obstruction are headache, shortness of breath (SOB), facial plethora, upper limb edema, and distended neck and upper chest veins [2]. IVC obstruction commonly presents with lower limb edema, tachycardia, and supine hypotensive syndrome [3].

What happens when the vena cava is blocked?

A blockage in the inferior vena cava (IVC) can lead to chronic leg swelling, pain, and immobility, according to the University of California Los Angeles (UCLA) IVC Filter Clinic. There may be other health complications depending on a person’s age and preexisting medical conditions.

How do you treat SVC syndrome?

The main treatment for SVCS is to treat the cancer that is causing it with chemotherapy or radiotherapy. However, other things can be done to alleviate the symptoms. Your doctor might prescribe corticosteroids to reduce swelling or diuretics to remove excess fluid from your body by increasing urination.

What is the most common cause of SVC syndrome?

The most common cause of superior vena cava syndrome is cancer. Primary or metastatic cancer in the upper lobe of the right lung can compress the superior vena cava. Lymphoma or other tumors located in the mediastinum can also cause compression of the superior vena cava.

What is SVC medical term?

SVC syndrome . Superior vena cava (SVC) syndrome. A condition seen in lung cancer patients where the tumor presses against a large blood vessel and causes various symptoms.

What does SVC stand for?

SVC also stands for supervisor call. In a network, a switched virtual circuit (SVC) is a temporary virtual circuit that is established and maintained only for the duration of a data transfer session. A permanent virtual circuit (PVC) is a continuously dedicated virtual circuit.

What is SVC syndrome?

Jump to navigation Jump to search. Superior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava (“SVC”), a short, wide vessel carrying circulating blood into the heart.
