Cavography Upper

Cavography is a study that allows you to evaluate the condition of the veins and large blood vessels located in the chest and upper half of the body. It is carried out using a special device that is connected to the vessels using a catheter. A catheter is a thin, flexible tube through which contrast agents are injected. During the examination, they pass through the veins and arteries, allowing the doctor to see their anatomical structure.

Cavography is a method for studying arterial and venous blood flow in the coronary system and brain using radiopaque agents administered intravenously or inhaled in the presence of cardiovascular pathology. The study is carried out using special equipment - a carotid probe.

Cavography is divided into three types: upper (cavography superior), lower (cavography inferior) and middle, which is used to detect valve defects between the caroid sinus and the left common carotid artery.

Introduction

Cavography is a method for studying the vascular system of the brain. This method is based on the use of X-rays to assess the state of the venous system of the brain and identify possible anomalies in its functioning. Cavography of the superior cavity is used to determine the condition of the superior cavernous system, which is part of the superior vena cava system. In this material we will consider the topic of Upper Kaverna cavography, the features of diagnosing this pathology and methods of its treatment.

Description of the method

For superior cavity cavography, it is necessary to make a small incision in the neck, which allows access to the superior cavernous veins. During the procedure, X-rays are directed through the vena cava into the brain, which allows for good visualization of its structures. Particular attention is paid to the condition of the vein of Galen and its branches. If any abnormalities are detected, the doctor may suggest additional tests, such as a CT scan or MRI.

Causes of the disease

Cavernous genital disease occurs due to a violation of the outflow of blood from the brain due to the formation of blood clots and the closure of the natural lumen of the veins. Also increased venous pressure, previous stroke. Canography of the inferior hollow system is carried out for differentiation and when carrying out specific treatment, for example, prescribing
