Endovascular intervention


The main types of endovascular procedures:

Angiography - x-ray blood vessels (arteries, veins, lymph), indicating narrowing or blockage of the place of the vessel, place and degree of pathological vascular dilatation (aneurysm), the presence of internal bleeding, the extent of tumor and other diseases that are identified by others can not . The study is performed by introducing into the vessel of a special contrast agent, and both of the x-ray studies.

Balloon angioplasty and stenting - the restoration of patency of the narrowed or completely occluded vessels by introducing a special area of ​​narrowing the balloon and inflating it into the lumen of the vessel. In the case of elastic constrictions (after blowing balloon vasoconstriction not eliminated) in the stent lumen is established - a special mesh tube, which creates a framework for the lumen and not giving him a contract in the future. These methods can be applied to all vessels of the human body - head, heart, kidney, upper and lower extremities.

Embolization - blockage of the vessel with special materials and devices (liquid sclerosant, plastic particles, spiral). Such interference is used to stop internal bleeding (gastric, uterine, hemorrhoidal, etc.), stop the blood supply of tumors (hemangiomas, uterine fibroids), abnormal elimination (unwanted) blood flow (varicocele, angiodisplazii, aneurysms, etc.). Embolization is carried out through the catheter into the vessel and allows necessary targeted circulation off from the affected body part or organ without open surgery.

Installing cava filter - a procedure that allows to prevent severe, often fatal complication of venous diseases of lower extremities - pulmonary embolism (blood clot from getting leg veins through the heart to the lungs). In the vena cava through a catheter installed a special device - kavafiltr that captures and holds the torn clots, preventing them from entering the heart and lungs

Drainage and stenting of the biliary tract - with compression of the bile ducts (a scar or a tumor) and the occurrence of jaundice in the biliary tract by puncture of the skin and liver tissue catheter, through which removes stagnant bile. In the blocked portion of the bile duct stent is inserted - special mesh tube that creates a frame within the lumen of the duct and not giving him a contract in the future.

Regional chemotherapy - the introduction of drugs directly into the patient body through a catheter into the appropriate artery. This method of administration compared with the usual intravenous dose of medication can reduce, reduce the number of complications (particularly toxic anticancer drugs), controlled by a gradual recovery process angiographies

Thrombolysis - the introduction of a blood clot that covers the vessel lumen, substances that promote the resorption of the thrombus (thrombolysis). The introduction of thrombolytic therapy is carried out through the catheter directly into the thrombus. This is in many cases to achieve the dissolution of fresh blood clots and prevent the disposal operation
