Intravenous (vascular) interventional radiological procedures
Vascular methods include interventions on both arteries (arteries) and veins (veins). In general, diseases involving all veins in the body, except for the arteries and veins of the heart (coronary arteries and veins), can be treated with these methods.
Vascular interventional procedures are procedures performed for both arterial (arterial) and vein (vein) diseases in all body parts except the heart, accompanied by angiography. Diagnostic or therapeutic angiographic procedures can be performed on many organs such as the brain, neck, kidney, liver, stomach, intestine, uterus, prostate, arm and leg.
The main angiographic procedures performed in the Radiology Clinic Angiography Unit of our hospital:
Diagnostic angiography: With this method, the desired artery or vein in the body is reached by entering the vein mostly from the groin, and it is visualized by giving contrast material. Thus, it is revealed what vascular disease is.
Balloon angioplasty/stenting: The method of widening stenosis or obstruction in the vessel with the help of a balloon is called 'balloon angioplasty'. Stenosis or occlusions can be treated in addition to balloon angioplasty or with stenting only (metal cage) method. Which treatment method will be chosen depends on the characteristics of the stenosis/occlusion and the vessel in which it is located. With balloon angioplasty and stenting methods, it is possible to treat stenosis / occlusion of the vessels in many regions and organs such as the brain, arm, leg, kidney, intestine.
Thrombolysis and thrombectomy: The process of reaching the clot in the artery or vein through the vein and dissolving it with the help of medication is called 'thrombolysis', and the process of removing it with the help of some devices is called 'thrombectomy'. Thanks to thrombolysis and thrombectomy procedures, it is aimed to restore the blood supply of the organs, reducing the damage and preserving their functions. These treatments can be life-saving in the occlusion of the brain and intestinal vessels or the portal vein (large vein of the liver) with a clot.
Fistula treatments, dialysis catheter and chemotherapy port placement: In cases where dialysis is required, temporary or permanent dialysis catheter can be placed into the venous system. In patients with dialysis fistula, patency can be restored by applying angiographic treatments in the stenosis/occlusion of the fistula. In patients who will undergo chemotherapy, the chemotherapy port can be placed with imaging methods.
Vena cava filter placement: The clot formed in the deep veins of the legs may break off and go to the pulmonary arteries (arteries of the lung) and block it (pulmonary embolism), which can cause life-threatening. In patients at risk of pulmonary embolism, a filter (umbrella) is placed in the inferior vena cava (main vein of the body). While the filter allows blood flow, it traps clots and prevents them from going to the lungs.
Embolization: Embolization is the process of occlusion of abnormal vascularity by reaching it from within the vessel.
Aneurysm treatment: The process of occlusion of aneurysms (bubbles) in the vessel through the vessel is called 'aneurysm treatment'. This process can be done with different occlusive materials. In this way, it is possible to treat aneurysms without surgical procedures.
Vascular malformation and hemangioma treatment: Vascular tangles, which are congenital or formed after various reasons such as trauma and surgical procedures, can be treated with intravascular or extravascular methods, mostly in a few sessions.
Arteriovenous fistula treatments: Unwanted shortcuts (fistula) between arteries and veins can cause significant circulatory and nutritional disorders. Arteriovenous fistulas can be treated using special occlusive agents.
Tumor embolization: Benign or malignant tumors in many parts of the body can be treated angiographically. By reaching the artery feeding the mass, occlusion is applied with some special materials and the mass is reduced/disappeared.
Transarterial chemoembolization (TAKE): This procedure is frequently applied especially in liver tumors and metastases. The mixture formed by loading the chemotherapy drug on the occlusive microparticles is given to the artery feeding the tumor. In this way, the tumor is prevented from feeding by occlusion of the artery and effective local chemotherapy is applied to the tumor. Since it is local chemotherapy, side effects related to chemotherapy have decreased.
Transarterial radioembolization (TARE): It is applied in the treatment of primary tumors and metastases of the liver, by intravenous administration of the radioactive substance (yttrium 90) loaded on microparticles to the region of the tumor. With the radiotherapy effect of the radioactive substance, the tumor shrinks.
Fibroid embolization: Fibroids formed in the uterus are treated by occlusion by reaching the uterine artery that feeds the fibroid through the vessel. As a result of the procedure, it is seen that the fibroids that occlude the feeding artery shrink, and complaints such as pain and bleeding decrease or disappear.
