érkatéterezések

Érkatéterezések, commonly referred to as catheterization of blood vessels, involve the insertion of a thin, flexible tube called a catheter into a blood vessel. This procedure is a cornerstone of modern interventional medicine, enabling a wide range of diagnostic and therapeutic interventions. The catheter is typically guided to a specific location within the circulatory system using real-time imaging techniques such as fluoroscopy.

Diagnostic applications of érkatéterezések include angiography, where contrast dye is injected through the catheter to visualize blood flow, identify blockages, aneurysms, or other abnormalities. This helps physicians pinpoint the exact nature and location of vascular problems.

Therapeutic uses are extensive and continually evolving. Catheters can be used to deliver medications directly to a targeted area, such as chemotherapy drugs to a tumor or thrombolytic agents to dissolve blood clots. They are also employed in angioplasty, where a balloon at the tip of the catheter is inflated to widen narrowed or blocked arteries. Stents, small mesh tubes, are often deployed to keep these vessels open after angioplasty. Other procedures include valve repair or replacement, removal of blood clots, and embolization, which involves blocking off abnormal blood vessels.

Érkatéterezések are generally considered minimally invasive compared to traditional open surgery, leading to shorter recovery times and reduced risks for patients. However, as with any medical procedure, potential complications can occur, including bleeding, infection, damage to the blood vessel, or reactions to contrast dye. The decision to proceed with catheterization is made after careful evaluation of the patient's condition and potential benefits versus risks.
