érkatéteres

Érkatéteres refers to a medical procedure involving the insertion of a catheter into a blood vessel. This technique is broadly used in various diagnostic and therapeutic interventions within cardiovascular and interventional radiology fields. The catheter, a thin flexible tube, is guided through the circulatory system to reach a specific target location.

Diagnostic applications include angiography, where contrast dye is injected through the catheter to visualize blood vessels and identify blockages, aneurysms, or other abnormalities. Therapeutic uses are diverse and can involve angioplasty to widen narrowed arteries, stenting to keep vessels open, or delivering medication directly to a particular area, such as chemotherapy drugs to a tumor.

The procedure typically involves a small puncture in a peripheral artery, most commonly in the groin or wrist. Local anesthesia is administered, and guidewires are used to navigate the catheter. Real-time imaging, such as fluoroscopy, is essential for precise catheter placement. While generally safe, potential risks include bleeding, infection, blood clots, or damage to the blood vessel. The recovery time varies depending on the specific procedure performed.
