emboliseerimisvahendi

Emboliseerimisvahendid are substances used in medical procedures to intentionally block blood vessels. This technique, known as embolization, is employed for various therapeutic purposes. The specific type of embolizing agent chosen depends on the target vessel, the desired outcome, and the patient's condition.

Commonly used embolizing agents include particulate materials like polyvinyl alcohol (PVA) spheres, microspheres made of gelatin or other biocompatible polymers, and calcium hydroxyapatite. These particles are delivered through a catheter to the site of the intended blockage. Another category includes liquid agents such as cyanoacrylate adhesives or n-butyl cyanoacrylate (NBCA), which polymerize and solidify within the vessel, creating a permanent occlusion.

Embolization procedures are utilized to treat conditions such as arteriovenous malformations (AVMs), which are abnormal connections between arteries and veins. They are also used to control bleeding from traumatic injuries or internal hemorrhages, for example, in cases of gastrointestinal bleeding or nosebleeds. In oncology, embolization can be used to deliver chemotherapy directly to a tumor or to starve a tumor of its blood supply, a technique known as transarterial chemoembolization (TACE) or transarterial radioembolization (TARE). Additionally, embolization plays a role in managing uterine fibroids and varicoceles. The goal is always to occlude specific vessels to achieve a therapeutic effect while minimizing damage to surrounding healthy tissues.
