kierreembolisaattorit

Kierreembolisaattorit, also known as coil embolization devices, are medical implants used in minimally invasive procedures to treat various vascular conditions, primarily aneurysms and arteriovenous malformations (AVMs). These devices consist of small, flexible metallic coils, typically made of platinum or other biocompatible alloys. Their primary function is to induce thrombosis, or blood clotting, within a diseased blood vessel, thereby occluding it and preventing blood flow.

The procedure for deploying kierreembolisaattorit is known as endovascular embolization. It is performed by interventional radiologists or neurosurgeons. A thin, flexible catheter is inserted into a major artery, usually in the groin, and guided under fluoroscopic (X-ray) imaging to the site of the vascular abnormality. Once in position, the coils are carefully deployed from the catheter into the aneurysm or AVM. The coils pack the space within the lesion, creating a scaffold that promotes the formation of blood clots. As thrombosis progresses, the vessel is effectively sealed off, reducing the risk of rupture or bleeding.

Kierreembolisaattorit are a valuable tool in the management of cerebrovascular diseases, such as brain aneurysms, and can also be used for peripheral vascular lesions. They offer an alternative to traditional open surgical repair, often resulting in shorter recovery times and fewer complications. The precise design and size of the coils are tailored to the specific anatomy of the lesion being treated. Careful planning and execution are crucial to ensure effective occlusion and minimize the risk of coil migration or incomplete treatment.
