An embolization device is a [[medical device]] used in interventional radiology and vascular surgery to block or restrict blood flow to a specific area of the body. It is often employed to treat various medical conditions, including:

Hemorrhage Control: Embolization devices can be used to stop bleeding, particularly in cases of traumatic injuries or post-surgical bleeding. They are inserted into the blood vessels leading to the bleeding site and block the flow of blood.

Tumor Embolization: In cases of cancer, especially in the liver or kidney, embolization devices can be used to cut off the blood supply to tumors. This is known as transcatheter arterial embolization (TAE) or transarterial chemoembolization (TACE), and it helps shrink or slow the growth of tumors.

Uterine Fibroid Embolization (UFE): For women with symptomatic uterine fibroids, an embolization procedure can be performed to block the blood flow to these non-cancerous growths, leading to their shrinkage and symptom relief.

Aneurysm Treatment: Embolization devices are used to treat certain types of aneurysms, which are weak areas in blood vessel walls that can bulge and potentially rupture. By filling the aneurysm with embolic material, the risk of rupture is reduced.

Varicocele Embolization: Varicoceles are enlarged veins in the scrotum, often causing discomfort or fertility issues. Embolization devices can be used to block these veins, improving symptoms and potentially enhancing fertility.

Arteriovenous Malformation (AVM) Treatment: AVMs are abnormal tangles of blood vessels that can cause various health issues. Embolization devices can help close off the abnormal vessels, reducing the risk of bleeding or other complications.

Embolization devices come in various forms, including coils, particles, gels, or liquid embolic agents. The choice of device depends on the specific medical condition being treated and the location within the body.

The procedure involves the insertion of a catheter into the blood vessels, typically through a small incision in the groin, and then guiding the embolization device to the target area using imaging techniques such as fluoroscopy. Once in place, the device is deployed to block or restrict blood flow, effectively treating the underlying condition.

Embolization procedures are less invasive than traditional surgical methods and often result in shorter recovery times and fewer complications. They are typically performed by interventional radiologists or vascular surgeons with specialized training in these techniques.

Despite advances in [[embolization]] devices, the [[coiling]] of [[small intracranial aneurysm]]s is still scrutinized. High [[occlusion]] rates are achievable, especially in [[unruptured aneurysm]]s, with [[coil]] type and [[packing]] density suggesting an association with complete occlusion. Technical complications may be influenced by [[aneurysm geometry]]. Advances in endovascular technologies have revolutionized small aneurysm treatment, with this series demonstrating excellent aneurysm occlusion, especially in unruptured aneurysms
