Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to an aneurysm or blood vessel through the implantation of detachable platinum wires, with the clinician inserting one or more into the blood vessel or aneurysm until it is determined that blood flow is no longer occurring within the space.
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
Endovascular coiling, surgical clipping, cerebral bypass surgery, pipeline embolization An intracranial aneurysm , also known as a cerebral aneurysm , is a cerebrovascular disorder characterized by a localized dilation or ballooning of a blood vessel in the brain due to a weakness in the vessel wall.
Endovascular embolization is a technique used by neurointerventionalists in which particles, glue, or coils are lodged inside the AVM to prevent blood flow through the abnormal channel. During this treatment, an interventional radiologist guides a catheter through a blood vessel accessed from the patient's leg to the site of the AVM.
Hemorrhoidal artery embolization (HAE, or hemorrhoid artery embolization) is a non-surgical treatment of internal hemorrhoids. [ 1 ] The procedure involves blocking the abnormal blood flow to the rectal (hemorrhoidal) arteries using microcoils and/or microparticles to decrease the size of the hemorrhoids and improve hemorrhoid related symptoms ...
Flow diverters are treatment for intracranial aneurysms alternative to endosaccular coil embolization, although the techniques can be combined, especially in large/giant aneurysms. It is mainly effective in wide neck unerupted saccular aneurysms , that are difficult to coil because of the tendency of the coils to fill the parent artery ...
In recent decades, cerebral angiography has so assumed a therapeutic connotation thanks to the elaboration of endovascular therapeutic techniques. Embolization (a minimally invasive surgical technique) over time has played an increasingly significant role in the multimodal treatment of cerebral MAVs, facilitating subsequent microsurgical or ...
In cases where conservative treatment is not sufficient, endovascular procedures may be considered. These include stenting/stent-grafting of the true lumen, (coil) embolization of the false lumen/aneurysm, catheter-directed local thrombolysis, percutaneous transluminal angioplasty, and catheter-directed local papaverine infusion at 30 mg/h.
