Stroke is a serious health condition that can occur when blood flow to the brain is disrupted. Depending on the type of stroke, there are different treatment options available, one of which is interventional embolization using liquid embolic agents.
Interventional embolization is a minimally invasive procedure that involves the insertion of a catheter through an artery to the site of the blockage in the brain. The liquid embolic agent is then injected to block the blood flow to the affected area, preventing further damage from occurring.
Liquid embolic agents are biocompatible substances that are designed to flow easily into the smallest of vessels in the brain, creating a solid mass that blocks the vessel. This process is called embolization and is used in the treatment of various conditions such as aneurysms and arteriovenous malformations (AVMs).
There are different types of liquid embolic agents available for interventional embolization, including Onyx, N-butyl cyanoacrylate (nBCA), and Ethylene-vinyl alcohol copolymer (EVOH). Onyx is a sclerosing agent that is commonly used in the treatment of intracranial AVMs, while nBCA is typically used in the treatment of cerebral aneurysms. EVOH is a biocompatible material that is used to treat arteriovenous malformations, AVMs, and cerebral aneurysms.
Interventional embolization using liquid embolic agents is a safe and effective treatment option for stroke patients. The procedure can be performed quickly, and patients typically experience minimal pain and discomfort. In most cases, patients are able to return to their normal activities within a few days following the procedure.
Overall, interventional embolization using liquid embolic agents is a positive development in the treatment of stroke. It offers a minimally invasive, safe and effective option for patients, allowing them to regain their quality of life as quickly as possible.
