Arteriovenous Malformations (AVMs) stand out as the largest single application segment driving the consumption of liquid embolic agents, currently accounting for a substantial portion of the domain's total revenue. AVMs are abnormal tangles of blood vessels that bypass the normal capillary system, and when they occur in the brain, they carry a high risk of rupture and catastrophic hemorrhage. Embolization using liquid agents is now considered a vital component of the treatment strategy for these complex neurovascular lesions.

The inherent structure of an AVM, with its numerous small feeding vessels, makes it an ideal target for liquid embolics. The agents can be injected to flow precisely into the abnormal nidus (the central core of the malformation), sealing off the blood supply and reducing the size and pressure within the lesion, often as a prelude to surgical resection or focused radiation therapy. This ability to pre-treat or cure the malformation non-surgically highlights the essential role of this technology.

Continuous product innovation, particularly the development of non-adhesive polymer-based systems like EVOH (Ethylene Vinyl Alcohol Copolymer), is enhancing the controllability and safety of AVM procedures. This focus on improving the handling characteristics and minimizing the risk of non-target embolization is essential, securing the AVM application as the main growth engine for the Liquid Embolic category.

FAQ

Q: Why are Arteriovenous Malformations (AVMs) the largest application for liquid embolics? A: Their complex structure, consisting of a tangle of abnormal vessels (nidus), is highly suited for the precise, deep sealing action provided by liquid agents.

Q: What is a key benefit of liquid embolic agents in treating AVMs? A: They allow specialists to reduce the size and pressure within the malformation, either as a definitive cure or as preparation for surgical removal.
