Werndale Hospital provides specialized Endovascular surgery for AVM with an emphasis on precise vascular targeting, controlled embolization, and individualized treatment planning for AVMs. Established in 1991, the accredited hospital is based in Carmarthen, United Kingdom and has 19 beds supported by modern neurovascular and interventional facilities.

Endovascular Surgery for AVM is a catheter-based approach used to reduce blood flow through an arteriovenous malformation. A microcatheter is guided into the abnormal vascular network, and an embolic substance is delivered to selected feeding vessels under continuous imaging guidance. Complete closure of an AVM is not always achieved through embolization alone, so the procedure may be used before microsurgical resection or stereotactic radiosurgery. Cerebral angiography and other imaging studies help specialists evaluate the AVM and determine the safest treatment strategy.
