Cerebral arteriovenous malformation is a disease that mainly occurs in the central nervous system of adolescents. It is a congenital abnormality of vascular development. Tissue hypoperfusion, high venous pressure, resulting in cerebral ischemia delayed dysfunction and malformed blood vessel rupture and bleeding, which can be life-threatening. The incidence rate of cerebral arteriovenous malformation is 0.01%~0.5%. The vast majority of patients with cerebral arteriovenous malformation develop before the age of 40. Manifestations and causes of death and disability.
As continuous development and application of new interventional embolic materials, LavaTM Liquid Embolic System has made micro-invasive endovascular embolization widely used in clinical practice. The choice of embolic material is crucial to the embolization effect. An ideal embolic material should have:
①The material is liquid and easy to pass through the slender microcatheter.
②Easy to control and good development.
③ It can ensure a long enough injection time to embolize arteriovenous malformations without sticking to the tube.
④ The diffusibility is better, it can diffuse from the arterial end to the capillary, and it does not Spills into veins.
⑤Embolization effect is permanent, no recanalization phenomenon.
⑥No toxicity, no biological activity, no reaction with brain tissue.
⑦ Easy surgical resection after embolization.
According to the above characteristics, LAVA is used for embolization of cerebral arteriovenous malformations.
