An arteriovenous malformation (AVM) of the brain is an abnormality of the blood vessels that connect arteries and veins, which obstructs blood flow and oxygen circulation.

Arteriovenous malformations can occur anywhere in the body, resulting in malnutrition and dystrophy of some functional areas. Therefore, the method of embolization of limb vascular malformations through digital subtraction angiography (DSA) is a technique that is widely applied today to solve this problem.

Digital subtraction angiography (DSA) captures images of blood vessels using X-rays. This technique can be applied to many different blood vessels in the body and combined with local thrombolytic injection treatment. How does the digital subtraction angiography and local thrombolytic injection treatment for vascular thrombosis take place?
