Nudelman obtained the first DSA images in 1977, and the use of this technique is now common in angiography. Digital subtraction angiography (DSA) is a component of digital radiography (DR). The diagnosis of the following diseases can be clarified by cerebral angiography: 1) aneurysms (saccular Figure a horizontal arrow, pike, and intercalated aneurysm Figure b); 2) cerebral arteriovenous malformations Figure a vertical arrow; 3) internal carotid artery cavernous sinus fistula Figure c; 4) dural arteriovenous fistula Figure d; 5) cerebral venous malformations; 6) cerebral venous sinus thrombosis Figure e, etc. In 1978 Debrun et al. had already treated cerebrovascular disease with balloon catheters, but endovascular interventional surgery was widely performed for more than 10 years, especially Guglielmi (1991) developed the detachable metal microspring coil (GDC). It is now mainly used for cerebral or spinal arteriovenous fistulas, cerebral arteriovenous malformations, internal carotid artery cavernous sinus fistulas, and dural arteriovenous fistulas. With the increasing resolution of CTA and MRA, cerebral angiography, after all, brings trauma to patients and may no longer be the ultimate means of definitive diagnosis of cerebrovascular disease in the future. However, as interventional equipment and materials are updated and physicians’ diagnosis and treatment skills are improved, interventional treatment will replace traditional surgery in cerebrovascular diseases and protect the health of the people.
