Thanks to the digital subtraction angiography (DSA) system, many cardiovascular, cerebrovascular, and neurological diseases (especially myocardial infarction and stroke) have helped doctors make clear diagnoses and patients receive timely intervention.

Digital subtraction angiography (DSA angiography) is a method performed for patients indicated for endovascular embolization, endovascular aneurysm surgery, arterial stent placement,... or in the diagnosis of vascular diseases.

The carotid arteries are one of two circulatory systems that supply blood to the brain. When the carotid arteries are narrowed or blocked, symptoms such as cerebral ischemia can occur. There are many different causes of narrowing or blocking, such as arterial trauma or atherosclerosis. In these cases, the patient will undergo carotid artery angioplasty and stenting for treatment.

Digital subtraction cerebral angiography is a brain imaging technique that injects iodine contrast dye through a catheter into the cerebral artery area to visualize the cerebral arterial and venous systems.
