Digital subtraction angiography (DSA) is a radiographic or fluoroscopic technique which is used for the diagnosis of various vascular disorders. The technique is also utilized for the visualization of blood vessels in the soft dense tissue environment or a bone. Digital subtraction angiography is applied for obtaining clear images of the arteries and is also highly effective in contrasting arterial structures with the surrounding bone and tissue material. Digital subtraction angiography has proven to be efficient in the identification of abnormalities such as ulcerated plaques, stenosis, occlusions and aneurysms. In addition to its application in carotid arteries this technique is also widely used in the evaluation of vascular by-pass grafts, aortic arch anomalies and aortic coarctation. The technique is being replaced by computed tomography angiography (CTA) as CTA is a less invasive test which produces 3D images.

The digital subtraction angiography market is expected to show a healthy growth in the near future primarily due to technological advancements and launch of new products in this market space. Moreover, rising interest of people for precise and accurate diagnosis is another factor expected to increase the market for digital subtraction angiography. A growing aging population is regarded as one of the most prominent factors responsible for increasing the risk associated with vascular disorders such as. It has been estimated that currently, the number of people aged over 60 years have doubled as compared to the early 1980s. This number is further expected to quadruple by 2050. Hence, accelerated growth in elderly population is poised to be a major driver for this market. Furthermore, rising incidences of cardiovascular diseases (atrial fibrillation) has led to corresponding increase in the number of patients suffering from stroke. For instance, according to the Asia-Pacific Stroke Conference (APSC) held in Japan in 2012, nearly 8 million people were diagnosed with atrial fibrillation (abnormal heart rhythm) in China. This high number of patients suffering from cardiovascular disorders would increase the demand for DSA.
The report of global digital subtraction angiography can be classified based on the types of procedures and end users. The type of procedures category can be subdivided into intravenous digital subtraction angiography and intra-arterial digital subtraction angiography. The end users segment could be further classified into diagnostic centers, hospitals and academic research laboratories. The report on digital subtraction angiography could be also subdivided into regions namely North America, Europe, Asia-Pacific and Rest of the World. Of these geographies, currently North America account for the largest share of the market followed by the European region. In the future these two regions are expected to witness slow growth rate due to market saturation and would only be driven due to replacement of old systems by the new systems. On the contrary, Asia-Pacific region is expected to witness highest growth rate during the forecast period. This could be witnessed due to increasing number of patients with cardiovascular disorders and aging population. Asia countries such as Brazil, China and India are expected to witness impressive growth due to increasing disposable income and presence of large population base. Moreover, increasing investment of the on the healthcare infrastructure and many manufacturers entering in these market.
Some of the major players operating in this global digital subtraction angiography market include GE Healthcare, Siemens AG, Philips Healthcare, Toshiba Corporation, Medtronic, Inc., Boston Scientific Corporation, Abbott Vascular, St. Jude Medical, Shimadzu Corporation, Cordis Corporation and other prominent players.
