Vascular Interventions: Real-time imaging using Digital Subtraction Angiography at Yashoda Hospitals

A computerized X-ray machine called the DSA (Digital Subtraction Angiography) test provides a clear and exclusive view of the blood vessels, which aids in understanding the problems associated with blood flow. This minimally invasive technique involves making a small incision to insert the catheter through the blood vessels to reach the target sites, such as the brain, heart, or legs.

Yashoda Institute of Radiology and Imaging combines state-of-the-art radio-imaging equipment with knowledgeable radiologists and technicians to provide patients and referring physicians with a comprehensive evaluation of suspected illnesses or abnormalities.

Interventional Radiology (IR) is an amalgamation of the detection and simultaneous correction of abnormalities inside the human body. The scope of imaging sciences is expanding much beyond diagnostics and adding value to various image-guided treatments. Interventional radiologists make use of imaging modalities such as X-ray, CT, MRI, and DSA for guidance and to achieve better outcomes.

Who needs Digital Subtraction Angiography?

• An individual with stroke symptoms or any brain-related conditions to rule out blood clots or aneurysms.
• When a person has trouble walking or has suspected poor blood flow in their legs, DSA can help rule out peripheral-related conditions like peripheral artery diseases.
• When a patient is prepared for blood vessel surgeries, such as angioplasties or stents, DSA assists in assessing the blood vessels both before and after the procedure.
• Individuals who experience chest pain & are at high risk of heart attacks can undergo DSA for early detection of blood clots in the heart’s blood vessels.
• An individual with suspected abdominal & kidney aneurysms. 
• For people with lung diseases like pulmonary embolism, DSA is necessary to check for clots in their blood vessels.

How is Digital Subtraction Angiography done?

Before the procedure, local anesthesia is given at the site where a catheter is placed through the groin or wrist. The insertion makes it easier to reach the target regions, which could be the heart, brain, or legs. A contrast dye is injected through these blood vessels once the catheter is in the target area. This improves the visualization of the X-rays, and the computer ensures that the non-blood vessel images are subtracted during image recording, leaving only the blood vessel-related findings visible on the X-ray. 

Benefits of Digital Subtraction Angiography:

• Minimally invasive & less radiation exposure.
• Navigation method for healthcare professionals during surgical procedures such as stent placement, etc.
• Accurate diagnosis of many conditions associated with blood vessel damage or blockages in different regions of the body.
