What is Digital Subtraction Angiography?
Digital subtraction angiography is a medical procedure in radiology performed to examine the body’s blood vessels after introducing a contrast dye. Subtraction includes eliminating the bone and cartilage structure from the blood vessels’ view, known as Digital Subtraction Angiography. This procedure helps a doctor to get an accurate depiction of the blood vessels. A fluoroscopic digital image combined with injection dye and real-time subtraction is considered a Digital Subtraction Angiography image.
The procedure helps guide endovascular procedures by allowing placement of devices such as balloons and stents within lesions previously identified by angiography.

Which Digital subtraction angiography techniques are used in India?
The medical procedure produces an image of the blood vessels without interfering with shadows from overlapping tissues. DSA helps a doctor provide a clear view of the vessels and only requires a lower dose of contrast medium 4. The procedure involves the following steps -
• The doctor asks a patient to lie down on the angiography table, and local anesthesia is administered at the intended puncture site to make the patient comfortable. A doctor uses the Selinger technique to gain access to a blood vessel.
• Ultrasound is performed for visualizing the vessel in real-time for puncturing.
• A standard access kit includes an instrument on which the diagnostic and therapeutic catheters are threaded.
• Sometimes a doctor may also use a micro-introducer access kit instead of a standard access kit. A micro-introducer access kit enables less traumatic entry and can be retrieved without massive bleeding should there be a re-puncturing need.
• Once the procedure is executed, a doctor applies hemostasis to the puncture site.
What complication and side effects may occur after Digital Subtraction Angiography?
Sometimes, Digital subtraction angiography may cause some side effects. Although these side effects may vary from person to person. These complications may include -
- Thrombus formation
- Local tissue damage
- Pseudoaneurysm
- Arteriovenous fistula
- Thromboembolism
- Air embolism
- Vessel dissection
- Contrast mediated nephrotoxicity
