Digital Subtraction Angiography (DSA)
What is Digital Subtraction Angiography (DSA)?
Digital subtraction angiography (DSA) is a fluoroscopic technique used extensively in Interventional Radiology for visualizing blood vessels. Radiopaque structures such as bones are eliminated ("subtracted") digitally from the image, thus allowing for an accurate depiction of the blood vessels.
Our DSA at Gleneagles is equipped with the latest 3D technology to allow better depiction of blood vessels and improved treatment results.
Why is Digital Subtraction Angiography (DSA) required?
There are numerous indications for angiography and their number has been on the rise ever since Interventional Radiology has been shown to successfully supplant many open vascular procedures. Examples include:
- Trans-arterial chemoembolisation of liver cancer
- Uterine fibroid embolisation
- Prostate artery embolisation
- Aneurysm and vascular malformation endovascular treatment
- Arterial balloon angioplasty and stenting
- Endovascular thrombectomy
