Digital Subtraction Angiography (DSA) is a radiological procedure used to detect blood vessel abnormalities in detail. While it is highly beneficial, it’s important for patients to understand the potential side effects of DSA before undergoing the procedure.
Like any medical procedure, DSA carries some risks and potential complications. Being aware of these possible side effects beforehand allows you to prepare better and undergo the procedure more safely.
Although DSA is considered a minimally invasive procedure, there are several side effects that may occur afterward. These effects can range from mild to serious depending on the patient’s health condition and how their body responds to the procedure.
One of the most common side effects of DSA is an allergic reaction to the contrast agent used. The contrast dye helps make blood vessels more visible during the procedure but can cause allergic reactions in some patients.
Symptoms may include itching, skin redness, rashes, or in severe cases, shortness of breath or anaphylaxis.
If you have a history of allergies to iodine, foods, or certain medications, it is crucial to inform your doctor beforehand. With this information, the medical team can take preventive measures to reduce the risk of an allergic reaction.
A common local side effect after DSA is bruising, pain, or swelling at the catheter insertion site—usually in the groin or arm. This is generally harmless and will resolve on its own within a few days.
However, in some cases, minor bleeding, blood clot formation (thrombosis), or pseudoaneurysm (a blood-filled bulge outside the artery) may occur.
Other rare but serious complications include infection, blood vessel damage, or embolism (blockage caused by air or blood clots).
Kidney Function Impairment
A less common but important side effect is kidney function impairment due to the nephrotoxicity of contrast dye, especially in patients with pre-existing kidney disease.
Additionally, complications such as arterial dissection (tearing of the blood vessel) or embolism affecting vital organs can occur, though they are very rare.
Proper preparation before undergoing DSA is essential to minimize side effects and ensure accurate, safe results.
Before the procedure, patients must consult with a specialist. The doctor will explain in detail the benefits, steps, and risks of the DSA procedure.
A full medical check-up is highly recommended to ensure the body is fit for the procedure. This includes:
Medical history and physical examination
Laboratory tests (kidney function, liver function, blood tests, urine analysis)
Other supporting exams as needed
For patients with a history of diabetes, hypertension, or other chronic illnesses, sharing your medical background and current medications is an essential part of the preparation.
Patients are usually required to fast for 4–6 hours before the procedure. Regular medications can generally be taken unless advised otherwise by your doctor.
For patients taking blood thinners (anticoagulants), the doctor will assess the risk of bleeding and thrombosis before proceeding.
While DSA can involve some side effects, most of them can be prevented or managed with proper preparation and care from a competent medical team.
At National Hospital, every DSA procedure is conducted under strict safety standards and supported by modern medical equipment.
