Stroke is a medical condition caused by impaired blood flow to the brain, either due to a blockage or hemorrhage. In modern stroke treatment, speed and accuracy of diagnosis are crucial for the outcome of treatment. One crucial procedure is stroke DSA .
DSA in stroke helps doctors see the condition of the brain's blood vessels in detail, so that the source of the problem can be identified more accurately and further therapeutic measures can be carried out according to DSA findings.
What is DSA?
DSA stands for Digital Subtraction Angiography , a procedure that uses contrast media and X-ray technology to image blood vessels. In the context of DSA in stroke cases , the procedure focuses on thoroughly evaluating the brain's blood vessels.
Through DSA, doctors can see:
- Location of blood vessel blockage
- Narrowing of the arteries
- Aneurysm (widening of blood vessels)
- Other blood vessel disorders
The images produced by DSA are very detailed, so they help in medical decision-making, and can even assess the risk of recurrent stroke in the future of stroke patients.
Why is DSA in Stroke Important?
In stroke cases, time is crucial. DSA for stroke provides more precise information than some other imaging tests, especially when intervention is needed.
DSA for stroke is usually performed in conditions such as:
- Ischemic stroke due to large/small blockage
- Hemorrhagic stroke due to aneurysm
- Suspicion of vascular malformation
- Evaluation before neurosurgical intervention
With DSA in stroke, doctors can determine whether the patient requires further action such as thrombectomy or embolization.
Actions that can be taken together with DSA in stroke
The advantages of DSA for stroke are not only as a diagnostic tool but also as a means of intervention. Some procedures that can be performed after DSA for stroke include:
1. Mechanical Thrombectomy
In ischemic strokes caused by blockage of large blood vessels, DSA stroke allows doctors to remove blood clots using a special catheter in cases of new strokes.
2. Coiling in Aneurysm
If an aneurysm is found that is at risk of rupture or has already ruptured, DSA can be followed up with coiling to close the part of the blood vessel that has the aneurysm abnormality.
3. Embolization
DSA is also used to close abnormal blood vessels that cause bleeding or structural abnormalities.
Thus, DSA acts as both a diagnostic procedure and a follow-up therapeutic planning procedure.
How is the DSA Stroke Procedure Performed?
The DSA stroke procedure involves inserting a small catheter through a blood vessel in the groin. The catheter is guided toward the brain's blood vessels, and then a contrast agent is injected to enhance the image of the blood vessels.
Patients usually receive local anesthesia or light sedation during a stroke DSA. This procedure is performed by a doctor specializing in interventional neurology.
DSA Safety in Stroke
In general, DSA is considered a safe procedure when performed as indicated and by an experienced medical team. As with any medical procedure, there are risks, but a thorough pre-procedure evaluation helps minimize potential complications.
The decision to perform DSA always takes into account the benefits and risks in a comprehensive manner.
Immediately undergo an examination and consultation at EMC Hospital
DSA is a crucial technology in modern stroke care. With its detailed visualization capabilities, if you or a family member experiences symptoms such as sudden weakness on one side of the body, speech problems, severe dizziness, or decreased consciousness, do not delay seeking medical attention. Early evaluation provides a better chance of optimal treatment.
For further examination and consultation regarding stroke and stroke diagnostic procedures, you can consult a neurologist at EMC Alam Sutera Hospital . Supported by an experienced medical team, treatment is comprehensive and tailored to each patient's medical needs.
