Introduction to Brain Aneurysm Glossary

Understanding medical terminology can be daunting, especially when faced with a complex condition like a brain aneurysm. This glossary goes over some useful and important key terms related to brain aneurysms. Click on each term to read the relevant comprehensive blog post or article to find out more about this condition to be informed and empowered. By familiarizing yourself with these terms, you can better understand your diagnosis, treatment options, and the overall management of brain aneurysms.


Basic Definitions and Medical Terminology

  • Aneurysm: Brain aneurysm is bulging or ballooning of a blood vessel supplying the brain. In the brain, this can lead to serious complications if it ruptures.
  • Cerebral Aneurysm: Specifically refers to aneurysms that occur in the brain’s blood vessels.
  • Unruptured Aneurysm: Unruptured brain aneurysms are abnormal bulges that develop in the walls of blood vessels in the brain. These bulges can occur anywhere in the brain and often go unnoticed, as they typically do not cause any symptoms. 
  • Ruptured Aneurysm: When an aneurysm bursts, leading to bleeding in or around the brain, requiring immediate medical attention. (Read our in-depth “Unruptured and Ruptured Brain Aneurysm” article to better understand the difference between the two.) 
  • Hemorrhage: This is active bleeding within the brain or surrounding areas, often resulting from a ruptured aneurysm. However, a brain hemorrhage can also be caused by a variety of other health conditions or by direct trauma to the head. 


Diagnostic Terms

  • Cerebral Angiogram: A cerebral angiogram is a minimally invasive procedure and an important tool to confirm brain aneurysms and other blood vessel abnormalities.
  • CT Scan (Computed Tomography): An imaging technique that uses X-rays to create detailed cross-sectional images of the brain, useful for detecting bleeding or aneurysms.
  • CTA: This is a special type of CT scan that aims specifically at scanning blood vessels.
  • MRI (Magnetic Resonance Imaging): Uses magnetic fields and radio waves to produce detailed images of the brain, helpful in diagnosing aneurysms.
  • MRA (Magnetic Resonance Angiography): A type of MRI specifically designed to image blood vessels and detect aneurysms. (Read more about the diagnostic tests above in detail that Dr. Manish Taneja, our brain aneurysm specialist, in Singapore, uses to diagnose and assess this condition. 


    Brain Aneurysms Treatment Options in Singapore

    • Clipping: This is a surgery where a small metal clip is placed at the base of the aneurysm to stop blood flow and prevent rupture.
    • Minimally Invasive Procedures and Treatments: Minimally invasive treatment uses smaller incisions, often times, being less risky than open surgery. Read more about the latest advances in brain aneurysm care and best minimally invasive treatments for brain aneurysm with Dr. Manish Taneja. 
    • Coiling (Endovascular Coiling): Coiling and stent placement are minimally invasive procedures typically recommended for patients with a ruptured or unruptured brain aneurysm.The coil is inserted into the aneurysm via a catheter. They help reinforce and stabilize the weakened blood vessel walls to reduce the risk of rupture or re-rupture. 
    • Flow Diverter: Flow diversion is an innovative and minimally invasive treatment option for complex, large, or wide-necked brain aneurysms. It is a great option for aneurysms that may not be suited for traditional coiling or clipping technique. The advantages include shorter recovery times and a less invasive approach and a significant advancement in the field of neurovascular surgery. This procedure uses a specialized stent-like device, known as a flow diverter, within the affected blood vessel. It appears like a braided cylindrical mesh device, which is implanted across the aneurysm 
    • Embolization: Endovascular coil embolization is another minimally invasive and effective treatment for brain aneurysms. During this procedure, a thin catheter is guided through the arteries, usually from the groin, to the site of the aneurysm. Platinum coils are then carefully inserted into the aneurysm sac, filling it and inducing clot formation.


    Medications and Management

    • Anticoagulant: Medications that help prevent blood clots, often used in managing aneurysms.
    • Blood Pressure Management: Keeping blood pressure under control is crucial in preventing aneurysm growth and rupture.
    • Pain Management: Various approaches are used to relieve the symptoms associated with aneurysms, including medications and therapies.



    • Neurointervention specialist: A doctor with specialized training in the use of minimally invasive, image-guided techniques to treat complex conditions of the brain, neck, and spine.
    • Interventional Radiologist: A specialist in performing minimally invasive procedures, such as coiling and embolization, to treat aneurysms.


    Associated Conditions

    • Brain Arteriovenous Malformation (AVM): Brain arteriovenous malformation (AVM) is an uncommon condition that is due to abnormal connection between arteries and veins in the brain substance.
    • Hypertension: High blood pressure is a significant risk factor for developing aneurysms. Read more about other brain aneurysm risk factors in our informative article.
    • Stroke: Brain aneurysms is a significant factor to consider when it comes to stroke risk. This is because when a brain aneurysm ruptures, it can cause bleeding in the brain, leading to a hemorrhagic stroke. 


    Final Thoughts on Brain Aneurysm

    Put Brain Aneurysm on Your Health Radar

    Did you experience the worst headache of your life? Could it be a brain aneurysm that ruptures, which means bleeding in the brain? Thoughts could be racing through your mind. Then what is the difference between unruptured (a weak or thin spot on an artery in the brain that balloons) or ruptured brain aneurysm? If you’re wondering, then the Supreme Vascular and Interventional Clinic is here to help. It’s important to look out for the tell-tale brain aneurysm symptoms, signs, causes, and risk factors.

    Dr. Manish Taneja has been performing brain aneurysm treatments since 1995 from surgical clipping to latest minimally invasive procedures. Each patient is unique as is the size and location of the aneurysm. Your brain has different conditions to treat the aneurysm and artery vessel walls of a blood vessel in the brain. This calls for personalised brain aneurysm treatment depending on your symptoms, family, history, medication, and more. A simple CT scan could be just what the doctor ordered and the first step in early detection and prevention of a brain aneurysm. Come in for an easy consultation with our brain aneurysm specialist in Singapore to be on your health radar.
