Unrevealing the Indication of Cerebral DSA for Precision Diagnosis

Indication of Cerebral DSA

Delving into the realm of medical imaging, the utilization of cerebral DSA (Digital Subtraction Angiography) serves as a pivotal tool in our quest for diagnostic precision. It offers a window into the intricate pathways of the brain, providing a clear indication of vascular abnormalities, enabling healthcare professionals to make informed decisions and offer targeted treatments, ultimately enhancing patient care and outcomes.

Cerebral angiography or arteriography also known as intra-arterial digital subtraction angiography or DSA. This procedure uses a contrast material and x-ray to see how blood flows through the brain.
Specifically, a catheter is introduced into the femoral or brachial artery and passed into one of the major cervical vessels. A radiopaque contrast material is then injected through the catheter, allowing the vessel (or its origin) to be visualized.

The following are the primary indications for cerebral angiography:
1. The identification of cerebral aneurysms, arteriovenous malformations (AVMs), or fistulas. Although CT scans and MRIs can visualize these lesions, they cannot clearly characterize their exact anatomy or the arteries that feed, drain, or are otherwise involved in them. Furthermore, arteriography is essential for interventional procedures such as embolization, occlusive polymer injection, or the implantation of detachable balloons or coils to treat specific vascular abnormalities.
2. Detection and definition of the underlying lesion in subarachnoid hemorrhage patients who are regarded good surgical candidates.
3. Detection and treatment of vasospasm following a subarachnoid hemorrhage.
4. Emergency embolectomy for ischemic stroke caused by large-vessel blockage. Also, if surgical treatment such as carotid endarterectomy is being considered, angiography can characterize arterial lesions in individuals with transient cerebral ischemia episodes or strokes.
5. Examination of tiny vessels when vasculitis is suspected.
6. Diagnosis of cerebral venous sinus thrombosis.
7. Evaluation of space-occupying intracranial lesions, especially when CT scanning or MRI are not accessible.
Normal vasculature may be displaced, and in some cancers, neovasculature may cause a blush or stain on the angiography. The external carotid circulation supplies meningiomas. Certain cancers' blood supply is reduced before surgery, lowering the chance of significant bleeding during resection.
