Cerebral Angiography

Application Details :

A medical procedure called cerebral angiography is used to see and assess the blood arteries in the brain. Neurologists, neurosurgeons, and interventional radiologists use it as a critical diagnostic tool to evaluate a variety of disorders relating to the blood flow to the brain. A contrast dye is injected during the process into the arteries supplying blood to the brain, making it possible to clearly see these vessels on X-ray images. The presence of aneurysms, arteriovenous malformations (AVMs), stenosis (narrowing), or blockages in the brain's blood vessels can be determined with the help of cerebral angiography. A catheter is typically introduced during the surgery through a tiny incision in the arm or groin, then it is carefully steered through the arteries until it reaches the blood channels in the brain. Once in place, the contrast dye is injected, and a number of real-time X-ray images are taken. These images offer thorough details about the size, shape, and location of any vascular anomalies or blockages, assisting medical professionals in making defensible decisions about available treatments. For the diagnosis of numerous cerebrovascular illnesses, such as ischemic strokes, hemorrhages, and vascular abnormalities, cerebral angiography is regarded as the gold standard. Cerebral angiography is an invasive treatment that has dangers, such as allergic responses to the contrast dye, bleeding at the catheter insertion site, or difficulties with the placement of the catheter, despite the fact that it can be helpful in diagnosing certain conditions. The knowledge gained from this operation is extremely helpful in making treatment decisions, such as endovascular procedures to open blocked arteries or repair aneurysms, or surgical interventions for AVMs. Cerebral angiography has become safer and more precise thanks to developments in medical imaging technology, such as digital subtraction angiography, which also reduces radiation exposure and enhances image quality. In conclusion, cerebral angiography is an essential technique in the fields of neurology and neurosurgery that allows medical practitioners to identify and treat a variety of cerebrovascular diseases, ultimately leading to better patient outcomes and quality of life.
