A local anesthetic is administered to numb the area.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most patients remain awake during the procedure, although mild sedation may be provided for comfort.<\/span><\/p>\n<h3><b>Step 2: Catheter Insertion<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A small puncture is made in an artery, commonly through:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Radial artery (wrist)<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Femoral artery (groin)<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">A thin flexible catheter is inserted into the artery and carefully guided to the blood vessels being examined.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Using real-time X-ray guidance, the Interventional Neuroradiologist navigates the catheter safely to the target area.<\/span><\/p>\n<h3><b>Step 3: Contrast Dye Injection<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Once the catheter reaches the desired location, a contrast dye is injected.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The dye makes blood vessels visible on X-ray images and helps create detailed vascular maps.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During this stage, some patients may briefly experience:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Warm sensation<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mild flushing<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Metallic taste in the mouth<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">These sensations are completely normal and disappear within seconds.<\/span><\/p>\n<h3><b>Step 4: Image Acquisition<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">As the contrast dye flows through the blood vessels, a series of high-resolution X-ray images is captured.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The digital subtraction technology removes surrounding tissues and bones from the images, producing exceptionally clear views of the vascular anatomy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Doctors evaluate these images to identify:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight:

imaging is completed, the catheter is removed carefully.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Pressure is applied to the puncture site or a vascular closure device may be used to prevent bleeding.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most DSA procedures take approximately 30 to 60 minutes, depending on the complexity of the condition.<\/span><\/p>\n<h4><b>What Happens After DSA?<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Following the procedure, patients are monitored in a recovery area for a few hours.<\/span><\/p>\n<p><span style=\"font-weight:

patients can return home on the same day.<\/span><\/p>\n<h4><b>Is DSA Painful?<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">DSA is generally well tolerated and not painful.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Patients may feel:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A slight prick during local

uncommon.<\/span><\/p>\n<h5><b>What Are the Risks of DSA?<\/b><\/h5>\n<p><span style=\"font-weight: 400;\">DSA is considered a very safe procedure when performed by experienced specialists.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Potential risks include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Minor
