Post-Procedure Care After Cerebral Angiography

Cerebral angiography is a diagnostic procedure that involves inserting a catheter into an artery and injecting a contrast dye to visualize blood vessels in the brain. After the procedure, proper care and monitoring are essential to ensure a smooth recovery and prevent complications.

Monitor the Puncture Site

Check for signs of bleeding, bruising, swelling, or pain at the incision site. Since the procedure involves arterial puncture, effective hemostasis (bleeding control) is crucial. Doctors typically apply firm pressure for an extended period after the catheter is removed. Once pressure is released, it's important to continue observing the site for any delayed bleeding or hematoma formation.

Stay Hydrated to Aid Contrast Elimination

Drink plenty of water after the procedure to help flush out the contrast agent. The contrast dye used during angiography is primarily excreted through the kidneys. Adequate hydration supports kidney function and speeds up the elimination process, reducing the risk of contrast-induced nephropathy, especially in patients with pre-existing kidney conditions.

Watch for Changes in Vital Signs

Pay close attention to blood pressure, heart rate, and overall well-being. As a minimally invasive procedure, cerebral angiography can still place stress on the body. This is particularly important for elderly patients or those with chronic health conditions such as hypertension, diabetes, or cardiovascular disease. Regular monitoring helps detect early signs of adverse reactions or complications.

Follow Activity Restrictions

If the femoral artery was used for catheter insertion, remain lying down for at least 24 hours. During this time, avoid putting weight on the affected leg to prevent dislodging the clot at the puncture site. Additionally, medical staff will periodically check the pulse in the dorsalis pedis artery of both feet to ensure adequate blood flow to the lower limbs and prevent ischemic complications.
