Cerebral angiography is an invasive procedure that may involve risks such as bleeding and infection at the puncture point, allergy to contrast or anesthetics, rupture of blood vessels, and cerebral infarction.
1. Bleeding or infection at the puncture point: Cerebral angiography requires inserting a catheter through the femoral artery for injection of contrast medium, which may cause uncontrollable bleeding if not handled properly. In addition, improper handling may cause uncontrollable bleeding. In addition, if care is not taken after the examination, the puncture site may become infected.
2. Allergy to contrast or anesthetics: Cerebral angiography requires injection of contrast and local anesthesia before puncture, so there is a risk of allergy to contrast or anesthetics.
3. Rupture of blood vessels: Since cerebral angiography is performed in the lumen of blood vessels, improper operation may damage the wall of blood vessels or even lead to rupture of blood vessels, especially in patients with combined atherosclerosis.
4. Cerebral infarction: patients with atherosclerotic plaques on the vascular wall may suffer a cerebral infarction due to plaque dislodgement during catheterization.
Cerebral angiography is an important diagnostic test for cerebrovascular diseases, but it also has many risks, so it is recommended that patients fully communicate with their treating doctors and decide whether to undergo the test after a detailed assessment of the patient’s condition.
