Sequelae after angiography mainly include bleeding at the puncture site, allergy to contrast agent, and renal function impairment.
1. Bleeding at the puncture site: Angiography is an invasive examination in which contrast agent is injected into the blood vessels after inserting a guide wire through an arterial puncture to observe the blood vessels. In this process, due to the need to enter from the artery, blood seepage, bleeding, hematoma, etc. may occur after the operation at the puncture site.
2. Allergy: the test requires the use of contrast medium, commonly used contrast medium is iodine contrast medium, some people are allergic to this, may appear rash, severe anaphylactic shock, timely anti-allergy treatment.
3. Renal function damage: a few people may have renal function damage after the examination due to the contrast agent, such as acute tubular kidney injury.
