When is angiography of the femoral artery access site indicated?

Angiography of the femoral artery access site is indicated prior to the deployment of a closure device to ensure that there are no residual vascular issues at the access site. This step is crucial, as it allows for the detection and assessment of any potential complications such as arteriovenous fistulas, hematomas, or significant vascular injury before sealing the access point. Performing angiography at this stage helps to confirm hemostasis and assess the patency of the femoral artery, which is vital for patient safety and optimal outcomes.

Addressing angiography only after the procedure is completed may lead to missed opportunities to address any complications before sealing the site. Similarly, relying solely on a history of complications or the appearance of bleeding symptoms does not proactively ensure safety. Proactive imaging ensures that any potential issues can be handled before they escalate.
