What is a potential complication at the puncture site during neuro angiography?

A hematoma is indeed a potential complication at the puncture site during neuroangiography. This procedure involves accessing major blood vessels in the neck or groin to visualize the cerebral circulation. During the access, especially when using needles or catheters, there is an inherent risk of causing bleeding in the surrounding tissues. If blood leaks out of the vessel and collects in the surrounding soft tissues, it can form a hematoma.

This can lead to swelling, pain, and in some instances, further complications such as infection or compression of nearby structures. The fact that the procedure often involves puncturing a vessel increases the likelihood of a hematoma occurring at or near the site of access, making it a recognized complication in this context.

Other potential complications like stroke, aneurysm, and cardiac dysrhythmia, while relevant in the broader scope of neuroangiography, are less directly related to the puncture site itself. Stroke may occur due to embolism or other procedural risks, aneurysm refers to a dilation of blood vessels and can emerge as a long-term condition, and cardiac dysrhythmias are typically associated with sedation or catheter manipulation rather than the puncture site. Thus, hematoama stands out as the most pertinent complication for the punct
