What is a common complication associated with angiography?

• A. Infection at the injection site
• B. Hematoma formation at the puncture site
• C. Excessive bleeding during the procedure
• D. Allergic reactions to imaging agents

Answer: (B)

Hematoma formation at the puncture site is indeed a common complication associated with angiography. This occurs when there is bleeding into the soft tissue surrounding the site where the catheter is inserted. During angiography, a needle is introduced into a blood vessel to allow for the access of catheters, and sometimes this procedure can lead to damage to the vessel wall or an inadequate seal once the needle is withdrawn. Consequently, blood can leak out of the vessel and accumulate in the surrounding tissue, creating a hematoma.

The presence of a hematoma can lead to pain, swelling, and discoloration at the site, and while most hematomas resolve on their own, some may require further intervention if they become large or symptomatic. Recognizing the risks of hematoma formation is important for clinicians in order to minimize complications and manage them effectively if they arise.

Other potential complications, such as infection at the injection site, excessive bleeding, and allergic reactions to imaging agents, are also possible but occur less frequently in comparison to hematoma formation.
