Ultrasound-guided aspiration is generally considered safe and effective when performed by a trained healthcare professional. However, there is a risk of complications, such as bleeding, infection, or damage to nearby organs or tissues. Patients should inform their healthcare provider about any allergies or medical conditions they have, and whether they are pregnant. They may also need to stop taking certain medications before the procedure. After the procedure, patients may experience some discomfort or swelling at the puncture site, and they should follow any instructions provided by their healthcare provider.
