cyst aspiration & wire localization


A cyst is a fluid filled structure, usually diagnosed with ultrasound. Aspirations are done infrequently, however an aspiration can be performed to drain fluid from a cyst. Draining the fluid can reduce the size of the lump and relieve the pain and pressure caused by cysts. During an aspiration, a radiologist will use ultrasound to locate the cyst. The skin will then be cleaned and a local anesthetic will be injected to numb the skin. A needle will then be used to extract the fluid. This will be documented with ultrasound imaging. A bandage will be applied to the puncture site. The fluid is usually discarded, though occasionally may be sent to pathology.
Wire localization is done before breast surgery to localize a particular area in the breast which cannot be felt prior to surgery. This localization can be done under mammographic, ultrasonographic or MRI guidance. The procedure is performed by a radiologist with a technologists assisting. A local anesthetic will be injected in the skin as well as deeper to numb the area of concern. A needle will be placed into the breast and this placement will be verified with imaging. A wire is then passed through the needle to mark the site for the surgeon. The wire has a hook on the end to keep it in place. The needle is the removed, leaving the wire behind. The site is dressed temporarily for transport to the surgery department.
