cyst aspiration & wire localization

 CYST ASPIRATION

 
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
 
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.
