Not likely. This type of biopsy, using a small needle, is usually done as a minor office procedure, possibly with ultrasound guidance. You likely can eat before the procedure, but should probably have someone available to bring you home after the biopsy. But check first with your medical provider.
Not surgery. The line btw surgeries/operations and tests/procedures is blurry, but in general, I advise patients to report procedures that result in a permanent change on their surgical history, and conditions requiring a biopsy or other test under medical history. So fnab (benign) might be a comment under thyroid nodule or breast mass in a medical history, but thyroidectomy would go under surgical history.
Surgical procedure. Fna- invasive procedure.
No. A fine needle aspiration (fna) refers to a skinny needle (18g or less) to remove cellular material for cytology evaluation. This is generally done in the office and should take 5min or less. No prep is necessary and no restrictions after. A core bx is also an office procedure using a 14g or larger needle to remove tissue samples for histology. Core bx but not fna is usually counted in risk calc.
It is a type of Biop. It is a test done to examine the cells contained in a lump or mass. This is one way to check a lump for Cancer. It is the least invasive test because it uses a very thin/fine needle to pull out a few cells and check if they are normal or abnormal (cancerous).
Depends. Depends on the physician doing the biopsy. It's a simple procedure. Some physicians use local anesthetic, some use Ethyl Chloride (cold spray), some use nothing at all. Call the physician's office to find out ahead of time how he/she does it so you can anticipate. Good luck.
Depends. For nodules that can be felt, thyroid fna's can easily be done without any anesthetic. Anesthetic injection actually hurts more than a properly performed fna and can cause more bruising and hamper the quality of the specimen. Nodules biopsied under ultrasound often use local as the needle is inserted much longer and is traveling a longer distance because of the transducer.
Gets tissue sample. This technique uses a non invasive ultrasound machine to see where the needle is traveling in the body in order to obtain a sample of tissue. Aspiration usually refers to obtaining fluid from a joint or a mass (cyst) in the body.
Mini Biopsy. The area to be biopsied is visualized with sono. The skin is prepped, the sono probe is covered with a sterile sleeve. Under constant ultrasound guidance, a small bore needle (20g or less) is advanced to the lesion and multiple passes made, usually with the needle hooked up to a syringe with suction applied. Aspirated material is placed in formalin or smeared onto slides to pathology for disgnosis.
Obtain cell samples. A fine needle (25G or 27G size) is inserted into the area of concern, after applying local anesthesia, under continuous real-time ultrasound scanning. Once inside the region of interest, suction is applied while the needle is moved back and forth several times. The needle is then removed and its content spread on a glass slide, which is then "fixed" and "stained' for interpretation.
Minimally invasive. A ct guided fine needle biopsy is performed by an interventional radiologist and in ideal situation will have a cytopathologist evaluating the samples at the bed side. The ct is used to guide the needle to the target to acquire a sample. It is usually done with local but sedation can be used. In the right hands it is a very high yield test.
