Fine-needle aspiration biopsies are very safe minor surgical procedures. Often, a major surgical (excisional or open) biopsy can be avoided by performing a needle aspiration biopsy instead, eliminating the need for hospitalization. In 1981, the first fine-needle aspiration biopsy in the United States was done at Maimonides Medical Center. [1]
Fine-needle aspiration. Fine-needle aspiration (FNA) is a percutaneous ("through the skin") procedure that uses a fine needle and a syringe to sample fluid from a breast cyst or remove clusters of cells from a solid mass. [6] It is mainly used to differentiate between a cyst and a mass. [6]
Fine needle biopsy for cytopathology is also used. [5] [6] [7] Thyroid nodules are extremely common in young adults and children. Almost 50% of people have had one, but they are usually only detected by a physician during the course of a health examination or fortuitously discovered during the investigation of an unrelated condition. [8]
Aspiration sites are marked on the scrotal skin, 5 mm apart according to a template. The number of aspiration sites varies with testis size and ranges from 4 (to confirm obstruction) to 15 per testis (for nonobstructive azoospermia). FNA is performed with a sharp-beveled, 23-gauge, one-inch needle using the established suction cutting technique ...
Typical treatment involves a Needle aspiration biopsy which is typically done with a 10 cc syringe attached to a fine needle aspiration needle. [11] Fine needle aspiration allows retrieval of cytological samples that can be sent for pathological review to determine if the cyst is benign or malignant. [12] Aspirated cysts often recur (come back ...
For cases suspicious enough to proceed to biopsy, small biopsies can be obtained by fine needle aspiration or bronchoscopy are commonly used for diagnosis of lung nodules. [19] CT guided percutaneous transthoracic needle biopsies have also proven to be very helpful in the diagnosis of SPN. [6]
A fine needle aspirate can be done with simply a small bore needle and a small syringe (1 cc) that can generate rapid changes in suction pressure. Fine needle aspirate can be used to distinguish a cystic lesion from a lipoma. Both the surgeon and the pathologist must be familiar with the method of procuring, fixing, and reading of the slide.
In some instances, the mass may have produced local symptoms. This mass is normally referred to a fine needle aspiration biopsy (FNA) for investigation. FNA accuracy is very high and it is a process widely used in these cases. Other investigation methods include ultrasound imaging and nuclear scan.
