Aims and objectives
Fine Needle Aspiration Biopsy (FNAB) technique uses 20-25G needles without local anesthesia to obtain samples.
FNAB can be performed with manual or automatic aspiration without differences in the quality of the samples Automatic techniques are easier and more precise (1)
Cells obtained with FNAB are often enough to determine the malignancy of the tumour,
the histological grade and its origin.
However,
there are organs and pathologies in which is necessary to preserve the architecture of the tissue and to perform immunohistochemical and genetic analysis.

Methods and materials
A retrospective study of Fine Needle Aspiration Biopsy (FNAB) technique was performed in 49 patients of our center (Hospital Vall d'Hebron of Barcelona),
obtaining a total of 52 samples over a two-year period (February 2016 to February 2018).
In 3 of the patients the technique was performed in 2 different locations.
Two ultrasound Systems were used: Siemens Acuson S2000 and Esaote MyLab Twice and 20G Hepashot needles (Fig. 7)
The different reasons for performing FNAB in these patients were:
● Small injuries
● Injuries in...
Results
There are maneuvers that we proposed to improve tissue sampling when using Menghini tip needles (Fig. 8,Fig. 9,Fig. 10)
The mean age of the patients was 63.4 years (median 63 years,
minimum age 28 and maximum 88 years).
Biopsies were performed on 32 men (65% proportion) and 17 women (35%).
The mean size of the lesions was 17.9 mm and median 14 mm ranged from 5 mm to 43 mm)
52 lesions were biopsied in a total of 49 patients (3 patients were biopsied in...
Conclusion
FNAB with Menghini tip is an easy,
effective and safe alternative to CNB with Tru-cut® to obtain histological samples of small sized lesions located near important structures,
especially in cervical spaces.
It has a wide range of applications (breast,
liver,
thyroid gland,
lymph nodes...)
