Aims and objectives
CT-guided percutaneous core needle biopsy (CNB) is currently used in the diagnostic pathway of pulmonary masses.
The etiology of such pulmonary lesions may vary from benign to malignant course with different options of treatment.
That is why it is necessary to establish a definitive diagnosis.
We cannot forget that CT-guided percutaneous CNB is an invasive procedure that has risks.
Pneumothorax remains the most common complication of lung biopsy with a reported frequency ranging from 14.8% to 54% [1-9].
In addition there is an increase in the number of chest tubes placement,
0,5-7,5% [10] of all lung biopsy procedures and consequently an increased need for hospitalization.
It is the duty of the radiologists to try to decrease the number of complications and make CT-guided lung biopsy a safer diagnostic technique.
A variety of sealing techniques have been studied and can be used during CT-guided lung CNB in order to minimise the frequency of biopsy-induced pneumothorax,
such as instillation of autologous blood clot,
compressed collagen and hydrogel foam plugs,
fibrin glue and saline solution into the biopsy track [10-11].
Normal physiological saline solution provides no adverse reactions,
is inexpensive,
available,
simple to handle and has shown better results in previous studies.
Only two relevant studies [10-11] have been found on the use of this technique and the present work adds to this research.
Therefore,
the purpose of this study was to assess whether saline solution instillation through the coaxial needle track after computed tomography-guided lung biopsy (SSLB) reduces the risk of pneumothorax.
