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...
Methods and materials
This study has been approved by the research ethics committee of our hospital.
In this retrospective matched case-control study we revised the Thoracic Radiology Department database.
This database is updated every time there is an interventional chest procedure recording the procedure and its most relevant characteristics,
including whether serum was used or not when extracting the coaxial needle.
This technique was used for the first time in 2013 by one of the thoracic radiologists and from then on by other two radiologists,
Fifty-six cases and 56 controls were recruited.
The mean age of the sample was 66.1 ± 10.9 years.
The mean lesion size (maximum diameter) was 37.1 ± 25.6 mm.
The mean lesion depth (distance of lung crossed between the pleura and the lesion) was 14.3 ± 15.3 mm.
Primary tumours and metastases were more frequent in the right lung (54/93; 58.1% and 11/13; 84.6% respectively; P = 0.066).
Primary lung tumours and metastases showed a trend to present in different locations,...
Saline solution instillation while removing the coaxial needle in CT-guide lung biopsy is an easy,
effective and cheap strategy as sealant that can help decrease the incidence and severity of pneumothorax.
Pneumothorax is the most common lung biopsy complication after CT-guide lung biopsy.
this safe technique,
with no added risk,
can be recommended and included in the diagnostic pathway for CT-guided lung biopsy.
