Aims and objectives
CT is superior radiological method for needle guidance/surveillance in order to achieve sufficient tissue specimens of thoracic lesions.
Our aim was to present variety of patohistological diagnoses established after CT guided biopsies performed during almost eleven months at our department.
Methods and materials
Between November 2016 and October 2017 we performed 73 CT guided transthoracic biopsies aquiring scans with 16-slice CT.
All patients have been recruited by clinicians according to previously taken CT or PET-CT exam,
they were hospitalized and observed at least 24 hours after biopsy.
All patients signed informed consent for the procedure.
Patients were 30-84 years old and male to female ratio was M:F=41:32.
Undetermined lesions of lung parenchyma,
mediastinal and pleural lesions were included in this retrospective study.
Contraindications
Absolute contraindications for transthoracic biopsies...
Results
In 4 out of 73 patients (Fig.
10.) specimen was not obtained due to poor compliance (anxiety,
pain despite local analgesia,
excessive respiratory motions,
inability to reach lesion because of central location).
Pathohistological diagnosis
In 69 patients (Fig.
11.,
12.
and 17.) that underwent transthoracic biopsy,
patohistological results of analised tissue samples revealed 48 neoplastic lesions (14 adenocarcinomas,
6 squamous cell carcinomas,
4 small cell carcinomas,
1 LCNEC, 2 solitary fibrous tumors,
2 mesotheliomas,
2 non-diferentiated non-small cell carcinomas,
12 metastases,
2 lymphomas,
1 lesion...
Conclusion
CT guided transthoracic biopsy is very efficent and safe method obtained to detect possible malignant lesions even in very small nodules and almost in every lung zone.
Complications like pneumothorax and parenchymal hemorrhage,
although relatively often,
in most cases are self-limiting and don´t require any further action.
