Results
- The average size of lesions with FNA only biopsies was 28 mm, compared to 40 mm for FNA and core biopsies.
- 11 of 17 (64.7%) FNA-only biopsies and 29 of 34 (85.3%) combined FNA and core tissue biopsies had a definitive histological diagnosis.
- The most common malignant diagnosis was adenocarcinoma of the lung.
- 31 out of 51 (60.8%) patients developed post-procedural pneumothorax. This included 15 of 17 (88.2%) patients of the FNA only group and 16 of 34 (47.1%) of the combined FNA and core biopsy group.
- 8 of 15 patients in the FNA only group required aspiration of pneumothoraces; 3 of these subsequently required chest drain insertion. 2 of 16 patients in the combined FNA and core biopsy group required aspiration of pneumothoraces, none required chest drains.
- 2 (11.8%) patients in the FNA-only group and 1 (2.9%) patient in the FNA and core biopsy group developed mild pulmonary haemorrhage on post procedural CT. No further complications were observed.
