Abstract
BACKGROUND AND AIMS: Despite their usefulness, CT-guided procedures have a low profile in Romania. The current study has the purpose of describing a first experience in performing these procedures. METHODS: Tumors and fluid collections that were inaccessible for biopsy or drainage by ultrasound or endoscopic guidance were included. The procedures were performed using a 64-slice GE Optima CT660 CT scanner. The biopsies were carried out using the coaxial technique with an 18 G semiautomatic needle. The drainages were performed using 10 F pig-tail drains that were inserted using the Seldinger technique. Data regarding the size and location of the target lesion, puncture technique, success and complication rates were recorded. RESULTS: Between May 2017 and April 2018, 30 procedures were performed, of which 26 biopsies and 4 drainage insertions. Of the biopsies 3 were mediastinal, 8 pulmonary, 6 retroperitoneal, 4 pelvic, and 5 of the bone. The drainages were performed for pelvic lymphoceles. The average lesion size was 3.2 cm (0.7-9 cm), with a depth from the skin of 9.1 cm (0.6-15.2 cm). The average procedure duration was 58 minutes (31-93 minutes). A conclusive histopathological diagnosis was set after 92.3% of biopsies. Three procedures resulted in complications, two being minor (hemothorax, soft tissue hematoma) and one severe (tension pneumothorax requiring drainage). CONCLUSIONS: CT guidance offers safe access to lesions that cannot be biopsied or drained under ultrasound or endoscopic guidance.
