Diagnostic interventional procedures of small liver lesions under ultrasound control

Purpose: The present study assess factors affecting the success of US -guided liver biopsy of small focal lesions on the basis of experience when cytopathologic examination results were available. Material and methods: 135 fine-needle liver biopsies and punctures in 135 patients (80 male and 55 female) were performed under US control. Lesions ranged in diameter from 9 mm to 20 mm. We utilized US guidance in 123 (91.11%) cases and CT guidance in 12 (8.88%) cases. Ultrasound equipment supplied with 3.5 and 7 MHz linear and convex transducers and biopsy needles were used. The on-site cytologic evaluation guided the…
