EXCISIONAL BIOPSY OF IMPALPABLE SOFT-TISSUE TUMORS - US-GUIDED PREOPERATIVE LOCALIZATION IN 12 CASES

We present a technique to facilitate excisional biopsy of impalpable s oft tissue tumors. A modified Kopans localization needle is positioned preoperatively under ultrasound-guidance (7.5 MHz). The needle contai ns a hookwire with an over-bent hook that springs open when protruded beyond the needle tip and anchors the wire in the lesion. The techniqu e was used in 12 patients and facilitated excisional biopsy in all of them.
