Resection of soft tissue sarcoma of the lower limb after evaluation of vascular invasion with intraoperative intravascular ultrasonography.

Background: This study investigated the value of intravascular ultrasonography (IVUS) in the intraoperative assessment of vascular invasion of soft tissue sarcoma.

Methods: In a 4-year interval, of 337 patients with soft tissue sarcoma, 20 patients with tumours of the lower limb in close relation to the neurovascular bundle underwent intraoperative IVUS (20 MHz). Intraoperative findings were correlated with preoperative imaging, histopathological appearance of the resection specimen and patient outcome.

Ductoscopy and intraductal vacuum assisted biopsy in women with pathologic nipple discharge.

Background: Fiberoptic ductoscopy is increasingly used to evaluate pathologic nipple discharge. A major limitation of this technique is the inability to obtain tissue samples from suspicious intraductal lesions. We present a novel technique for ductoscopic biopsy of intraluminal tumors.

Real time 3D (4D) ultrasound-guided percutaneous biopsy of solid tumours.

Purpose: The aim of the current study was to investigate the feasibility of real-time 3D (4D) ultrasound-guided biopsy.

Materials And Methods: Between 2003 and 2005, 53 patients with suspicious lymph nodes or solid tumours underwent 4D ultrasound-guided core needle biopsy using a 4D US-System (Voluson 730, GE/Kretztechnik, Austria). The results were documented prospectively and compared to a matched series of 53 conventional 2D ultrasound-guided core biopsies.
