Percutaneous ultrasound guided extraction of non-palpable soft tissue foreign bodies.

摘要

Ultrasound is being increasingly used in the diagnosis of the soft tissue foreign body (FB), in particular for the nonradio-opaque materials which may not be visualized with conventional radiography (Fornage & Schernberg 1986). A simple technique for ultrasound guided FB extraction under local anaesthesia is described, and comment is made upon our preliminary experience and pitfalls.
