Percutaneous Retrieval of Foreign Bodies Around Vital Vessels Aided with Vascular Intervention: A Technical Note.

Objective: To describe a new interventional technique to remove foreign bodies (FBs) embedded in soft tissues around vital vessels.

Methods: Under fluoroscopic guidance and using local anesthesia, percutaneous removal of FBs was performed using forceps in nine patients. All patients suffered from a metallic soft tissue FB located in close proximity to important vessels and one also had a small traumatic pseudoaneurysm adjacent to the FB.

Diversity in early crustal evolution: 4100 Ma zircons in the Cathaysia Block of southern China.

Zircons are crucial to understanding the first 500 Myr of crustal evolution of Earth. Very few zircons of this age (>4050 Ma) have been found other than from a ~300 km diameter domain of the Yilgarn Craton, Western Australia. Here we report SIMS U-Pb and O isotope ratios and trace element analyses for two ~4100 Ma detrital zircons from a Paleozoic quartzite at the Longquan area of the Cathaysia Block.

Value of 3-dimensional CT virtual anatomy imaging in complex foreign body retrieval from soft tissues.

Objective: To investigate the value of 3-dimensional (3D) CT virtual anatomy imaging (VAI) in the complex foreign body (FB) retrieval of the soft tissues.

Materials And Methods: Four hundred and seventy-five patients with radiopaque FB(s) diagnosed by radiograph underwent contrast-enhanced 3D CT examination. VAI was reconstructed by volume-rendering opacity software, by sliding down the lowest threshold from -600 to 100 HU.

Novel methods of removing metallic foreign body from human soft tissue: a report of 7390 cases.

Background: We studied methods of locating metallic foreign bodies in soft tissue of the human body.

Methods: Using a three-dimensional (3D) locator, we removed metallic foreign bodies precisely from soft tissue of 7390 patients through magnetic forceps between June 1999 and June 2009.

Results: In 7390 patients, we successfully removed 99.
