Chiba needle

Dr Daniel J Bell and Dr Balint Botz et al.

The Chiba needle is one of the most commonly used biopsy/percutaneous access needles. It is a two-part hollow needle with a beveled tip angled at 30 degrees. The inner stylet (which is also beveled) is removable. The beveling of the Chiba needle results in superior steering compared to conventional trocar needles. It is typically between 18-22 G and is primarily used for aspiration tissue biopsy, to aspirate fluid, and to gain percutaneous access to the biliary tree (e.g. PTC) and pelvicalyceal system of the kidney. It can also be used to puncture and thereby deflate an intravascular balloon if it fails to deflate through its own valve 1,2

History and etymology

The Chiba needle was named after Chiba University in the city of Chiba in Japan. Much of the pioneering work on percutaneous transhepatic cholangiography (PTC) including development of these thin needles was performed by physicians at this institution. The term Chiba needle was first used by the late Allan G Redeker, an American hepatologist, and colleagues in a review article in 1975 3,4.
