Monocular Motion Parallax in Percutaneous Transhepatic Biliary Drainage
Abstract
Purpose was the evaluation of possibility of using monocular motion parallax (MTD) in navigation during percutaneous transhepatic cholangiostomy. Materials and Methods. To study the MTD the phantom of bile ducts was created. It consists of two plastic tubes, upper tube marked with radiopaque marker and the needle installed between the tubes. Interventions were performed on 155 patients in 3.5 years. Drainage of left lobe ducts was performed on 15 (9.6%) patients, drainage of right lobe ducts was performed on 84 (54.2%), drainage of both right and left lobes was performed on 56 (36.2%) patients. Results. Application of MTD in navigation during percutaneous transhepatic cholangiostomy allowed to increase the number of simultaneous multiple drainage ducts of both left and right hepatic lobes from 2 patients in 2011 to 12 patients in 2012. Conclusions. Monocular motion parallax allows quickly get an idea of needle position in bile ducts on different types of C-arms and, if necessary, make corrections of puncture direction, reduce the time and traumatism of this manipulation.
