When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage previously placed and re-do interbody fusion with lower risks compared to revision surgery via previous passage. However, there is still some difficulty in retrieving the interbody cage from the intervertebral space because of no spacious passage, subsidence, and uncontrolled movable cage. In this study, we introduce our experience that we removed failed interbody cage more easily with only the simple additional steps of making a taphole and fixing the cage using a thread-tipped stick.

From Jul.1995 to Oct.2003, at HCM City Blood Transfusion and Hematology Hospital, Hickman catheter was inserted on 41 patients with AML,ALL,BMT,Thalassemia. Main complications were bacterial infections, which accounted for 14,9%. In addition, some events occured accidentally such as chocking up (7,3%), breaking (4,8)% of the cuff in removal of catheter

Methods about removal of intramedullary nail in complicated cases were reported in some literatures but there are no reports about nail removal in the ulna. The authors would like to report such a case and the technique. We removed bone of the inlet site and created another bony window using an osteotome to expose the interlocking screw holes. Only a bony window the size of 2 inter-interlocking holes at the most proximal part of the nail can be used to remove the nail with minimal damage of the triceps brachii tendon and soft tissue.

We experienced a case of the successful retlement of a remnant cutted left atrial pressure catheter found in the left ventricle and ascending aorta on the 67 th day after a mitral valve replacement, using a PTCA guiding catheter and a guide wire.

The central access device is commonly used as a route of chemotherapuetic agents in patients with malignant diseases for its convenient and safety for insertion. This report describes a case of 66-year-old man with colon cancer who suffered a rare complication in which a chemoport embolized into the inferior vena cava and it was successfully retrieved by a percutaneous approach using a goose neck snare.

PURPOSE: A stylet aids intubation as a glottis by changing and maintaining the bending inside the endotracheal tube and is used as an auxiliary device in intubation. The aim of this experimental study is to evaluate resistance differences among endotracheal tube sizes and the usefulness of lubricant for stylet removal. METHODS: Depending on endotracheal tube size and lubricant use status, the subjects were divided into the control (n=10, each 7 tube sizes), lidocaine gel (n=70), and saline groups (n=70). Using a tensile strength meter, the work and the peak withdrawal force consumed for retracting a stylet were measured. RESULTS: When the work dependent on the endotracheal tube size and stylet coating was compared, significantly less work was consumed for 6.0-, 6.5-, 7.0-, 8.0-, 8.5 mm stylet group coated with lidocaine gel (p=0.029, p=0.002, p=0.001, p=0.001, p<0.001, p<0.001) or 6.0-, 6.5-, 8.0-, 8.5 mm stylets coated with saline compared to the control group (p=0.002, p<0.001, p<0.001, and p<0.001). In comparison of the peak withdrawal force dependent on the endotracheal tube size and stylet coating, significantly less peak withdrawal force was consumed for the 6.0- or 8.0- mm stylet group coated with lidocaine gel (p=0.004, p<0.001) or 6.0-, 6.5-, 7.5-, or 8.0 mm stylets coated with saline compared to the control group (p=0.025, p=0.001, p=0.008, and p=0.001). CONCLUSION: We found that the effectiveness of lubricant resulted in various sized tubes. Less work was consumed for five tube sizes (6.0-, 6.5-, 7.0-, 8.0-, 8.5 mm) in lidocaine gel groups and four tube sizes (6.0-, 6.5-, 8.0-, 8.5 mm) in saline groups. Less peak withdrawal force was consumed for two tube sizes (6.0-, 8.0 mm) in lidocaine gel groups and four tube sizes (6.0-, 6.5-, 7.5-, 8.0 mm) in saline groups.
