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.

Different difficulties can be encountered during removal of an intramedullary femoral nail depending partly upon the design of the nail but mainly on bone ingrowth. This possibility is higher in younger patients and when nail removal is attempted long after initial insertion. We present a case of difficult nail removal. The nail design appears to be important in this problem.

OBJECTIVE: Although previous research has suggested that risk for reoperation among hysteroscopic sterilization (HS) patients is more than ten times higher than for patients undergoing standard laparoscopic tubal ligation, little has been reported about these subsequent procedures. METHODS: This descriptive cohort study used a confidential online questionnaire to gather data from women (n=3,803) who volunteered information on HS followed by device removal surgery performed due to new symptoms developing after Essure placement. RESULTS: In this sample, mean age was 35.6 years and women undergoing hysterectomy after HS comprised 64.9% (n=2,468). Median interval between HS and hysterectomy was 3.7 (interquartile range, 3.9) years and mean age at hysterectomy was 36.3 years. Some patients (n=1,035) sought removal of HS devices and fallopian tubes only, while other miscellaneous gynecological procedures were also occasionally performed for Essure-associated symptoms. When data from all patients who had any post-Essure surgery besides hysterectomy were aggregated (e.g., device removal +“other” cases, n=1,335) and compared to those cases undergoing hysterectomy, mean age was significantly lower than for the hysterectomy group (34.4 vs. 36.3 years, respectively; P<0.01); uterus-conserving surgeries were also typically performed significantly earlier than hysterectomy (P<0.01). CONCLUSION: This investigation is the first to characterize specific gynecological operations after Essure, and suggests that the predominant surgical answer to HS complaints is hysterectomy for many women. Dissatisfaction with HS may represent an important indication for hysterectomy and additional study is needed to quantify this phenomenon.
