The totally implantable venous port device is used in patients undergoing chemotherapy. The complications associated with this device include venous thrombosis, infection, catheter fracture, extravasation, and intravascular dislodgement. The incidence of port catheter dislodgement is low. The treatment of choice for port dislocation involves immediate retrieval of the distal migrated part, and percutaneous transcatheter retrieval is regarded as the standard method. A 40-year-old female presented with intermittent palpitation. She was referred from the Department of General Surgery after detection of a fractured and dislocated implantable venous port system into the main pulmonary artery. We successfully retrieved the dislocated fractured device using a 5-Fr pigtail catheter and snare catheter. We herein report this case with a literature review.

Whether indwelling urethral catheter should be removed after urethroplasty or visual internal urethrotomy in patients with posterior urethral injured is still controversial. From May 1990 to February 1995, 28 patients with posterior urethral injury underwent retrograde pericatheter urethrography for the purpose of the evaluation of urethral continuity in the timing of the removal of indwelling urethral catheter. The indwelling catheter was removed in 24 patients whose urethra did not have any extravasation, and 4 patients had detectable extravasation. We conclude that retrograde pericatheter urethrogram is the most useful radiologically diagnostic method to evaluate in the timing of the removal of indwelling urethral catheter and to obtain the objective parameter of urethral patency in posterior urethral injured patients, postoperatively.

PURPOSE: The tunneled hemodialysis catheter has been widely used for a temporary or an alternative permanent vascular access in patients requiring hemodialysis. The tunneled hemodialysis catheter is also widely used for a reliable vascular access in children who need stem cell transplantation. METHOD: We reviewed the results of 150 catheters inserted in 108 patients for the duration of the indwelling catheter, the complication rate and the reasons for insertion and removal. RESULT: The mean duration of the indwelling catheter was 5.7 months (1 d~52.2 mo). In the stem cell transplantation group, the mean duration of the indwelling catheter was significantly longer than for the hemodialysis group (mean: 9.9 mo vs. 3.6 mo, P<0.05). Fifty-one catheters (39.8%) were removed due to complications. The most common complications were infection (n=23: 17.9%) and dislocation (n=15: 11.7%). In the hemodialysis group, the complication-related catheter removal was more frequent than in the stem cell transplantation group (43.9% vs. 32.6%, P<0.05). CONCLUSION: The tunneled hemodialysis catheter remains a reliable short-term vascular access for hemodialysis and a good vascular access in stem cell transplantation.

PURPOSE: To evaluate the usefulness and safety of the placement of an implantable chemoport via external jugular vein as a primary route for chemotherapy. MATERIALS AND METHODS: Between January 2006 and June 2007, a total of 108 implantable chemoports were placed on 325 patients for chemotherapy via the external jugular vein as a primary route. We placed a 9.6 F single lumen chemoport using a surgical procedure (n=89) and an interventional procedure (n=19), and evaluated the duration of catheterization days and treatment complications. RESULTS: An implantable chemoport was successfully installed in all cases. Furthermore, the duration of catheterization ranged from 2 to 461 days (mean: 187 days, total catheter days: 21,994). In addition, a total of 85 chemoports were removed due to complications (n=7) and termination of chemotherapy (n=78). A transient pulmonary air embolism occurring during a procedure was observed in one case. No pneumothorax or catheter malpositions were observed in the study subjects. Two chemoports were removed two days after implantation due to persistent tachycardia. In addition, five late complications occurred, which resulted in catheter occlusion (3 cases) (3%, 0.14/1000 catheter day) and infection in (2 cases) (2%, 0.09/1000 Catheter days). Lastly, no symptoms were attributed to a central vein thrombosis. CONCLUSION: The results of this study suggest that the implantation of chemoports via the external jugular vein is a safe procedure. Moreover, the selection of the external jugular vein as a primary route is useful in determining chemoport insertion locations.

BACKGROUND: Surveillance and interventions of central line-associated bloodstream infections (CLABSIs) had mainly been targeted in intensive care units (ICUs). Central lines are increasingly used outside ICUs. Therefore, we performed a hospital-wide survey of CLABSIs to evaluate the current status and develop strategies to reduce CLBASI rates. METHODS: All hospitalized patients with central venous catheters (CVCs) were screened for CLABSIs from January 2014 through December 2015 at a 1,328 bed tertiary care teaching hospital in Korea using an electronic data-collecting system. Clinical information including type of CVC was collected. CLABSI rates were calculated using the definitions of the National Health and Safety Network after excluding mucosal barrier injury laboratory-confirmed bloodstream infection (BSI). RESULTS: A total of 154 CLABSIs were identified, of which 72 (46.8%) occurred in general wards and 82 (53.2%) in ICUs (0.81 and 2.71 per 1,000 catheter days), respectively. Non-tunneled CVCs were most common (68.6%) among 70 CLABSI events diagnosed within one week of their maintenance. On the other hand, tunneled CVCs and peripherally inserted central catheters (PICCs) were more common (60.5%) among 114 CLABSI events diagnosed more than a week after maintenance. Whereas the majority (72.2%) of CLABSIs in ICUs were associated with non-tunneled CVCs, tunneled CVCs (38.9%) and PICCs (36.8%) were more common in general wards. CONCLUSION: CLABSIs are less common in general wards than in ICUs, but they are more often associated with long-term indwelling catheters. Therefore, interventions to prevent CLABSIs should be tailored according to the type of ward and type of catheter.

According to the clinical requirements of cardiopulmonary bypass surgery, this paper established a simulation system for cardiac surgery which consists of venous reservoir, variable balance chamber, blood suction bag, ventricle suction bag, resistance valves, pressure gauges and tubings. Using the proposed system, perfusionists can mimic the implementation of pre-established surgery strategy, predict various abnormal conditions in the operation, and accordingly take the urgent actions so as to improve the success rate of surgery and to ensure the safety of patients.

BACKGROUND: Despite the importance of burn-induced encephalopathy, cerebral hemodynamics after burn injury and during resuscitation remains undefined. The aim of our study was to evaluate the effects of a large cutaneous burn injury on the cerebral circulation. METHODS: Anesthetized sheep(n=8) were prepared with vascular catheters, a urinary catheter and a Richmond bolt for intracranial pressure monitoring. A scald injury was inflicted on 70% of total body surface area with hot water. Resuscitation was started 30 minutes after scald with Ringer's lactate to restore and then maintain baseline oxygen delivery. Resuscitation maintained blood pressure, cardiac output and urine output at normal levels. Brain blood flow was measured with colored microspheres. RESULTS: During resuscitation intracranial pressure rose slowly from 10.6+/-1.5 to 17.0+/- 4.0 mmHg(P<0.05) and cerebral perfusion pressure was reduced from 86.4+/- 6.8 to 64.1+/- 2.8 mmHg(P<0.05). During early resuscitation cerebrovascular resistance declined to maintain brain blood flow and oxygen delivery at baseline or better. After 6 hours, cerebrovascular resistance was inappropriately increased during a period of reduced cerebral perfusion pressure which resulted in brain blood flow being half the baseline levels. CONCLUSIONS: These data suggest that autoregulation maintains brain blood flow immediately after burn shock and early resuscitation, but autoregulation may be less effective as burn resuscitation proceeds.
