The authors report a case of Normal Volume Hydrocephalus with recuring ventricular catheter obstraction treated by bilateral subtemporal craniectomy. Subtemporal craniectomy provide temporary relief from increased intracranial pressure while the same time encouraging dilatation of ventricle, would protect against further catheter obstruction by prevent trapping of catheter tip between the abutting ventricular wall. The patient had been followed-up for 2 years and postoperative result was excellent.

OBJECTIVE: The thromboembolic events during neuroendovascular therapy (NET) are the major complications of concern that can be occasionally fatal. The thrombotic occlusion of the guide catheter for NET is thought to be the risk of the thromboembolic events. We have developed an idea for inventing the monitoring system of the continuous irrigation through the guide catheter. We herein present a unique invention of the guide catheter irrigation monitoring device. METHODS: We have developed ideas for preventing the thrombotic occlusion of the guide catheter. In order to design a convenient device working in the practical use, we have consulted and shared the ideas with the electrical engineers about putting the invention. RESULTS: The guide catheter irrigation monitoring device (GCIMD) consisted of three parts of optical sensor, main body and electric adapter. In brief, the basic principles of working of the GCIMD are as follows. The optical sensor is attached to the dripping chamber of the line to irrigation solution. The main body had the small light and speaker to make an alarm sounds. The sensor monitors the dripping of flush solution. If the dripping stops more than three seconds, a warning alarm has been activated. So, the operating physicians can concentrate and check the guide catheter irrigation. After the use of the GCIMD, there was no major thromboembolic complication in conjunction with the thrombotic occlusion of the guide catheter in our institute. CONCLUSION: We have developed a brilliant invention of the GCIMD for NET.

The aim of this study was to compare peritoneal dialysis catheter insertion by the open method to the laparoscopic method. Twenty four laparoscopic and 10 open peritoneal dialysis catheter placements were performed in children between 2001 and 2008. Patient characteristics, operation related data, procedural complications and clinical outcome were compared. Although there were no cases of catheter obstruction, exit site infection or bleeding in the laparoscopic group, compared to the open method, there was no statistically significant difference between the two groups. Catheter removal rate due to complication was high in the open group and catheter survival rate was high in the laparoscopic group. We concluded that laparoscopic peritoneal dialysis catheter placement is feasible in children of all age groups with at least equivalent functional results compared to the open method. An advantage of laparoscopic catheter insertion is removal of the great omentum and easy fixation of the catheter to the abdominal wall.

Percutaneous transhepatic biliary drainage (PTBD) is an established procedure for biliary obstruction. However, duodenobiliary or jejunobiliary reflux of the intestinal contents through a PTBD catheter sometimes causes recurrent catheter obstruction or cholangitis. A 64-year-old female patient with a history of choledochojejunostomy was referred to our department with acute cholangitis due to choledochojejunal anastomotic obstruction. Emergent PTBD was performed, but frequent obstructions of the catheter due to the reflux of intestinal contents complicated the post-PTBD course. We therefore introduced a catheter with an antireflux mechanism to prevent jejunobiliary reflux. A commercially available catheter was modified; side holes were made at 1 cm and 5 to 10 cm (1 cm apart) from the tip of the catheter, and the catheter was ligated with a nylon thread just proximal to the first side hole. Using this novel "antireflux PTBD technique," jejunobiliary reflux was prevented successfully, resulting in a longer patency of the catheter.

OBJECTIVE: To investigate the therapeutic effects of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome. METHOD: A review of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome was presented with respect to the sleep monitoring results, SF-36 health questionnaire survey, therapeutic effects and complications. RESULT: After operation for 6 months, the patients' sleep Monitoring results were improved remarkably (P<0. 01) and their symptoms of snore or choke got improved. SF-36 health questionnaire survey showed that social function, energy and mental health dimension scores were significantly higher than the preoperative (P<0. 05). There were 18 patients suffered Secondarily bleeding within 2 weeks and 23 patients recrudesced within 1 year. CONCLUSION Radio frequency coblation is an applicable method of therapy for patients with obstructive sleep apnea-hypopnea. The treatments differ with the obstructive location and character of upper airway.

PURPOSE: This study was a retrospective cohort study to evaluate the effect of evidence-based guidelines for catheter dysfunction among hemodialysis patients, Success rate and bleeding complications in catheterization were examined. METHODS: We performed a retrospective cohort study, including 94 patients with catheter dysfunction who were receiving hemodialysis at a university hospital; 55 in the control group and 39 in the protocol group. This protocol was composed of the catheter dysfunction assessment, conservative management of catheter dysfunction, drug management of catheter dysfunction, catheter function test and maintenance management. Data were analyzed with a Chi-square test and t-test using SPSS/WIN 23.0 program. RESULTS: The patency rate of the protocol group was significantly higher than that of the control group. The rate of bleeding complications was not statistically significant for either the control group or the protocol group before or after application. CONCLUSION: The application of the guidelines effectively increased the patency rate of the catheter without bleeding complications. It is hoped that this guideline can be disseminated to nurses nationwide to improve the efficiency of catheter function for hemodialysis patients.

Dynamic left ventricular outflow tract (LVOT) obstruction caused by systolic anterior motion (SAM) of the mitral valve is observed in variable clinical conditions with anatomical or functional abnormalities of LVOT and mitral valve. Several treatment options to relieve obstruction have been suggested including medications to change the contractility of left ventricle, volume reduction of interventricular septum by surgical or non-surgical catheter-based intervention, and surgical correction of the abnormal mitral valve. Here we reported a case of 48-year-old man who presented with shortness of breath. After repeated alcohol septal ablation, mitral valve replacement was finally performed to achieve complete symptom relief.

BACKGROUND: The peritoneal catheter of the continuous ambulatory peritoneal dialysis(CAPD) is patients' lifeline. A significant number of complications and catheter failures in CAPD are due to mechanical problems. We describe our retrospective experience with CAPD focusing on the rate of catheter displacement and survival according to the site of catheter tip placement in 70 cases of CAPD in Kyunghee University Hospital between November 1994 and February 2000. METHODS: We describe our retrospective experience with CAPD focusing on the rate of catheter displacement and survival according to the site of catheter tip placement in 70 cases of CAPD in Kyunghee University Hospital between November 1994 and February 2000. RESULTS: Among 70 cases of CAPD, 46 cases were right pelvic cavity tip placement and 24 cases were left. Causes of chronic renal failure(CRF) were diabetes mellitus in 29 cases(63%), hypertension in 13 cases (28%), glomerulonephritis in 4 cases(9%) in right pelvic cavity catheter tip placement and diabetes mellitus in 13(54%), hypertension in 10(42%), renal tuberculosis in 1 case(4%) left pelvic cavity catheter tip. There were no difference in causative diseases of CRF between both groups. Incidence of CAPD catheter tip displacement were 17.4%(8/46) at right and 4.2%(1/24) at left catheter(p=0.01). Methods for treatment of displacement were fluoroscopic brushing, laparoscopic manipulation and operation. Of the 9 cases, 5 case were received fluoroscopic brushing, 3 case were laparoscopic manipulation and 1 case was received operation. Other complication were peritonitis, catheter obstruction, hernia, death. Overall survival of catheter were 65%(30/46) at right and 71 %(17/24) at left catheter(p=NS). CONCLUSION: The incidence of CAPD catheter tip displacement was higher with catheter tip at the right pelvis than left(p=0.01). But there is no difference in the catheter survival.

Autonomic dysreflexia is a clinical emergency syndrome of uncontrolled sympathetic output that can occur in patients who have a history of spinal cord injury. Despite its frequency in spinal cord injury patients, central nervous system complications are very rare. We report a man with traumatic high level incomplete spinal cord injury who suffered hypertensive right thalamic hemorrhage secondary to an episode of autonomic dysreflexia. Prompt recognition and removal of the triggering factor, the suprapubic catheter obstruction which led to hypertensive attack, the patient had a favorable functional outcome after the resorption of the hematoma and effective rehabilitation programme.
