Objective : Percutaneous vertebroplasty has recently been introduced as an interesting therapeutic alternative for the treatment of thoracolumbar vertebral body fractures in elderly persons with osteoporosis. The authors present the early results of this method. Method and Material : From July 1999 to April 2000, percutaneous transpedicular technique was used in 20 patients (2 men and 18 women) whose mean age was 67.5 years old(range 59-79) with painful vertebral compression(22) and burst(2) fractures. The interval between fracture and vertebroplasty ranged 1 day to 4 months. The procedure involved percutaneous puncture of the injured vertebra via transpedicular approach under fluoroscopic guidance, followed by injection of polymethylmetacrylate(PMMA) into the vertebral body through a disposable 11-guage Jamshidi needle. Result : The most common cause of fracture was slip down and the most frequent injured level was the twelfth thoracic spine. The procedure was technically successful bilaterally in 18 patients(9 thoracic and 15 lumbar spines) with an average injection amount of 7.7ml PMMA in each level. Seventeen(94.4%) patients reported significant pain relief immediately after treatment. Two leaks of PMMA were detected with postoperative CT in spinal epidural space and extravertebral soft tissue without clinical symptoms. Conclusion : Although this study represents the early results, percutaneous vertebroplasty seems to be valuable tool in the treatment of painful osteoporotic vertebral body fractures in elderly, providing acute pain relief and early mobilization.

Microvascular decompression is the gold standard for the treatment of trigeminal neuralgia (TN). However, percutaneous techniques still play a role in treating patients with TN and offer several important advantages and efficiency in obtaining immediate pain relief, which is also durable in a less invasive and safe manner. Patients' preference for a less invasive method can influence the procedure they will undergo. Neurovascular conflict is not always a prerequisite for patients with TN. In addition, recurrence and failure of the previous procedure can influence the decision to follow the treatment. Therefore, indications for percutaneous procedures for TN persist when patients experience idiopathic and episodic sharp shooting pain. In this review, we provide an overview of percutaneous procedures for TN and its outcome and complication.

Surgical treatment of the degenerative disc disease has evolved from traditional open spine surgery to minimally invasive spine surgery including endoscopic spine surgery. Constant improvement in the imaging modality especially with introduction of the magnetic resonance imaging, it is possible to identify culprit degenerated disc segment and again with the discography it is possible to diagnose the pain generator and pathological degenerated disc very precisely and its treatment with minimally invasive approach. With improvements in the optics, high resolution camera, light source, high speed burr, irrigation pump etc, minimally invasive spine surgeries can be performed with various endoscopic techniques for lumbar, cervical and thoracic regions. Advantages of endoscopic spine surgeries are less tissue dissection and muscle trauma, reduced blood loss, less damage to the epidural blood supply and consequent epidural fibrosis and scarring, reduced hospital stay, early functional recovery and improvement in the quality of life & better cosmesis. With precise indication, proper diagnosis and good training, the endoscopic spine surgery can give equally good result as open spine surgery. Initially, endoscopic technique was restricted to the lumbar region but now it also can be used for cervical and thoracic disc herniations. Previously endoscopy was used for disc herniations which were contained without migration but now days it is used for highly up and down migrated disc herniations as well. Use of endoscopic technique in lumbar region was restricted to disc herniations but gradually it is also used for spinal canal stenosis and endoscopic assisted fusion surgeries. Endoscopic spine surgery can play important role in the treatment of adolescent disc herniations especially for the persons who engage in the competitive sports and the athletes where less tissue trauma, cosmesis and early functional recovery is desirable. From simple chemonucleolysis to current day endoscopic procedures the history of minimally invasive spine surgery is interesting. Appropriate indications, clear imaging prior to surgery and preplanning are keys to successful outcome. In this article basic procedures of percutaneous endoscopic lumbar discectomy through transforaminal and interlaminar routes, percutaneous endoscopic cervical discectomy, percutaneous endoscopic posterior cervical foraminotomy and percutaneous endoscopic thoracic discectomy are discussed.

Percutaneous coronary intervention including intracoronary stenting is currently an accepted treatment modality in the treatment of coronary artery disease and is widely performed to treat the patient with multivessel disease with decreased morbidities and less cost compared with conventional coronary rtery bypass grafting(CABG), Repeated interventions due to restenosis even after successful angioplasty are the major disadvantage of the angioplsty especially when the lesion is located inthe left anterior descending artery(LAD) Recently CABG through left anterior small thoracotomy using the left internal thoracic artery to revascularize the LAD territory without cardiopulmonary bypass so called Minimally Invasive Direct Coronary Artery Bypass(MIDCAB) was intrduced and performed with comparable early outcomes. In this regard the integrated approach with percutaneous coronary intervention and minimally invasive direct coronary artery bypass surgery so called 'Hybrid CABG' was suggested to be an effective treatment in suitable patients with multivessel coronary artery disease. We report three cases of Hybrid CABG.

Facet joint synovial cysts are uncommon intraspinal abnormalities, which appear to be secondary to degenerative changes of the joints. They can cause chronic back pain and radiculopathy, as shown in spinal stenosis. When symptomatic cysts fail to respond to conservative measurements, surgical decompression is known as the standard treatment. Percutaneous steroid injections, and distension of the cysts under fluoroscopic guidance, may be a minimally invasive treatment option. Here, the case of a patient with a symptomatic L5-S1 facet joint synovial cyst and left S1 radiculopathy, who responded satisfactorily to percutaneous treatment, is presented.

Purpose: The purpose of this study was to investigate the effects of a smoking cessation education for patients with percutaneous coronary intervention. Methods: The study was a quasi-experimental study with a non-equivalent control group non-synchronized design. The Sixty subjects were assigned to either the treatment group. The treatment intervention was a onetime program during hospitalization. Data were collected during several time periods: before treatment, immediately after treatment, two weeks later, and one month after the treatment. Data were analyzed with the SPSS 14.0 program with an independent t-test, $x^2$ test, repeated measures ANOVA. Results: There were significant differences between the two groups in terms of knowledge and attitude. The significance was absent for the testing two weeks post group intervention and then one month later the significance was again detected in the amount of smoking and smoking behavior. Conclusion: The results of this study suggest that smoking cessation education could be utilized for inpatients with percutaneous coronary intervention as nursing intervention in hospitals effectively. Further research is recommended in order to understand the change in significance in the different time periods.

Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.

This data mining technique was used to extract useful information from percutaneous coronary intervention data obtained from the US public data homepage. The experiment was performed by extracting data on the area, frequency of operation, and the number of deaths. It led us to finding of meaningful correlations, patterns, and trends using various algorithms, pattern techniques, and statistical techniques. In this paper, information is obtained through efficient decision tree and cluster analysis in predicting the incidence of percutaneous coronary intervention and mortality. In the cluster analysis, EM algorithm was used to evaluate the suitability of the algorithm for each situation based on performance tests and verification of results. In the cluster analysis, the experimental data were classified using the EM algorithm, and we evaluated which models are more effective in comparing functions. Using data mining technique, it was identified which areas had effective treatment techniques and which areas were vulnerable, and we can predict the frequency and mortality of percutaneous coronary intervention for heart disease.

Percutaneous first annular pulley (A1 pulley) release, which has been increasingly used to treat trigger fingers, has been widely established as a safe and simple procedure. Multiple studies have reported positive results of percutaneous A1 pulley release. In this study, however, we report cases of patients who developed complications after undergoing percutaneous A1 pulley release at local clinics. A total of six patients visited our hospital for infectious complications after percutaneous A1 pulley release. Various sequelae such as damage to normal structures, insufficient procedure, and tissue necrosis were observed during the exploration. A retrospective study was conducted to identify the cause and trend of the observed complications by instruments (HAKI knife or needle). In the HAKI knife group, there was a tendency for damage to normal structures, while in the needle group, an insufficient release or serious soft tissue necrosis was observed. Based on these cases, our findings confirm the existence and characteristics of infectious complications following the percutaneous A1 pulley release. We further identify that the type of instrument used predicts the nature of complications. Thus, reliable and skilled performance of the procedure by experts is essential for safe treatment.
