We reviewed 9 cases of pyogenic spondylodiscitis following percutaneous endoscopic lumbar discectomy (PELD). Microbiologic cultures revealed 6 causative organisms. Five patients were managed conservatively and four were treated surgically. The mean follow-up period was 20.6 months and the average length of hospitalization was 24 days. Radiological evidence of spinal fusion was noted and infection was resolved in all patients. Although PELD is a safe and effective procedure, the possibility of pyogenic spondylodiscitis should always be considered.

Percutaneous epidural neuroplasty (PEN) is a known interventional technique for the management of spinal pain. As with any procedures, PEN is associated with complications ranging from mild to more serious ones. We present a case of intracranial subdural hematoma after PEN requiring surgical evacuation. We review the relevant literature and discuss possible complications of PEN and patholophysiology of intracranial subdural hematoma after PEN.

Vascular complications after percutaneous angiography include hematoma, pseudoaneurysm, arteriovenous fistula, thromboembolism, arterial laceration and infection. Hematomas may occur in the groin, thigh, retroperitoneal, intraperitoneal, or abdominal wall. A 54-year-old female underwent percutaneous transfemoral angiography for the evaluation of cerebral aneurysm. Renal subcapsular hematoma developed 3 hours after the procedure. Renal subcapsular hematoma after percutaneous angiography is very rare. We investigated the possible causes of renal subcapsular hematoma. To avoid this rare complication, we need to perform guide-wire passage carefully from the beginning of the procedure under full visual monitoring.

Stent thrombosis is a rare complication after percutaneous coronary intervention (PCI), but it might be related to fatal outcomes. We report a case of patient who suffered from acute myocardial infarction complicated with cardiogenic shock and ventricular tachycardia caused by stent thrombosis and successfully resuscitated by percutaneous cardiopulmonary bypass support.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.

Percutaneous vertebroplasty is a relatively easy and minimally invasive procedure used in treating vertebral fractures. However, the procedure has many complications, one of which is bone cement leakage, which happens frequently. Leakage to the paravertebral venous system, in particular, may lead to especially devastating consequences. Here we report a case of a 65-year-old male patient with an intracardiac foreign body (bone cement) that generated a perforation on the right ventricle, and result in hemopericardium after percutaneous vertebroplasty. We performed open heart surgery to remove the foreign body.

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 endoscopic gastrostomy tube placement is often performed in patients with a ventriculoperitoneal shunt and it has been accepted as a safe procedure. The authors report a case of a 50-year-old male who developed acute exacerbation of the hydrocephalus immediately after the percutaneous endoscopic gastrostomy tube placement without any signs of shunt infection, which has not been reported until now. After revision of the intraperitoneal shunt catheter, the sizes of the intracranial ventricles were normalized.

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.

This study was carried out to examine stability of biological products(BCG vaccine), freeze-dried BCG vaccine for percutaneous use and for interdermal use.1. pH tests of freeze-dried BCG vaccine for percutaneous use and for interdermal use vaccine was suited to basic range with variable temperature. freeze-dried BCG vaccine for percutaneous use was resulted with 6.2-6.7 and for interdermal use was resulted with 6.2-6.7.2. Bacterial concentration test of freeze-dried BCG vaccine for percutaneous use and for interdermal use vaccine was suited to basic range with variable temperature. (omitted)
