Implanting a pacemaker is the most often used intervention for treating bradycardia. The most commonly used pacemaker is the intracardiac pacemaker, yet it can have many complications. An infected pacemaker can spread to systemic infection and the condition of the patient can quickly get worse, so if an infected pacemaker is suspected, then the pacemaker must be removed. Apart from the use of interventional methods such as a loop or a weight, we can take a more aggressive approach by using extracorporeal circulation for removal of the pacemaker. We report here on two cases in which extracorporeal circulation was used to remove the infected pacemakers.

Patients with impaired ability to eat require nutritional support enterally or parenterally. Gastrostomy is a preferred method because total parenteral nutrition has many complications and high cost. Surgical gastrostomy has been a traditional and well-established method prior to the development of percutaneous gastrostomy. Since then, percutaneous gastrostomy has been established as an effective, safe, easy technique with a low morbidity and mortality rate. Consequently, percutaneous gastrostomy has been the first method for long-term enteral nutrition. The purpose of this review is to describe the techniques, indications, complications of percutaneous radiologic gastrostomy/gastrojejunostomy and to compare with endoscopic method.

IVR procedures are on the rise, and patient doses are on the rise. It is necessary to evaluate fluoroscopy dose in IVR procedure. Evaluate ESD on IVR equipment as a reference to DRL settings, I would like to present the direction of improvement in the ESD rate test criteria for fluoroscopy dose. The experimental method is measured with 6cc ionization chamber under the 20cm PMMA Phantom. Radiation is subject to abdominal procedure. The average dose rate of the incident surface was 21.6 ± 11.4 mGy/min. The highest dose equipment was 58.5 mGy/min, and there was no equipment exceeding the domestic standard of 100 mGy/min. However, there were five units above 50 mGy/min. To reduce fluoroscopy dose, it is recommended to reduce pulse rate, The dose increases as the image receptor ages. It is recommended to modify the domestic inspection criteria to 50 mGy/min.

Extracorporeal shockwave therapy has been widely spread out showing an excellent efficacy compared to traditional medicinal treatments, interventional procedures or surgeries for diseases of tendons and musculoskeletal system. Major performance tests of extracorporeal shockwave therapy consist of pressure, energy flux, concentration, and effective amount of energy on the focus area of shockwave according to IEC 61846. Shockwave should be irradiated accurately to the lesion area to improve the performance of extracorporeal shockwave therapy, which makes it necessary to add the relevant section, IEC 60601-2-36 (12.1.101. Precision of Target Markers and Target Locations). International standards of extracorporeal shockwave therapy have been prepared based on European and western people. Thus, we need to conduct many studies on Korean patients to improve the quality of extracorporeal shockwave therapy and to develop the medical industry. In addition, the performance evaluation of extracorporeal shockwave therapy which has been prepared according to international standards should be additionally modified and supplemented corresponding to the Korean circumstances.

This review was described to investigate the feasibility of using ultrasound as an image tool for interventions of lumbar spine. This article will first provide an overview of lumbosacral spine surface anatomy and sonoanatomy. A detailed understanding of anatomy is critical for interpretation of ultrasound and procedural performance at spine. Fluoroscopy is most commonly used in interventional spine procedures, but radiation exposure is the major concern when obtaining fluoroscopic images. Ultrasound is radiation-free, is easy to use, and can provide real-time images with high accuracy. Also this device can be used in virtually any clinical setting. Ultrasound guidance offers a reliable alternative to fluoroscopy or computed tomography for lumbar interventions and can be safely performed without radiation exposure.

Purpose: This study of this study was to identify factors influencing the burden of main family caregivers who take care of elderly patients with brain and spinal diseases. Methods: This was conducted as descriptive research and data were collected from 255 main family caregivers who were taking care of elderly patients with brain and spinal diseases from 4 hospitals in Daegu and Gyeongbuk Province. Stepwise-multiple regression was used to identify the influencing factors of burden felt. Results: As the score of burden felt by the main family, economic, social, physical, interdependent and emotional burdens were high in order. Factors influencing burden felt by main family care givers taking care of elderly patients with brain and spinal diseases were changed relation with patient after hospitalization, daily life ability, marital status, education and family caregiver's personality (explanatory power of 24.6%). Family caregivers felt a heavier burden when their relation with the patient was changed negatively or when the patient's activity of daily living was low. Conclusion: Based on these results, we need to develop coping measures and interventional programs for reducing the burden felt by the main family caregivers of elderly patients with brain and spinal diseases.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Cryosurgery is a safe method for palliation of endobronchial malignancies causing airway obstruction. Due to its simplicity and effectiveness for controlling bleeding, endobronchial cryosurgery is considered to be a good method that is clinically applicable to a malignant endobronchial tumor. In cases with stenosis caused by an endoluminal tumor, cryo-recanalization with a cryoprobe was immediately effective in most of the patients. A novel technique described by Hetzel in 2004 to achieve rapid recanalization of central airway obstruction with endobronchial cryoprobe. Cryorecanalization technique is feasible and offers many advantages in the interventional therapy of malignant intraluminal tumors of the respiratory tract.
