We performed a percutaneous vertebroplasty at the compressed L2 vertebral body of a 73-year-old female using a left-sided unilateral extrapedicular approach. She complained severe radiating pain and a tingling sensation in her left leg two hours after the vertebroplasty. Spinal computed tomographic scan showed a large retroperitoneal hematoma, and a subsequent spinal angiography revealed a left L2 segmental artery injury. Bleeding was successfully controlled by endovascular embolization. Recently, extrapedicular approaches have been attempted, allowing for the avoidance of facet and pedicle injury with only a unilateral approach. With this approach, however, the needle punctures the vertebral body directly. Therefore, this procedure carries the potential risk of a spinal segmental artery.

During one year period from Sep. 1986 to Sep. 1987, we have experienced 6 cases of infective endocarditis requiring surgical interventions. All 6 patients had class IV or V cardiac disability at the time of surgery. The indication for surgery was rapidly progressive congestive heart failure in all cases. Four patients underwent aortic valve replacement including one double valve replacement. Two other patients required other surgical procedures, removal of large left atrial vegetation mass in one patient and excision of destroyed pulmonary valve and aortic vegetation in the other patient. Two patients died; one of mitral annulus rupture after release of aortic clamp and the other of mediastinal bleeding 3 months after replacement of aortic valve. Three out of 4 survivors are in NYHA Class I and the remaining patient is in Class II. We emphasize that early operative intervention is life-saving in patients with persistent or progressive congestive heart failure, irrespective of the activity of the infective process or the duration of antibiotic therapy.

Transaortic closure of ventricular septal defect, suturing a patch on the morphological right ventricular side in patients with congenitally corrected transposition of great arteries might help to avoid postoperative complete heart block if the aorta is large and the subaortic conus is not well developed. In two patients[aged 6 and 16 years] with congenitally corrected transposition of great arteries, ventricular septal defect, and pulmonary stenosis, transaortic closure of ventricular septal defect was performed. No postoperative complete heart block resulted. One hospital death occurred because of sepsis who had underwent reoperation due to bleeding from the aortotomy site. Minimal aortic regurgitation developed in another patient.

Torso stab injuries near the cardiac box may present unique challenges due to difficulties in hemorrhage control. For a stab injury to the heart, the repair is straightforwardly performed via median sternotomy. In contrast, injuries to the inferior vena cava are challenging to repair, especially when they are close to the diaphragm, and the bleeding can be torrential. Herein, we describe a case of a self-inflicted stab wound within the "cardiac box." The trajectory of the stab injuries went below the diaphragm and injured the infradiaphragmatic inferior vena cava. Successful emergent repair via the thoraco-laparotomy approach revived the young man. In this report, we revisit and discuss previous large series of patients with this rare vena cava injury.

Ampullary tumor is a rare disease whose prevalence rate has increased gradually in recent years with the increase in endoscopic examinations. Ampullary lesions are observed via endoscopy, and biopsy is done to determine whether such lesions are adenomas or carcinomas. Endoscopic papillectomy is performed on ampullary adenomas without intraductal lesions. Before the procedure, bleeding tendencies and pancreatitis are assessed, and the lesion is resected using a high-frequency wave and a thin wire snare. Thereafter, pancreatic duct stent insertion or clipping of the resection site is performed to prevent postprocedural pancreatitis. Although 47-93% of the patients achieve complete endoscopic papillary resection, the recurrence rate is 5-31%. Hence, regular follow-up via endoscopy is required.

In the early days of open heart surgery, acute respiratory failure following extracorporeal circulation was a significant deterrent to an uncomplicated recovery. Although a marked improvement in prevention and treatment of postoperative respiratory failure has been achieved, the problem has not been completely eliminated and continues to be a causative factor in morbidity and mortality Fates following open heart surgery. We have attempted to evaluate postoperative respiratory failure in patients undergoing cardiac operation with the aid of extracorporeal circulation. Our series comprised 92 patients who underwent elective open heart surgery at the Department of Thoracic and Cariodvascular Surgery, School of Medicine, Kyungpook National University, from January, 1980 to December, 1982. In our study, the overall incidence of acute respiratory failure following open heart surgery was 18.8 percent. The duration of extracorporeal circulation in a series of 18 patients who developed postoperative respiratory failure [Group B] was longer in the mean value [120.3 minutes] than the uncomplicated 74 patients [Group A] [85.8 minutes]. The duration of artificial ventilation after open heart surgery in Group A averaged 13.4 hours as contrasted with 76.5 hours in Group B. In Group B, the inspired oxygen concentration [FiO2] in artificial ventilation was continued in the higher level than Group A until 18 hours after operation. Upon pulmonary function test performed pre-and postoperatively, residual volume[RV], RV/TLC and FEV 1.0/FVC were remained essentially unchanged following extracorporeal circulation, whereas forced vital capacity [FVC], FEV 1.0 and FEF 25-75% were significantly decreased in the early postoperative days. The incidence of acute respiratory failure was significantly higher in a series of patients who developed postoperative complications, such as re- exploration due to massive bleeding, low cardiac output, acute renal failure and arrhythmias. A total of 9 patients died, giving an overall mortality was 33.3 percent whereas the mortality was only 1.1 percent for patients without respiratory failure.

Purpose: When hemodynamically unstable patients with blunt major trauma arrive at the emergency department (ED), the safety of performing early whole-body computed tomography (WBCT) is concerning. Some clinicians perform central venous catheterization (CVC) before WBCT (pre-computed tomography [CT] group) for hemodynamic stabilization. However, as no study has reported the factors affecting this decision, we compared clinical characteristics and outcomes of the pre- and post-CT groups and determined factors affecting this decision. Methods: This retrospective study included 70 hemodynamically unstable patients with chest or/and abdominal blunt injury who underwent WBCT and CVC between March 2013 and November 2017. Results: Univariate analysis revealed that the injury severity score, intubation, pulse pressure, focused assessment with sonography in trauma positivity score, and pH were different between the pre-CT (34 patients, 48.6%) and post-CT (all, p<0.05) groups. Multivariate analysis revealed that injury severity score (ISS) and intubation were factors affecting the decision to perform CVC before CT (p=0.003 and p=0.043). Regarding clinical outcomes, the interval from ED arrival to CT (p=0.011) and definite bleeding control (p=0.038), and hospital and intensive care unit lengths of stay (p=0.018 and p=0.053) were longer in the pre-CT group than in the post-CT group. Although not significant, the pre-CT group had lower survival rates at 24 hours and 28 days than the post-CT group (p=0.168 and p=0.226). Conclusions: Clinicians have a tendency to perform CVC before CT in patients with blunt major trauma and high ISS and intubation.

Cardiac surgery is generally followed by a period of routine ventilator support. When the patient seems hemodynamically stable and relatively alert following surgery, respiratory adequacy is tested by the weaning trial. In this study, physiological and clinical prediction of postoperative respiratory adequacy, including values of pulmonary function tests, were examined in an attempt to identity those few variables which predicted the outcome of the ventilator weaning trial following surgery. Our series comprised 27 patients who underwent elective open intracardiac operations at the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Kyungpook National University, from October 1979 to July, 1980. The pulmonary function tests performed on all patients included the following; forced vital capacity [FVC], forced expiratory volume [FEV1.0], forced expiratory flow [FEF 25--75~], residual volume [RV], and functional residual capacity [FRC], measured with a helium dilution technique. Of our 27 patients, 8 were successfully weaned within 20 hours of operation. All patients with cyanotic heart diseases or acquired heart diseases were unsuccessfully weaned. The bypass time in the successful weaning group was shorter in the mean value [82.8 minutes]than in the unsuccessful weaning group [120.5 minutes]. There was a relatively significant difference in the mean values for the two groups in arterial pressure, bleeding amounts and FiO2 among the postoperative monitoring variables, and in forced vital capacity [FVC]. The postoperative clinical assessments appeared vague but corresponded reasonably well to appraisal of success in weaning, especially in variables of cough and self-respiration efforts.

From January 1989 to December 1993, cardiac catheterization and open heart surgery for ventricular septal defect closure were performed in 115 pediatric patients who were selected as meeting the criteria for elective closure of restrictive ventricular septal defect. These criteria included age greater than 1 year and less than 15 years, no evidence of congestive heart failure, Qp/Qs 2.0, pulmonary artery systolic pressure 35mmHg, and no associated cardiac anomalies. Mean age of patients was 5.25$\pm$ 3.53, and 72 patients were male, 43 patients were female[male:female=1.9:1 . Mean systolic pulmonary artery pressure was 19.66$\pm$4.79mmHg, and mean pulmonary to systemic flow ratio was 1.27$\pm$ 0.28. Aortic cusp prolapse was present in 30 patients [26% , aortic insufficiency was present in 1 paient, and 1 patient had prior bacterial endocarditis. There were no instances of complete atrioventricular dissociation, reoperations for bleeding, or reoperations for recurrent ventricular septal defect, but wound infection was present in 1 patient, and there were 7 patients who had the hemodynamically insignificant remnant shunt. There were no early or late deaths or major morbidity.
