A 67-year-old female presented to the emergency department with complaints of dyspnea and chest wall pain after a fall from a cultivator. Initial chest CT showed multiple left rib fractures, a loculated hematoma without active bleeding, and hemothorax. On the third day of admission, the chest X-ray showed an abrupt aggravation of haziness and the chest CT showed that the size of the hematoma had increased with active bleeding from the pulmonary artery. In cases of loculated hematomas adjacent to the hilum on CT scan, the diagnosis of pulmonary artery injury should be considered.

A 69-year-old male was admitted for dyspnea and chest pain. The patient had undergone coronary artery bypass graft surgery and tube thoracostomy three years ago. The chest radiograph showed pleural effusion, which was drained using a percutaneous catheter with CT guidance. However, residual pneumothorax was observed four days later. Despite insertion of the 12 Fr trocar-type tube, pneumothorax did not improve and air leaks were observed. Chest CT showed that the tube was placed in the left main bronchus. After removal of the tube, the patient recovered uneventfully from pulmonary hemorrhage and bronchial perforation without complications.

The shortage of available organ donors is a significant problem and various efforts have been made to avoid the loss of organ donors. Among these, extracorporeal membrane oxygenation (ECMO) has been introduced to help support and manage potential donors. Many traumatic brain injury patients have healthy organs that might be eligible for donation for transplantation. However, the condition of a donor with a fatal brain injury may rapidly deteriorate prior to brain death determination; this frequently results in the loss of eligible donors. Here, we report the use of venoarterial ECMO to support a potential donor with a fatal brain injury before brain death determination, and thereby preserve donor organs. The patient successfully donated his liver and kidneys after brain death determination.

This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. The tooth of the first case was extracted because of severe bone destruction. The palato-gingival groove of the second case was eliminated using a round bur, and the resulting defect was filled with synthetic graft and covered by an absorbable membrane. Both diagnosis and treatment of palato-gingival groove were very difficult and usually extraction of the involved tooth is the treatment of choice, but combined endodontic-periodontic treatment allowed the tooth to be saved.

BACKGROUND: Maintenance of adequate vascular access for hemodialysis is important in patients with end-stage renal disease. Once arteriovenous fistula (AVF) occlusion occurs, the patient should be treated with rescue therapy. This study was performed to evaluate the results of a rescue therapy for AVF occlusion. METHODS: From January 2008 to December 2012, 47 patients who underwent surgical rescue therapy for AVF occlusion after graft AVF formation, were enrolled in this study. The patients were divided into two groups, namely the graft repair group (group A, n=19) and the thrombectomy group (group B, n=28). Postoperative results of both groups were analyzed retrospectively. RESULTS: There were no statistically significant differences in the clinical characteristics between the two groups. In terms of the duration of AVF patency after the first rescue therapy, group A showed a longer AVF patency duration than group B (24.5+/-21.9 months versus 17.7+/-13.6 months), but there was no statistically significant difference (p=0.310). In terms of the annual frequency of AVF occlusion after the rescue therapy of group A was lower than that of group B (0.59 versus 0.71), but there was no statistically significant difference (p=0.540). The AVF patency rates at 1, 2, 3, and 5 years after the first rescue therapy in group A were 52.6%, 31.5%, 21.0%, and 15.7%, respectively, and those in group B, they were 32.1%, 25.0%, 17.8%, and 7.14%, respectively. There was no statistically significant difference (p=0.402). CONCLUSION: Graft repair revealed comparable results. Although there was no statistically significant difference, the patent duration and annual frequency of AVF occlusion of group A were better than those of group B. Therefore, graft repair is considered as a safe and useful procedure for maintaining graft AVF.

Delayed massive hemothorax requiring surgery is relatively uncommon and can potentially be life-threatening. Here, we aimed to describe the nature and cause of delayed massive hemothorax requiring immediate surgery. Over 5 years, 1,278 consecutive patients were admitted after blunt trauma. Delayed hemothorax is defined as presenting with a follow-up chest radiograph and computed tomography showing blunting or effusion. A massive hemothorax is defined as blood drainage >1,500 mL after closed thoracostomy and continuous bleeding at 200 mL/hr for at least four hours. Five patients were identified all requiring emergency surgery. Delayed massive hemothorax presented 63.6±21.3 hours after blunt chest trauma. All patients had superficial diaphragmatic lacerations caused by the sharp edge of a broken rib. The mean preoperative chest tube drainage was 3,126±463 mL. We emphasize the high-risk of massive hemothorax in patients who have a broken rib with sharp edges.

Background: As the population of patients with end-stage renal disease has grown older, the proportion of patients with poorly preserved vasculature has concomitantly increased. Thus, arteriovenous grafts (AVG) have been used more frequently to access blood vessels for hemodialysis. Despite this increasing demand, studies of AVG are limited. In this study, we examined the surgical outcomes of upper-limb AVG creation. Methods: Among the arteriovenous fistula formation procedures performed between January 2014 and March 2019 at Dankook University Hospital, 42 cases involved AVG creation. We compared patients in whom the axillary vein was used (group A; brachioaxillary AVG [B-Ax AVG]; n=20) with those in whom upper limb veins were used (group B; brachiobasilic AVG or brachioantecubital AVG; n=22). Results: The 1-year primary patency rate was higher in group A than in group B (57.9% vs. 41.7%; p=0.262). The incidence of postoperative complications was not significantly different between groups. Conclusion AVG using the axillary vein showed no major differences in safety or functionality compared to AVG using other veins. Therefore, accounting for age, underlying disease, and expected patient lifespan, B-Ax AVG can be considered an acceptable surgical method.

The development of colorectai cancer following pelvic irradiation has been a much less common event. A 58-years-old woman presented with tenesmus for 5 months. She had a stage IIb, carcinoma of the cervix for which she underwent radiation therapy in 27 years before. Colonscopic findings revealed polypoid mass and irregular ulceration on the rectum and proctitis associated with stricture that was compatible with her previous history of radiation. Histoyathological examination of the polypectomy specimen disclosed adenocarcinoma. So we reported a case of radiation induced carcinoma of reotum which might be the first case in Korean literature. It therefore, behooves the clinician who follows patients whose carcinoma of the cervix or corpus uteri has been cured by radiation therapy to be vigilant for the subsequent development of colon and rectal cancer.

Pulmonary contusion complicated with endobronchial hemorrhage is potentially life-threatening, particularly in patients with tracheobronchial tree disruption and severe airway bleeding after blunt trauma, and pose a high mortality risk. In such cases, extracorporeal membrane oxygenation (ECMO) can be used as a salvage treatment modality. However, the use of ECMO for moribund trauma patients with respiratory failure may be limited for several reasons, such as intractable bleeding. In this case report, we describe a patient with severe bilateral pulmonary contusions with tracheobronchial tree disruption that was successfully treated using heparin-free venovenous ECMO.
