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.

3.Comparative Study for the Efficacy of Small Bore Catheter in the Patients with Iatrogenic Pneumothorax.
The Korean Journal of Thoracic and Cardiovascular Surgery 2011;44(6):418-422
BACKGROUND: It has recently become most general to use the small bore catheter to perform closed thoracostomy in treating iatrogenic pneumothorax. This study was performed for analysis of the efficacy of treatment methods by using small bore catheter such as 7 F (French) central venous catheter, 10 F trocar catheter, 12 F pigtail catheter and for analysis of the appropriateness of each procedure. MATERIALS AND METHODS: From March 2007 to February 2010, Retrospective review of 105 patients with iatrogenic pneumothorax, who underwent closed thoracostomy by using small bore catheter, was performed. We analyzed the total success rate for all procedures as well as the individual success rate for each procedure, and analyzed the cause of failure, additional treatment method for failure, influential factors of treatment outcome, and complications. RESULTS: The most common causes of iatrogenic pneumothorax were presented as percutaneous needle aspiration(PCNA) in 48 cases (45.7%), and central venous catheterization in 26 cases (24.8%). The mean interval to thoracostomy after the procedure was measured as 5.2 hours (1~34 hours). Total success rate of thoracostomy was 78.1%. The success rate was not significantly difference by tube type, with 7 F central venous catheter as 80%, 10 F trocar catheter as 81.6%, and 12 F pigtail catheter as 71%. Twenty one out of 23 patients that had failed with small bore catheter treatment added large bore conventional thoracostomy, and another 2 patients received surgery. The causes for treatment failure were presented as continuous air leakage in 12 cases (52.2%) and tube malfunction in 7 cases (30%). The causes for failure did not present significant differences by tube type. Statistically significant factors affecting treatment performance were not discovered. CONCLUSION: Closed thoracostomy with small bore catheter proved to be effective for iatrogenic pneumothorax. The success rate was not difference for each type. However, it is important to select the appropriate catheter by considering the patient status, pneumothorax aspect, and medical personnel in the cardiothoracic surgery department of the relevant hospital.

BACKGROUND: Descending necrotizing mediastinitis (DNM) is a serious disease originating in odontogenic or oropharyngeal infection with high mortality despite adequate antibiotics and aggressive surgery. We analyzed results of treatment for DNM. MATERIAL AND METHOD: We studied 8 cases diagnosed as DNM from 1998 to 2007. All patients received emergent surgical drainage and debridement with broad spectrum antibiotics just after diagnosis. Antibiotics were changed after bacterial susceptibility testing. The surgical approach included 2 cases of cervicotomy, 6 cases of cervicotomy, and a thoracotomy. RESULT: The interval between symptom onset and hospitalization was 4.6+/-1.8 days (1~9 day). DNM originated in 4 cases of odontogenic infection (50%), 2 cases of oropharyngeal infection (25%), and 2 cases of unknown origin (25%). Causative organisms were found in 6 cases; Streptococcus in 4 cases, Staphylococcus in 1 case, and Klebsiella in 1 case. The Endo DNM classification was type I (2 cases), IIA (3 cases), and IIB (3 cases). The incidence of thoracotomy was 75%. The surgical mortality rate was 25% (2/8). The cause of death was multiple organ failure caused by septic shock. All mortality cases received only cervicotomy and aggravated infections after initial drainage. CONCLUSION: Early diagnosis, immediate surgical drainage, and adequate antibiotics, including covered anaerobes, are required. Thoracotomy should be performed with cervicotomy even for localized DNM.

BACKGROUND: Recently, percutaneous cardiopulmonary support (PCPS) has been widely used to rescue patients in cardiogenic shock or cardiac arrest. However, patients with cardiopulmonary bypass (CPB) weaning failure during open heart surgery still have very poor outcomes after PCPS. We investigated clinical results and prognostic factors for patients who underwent PCPS during open heart surgery. MATERIAL AND METHOD: From January 2005 to December 2008, 10 patients with CPB weaning failure during open heart surgery underwent PCPS using the CAPIOX emergency bypass system (EBS(R), Terumo Inc, Tokyo, Japan). We retrospectively reviewed the medical records of those 10 patients. RESULT: The average age of the patients was 60.2+/-16.5 years (range, 19~77 years). The mean supporting time was 48.7+/-64.7 hours (range, 4~210 hours). Of the 10 patients, 6 (60%) were successfully weaned from the PCPS While 5 (50%) were able to be discharged from the hospital. Complications were noted in 5 patients (50%). In univariate analysis, long aortic cross clamp time during surgery, mediastinal bleeding during PCPS and high level of Troponin-I before PCPS were significant risk factors. All of the discharged patients are still surviving 34+/-8.6 months (range, 23~48 months) post-operatively. CONCLUSION: The use of PCPS for CPB weaning failure during open heart surgery can improve the prognosis. More experience and additional clinical studies are necessary to improve survival and decrease complications.

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.

A 59-year old female patient was admitted due to massive hemoptysis. 6-months previously, we performed ascending aorta graft interposition for terating Debakey type 1 acute aortic dissection. Chest CT scan showed the fistula between the descending thoracic aorta and the left lower lobe. We performed descending thoracic aorta graft interposition under cardiopulmonary bypass. She recovered well without any postoperative problems. Distal aorto-bronchial fistula after a previous aortic operation is very rare. We report here the good results of treating aorto-bronchial fistula because we recognized this lesion early and performed an early operation.

A 40 year-old male patient admitted for dyspnea and edema of the lower extremities. A pulsatile abdominal mass with a bruit was palpable in the right lower quadrant. Four months previously, he had underwent left partial laminectomy (L4~5) and discectomy at the L4 level due to disc protrusion. Computed tomography showed an ilio-iliac AV fistula with pseudoaneurysm at the L5 level. Because massive bleeding occurred when the aneurysm was entered, we closed the aneurysm and performed resection and suture of the aorta and both iliac arteries very near the aneurysm. After exclusion of the arterial side, we performed reduction angioplasty at the aneurysm and aorto-biiliac reconstruction with an artificial graft. Twenty-four months after operation, he is doing well and hasn't had any complications on the follow-up.

Systemic infection with Aspergillus is an opportunistic disease that affects mainly immunocompromised hosts, and is associated with a high mortality rate. It typically occurs in patients with several predisposing factors, but Aspergillus endocarditis of native valves is rare and experience in diagnosis and treatment is limited. We report a case of native valve endocarditis caused by Aspergillus. A 35-yr-old male patient who underwent pericardiocentesis four months previously for pericardial effusion of unknown etiology presented with right leg pain and absence of the right femoral artery pulse. Cardiac echocardiography revealed severe mitral insufficiency with large mobile vegetations, and computed tomographic angiography showed embolic occlusion of both common iliac arteries. We performed mitral valve replacement and thromoembolectomy, and Aspergillus was identified as the vegetation. We started intravenous amphotericin B and oral itraconazole, but systemic complications developed including superior mesenteric artery aneurysm and gastrointestinal bleeding. After aggressive management, the patient was discharged 78 days post surgery on oral itraconazole. He was well at 12 months post discharge but died in a traffic accident 13 months after discharge.

Malperfusion of a major organ with aortic dissection has various clinical features according to the involved aortic branch. The morbidity and mortality rate can increase without suspicion especially during the intraoperative and postoperative period. Surgical outcomes and prognosis are influenced by early detection and active treatment, and expeditious diagnostic and therapeutic measures are mandatory for successful treatment. The authors report four successful cases of acute aortic dissection with malperfusion of various organs, such as the brain, kidney, and the lower extremities.
