Anastomotic Airway Complications after Lung Transplantation

PURPOSE: Anastomotic airway complications are a major cause of morbidity and mortality after lung transplantation (LTx). In this study, the authors identified types and clinical outcomes of airway complications after LTx. MATERIALS AND METHODS: All bronchial anastomotic complications were analyzed in a total of 94 LTx cases involving 90 recipients who underwent surgery between July 2006 and May 2014. Fifteen LTx cases (14 recipients) with incomplete medical records for fiberoptic bronchoscopy (FBS) and three cases underwent heart-lung transplantation (HLT) were excluded. Postoperative FBS at 24-48 hours, 1, 3, 6, and 12 months, and then yearly after the transplantation were performed. RESULTS: A total of 76 LTx cases (75 recipients) were analyzed. The mean age of the recipients was 49.55 years (range, 18-71 years), and 38 (49.4%) were male. Twenty-one out of 76 cases (27.6%) experienced early anastomotic complications, and 12 (15.8%) presented late anastomotic complications. The early anastomotic airway complications presented in various forms: stenosis, 1 case; narrowing, 1; necrosis & dehiscence, 3; fistula, 4; granulation, 10; and infection, 2. Late complications almost entirely presented in the form of bronchial stenosis; five recipients showed stenosis at the anastomosis site, and one of them showed improvement after ballooning. Five others were found to have stenosis at the bronchus intermedius, distal to the anastomosis site. Three of these patients showed improvement after ballooning or bronchoplasty. CONCLUSION: By serial surveillance via FBS after LTx, we detected anastomotic airway complications in 42.9% of cases, which were successfully managed with improved clinical outcomes.

A Rare Case of Primary Thymic Adenocarcinoma Mimicking Small Cell Lung Cancer / 결핵및호흡기질환

Primary thymic adenocarcinoma is a very rare malignancy of the anterior mediastinum with no standardized treatment. A 36-year-old male patient presented with hoarseness over the past 3 months. A chest computed tomography (CT) scan showed an infiltrative mass to the proximal vessels and aortic arch in left upper mediastinum (4.1x3.1x5.4 cm). Brain magnetic resonance imaging (MRI) showed focal lesions, suggesting metastasis in the left frontal lobe. A thoracoscopic biopsy of the mediastinal mass confirmed a primary thymic adenocarcinoma forming a glandular structure with atypia of tumor cells. The patient received four cycles of systemic chemotherapy, consisting of etoposide and cisplatin, with concurrent radiotherapy (6,000 cGy/30 fractions) to the mediastinal lesion and the metastatic brain lesion (4,200 cGy/12 fractions). A follow-up chest CT scan and brain MRI showed a decrease in the size of the left upper mediastinal mass and brain lesion. We report a rare case of the primary thymic adenocarcinoma with a literature review.

Late Respiratory Infection after Lung Transplantation / 결핵및호흡기질환

BACKGROUND: Aiming to improve outcome of lung transplantation (LTx) patients, we reviewed risk factors and treatment practices for the LTx recipients who experienced respiratory infection in the late post-LTx period (>1 month after LTx). METHODS: We analyzed the clinical data of 48 recipients and donors from 61 LTx, who experienced late respiratory infections. Late respiratory infections were classified according to the etiology, time of occurrence, and frequency of donor-to-host transmission or colonization of the recipient prior to transplantation. RESULTS: During the period of observation, 42 episodes of respiratory infections occurred. The organisms most frequently involved were gram (-) bacteria: Acinetobacter baumannii (n=13, 31.0%), Pseudomonas aeruginosa (n=7, 16.7%), and Klebsiella pneumoniae (n=4, 10.0%). Among the 42 episodes recorded, 14 occurred in the late post-LTx period. These were bacterial (n=6, 42.9%), fungal (n=2, 14.3%), viral (n=4, 28.5%), and mycobacterial (n=2, 14.3%) infections. Of 6 bacterial infections, 2 were from multidrug-resistant (MDR) A. baumannii and one from each of MDR P. aeruginosa, extended spectrum beta-lactamase (+) K. pneumoniae, methicillin-resistant Staphylococcus aureus and Streptococcus pneumoniae. Infection-related death occurred in 6 of the 14 episodes (43%). CONCLUSION: Although the frequency of respiratory infection decreased sharply in the late post-LTx period, respiratory infection was still a major cause of mortality. Gram (-) MDR bacteria were the agents most commonly identified in these infections.

A Cerebral Air Embolism after CT-Guided Percutaneous Transthoracic Fine-Needle Aspiration Biopsy of the Lung / 대한내과학회지

Low-dose thoracic computed tomography (CT) for the early diagnosis of lung cancer detects many solitary pulmonary nodules. Fine needle aspiration biopsy (FNAB) is the diagnostic method used most commonly in the diagnosis of solitary pulmonary nodules. Cerebral air embolism is a rare, fatal complication of FNAB. Hyperbaric oxygenation therapy within 6 hours of the event ensures a good prognosis with cerebral air embolisms. We present a case of cerebral air embolism that occurred during CT-guided lung FNAB biopsy that was treated with hyperbaric oxygenation within 6 hours. The patient recovered completely from the neurological deficit and had a favorable long-term outcome.

A Case of Locally Advanced Well-Differentiated Fetal Adenocarcinoma of the Lung Treated with Concurrent Chemoradiation Therapy / 결핵및호흡기질환

Fetal adenocarcinoma is a rare adenocarcinoma subtype of pulmonary blastoma. A 48-year-old male patient is being referred to our hospital due to progressive dyspnea. A chest X-ray showed a lung mass of unknown origin that was obstructing the right main bronchus. After relieving the airway obstruction with stent insertion via bronchoscopy, a diagnosis of fetal adenocarcinoma is being confirmed through thoracoscopic biopsy. Due to the locally advanced state of the lung cancer, it seemed to be inoperable, and concurrent chemo-radiation therapy was being administered with docetaxel. The stent was removed after improvements in the airway obstruction followed by a lung mass shrinkage. Comparing to other contexts which describe fetal adenocarcinoma as lower grade malignancy with low-associated mortality, herein, we describe a case of locally-advanced fetal adenocarcinoma (T4N3M0). This is the first documented case being treated with concurrent chemoradiation therapy. The followed-up image studies represent a partial response and the patient is currently under further observations.

A Case of an Exoluminal Gastrointestinal Stromal Tumor That Was Confused with a Metastatic Lymph Node in Early Gastric Cancer / 대한소화기내시경학회지

Gastric adenocarcinoma may coexist with tumors of other histological types. The synchronous occurrence of gastric adenocarcinoma and gastrointestinal stromal tumor (GIST) has rarely been reported in the literature. It is still not known whether such an association represents an incidental coexistence or indicates a similar pathogenesis in the simultaneous development of tumors of different histological types. Here we report a case of an exoluminal GIST that was confused with a metastatic lymph node in early gastric cancer.

A Case of Holoprosencephaly / 대한산부인과학회잡지

Holoprosencephaly is a complex abnormality of the forebrain that is postulated to derive from a failure in the diverticulation of the embryonic prosencephalon. Early antenatal diagnosis of holoprosencephaly is important to find out its severity, to predict its prognosis and to determine proper treatment according to its prognosis and severity. With recent development of high resolution ultrasonography, it is possible to detect a fetus with holoprosencephaly at early antenatal period. We report a case of alobar holoprosencephaly, diagnosed antenatally with its sonographic and autopsy finding.

A Case of Uterine Rupture in the 18th Week of Pregnancy / 대한산부인과학회잡지

Spontaneous uterine rupture during the second trimester of pregnancy is a rare obstetric emergency. When a patient presents with acute abdominal pain and signs of hemorrhagic shock, a number of differential diagnoses must be considered. Early diagnosis and proper management is necessary to decreased the high maternal and fetal morbidity and mortality associated with rupture of uterus. We present a case of spontaneous rupture of the uterus in the 18th week of pregnancy with a brief review of literatures.

A Review of Prenatal Cytogenetic Analysis in 2942 Midtrimester Amniocentesis / 대한산부인과학회잡지

OBJECTIVES: To analyze 2942 cases of prenatal genetic amniocentesis with their cytogenetic results. METHODS: This study reviewed 2942 genetic amniocentesis results which were perfomed at Ilsin Christian Hospital from 1993 to 1999, as prenatal genetic diagnosis for the possibility of chromosomal abnormality of fetus. Age distribution, gestational weeks, indications of amniocentesis and cytogenetic results were the key factors for the analysis. RESULTS: Maternal ages were ranged from 20 to 45, mostly 25-39. Of indications of prenatal genetic amniocentesis, abnormal maternal serum marker was the most common(57.9%) and followed by advanced maternal age(29.3%). The frequency of abnormal karyotypes was 3.1%(90/2942). Down syndrome(trisomy 21) and inversion of chromosome were found at 0.8%(24/2942) and 1.0%(30/2942). The incidence of abnormal karyotype according to indication had statistical significance in family history and abnormal ultrasonographic findings.(p<0.001) CONCLUSIONS: Midtrimester genetic amniocentesis is an important diagnostic tool in prenatal genetic diagnosis. In addition to the maternal serum markers and maternal ages, complete family history takings and ultrasonograms should be considered in prenatal genetic counseling.
