OBJECTIVETo investigate the causes, clinical features, therapy and treatment outcomes of recurrent hemoptysis in children and to improve the skills of pediatricians in the etiological diagnosis and treatment of recurrent hemoptysis in children.

METHODSThe clinical, laboratory, and imaging data of 39 children with recurrent hemoptysis between January 1996 and February 2013 were collected to retrospectively analyze the age of onset, etiology, amount of hemoptysis, imaging changes, treatment methods, and follow-up outcomes.

RESULTSIn the 39 children, including idiopathic pulmonary hemosiderosis (16 cases, 41%), pulmonary vascular malformation (8 cases, 21%), pulmonary arteriovenous fistula (7 cases, 18%), bronchiectasis (3 cases, 8%), pulmonary tuberculosis (2 cases, 5%), pulmonary cystic fibrosis (2 cases, 5%), and lung tumor (1 case, 3%). The contrast-enhanced lung CT scans and pulmonary and bronchial arteriography revealed varying degrees of lung imaging changes in 35 cases. Of all cases, 51% were classified as degree I, 28% as degree II, and 21% as degree III. All children were treated according to the etiology, with the disease controlled. During 0.5-5 years of follow-up, 3 patients with idiopathic pulmonary hemosiderosis were lost to follow-up, and the other cases did not develop hemoptysis again.

CONCLUSIONSIdiopathic pulmonary hemosiderosis is the main cause of recurrent hemoptysis in children. Contrast-enhanced lung CT scans and pulmonary and bronchial arteriography are important methods for the etiological diagnosis of recurrent hemoptysis in children. Treatment methods should be selected according to the etiology.

Hemoptysis in patients with lung cancer is not uncommon and sometimes have dangerous consequences. Hemoptysis has been managed with various treatment options other than surgery and medicine, such as endobronchial tamponade, transcatheter arterial embolization and radiation therapy. However, these methods can sometimes be used only temporarily or are not suitable for a patient's condition. We present a case in which uncontrollable hemoptysis caused by central lung cancer was successfully treated by inserting a covered self-expanding bronchial stent. The patient could be extubated and was able to undergo further palliative therapy. No recurrent episodes of hemoptysis occurred for the following three months. As our case, airway stenting is a considerable option for the tamponade of a bleeding lesion that cannot be successfully managed with other treatment methods and could be used to preserve airway patency in a select group of patients.

Management of cryptogenic massive hemoptysis is difficult, and conservative treatment may be inadequate to stop the hemorrhage. Surgery is not a reasonable option because there is no underlying identifiable pathology. This study aimed to investigate the radiologic findings and bronchial artery embolization outcomes in cryptogenic hemoptysis, and to compare the results with non-cryptogenic hemoptysis. We evaluated 26 patients with cryptogenic hemoptysis and 152 patients with non-cryptogenic hemoptysis. A comparison of the bronchial artery abnormalities between the cryptogenic and non-cryptogenic hemoptysis groups showed that only extravasation was more statistically significant in the cryptogenic hemoptysis group than in the non-cryptogenic hemoptysis group, while the other bronchial artery abnormalities, such as bronchial artery dilatation, hypervascularity, and bronchial-to-pulmonary shunting, showed no significant difference between groups. Involvement of the non-bronchial systemic artery was significantly greater in the non-cryptogenic hemoptysis group than in the cryptogenic hemoptysis group. While 69.2% of patients with cryptogenic hemoptysis also had hypervascularity in the contralateral bronchial arteries and/or ipsilateral bronchial artery branches other than the bleeding lobar branches, this finding was not detected in non-cryptogenic hemoptysis. Embolization was performed on all patients using polyvinyl alcohol particles of 355-500 microm. Hemoptysis ceased in all patients immediately after embolization. While recurrence of hemoptysis showed no statistically significant difference between the cryptogenic and non-cryptogenic hemoptysis groups, it was mild in cryptogenic hemoptysis in contrast to mostly severe in non-cryptogenic hemoptysis. Transarterial embolization is a safe and effective technique to manage cryptogenic hemoptysis.

We report on three cases of longstanding pulmonary tuberculosis patients with coronary to bronchial artery fistula (CBF) who presented with recurrent massive hemoptysis. The first and second patients died because of decreased functional pulmonary volume plus massive hemoptysis and cannulation failure of CBF due to hypovolemic vasospasm, respectively. When recurrent hemoptysis occurs despite successful embolization treatment, CBF should be considered as a potential bleeding source. Moreover, a coronary angiography should be performed, especially in patients with longstanding cardiopulmonary disease such as pulmonary tuberculosis.

Malignant airway obstruction and hemoptysis are common in lung cancer patients. Recently, airway stent is commonly used to preserve airway in malignant airway obstruction. Hemoptysis can be managed through various methods including conservative treatment, endobronchial tamponade, bronchoscopic intervention, embolization and surgery. In our case studies, we sought to investigate the effectiveness of airway stents for re-opening the airway as well as tamponade effects in four patients with malignant airway obstruction and bleeding caused by tumors or lymph node invasions.

A bronchial artery embolization (BAE) is an important therapeutic method used to control acute and chronic hemoptysis. We report a case of multiple micro-infarcts involving both the kidneys and spleen, following a BAE with 500-700 micrometer crossed-linked tris-acryl microspheres (Embospheres) in a patient with bronchial artery pulmonary vein shunts. The superior penetration characteristics of the microspheres may have resulted in the greater tendency to cross the bronchial artery pulmonary vein shunts, which subsequently caused the systemic infarcts in our patient. We propose the use of larger sized microspheres (700-900 micrometer), which may aid in avoiding this complication.

BACKGROUND: Pulmonary aspergilloma usually results from the ingrowth of colonized Aspergillus from a damaged bronchial tree, a pulmonary cyst, or from the cavities of patients with underlying lung diseases. In the present study, we analyzed the clinical features, diagnostic methods, and managements of 36 patients with pulmonary aspergilloma. METHODS: Thirty-six patients were diagnosed as having pulmonary aspergilloma at Chung-Ang University Hospital between February 1988 and February 2000. Their medical records were reviewed retrospectively. RESULTS: The age of patients (median +/- SD) was 53.3 +/- 11.8 years, the male to female ratio was 2.36: 1, and the most frequent symptom was hemoptysis, which occurred in 24 patients (65%). The most common underlying disease was pulmonary tuberculosis (81%), and the upper lobes of both lungs were the most frequently involved sites. Nine patients received a chest CT in the prone position and seven of these showed a movable fungus ball. Eleven patients were positive for the precipitin antibody to A. fumigatus. Twenty patients underwent surgical resection, and post-operative complications were reported in seven cases. The post-operative mortality was 5.6% (2/36). CONCLUSION: Pulmonary aspergilloma usually develops in the patients with underlying lung diseases. Resectional lung surgery is considered the mainstay of therapy for pulmonary aspergilloma. However, this operation is associated with significant complications and death in some cases. Therefore, it is necessary to develop reasonable criteria for selection of candidates for such surgery.

A 60-year-old man presented with cough, sputum, and dyspnea. He had a history of acute myeloid leukemia and hematopoietic stem cell transplantation with chronic renal failure. Chest CT scans showed miliary nodules and patchy consolidations. Histological examination revealed numerous fibrin balls within the alveoli and thickening of the alveolar septum, both of which are typical pathological features of acute fibrinous and organizing pneumonia (AFOP). We report the first case of AFOP following allogeneic hematopoietic stem cell transplantation.
