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.

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.

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.

OBJECTIVE: The purpose of this study was to compare the results of different agents for bronchial artery embolization of hemoptysis. MATERIALS AND METHODS: From March 1992 to December 2006, a bronchial artery embolization was performed on 430 patients with hemoptysis. The patients were divided into three groups. Group 1 included 74 patients treated with a gelfoam particle (1x1x1 mm), while group 2 comprised of 205 patients treated with polyvinyl alcohol (PVA) at 355-500 micrometer, and group 3 included 151 patients treated with PVA at 500-710 micrometer. We categorized the results as technical and clinical successes, and also included the mid-term results. Retrospectively, the technical success was compared immediately after the procedure. The clinical success and mid-term results (percentage of patients who were free of hemoptysis) were compared at 1 and 12 months after the procedure, respectively. RESULTS: Neither the technical successes (group 1; 85%, 2; 85%, 3; 90%) nor the clinical successes (group 1; 72%, 2; 74%, 3; 71%) showed a significant difference among the 3 groups (p > 0.05). However, the mid-term results (group 1; 45%, 2; 63%, 3; 62%) and mid-term results excluding the recurrence from collateral vessels in each of the groups (group 1; 1 patient, 2; 4 patients, 3; 2 patients) showed that group 1 was lower than the other two groups (p < 0.05). No significant difference was discovered for the mid-term results between groups 2 and 3. Moreover, the same results not including incidences of recurrence from collateral vessels also showed no statistical significance between the two groups (p > 0.05). CONCLUSION: Polyvinyl alcohol appears to be the more optimal modality compared to gelfoam particle for bronchial artery embolization in order to improve the mid-term results. The material size of PVA needs to be selected to match with the vascular diameter.

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.

Glomerulonephritis and pulmonary hemorrhage are features of Goodpasture's syndrome. Goodpasture's syndrome accompanied with central nervous system (CNS) vasculitis is extremely rare. Herein, we report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues.
