Radiological Findings and Outcomes of Bronchial Artery Embolization in Cryptogenic Hemoptysis

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 noncryptogenic 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 μm. 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

Transcatheter Closure of a Residual Patent Ductus Arteriosus After Surgical Ligation in Children
Osman Baspinar,Metin Kilinc,Mehmet Kervancioglu,Ahmet Irdem 대한심장학회 2011 Korean Circulation Journal Vol.41 No.11
Background and Objectives: To assess the safety and efficacy of transcatheter closure of residual ductal flow after initial surgical ligation of the arterial duct. Subjects and Methods: Between June 2005 and December 2009, transcatheter occlusion of residual postsurgical ductus arteriosus was performed in six children. Results: The mean patient age was 10±5.5 years; mean post-procedural time since the initial surgical closure was 6.3±4.5 years. The mean diameter of the patent ductus arteriosus on angiography was 1.3±0.5 mm (range, 0.8 to 2.4 mm). Three different types of coils were used successfully without any complications. Conclusion: Transcatheter occlusion of residual postsurgical arterial duct is a safe and successful procedure. However, attention should be paid due to the distorting shape of the arterial duct.
