Abstract
BACKGROUND: Autosomal dominant hyper-IgE syndrome (AD-HIES) is a rare genetic syndrome that alters typical post-operative wound healing. AD-HIES patients are prone to develop persistent air leaks (PALs) due to bronchopleural fistulas. This report is unique in that it describes a novel approach to managing PALs in this complex population. CASE DESCRIPTION: Two patients with AD-HIES were identified in the setting of a PAL. The first patient was a 31-year-old male with recurrent pneumonia, who developed a large hydropneumothorax following re-presentation with fever and cough. A chest tube was inserted, which required continuous suction in the setting of what developed into a PAL. Subsequently, an endobronchial valve (EBV) was deployed to successfully manage the PAL. The second patient was a 25-year-old male, who developed a post-operative large volume air leak following a complicated surgical resection of a giant pneumatocele. Several attempts of placing multiple EBVs were required to finally address the PAL. In both cases, EBVs were successfully employed to manage and eventually resolve symptoms caused by PAL. CONCLUSIONS: Our experience suggests that EBVs are successful in treating PAL in the setting of AD-HIES, which often manifests as highly complex scenarios. Hence, EBVs represent a valuable addition to the therapeutic armamentarium against recalcitrant PAL. EBVs were well-tolerated in patients afflicted by AD-HIES, with no progressive infections noted. Both patients ultimately were able to resolve their PAL following placement of the EBV.
