Management of long-term persistent air leakage developed after bullectomy for giant bullous lung disease associated with neurofibromatosis type 1

Persistent air leakage is a serious and sometimes fatal complication of bullous lung disease surgery. A 32-year-old man with lung involvement of neurofibromatosis type I underwent bullectomy for huge bullae and recurrent pneumothorax. Persistent postoperative air leakage developed and the lung was totally collapsed. The initial surgery failed, but a second trial employing a novel suture technique on half-absorbed polyglycolic acid (PGA) felt successfully resolved the massive air leakage. Pneumothorax did not recur and the patient remained stable without dyspnea. Thus, a suture technique employing half-absorbed PGA felt was an effective option for managing persistent air leakage.
