赤外光観察対応胸腔鏡を用いて切除範囲を縮小しえた肺葉内分画症

The Successful Reduction of Resected Lung Volume for Intralobar Pulmonary Sequestration with Infrared Thoracoscope

肺内分画症は希少な先天性肺疾患である．分画肺は感染源になることがあり，治療方法としては手術が第一選択となるが，境界が不明瞭なため肺葉切除や区域切除で正常肺を含めて切除することも多い．

A 59-year-old male patient was referred to our hospital for further examinations and treatment due to an abnormal shadow detected in his left lower lung lobe on computed tomography. The patient was diagnosed with intralobar pulmonary sequestration and scheduled for an operation. During the surgery, after resection of the aberrant artery, indocyanine green was intravenously injected, and the border between normal lung and sequestrated lung was clearly identified by an infrared thoracoscope. Subsequently, wedge resection was performed, and the patient was discharged on postoperative day 5. Spirometry performed 6 months after the surgery indicated that the patient’s lung function was well-preserved compared to the preoperative status.
