細径鉗子を併用し細径胸腔鏡下に摘出した胸壁海綿状血管腫

Thoracoscopic Surgery by Thin Thoracoscope with Fine Needlescopic Forceps for Cavernous Hemangioma in the Chest Wall

胸壁腫瘍に対する治療では外科的切除が第一選択であることが多い．しかし良性腫瘍の場合，特に若年者では手術の整容性を含めた低侵襲手術を考慮しなければならない．われわれは，若年女性に発生した胸壁海綿状血管腫に対して，細径鉗子と細径胸腔鏡を用いて切除した症例を報告する．

A 27-year-old women was referred to our hospital because of abnormal subpleural nodule in her right thoracic cavity. Chest computed tomography demonstrated an 11 mm nodule with smooth and clear boundary adjacent to the right first rib. Chest magnetic resonance imaging revealed an iso-intensity area on T1-weighted images, a high-intensity on T2-weighted images, and enhanced homogeneously on contrast-enhanced images. Tumor extirpation was performed using a 2.7 mm grasp fine needlescopic forceps, a 3 mm thoracoscope and a 5 mm vascular sealing device. The histological diagnosis was cavernous hemangioma. Thoracoscopic surgery using fine needlescopic forceps and thin thoracoscope is useful in considering esthetic purposes.
