肺癌手術時の胸腔内蒸留水洗浄により心電図ST上昇を認めた1例

ST Segment Elevation on Electrocardiogram （ECG） during Pleural Lavage with Distilled Water；Report of a Case

はじめに　肺癌手術において温蒸留水による胸腔内洗浄は腫瘍細胞の播種を防ぐなどの目的で行われている．しかしながら，その効果についてはさまざまな議論があり，副作用に関しても十分な検討がなされていないのが現状である．われわれは，術中温蒸留水による胸腔内洗浄時に一過性に心電図ST上昇を認めた1例を経験したので報告する．

Pleural lavage with distilled water is often employed in lung resection to eliminate malignant cells. Here we report a case of transient ST segment elevation on electrocardiogram （ECG） during pleural lavage with distilled water. A 73-year-old female was referred to our hospital because of an abnormal shadow on a chest roentogenogram. Chest computed tomography scan revealed a mass in left S4＋5 segment of left upper lobe. It was proved to be adenocarcinoma of the lung by transbronchial lung biopsy and she underwent left upper lobectomy. During pleural lavage with distilled water, ST segment was elevated on ECG. In this case, it was because that the pericardium was excised and the myocardium was exposed to distilled water during pleural lavage.
