To evaluate the effects of a left ventricular assist device (LVAD) during the reperfusion period following acute coronary occlusion, sixteen mongrel dog hearts were subjected to 1 hour’s occlusion of the circumflex coronary artery and then reperfused for 6 hours. In seven control dogs (control group), the hearts were reperfused without any support. In nine LVAD dogs (LVAD group), however, the left ventricles were supported by the application of a pneumatic driven diaphragm-type pump for 5 hours and then reperfused for another hour without any device. Triphenyltetrazolium chloride was used to determine the extent of infarction. The results showed a significant reduction in the area of infarct (AI) as a percentage of the area at risk (AR) in the LVAD group compared with the control group, the AI/AR being 22.3 per cent for the control groupversus 4.8 per cent for the LVAD group (p<0.05). The cardiac output was also significantly higher in the LVAD group compared with the control group. The per cent systolic shortening in the ischemic region of the LVAD group showed a significantly better recovery, being 75.8 per cent for the LVAD groupversus 24.4 per cent for the control group (p<0.01). It was concluded that the application of a LVAD during reperfusion after 1 hour’s coronary occlusion results in a significant reduction of infarct size and provides improvement in both regional and global cardiac function.

症例は78歳の男性で, 右季肋部痛・背部痛を主訴に近医を受診し, 後腹膜腫瘍の診断で当科に紹介された. 血液検査ではLDHの上昇を認め, 腹部CT・MRIで右副腎に造影効果のあるφ15×15cm大の腫瘍を認め, 肝・右腎への浸潤も疑われた. 腹部血管造影では右下副腎動脈をfeeding-arteryとするtumor-stainを認めた. 以上より, 肝・右腎浸潤を伴う右副腎原発悪性腫瘍と診断し肝右葉・右腎と腫瘍を一塊に切除した. 摘出標本は1.3kg, 腫瘍は白色充実性・弾性硬腫瘤で肝右葉および右腎への直接浸潤を認めた. 病理組織では悪性リンパ腫 (diffuse mixed sized B-cell type) であった. 術後第29病日に退院. 自宅療養の後CHOP療法を4クール施行した. 現在, 術後2年を経過した現在も再発の兆候はなく経過観察中である. 副腎原発悪性リンパ腫に対しては早期発見・積極的治療が重要と考える.
