We describe surgical and adjuvant therapeutic management of a right ventricular (RV) sarcoma and pulmonary artery occlusion. Echocardiographic evaluation of a 39-year-old man with exertional dyspnea revealed a tumor mass in the right ventricle, pulmonary trunk, and bilateral pulmonary arteries. The tumor was resected with concomitant pulmonary valvotomy, but the resection was incomplete. The RV outflow was reconstructed with an allograft patch, and a stentless valve was implanted for pulmonary valvular function. The pulmonary trunk and arteries were enlarged with allograft patches. The tumor was undifferentiated sarcoma and caused postoperative pulmonary artery restenosis. Radiotherapy improved pulmonary perfusion (reduction of RV pressure), but the patient died of brain metastasis. Undifferentiated cardiac sarcomas associated with pulmonary hypoperfusion should be resected even if incompletely, and radiation therapy could alleviate reduced pulmonary perfusion.
我们描述了一例右心室(RV)肉瘤合并肺动脉闭塞的手术及辅助治疗管理。一名39岁劳力性呼吸困难男性的超声心动图评估显示右心室、肺动脉主干及双侧肺动脉有肿瘤团块。肿瘤在肺动脉瓣切开术的同时被切除,但切除不完全。用同种异体补片重建右心室流出道,并植入无支架瓣膜以恢复肺动脉瓣功能。用同种异体补片扩大肺动脉主干和动脉。肿瘤为未分化肉瘤,导致术后肺动脉再狭窄。放射治疗改善了肺灌注(右心室压力降低),但患者死于脑转移。即使不完全切除,与肺灌注不足相关的未分化心脏肉瘤也应切除,放射治疗可缓解肺灌注减少。
