右心房黏液瘤合併肺栓塞──個案報告

Right Atrial Myxoma With Pulmonary Embolism

原發性心臟腫瘤是少見的(0.0017%~0.05%)，右心房黏液瘤更是相當罕見的原發性心臟腫瘤，而且要診斷腫瘤之期別相當困難，最常發生之致死性併發症是由腫瘤之碎片所導致之肺栓塞，因此早期的診斷是相當重要的。外科手術切除心房黏液瘤的術後結果是相當好的。在此，我們報導一位，68歲，女性病患，因呼吸困難和胸痛而到某區域醫院作檢查；經過詳細醫療檢查評估結果，病患被診斷為右心房黏液瘤合併肺栓塞，經緊急施行右心房黏液瘤切除及肺動脈栓塞切除術，病患術後追蹤，癒後狀況良好。

Primary cardiac tumors are rare with an autopsy incidence ranging from 0.0017~0.05%. Right atrial myxoma is one of the rarest of primary cardiac tumors and a tumor type that is difficult to diagnose. The most common fatal complication is pulmonary embolism from tumor fragments originating from the tumor mass. Thus early diagnosis of cardiac myxoma is important. The surgical excision of atriac myxoma would appear to elicit excellent short-term and long-term results. Here we report a 68 years old female who was admitted to regional hospital for investigation of chest pain and dyspnea, both of which arose suddenly six days prior to her admission to our hospital. Subsequent to a comprehensive medical investigation, a right atrial myxoma with pulmonary embolism was diagnosed for this patient. Emergency surgery including right atrial myxoma excision and pulmonary embolectomy was performed, with subsequent excellent results for this patient.
