1 臨床資料

患者,女,15歲,因父母發(fā)現(xiàn)其持物不穩(wěn)及不能完成跳繩動作而就診,追問患者偶發(fā)頭痛?查體:體形消瘦,眼球前凸,頸靜脈無怒張,兩側(cè)胸廓不對稱,漏斗胸(輕度),雙肺呼吸音清,未聞及干濕性啰音;心尖搏動范圍正常,心率80次/分,心臟相對濁音界正常,各瓣膜聽診區(qū)未聞及雜音?周圍血管無毛細(xì)血管搏動及水沖脈?腹部及神經(jīng)檢查陰性,雙下肢無水腫?蜘蛛指(雙手纖長),指征及腕征陽性,脊柱側(cè)彎,足弓過高,關(guān)節(jié)松弛,雙上肢肌力正常,右下肢肌力4級,左下肢肌力5級,各病理征陰性?血?尿常規(guī)及各項生化檢查未見異常;24h動態(tài)心電圖示偶發(fā)房性期前收縮,見圖1;心臟彩超示左心室心肌致密化不全,見圖2;肺部平片未見異常,脊柱正?側(cè)位X線片示脊椎側(cè)彎,見圖3;脊髓MRI示頸2至胸1硬膜囊擴(kuò)張,見圖4?診斷:馬方綜合征,左心室心肌致密化不全?

2 討 論

馬方綜合征是人類第15號常染色體長臂上FBN1基因缺陷所致的全身性結(jié)締組織遺傳病[1]?臨床主要以心血管?眼和骨骼肌肉系統(tǒng)受累為主,其中30.00%～60.00%的患者有血管系統(tǒng)異常?馬方綜合征患者心血管系統(tǒng)病變中主動脈根部擴(kuò)張占93.80%,主動脈瓣關(guān)閉不全占87.50%,主動脈夾層占46.90%,二尖瓣脫垂占12.50%,主動脈竇瘤占6.20%,肺動脈擴(kuò)張占3.10%,心包積液占12.50%,二葉主動脈瓣占6.20%,房間隔缺損占3.10%,主動脈縮窄占1.00%[2]?

心肌致密化不全是一種罕見的原發(fā)性心肌病?2006年美國心臟病協(xié)會(AHA)將心肌致密化不全歸為遺傳性心肌病,2008年歐洲心臟病協(xié)會(ESC)將其歸為未定型心肌病?心肌致密化不全的發(fā)病率為0.05%～0.24%[3],有家族聚集傾向,日本家族發(fā)病率為44.00%,中國為18.00%～40.00%[4-5]?有研究認(rèn)為心肌致密化不全與常染色體18q?11q?10q基因突變有關(guān)[6-8]?心肌致密化不全臨床癥狀出現(xiàn)的早晚及輕重與病變范圍有關(guān),以心力衰竭?心律失常?血栓栓塞為三大臨床表現(xiàn),患者心臟性猝死發(fā)生率高達(dá)13.00%～18.00%[9-11],室性快速性心動過速被認(rèn)為是一種最常見的致死原因,大多數(shù)心肌致密化不全患者在確診時已具有室性心律失常及心力衰竭癥狀,而本病多與生俱來,故而早期診斷將直接影響患者的生存率,早期診斷并早期應(yīng)用植入性心臟除顫器(ICD)對患者(尤其是有室性快速性心律失常患者)的預(yù)后均大有裨益[12-14]?以往研究未發(fā)現(xiàn)心肌致密化不全患者合并有典型馬方綜合征[15],而眾多關(guān)于馬方綜合征心臟病報道中,亦無心肌致密化不全記載[2],本例的發(fā)現(xiàn)無疑對二者互相參診具有重要意義?
