一吃火鍋就手腳無力,這是怎么回事?

一吃火鍋就手腳無力,這是怎么回事?

6歲的明明是四川人,愛吃火鍋,可最近只要一吃火鍋,他就右腿發軟,吃完歇會,腿又好了。本來沒當回事,但最近連筷子都拿不穩了。到醫院一查,報告單上寫著“煙霧病”,這到底是怎么回事?

煙霧病,又稱自發性顱底動脈環閉塞癥,是由于頸內動脈及其分支的進行性狹窄閉塞,導致顱底出現代償性異常血管網。

簡單來說,大腦里的大血管越來越細,自身為了代償這種變化會在不好的血管周圍長出很多小血管。沒了好血管,大腦如同沒了水的莊稼,會逐漸枯萎。因為代償的血管看似云霧繚繞,就此取名“煙霧病”。

煙霧病的病因尚不明確,可能與遺傳相關,一些存在血液血管異常的疾病如血液病、血管炎、自身免疫疾病、發育障礙、心腦血管疾病、代謝疾病等,都有可能是煙霧病的病因。

得了煙霧病主要有以下表現:

■缺血性腦卒中和短暫性腦缺血發作

反復突然的一側肢體無力、活動障礙、言語不清、不能說話、一過性暈厥、看不見或看不清事物等。

對兒童而言,大腦前、中動脈血管區域的癥狀性缺血發作通常由運動、哭鬧、咳嗽、用力、發熱或過度通氣引起,像明明一吃火鍋就肢體無力,這其實是一種短暫性腦缺血的發作形式。

■腦內、腦室內和蛛網膜下腔出血

與兒童相比,腦出血更多見于成人,多伴有動脈瘤。

■其他

癲癇發作、頭痛、肌張力障礙、舞蹈病或運動障礙等,但較少見。

■無癥狀

煙霧病是一種進行性疾病,主要有兩個發作高峰,主高峰在5歲-9歲,另一高峰在35歲-39歲。在不發作的時候,患者可能無明顯癥狀。

目前,煙霧病首選手術治療,其目的是從附近好的血管調血來滋養缺血的壞大腦。

對于缺血型為主的兒童煙霧病,血管重建術可以改善腦血流、減輕缺血性損傷的程度和發作頻率、降低腦梗死的風險、改善術后的生活質量和腦功能。直接血管重建術一般將顳淺動脈與大腦皮質血管吻合,間接血管重建術利用頭皮、顳肌、硬腦膜等與大腦皮質血管融合,隨訪3-4個月,術后幾乎都能形成融合血管。

煙霧病可以不治嗎?肯定不行!煙霧病的自然病程往往是進展性的,血管病變通常會隨著廣泛的顱內大動脈閉塞及側支循環形成而加重。由于反復的缺血性腦卒中或出血,患者常會出現認知功能及神經系統功能減退,年齡較小的患兒病情進展更快速、腦梗發生率高且腦梗后恢復更差。
