目的:探討磁共振血管造影(MRA)以及計算機斷層掃描血管成像(CTA)對地震擠壓傷下肢血管病變的臨床價值。方法:對5·12汶川大地震中我院收治的已確診為地震擠壓傷致雙下肢橫紋肌溶解癥3例患者進行雙下肢MRA檢查,并對嚴重擠壓傷及下肢毀損,并行截肢的另三名患者進行術(shù)后CTA檢查。對MRA圖象雙下肢動脈進行回顧性分析,總結(jié)MRA征象,同時總結(jié)截肢術(shù)后患者CTA表現(xiàn)及臨床價值,并評價二者檢查在擠壓傷所至橫紋肌溶解癥的臨床診治中的作用。結(jié)果:3例未行截肢患者MRA雙下肢主要動脈未見確切狹窄及閉塞征象,管腔內(nèi)未見充盈缺損影。3例已行截肢患者可見殘余肢體的明顯腫脹,雙側(cè)髂血管以及部分截斷肢體遠端血管內(nèi)見止血彈簧鋼圈影像,部分截斷肢體遠端動脈分支變細。截斷血管未見再通,周圍無滲血改變。結(jié)論:MRA、CTA能直觀顯示雙下肢動脈損傷及術(shù)后情況,在臨床應(yīng)用中各有優(yōu)勢和局限性。對二者的合理選擇能為臨床診治提供有利信息。
