目的 探討超聲引導(dǎo)下活體犬肝注射不同劑量的醋酸高滲氯化鈉液(acetic acid hypertonic saline solution,AHS)后行射頻消融(RFA),觀察犬肝一次性毀損體積的變化。
方法 使用LDRF-120S多極RFA系統(tǒng)聯(lián)合AHS對活體犬肝行RFA。健康成年雜種犬30只,隨機(jī)分為5組(n=6)。A組: 注射2 ml AHS后立即行RFA; B組: 注射2 ml AHS后延時(shí)5 min行RFA; C組: 注射4 ml AHS后立即行RFA; D組: 注射4 ml AHS后延時(shí)5 min行RFA; E組: 注射6 ml AHS后立即行RFA。
結(jié)果 5組間平均起始阻抗差異無統(tǒng)計(jì)學(xué)意義(P gt;0.05); 5組間平均消融時(shí)間差異有統(tǒng)計(jì)學(xué)意義(F=83.831,P<0.001),LSD-t檢驗(yàn)分析各組間兩兩比較差異有統(tǒng)計(jì)學(xué)意義(P<0.001),在觀察范圍內(nèi)E組平均消融時(shí)間最長; 5組間平均毀損直徑差異有統(tǒng)計(jì)學(xué)意義(F=53.488,P<0.001),在觀察范圍內(nèi)E組平均毀損直徑最大,LSD-t檢驗(yàn)分析除D與E組間差異無統(tǒng)計(jì)學(xué)意義(P gt;0.05)外,其余各組間兩兩比較差異有統(tǒng)計(jì)學(xué)意義(P<0.001); 網(wǎng)狀纖維染色顯示凝固壞死區(qū)及其鄰近的正常肝組織均可見血管內(nèi)血栓形成; E組在AHS注射過程中出現(xiàn)不同程度的外溢; A、B、C及D組14 d內(nèi)無動(dòng)物死亡,E組死亡4只。
結(jié)論 活體犬肝局部注射AHS 4 ml后延時(shí)5 min行RFA即可達(dá)到較理想的毀損體積。
