摘要:
【摘要】 目的 验证一种建立实验犬经皮左心耳封堵途径方法的安全性及可行性。方法 12只实验犬房间隔穿刺后在不同体位左房造影后测量左心耳颈部直径,沿导丝送入输送封堵器的鞘管至左房中部,沿鞘管送入猪尾导管至左心耳内,沿猪尾导管推送输送长鞘进入左心耳内,退出猪尾导管经长鞘管造影观察鞘管在左心耳内的位置。术后1 h行心电图及经胸超声检查,即刻处死5只实验犬,取心脏观察房间隔穿刺位置、左房及左心耳内损伤情况。其余犬术后1 h及2周经胸超声心动图检查,随访1个月。结果 术中1只犬因心脏压塞死亡。8只犬在RAO30° + CRA20°造影可以清楚显示左心耳形态,3只在RAO30°,1只在RAO30° + CAU20°清楚显示左心耳形态,测量左心耳颈部直径为 (13.6 ± 5.2)mm,输送长鞘管均成功送入左心耳远端,无气栓、血栓、心脏压塞,2只穿刺点血肿,经加压包扎血肿吸收。术后即刻处死犬取心脏观察心包腔内未见血性液体,1只犬左房后壁轻度血肿, 2只左心耳上缘内膜轻度损伤可见血肿,手术操作时间(58 ± 12)min,透视时间(10.1 ± 2.5)min。其余犬术后及2周经胸超声随访无心包积液。随访1个月无猝死、卒中、感染。结论 应用本方法可安全有效的建立输送左心耳封堵器至左心耳内的途径。
