ObjectiveTo summarize the clinical experience of aortic valve replacement surgery with minimally invasive procedure. MethodsWe retrospectively analyzed the clinical data of 72 patients underwent isolated aortic valve replacement in our hospital between January 2011 and August 2013. The patients undergoing minimally invasive procedure were as a minimally invasive group(30 patients with 18 males and 12 females at age of 60.2±13.4 years). The patients undergoings conventional procedure were as a control group(42 patients with 27 males and 15 females at age of 61.3±14.5 years). The outcomes of the two groups were compared. ResultsThere was no death and severe complication in both groups. Postoperative echocardiography showed no paravalvular leakage, no valve dysfunction in both groups. There were no significant statistically differences between the two groups in cardiopulmonary bypass time, aortic crossclamping time, ventilation time, postoperative left ventricle ejection fraction, the length of ICU stay and hospital stay (P>0.05). Blood transfusion ratio, blood transfusion volume and blood loss volume were lower in the minimally invasive group than those in the control group (P<0.05). The length of incision, chest closure time, operative duration were shorter in the minimally invasive group than those in the control group (P<0.05). ConclusionUpper median sternotomy is a safe and feasible procedure for minimally invasive aortic valve replacement surgery. Compared with conventional aortic valve replacement, its advantages include less surgical trauma, stable sternum, rapid recovery, less blood loss and blood transfusion, and cosmetic outcomes.
目的 探讨胸部正中小切口在婴幼儿先天性心脏病手术治疗中的可行性及效果。 方法 将我院 2016 年 5 月至 2016 年 10 月 170 例行手术治疗的常见先天性心脏病婴幼儿患者分为两组：常规组，85 例，男42例、女43例，年龄（6.9±2.1）个月，采用常规胸部正中切口；小切口组，85 例采用胸部正中小切口，男43例、女42例，年龄（6.4±1.8）个月。小切口手术切口于平第 3 肋间切开，止于剑突起始处上 0.5 cm，刚好放入小胸骨撑开器为好。 结果 两组患儿体外循环时间差异无统计学意义（P>0.05）。小切口组手术时间略长（P<0.05）。两组预后没有差别，但是小切口组伤口长度显著缩短[（7.8±0.8） cmvs. （4.0±0.5）cm，P<0.05]。 结论 正中小切口基本具有胸骨正中切口的优点，可显露心脏各部位，满足绝大部分心脏探查和手术操作需要，必要时仍可向上延长切口使心内操作不受限制等优点，故认为正中小切口在婴幼儿心脏手术中具有良好的安全性和美观性。
