Since the advent of endovascular techniques for repair of descending thoracic aortic aneurysms (DTAAs), there has been a relative paucity of current data for open repairs. The purpose of this study was to assess the operative and long-term outcomes in a contemporary series of open repairs of DTAAs.
We conducted a retrospective review of 68 patients (63±14.5 years) who underwent DTAA repairs between January 1999 and December 2010. Forty-two patients (62%) were male, 16 (24%) had chronic obstructive pulmonary disease, 7 (10%) required dialysis preoperatively, 11 (16%) had contained rupture, 25 (37%) had previous cardioaortic operations, and 10 (15%) had previous aortic arch replacement (stage 1 elephant trunk). The entire descending thoracic aorta was replaced in 34 patients (50%). Cardiopulmonary bypass was used in 64 patients (94%) and deep hypothermic arrest in 22 (32%).
In-hospital mortality was 3% (2 patients). There was no immediate paraplegia. Delayed paraplegia developed in 1 patient (1.5%). Postoperative stroke occurred in 3 patients (4.4%), and 20 (29%) required prolonged ventilatory support (intubation≥48 hours). New-onset renal insufficiency (creatinine≥2.5 mg/dL) developed postoperatively in 6 patients (9%), and 1 (1.5%) required temporary dialysis. The median follow-up time was 5.8±3.8 years. Sixteen of the 66 operative survivors (24.2%) died during follow-up. Probability of survival was 82%±0.05% at 5 years and 67%±0.07% at 10 years. Reintervention was necessary in 4 patients (6%). Freedom from reintervention was 98%±0.02% at 5 years and 89%±0.06% at 10 years. The univariable predictor of long-term death was postoperative reintubation (p<0.05).
In the era of endovascular repair of DTAAs, operative death and morbidity outcomes for open repairs are observed to be low. In addition to good long-term survival rates, open repairs are durable, as evidenced by low reintervention rates.
自从腔内技术用于修复降主动脉夹层瘤（DTAAs）以来，目前有关开放修复的最新数据相对较少。本研究旨在评估一组当代 DTAAs 开放修复的手术和长期结果。
我们回顾性分析了 1999 年 1 月至 2010 年 12 月期间接受 Dtaa 修复的 68 例患者（63±14.5 岁）。42 例（62%）为男性，16 例（24%）患有慢性阻塞性肺疾病，7 例（10%）术前需要透析，11 例（16%）为包裹性破裂，25 例（37%）有既往心主动脉手术史，10 例（15%）有既往主动脉弓置换术（一期象鼻手术）。34 例（50%）患者行全降主动脉置换。64 例（94%）患者采用体外循环，22 例（32%）采用深低温停循环。
院内死亡率为 3%（2 例）。无即刻截瘫。1 例（1.5%）发生迟发性截瘫。术后发生脑卒中 3 例（4.4%），20 例（29%）需要长时间机械通气（插管>48 小时）。6 例（9%）术后新发肾功能不全（肌酐≥2.5mg/dL），1 例（1.5%）需要临时透析。中位随访时间为 5.8±3.8 年。66 例手术存活者中，16 例（24.2%）在随访期间死亡。5 年生存率为 82%±0.05%，10 年生存率为 67%±0.07%。4 例（6%）需要再次干预。5 年无再干预率为 98%±0.02%，10 年无再干预率为 89%±0.06%。单变量预测长期死亡的因素是术后重新插管（p<0.05）。
在腔内修复 DTAAs 的时代，开放修复的手术死亡率和发病率均较低。除了良好的长期生存率外，开放修复的耐久性也很好，再干预率较低。
