Early- and medium-term results after aortic arch replacement with frozen elephant trunk techniques-a single center study.

摘要: Background: The treatment of patients with extensive thoracic aortic disease involving the arch and descending thoracic/thoracoabdominal aorta is often performed using frozen elephant trunk technique (FET). We retrospectively analyzed our results FET operation. Methods: A total 51 consecutive underwent surgery between January 2006 August 2013. For all patients, E-vita hybrid open stent-graft (Jotec, Hechingen, Germany) was used. had a mean age 64±13 years, 51.1% being female. Degenerative or atherosclerotic aneurysm indication for in 62.7% patients. Another 15.7% 13.7% suffered from acute Type A, B dissection, respectively. Results: in-hospital 30-day mortality 7.8%. Stroke occurred 11.8% (n=6), new-onset paraplegia 19.6% (n=10) core body temperature ≥28 ℃ during circulatory arrest, combination prolonged arrest time more than 45 minutes, an independent predictor permanent spinal cord injury [odds ratios (OR), 4.8; 95% confidence intervals (CI), 1.1-21; P=0.04]. estimated 1- 5-year survival (80.2±5.5)% (59.7±10.2)%, respectively, 3.4±0.4 years. freedom endovascular intervention 4.2±0.4 unadjusted repair (TEVAR) (84.9±5.9)% (69.2±11.2)%, Conclusions: procedure associated acceptable early medium term rate. This high incidence perioperative injury. In order to prevent above complication, deep hypothermia strongly recommended expected time.
