Abstract:
Objective To evaluate whether long frozen elephant trunk (FET) increases the risk of spinal cord injury in patients with acute type A aortic dissection. Methods From 2018 to 2019, 172 patients with acute type A aortic dissection were treated in Guangdong Provincial People’s Hospital. They were divided into two groups according to the length of FET: patients treated with stents of 100 mm in length were enrolled into a short FET group, and those with stents of 150 mm in length into a long FET group. There were 124 patients in the short FET group, including 108 (87.1%) males and 16 (12.9%) females with a mean age of 51.8±7.9 years. There were 48 patients in the long FET group, including 44 (91.7%) males and 4 (8.3%) females with a mean age of 50.6±9.7 years. The clinical data and prognosis of the patients were analyzed. Results The mean distal stent graft was at the level of T 8.5±0.7 in the long FET group, and at the level of T 6.8±0.6 in the short FET group (P=0.001). Sixteen patients died after operation in the two groups, including 13 (10.5%) in the short FET group and 3 (6.2%) in the long FET group (P=0.561). There were 7 patients of spinal cord injury in the two groups, including 6 (4.8%) in the short FET group and 1 (2.2%) in the long FET group (P=0.675). There was no statistical difference in other complications between the two groups. The follow-up time was 16.7 (1-30) months. During the follow-up, 2 patients died in the long FET group and 5 died in the short FET group. No new spinal cord injury or distal reintervention occurred during the follow-up. Conclusion Long FET does not increase the incidence of spinal cord injury in patients with acute type A aortic dissection.
