Neurologic Complications After the Frozen Elephant Trunk Procedure: A Meta-Analysis of More Than 3,000 Patients

Dr Preventza and associates performed a meta-analysis of 3,154 patients who underwent frozen elephant trunk procedure to determine the incidence of neurologic complications. The incidences were 4.7% for spinal cord injury and 7.6% for stroke. Operative mortality was 8.8%.  Stent longer than 15 cm or coverage of T8 and beyond was assoicated with a higher incidence of spinal cord injury compared to stent length of 10 cm.
