NEUROLOGICAL COMPLICATIONS AFTER THORACIC AORTIC SURGERY WITH FROZEN ELEPHANT TRUNK TECHNIQUE
Main Article Content
Abstract
Objectives: To study the neurological complications occurring in patients, underwent surgery for thoracic aortic disease using frozen elephant trunk (FET) technique at Viet Duc university hospital and review the literature. Methods: Retrospective description of clinical cases undergoing surgery for thoracic aortic disease with FET technique with neurological complications from 12/2019 to 12/2021. Results: Among 42 cases of complex thoracic aortic disease operated with FET technique, there were several types of neurological complications, including: 1 case (2.4%) temporary spinal cord paralysis; 3 cases (7.1%) of cerebrovascular accident; 5 cases (11.9%) had transient neurological dysfunction (excitement, delirium...). There were no cases of recurrent laryngeal or phrenic nerve paralysis. One death (2.4%) was in a deep coma after a cerebrovascular accident. Conclusion: Neurological complications after surgery for thoracic aortic disease using FET technique at Viet Duc hospital are rare and are equivalent to those published in the world, in which dysfunction transient neurosis (excitatory) is the most common.
