Abstract
Abstract
Objective: Paralysis post TEVAR is a devastating complication, this study discusses its incidence, Risk factors, clinical outcome, reversibility, protective strategy and associated mortality.
Methods:
Retrospective study Conducted on patients underwent thoracic and thoracoabdominal aortic Aneurysm Endovascular Repair in Last 11 years (January 2012 till June 2022) in single center as regard incidence, personal history, medical and surgical risk factors, preventive strategies, reversibility of paralysis and associated mortality. Data was obtained from records; paralysis was diagnosed through clinical examination immediately after emergence from anesthesia and frequently post operatively in SICU or even word and after discharge in follow-up outpatient clinic visits.
Results:
A study carried on 137 patients, 15 patients of them developed lower limb paralysis with incidence of 10.9%, 3 patients of them (23.1%) developed paralysis immediately post operative, 4 patients developed paralysis in day 1 post operative (30.8%). And the rest of patients developed delayed onset paralysis (more than 24 Hour post procedure) , The latest one developed paralysis 26 days post operative, 8 of paralyzed patients had spinal cord imaging (MRI) 4 of them (50%) didn’t show any abnormality and 3 of them (37.5%) showed spinal cord ischemia and 1 patient didn’t tolerate the MRI machine so the study was discontinued. According to reversibility, 9 patients had complete reversal of their motor and sensory symptoms to the baseline preoperative status. 2 patients had partial reversal of their symptoms, and 4 patients had persistent symptoms without any improvement despite the routine management that included elevating MAP and draining CSF to less than 10 mmHg in order to maintain spinal cord perfusion pressure at level of 80 mmHg and giving naloxone. Data showed 12 out of 81 patients (14.8%) who had functioning spinal drain developed paralysis. Duration of procedure is the most affecting risk factor on paralysis, patients with mean duration of 270 minutes had higher risk of paralysis.
Conclusion:
Prediction of paralysis post TEVAR is still difficult and data analysis showed that the duration of procedure is the only statistically significant variable that we can rely on.
