About this trial
Postimplantation syndrome (PIS) is a common and clinically important complication following thoracic endovascular aortic repair (TEVAR). PIS is characterized by a strong systemic inflammatory response to the stent-graft implantation and is manifested by flu-like symptoms, which include fever, increased white blood count, increased levels of acute phase proteins, and fatigue, but without a clear inflammatory and infective cause. Besides, it has been demonstrated that PIS is associated with prolonged hospital stay and increased risk for postoperative complications, including acute kidney injury, postoperative delirium, and increased postoperative pain scores. Recently, there has been increasing evidence that PIS is associated with an increased risk of major adverse cardiac events (MACE) and perioperative myocardial injury. Observational studies suggest that preoperative administration of glucocorticoids may decrease the incidence of PIS after TEVAR and EVAR procedures. However, to date, there are no randomised trials that have investigated whether preoperative administration of glucocorticoids can reduce the incidence of PIS and its associated poorer treatment outcomes following TEVAR. This randomized controlled trial was designed to investigate the effect of glucocorticoid administration on reducing the incidence and improving the outcome of patients who develop PIS after TEVAR.

Trial design
Parallel
Treatments tested in this trial
Methylprednisolone (MP)
DrugPatients in the MP group would receive 30 mg/kg of methylprednisolone, dissolved in 100 mL of saline, via a 30-minute slow intravenous infusion.
Placebo (saline)
DrugPatients randomized to the placebo group would receive 100 mL of physiological solution two hours prior to the intervention.
Treatment groups
Trial outcomes
Primary outcomes
Incidence of PIS
Post-implantation syndrome would be defined as the occurrence of elevated body temperature (\>38.0°C), with the presence of leukocytosis (\>12,000/mm³), and an increase in the level of C-reactive protein (\>10g/L) during the first five days postoperatively, despite negative blood cultures.
Secondary outcomes
incidence of myocardial injury
Myocardial injury would be defined as an increase in the level of hs-TnI above the 99th percentile of the upper reference limitwithout clinical signs of acute myocardial ischemia, during the first three postoperative days.
incidence of MACE
MACE events would be defined as a composite outcome that includes the occurrence of myocardial infarction, acute heart failure, malignant rhythm disorders, and cardiovascular death during two years after TEVAR.
intensity of postoperative pain
The intensity of postoperative pain will be measured using the Numeric Rating Scale - NRS, during 48 hours postoperatively.
degree of aortic remodeling
Degree of aortic remodeling will be assessed based on CT evaluation of the aorta) one month and two years after TEVAR
Other outcomes
surgical complications
Postoperative surgical complications will be defined as complications related to the surgical procedure within 30 days after the operation.
non-surgical complications
Postoperative non-surgical complications will be defined as complications which are not related to surgical procedures/techniques and are related to patients' physiological status or comorbidities.
