Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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.

    5 days postoperatively

Secondary Outcomes (6)

  • incidence of myocardial injury

    first 3 days postoperatively

  • incidence of MACE

    2 years postoperatively

  • intensity of postoperative pain

    two days postoperatively

  • degree of aortic remodeling

    one month and two years postoperatively

  • 30-day mortality rate

    one month postoperatively

  • +1 more secondary outcomes

Other Outcomes (2)

  • surgical complications

    30 days after TEVAR

  • non-surgical complications

    30-days after TEVAR

Study Arms (2)

MP (experimental group)

EXPERIMENTAL

Intervention: methylprednisolone preoperatively 30 mg/kg. Patients in the MP group will receive 30 mg/kg of methylprednisolone, dissolved in 100 mL of saline, via a 30-minute slow intravenous infusion.

Drug: Methylprednisolone (MP)

Control group (placebo)

PLACEBO COMPARATOR

Patients randomized to the placebo group will receive 100 mL of physiological solution two hours prior to the intervention.

Drug: Placebo (saline)

Interventions

Patients randomized to the placebo group would receive 100 mL of physiological solution two hours prior to the intervention.

Control group (placebo)

Patients in the MP group would receive 30 mg/kg of methylprednisolone, dissolved in 100 mL of saline, via a 30-minute slow intravenous infusion.
