Main objective

Scope: Efficacy

The primary objective of the study is to assess the time from hospital arrival to revascularization in patients with acute ischemic stroke treated with mechanical thrombectomy, depending on whether the procedure was performed under sedation with HFNC or under general anesthesia.
Monitor CMV-specific cellular immune response before transplantation and at 15, 30 and 90 days post-transplantation in each of the two treatment groups using Quantiferon-CMV.

Secondary objectives 2

  1. To compare between the two groups the incidence of delayed initial graft function, acute rejection diagnosed by renal biopsy, renal function and patient and graft survival in the first 6 months post-transplantation.
  2. To compare between the two groups the presence of surgical (lymphocele requiring intervention) or hematological (neutropenia) complications in the first 6 months post-transplantation.
