The Use of Cangrelor Infusions After Endovascular Aortic Repair With Prophylactic Lumbar Drain Placement.

ABSTRACT

Perioperative lumbar drains commonly are placed for spinal cord protection in patients undergoing endovascular aortic repair. However, the logistics of postoperative neuraxial drain removal is challenging in the presence of systemic antithrombotic therapy. This retrospective case series describes the novel use of cangrelor infusions in this high-risk setting. All lumbar drains were placed preoperatively, and descriptive data were collected including cangrelor infusion duration, time to lumbar drain removal after the infusion discontinuation, clinical course, and overall patient outcomes. There were no neurologic complications associated with lumbar drain insertion or removal, and median time to lumbar drain removal was 150 minutes after cangrelor infusion discontinuation. While further study is needed to validate its efficacy and safety, this case series highlights the promise of cangrelor infusions for systemic antithrombotic therapy in the cardiovascular/surgical intensive care unit.
