Summary

Approximately 24.5% of patients undergoing aneurysm surgery received intraoperative blood transfusions. Reducing intraoperative aneurysm rupture could decrease the need for blood products in these neurosurgical procedures.

Area of Science:

  • Neurosurgery
  • Transfusion Medicine
  • Critical Care

Background:

  • Rising healthcare costs and blood supply safety concerns necessitate reevaluation of transfusion practices.
  • Aneurysm surgery presents unique challenges regarding blood loss and transfusion needs.
  • This study investigates blood utilization patterns in patients undergoing cerebral aneurysm surgery.

Purpose of the Study:

  • To analyze the incidence and predictors of intraoperative and postoperative blood transfusions in aneurysm surgery.
  • To identify factors associated with increased blood product requirements during and after aneurysm repair.
  • To inform strategies for optimizing blood management in neurosurgical interventions.

Main Methods:

  • Retrospective analysis of 547 patients undergoing surgery for cerebral aneurysms.

  • Review of operative, anesthetic, nursing records, CT scans, and angiographic films.
  • Data collected during a period with a consistent transfusion threshold.

    • Main Results:

    • 24.5% of patients received intraoperative transfusions; 44.6% received postoperative transfusions.
    • Preoperative factors linked to intraoperative transfusion included older age, lower hematocrit, aneurysm rupture, intraventricular hemorrhage, and larger aneurysm size.
    • Intraoperative rupture, hematoma evacuation, and multiple aneurysm obliteration were associated with transfusion; ruptured aneurysms required more blood.
    • Postoperative transfusion was linked to subarachnoid hemorrhage treatment, especially in poor-grade patients with complications.

    Conclusions:

    • Blood transfusion is common in aneurysm surgery, affecting about one in five patients intraoperatively.
    • Minimizing intraoperative aneurysm rupture may significantly reduce the demand for blood products.
    • Optimized transfusion strategies are crucial for managing blood loss in complex neurosurgery.
