New parameter of hemoglobin status as an indicator of efficacy of preoperative angioembolization in extracranial hypervascular tumours. | LitMetric

Background: Routinely, the standard for measuring the success of preoperative embolization procedure as an adjunct in the management of head and neck vascular tumours has been to evaluate the amount of blood loss, duration of surgery, and intraoperative neurovascular injuries.

Objective: We hypothesized that the rate of change in the preoperative hemoglobin status would more accurately and objectively reflect the effectiveness of the embolization technique.

Materials And Methods: Twenty-six patients with extracranial vascular tumours were divided into two groups (A and B) of 13. Group A patients had preoperative embolization and group B patients directly underwent surgery. The difference between the preoperative and postoperative hemoglobin levels and the percentage rate of change of hemoglobin status were calculated.

Results: The percentage rate of change of preoperative to postoperative hemoglobin is less in group A (9.43%) when compared with group B (18.27%). The ratio of preoperative to postoperative hemoglobin in the two groups is also statistically significant (1:1.9).

Conclusions: The percentage rate of change of preoperative to postoperative hemoglobin and the ratio of preoperative to postoperative hemoglobin are more accurate and objective parameters for assessment of success of preoperative embolizations rather than other variables such as intraoperative blood loss or duration of surgery.
