Usefulness of Thromboelastography for Perioperative Evaluation of Hemostatic Profile in Patients with Primary Brain Tumors Undergoing Surgery.

The K values decreased further in the postoperative period and the change was highly significant ( P < 0.001) as compared to preoperative value but not significant ( P = 0.059) when compared to intraoperative values. α-angle (which represents the speed of solid clot formation) measured at preoperative, intraoperative, and postoperative time points had mean values of 54.80 ± 5.40 min, 61.94 ± 7.87 min, and 68.57 ± 5.70 min, respectively [ Table 3 ].
