- Abstract
Background: According to the International Society on Thrombosis and Haemostasis (ISTH), intramuscular hematoma without other severity criteria is not considered a major bleeding.Objectives: In a large cohort of reversed vitamin K antagonist (VKA) patients admitted to the emergency unit for muscular hematoma, we assess frequency, severity, and anticoagulation management based on whether ISTH criteria were met or not.Materials and Methods: We performed a retrospective single-center study involving patients admitted to an emergency unit for VKA-induced intramuscular hematoma whose bleeding was reversed with prothrombin complex concentrates.Results: During the study period, 631 VKA-induced bleeding events occurred in our emergency unit, of which 73 (11.6%) were intramuscular hematomas and half met ISTH criteria. The mean age was 75.5years (95% CI=72.6-78.3). Admission blood tests showed that patients with ISTH criteria had higher international normalized ratio (7.0±4.6 vs. 4.1±3.0, p=0.002) and lower hemoglobin (8.1±1.8 vs. 11.9±2.2, p<0.001) than those without. Patients with ISTH criteria were more likely to have intramuscular hematoma in the iliopsoas, gluteal, and pectoral muscles than those without. Interestingly, two-thirds of rectus sheath hematomas involved patients without ISTH criteria. However, patients with or without ISTH criteria exhibited a similar hospitalization duration and rate of re-bleeding.Conclusion: We showed that half of the patients admitted with intramuscular hematoma could not be qualified as having ISTH-criteria major bleeding. Interestingly, these patients displayed a similar hospitalization duration and rate of re-bleeding to those with ISTH-criteria major bleeding. [ABSTRACT FROM AUTHOR]- Published
