Analysis of risk factors for traumatic intraparenchymal contusions and hematomas progression in patients with non-emergency craniotomy / 中国医师进修杂志

ABSTRACT

Objective:To observe the natural course of patients with simple traumatic intraparenchymal contusions and hematomas (TIPHs), and analyze the risk factors for TIPHs progression.Methods:Using a prospective observational study, 69 patients with TIPHs in Affiliated Xiaolan Hospital, Southern Medical University from July 2018 to January 2020 were selected. The gender, age, cause of injury, compound injury status, combined injury and Glasgow coma score (GCS) were recorded. The plasma levels of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fbg), international normalized ratio (INR), D-dimer, platelet, hemoglobin at admission were detected. The occurrence of hypoxemia and high intracranial pressure were observed. The time of the first CT examination, volume of the first CT hematoma, time of the control CT examination, volume of the control CT hematoma, and lesion morphology, multifocality, subarachnoid hemorrhage (SAH), edema zone and cortical distance showed in the first CT examination were recorded. The risk factors of progression in patients with TIPHs were analyzed.Results:Among 69 patients with TIPHs, TIPHs progression was in 28 cases (progression group), and the progression rate was 40.58%; TIPHs progression was not in 41 cases (non-progression group). There were no statistical differences in gender composition, age, PT, APTT, INR, hemoglobin, cause of injury, compound injury, incidence of hypoxemia, incidence of high intracranial pressure, incidence of SAH, incidence of edema zone, incidence of irregular lesions, time of the first CT examination, time of the control CT examination and volume of the first CT hematoma between 2 groups ( P>0.05). The GCS, cortical distance and Fbg in progression group were significantly lower than those in non-progression group, the TT, platelet, multifocality rate and volume of the control CT hematoma were significantly higher than those in non-progression group, and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that cortical distance <1 cm, Fbg<2 g/L and multifocality were independent risk factors affecting the progression in patients with TIPHs ( OR = 6.723, 5.515 and 4.827; P<0.05). The model had a sensitivity of 71.43% (20/28), a specificity of 92.68% (38/41), and an accuracy of 84.06% (58/69) in judging the progression of TIPHs. Conclusions:Based on the risk factors for the progression of TIPHs, predicting these patients in advance can provide necessary intervention measures for high-risk patients, which will help to reduce the rate of progression and improve the prognosis of patients.
