Abstract:

Objective

To analyze the risk factors for postoperative deep venous thrombosis (DVT) in patients with basal ganglia hemorrhage (BGH).

Methods

The clinical data of patients with basal ganglia cerebral hemorrhage who were treated surgically between May 2020 and December 2023 in the Northern Jiangsu People's Hospital Affiliated to Yangzhou University were retrospectively analyzed. The patients were divided into DVT group and non-DVT group according to whether DVT was formed in the lower limbs after surgery. The clinical data of the 2 groups were compared, and the risk factors for postoperative lower limb DVT in BGH patients were identified using multivariate logistic regression analysis.

Results

A total of 300 BGH patients were included in this group, including 72 cases in the DVT group and 228 cases in the non-DVT group. There was a statistically significant difference (P<0.05) in age, body mass index (BMI), preoperative pulse pressure, intraoperative blood transfusion, surgical season, postoperative use of dehydrating drugs, site of venous catheterization, duration of venous catheterization, preoperative activated partial thromboplastin time, preoperative D-dimer levels, and preoperative blood chloride levels between the two groups of patients. Further multivariate logistic regression analysis showed that age≥65 years, BMI, surgical season (spring and winter), postoperative hormone use, intravenous catheterization time>3 d, preoperative D-dimer>2 μg/mL, and preoperative blood chloride>107 mmol/L were independent risk factors for lower limb DVT in BGH patients after surgery (P<0.05).

Conclusions

The independent risk factors for postoperative lower limb DVT in BGH patients include age≥65 years, BMI, surgical season (spring and winter), postoperative hormone use, intravenous catheterization time>3 d, preoperative D-dimer>2 μg/mL, and preoperative blood chloride>107 mmol/L. Clinical measures should be taken for early identification and treatment to reduce the incidence of DVT and improve the prognosis of patients.
