Abstract
Objectives:To detect the risk factors for deep venous thrombosis (DVT) in patients after neurosurgery.Methods:Three hundred and seventy-six patients treated in the department of neurosurgery of our hospital from February 2013 to November 2015 were reviewed retrospectively. The clinical data including age, gender, hospital stay, operation time, occupation type, hypertension, coronary heart disease, diabetes, smoking status, drinking status, postoperative exercises, malignant tumor, and postoperative hormone or dehydrating agent were collected.Results:In this study, 52 patients were included in the DVT group and 295 patients in the Non-DVT group. There was significant difference in age, hypertension, occupation type, malignant tumors, operation time, smoking status, and postoperative exercises between the two groups (p<0.05). However, there was no significant difference in gender, drinking status, coronary heart disease, diabetes, hospital stay, and postoperative hormone or dehydrating agent (p>0.05). In multivariate analysis, age, malignant tumor, hypertension were independent risk factors, while physical labour and postoperative exercises were protective factor for DVT.Conclusion:The postoperative patients with older age, malignant tumor or hypertension should be paid high attention to prevent DVT, and postoperative exercises should be selected as precautionary measures.
Highlights
Deep vein thrombosis (DVT) of the lower limbs is a common complication in patients suffering from surgery, and pulmonary embolism (PE) is one of the most common causes of death in patients hospitalized for surgical procedures
Those patients undergoing neurosurgical procedures are at high risk for perioperative DVT and PE, which have been reported in 6% to 43%1, even some authors stated that incidence of DVT in neurosurgical patients was as high as 18-50%, and that of PE was 0-25%
Postoperative patients in neurosurgery department need strict control of hemorrhage risk in the perioperative period, severe neurological deficits may be associated with long-term immobilization and some brain tumors are associated with state of hypercoagulability, resulting in a higher rate of DVT in neurosurgery department
Summary
Deep vein thrombosis (DVT) of the lower limbs is a common complication in patients suffering from surgery, and pulmonary embolism (PE) is one of the most common causes of death in patients hospitalized for surgical procedures. Those patients undergoing neurosurgical procedures are at high risk for perioperative DVT and PE, which have been reported in 6% to 43%1, even some authors stated that incidence of DVT in neurosurgical patients was as high as 18-50%, and that of PE was 0-25%.2. It is critical to analyze the risk factors of DVT in patients after neurosurgery
