Risk factors for deep venous thrombosis of lower limbs in postoperative neurosurgical patients

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.

Analysis of the occurrence of deep venous thrombosis in lower extremity fractures: A clinical study

“…Many authors also advocated that old age was an important risk factor for DVT because of vascular sclerosis, high blood viscosity and poor venous valve function in old patients. 4 , 13 , 14 At the same time, in a retrospective study of 276 old patients with hip fracture, Li also suggested that hip arthroplasty and longer operation time had significant correlation with the occurrence of DVT, highlighting the similar viewpoints. 13…”

“…In our previous study of 376 postoperative neurosurgical patients, we had the same conclusion. 4 Those mental workers usually keep on sitting in their daily life, and the prolonged work- and computer-related seated immobility was significantly associated with an increased risk of DVT. In terms of the postoperative exercises, in a study of 80 patients, Tominaga found that the preoperative walking disability was risk factor for DVT and VTE, and gait training during the early postoperative period is recommended to prevent VTE, also suggesting the same viewpoints.…”

“… 3 In clinical practice, DVT is often asymptomatic and in many patients the fatal pulmonary embolism is usually the first clinical manifestation. 4 Many prophylactic methods for DVT, such as low dose heparin, aspirin, elastic stockings and intermittent pneumatic calf compression, have been employed widely in orthopedics department, but DVT is still a common dangerous postoperative complication. 5 Subsequently, it is critical to study its distribution characteristics and related risk factors of DVT in lower extremity fractures to prevent and reduce its occurrence in orthopedics department.…”

Study on the Risk Factors of Deep Vein Thrombosis (DVT) in Patients With Lower Extremity Fracture

“…In the opinion of the present authors, there are more internal diseases in elderly patients, which results in a longer preparation time for surgery and longer preoperative resting time. Moreover, elderly patients often have vascular sclerosis, high blood viscosity, and poor venous valve function, which lead to a high incidence of lower extremity DVT [17] . Moreover, similar to the ndings of the present study, Li et al found that femoral neck fractures and intertrochanteric fractures are more common in older patients, and that many patients with these fractures choose arthroplasty surgery, which also increases the risk of DVT [8] .…”

Impaired contraction of blood clots precedes and predicts postoperative venous thromboembolism

“…Several clinical factors have been shown to be somewhat predictive of the postoperative VTE risk and have helped to identify postcraniotomy patients who particularly need postoperative precautionary measures 22 . These patients include those with older age, higher BMI, malignant tumor or hypertension 23 . Also, there is a direct correlation between the operation time and DVT incidence 12 .…”
