Risk factors and prophylaxis for deep venous thrombosis in neurosurgery

Area of Science:

• Neurosurgery
• Vascular Surgery
• Oncology

Background:

• Pharmacological prophylaxis for deep vein thrombosis (DVT) and pulmonary embolism (PE) is widely accepted for most surgeries.
• Its use in neurosurgery is debated due to hemorrhage risks, leading to preference for mechanical methods like compression devices.
• Some high-risk neurosurgical patients may still require anticoagulants like low molecular weight heparin (LMWH) or unfractionated heparin (UFH).

Observation:

• Known DVT/PE risk factors in neurosurgery include advanced age, malignancy, limb weakness, prolonged procedures, and cranial surgery.
• This research utilizes comprehensive neurosurgery databases to pinpoint specific diagnostic and procedural risk factors.
• The study observes increasing frequencies of DVT and PE in the general neurosurgery population and specifically in glioma patients over time.

Findings:

• Identifies specific neurosurgical diagnoses and procedures that elevate DVT and PE risk.
• Demonstrates an increasing incidence of DVT and PE within the broader neurosurgical patient cohort.
• Highlights a temporal increase in DVT and PE occurrence among patients with gliomas.
• Compares the utilization of DVT prophylaxis across public and private hospital settings.

Implications:

• Findings may inform revised DVT/PE prophylaxis guidelines for neurosurgical patients.
• Highlights the need for tailored risk assessment and management strategies in neurosurgery.
• Contributes to understanding the evolving landscape of thromboembolic events in neurosurgical care over two decades.
