Summary
Cerebral venous infarction is a rare but serious complication of deep brain stimulation (DBS) surgery. Careful surgical planning using advanced imaging can help prevent this adverse event.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Deep brain stimulation (DBS) is a common treatment for Parkinson's disease.
- While generally safe, DBS surgery carries risks, including rare complications like cerebral venous infarction.
Observation:
- Four cases of cerebral venous infarction occurred following DBS lead implantation.
- This complication was identified in 0.8% of leads and 1.3% of patients.
Findings:
- Venous infarction presented with delayed neurological deficits and edema on CT scans.
- In two cases, planned trajectories were close to cortical veins, suggesting a link to lead placement.
Implications:
- Cerebral venous infarction is a potentially avoidable complication of DBS.
- High-resolution, contrast-enhanced MRI for venous anatomy and meticulous stereotactic planning are recommended to minimize risk.

01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
