These hemorrhagic venous complications are very rare and often grouped as all hemorrhagic complications. We report the clinical cases of 2 patients with Parkinson’s disease (PD) who received unilateral globus pallidus DBS and developed hemorrhagic venous infarctions. In these 2 patients a small injury to a dural outflow venous structure or a superficial brain vein resulted in hemorrhagic venous infarctions. We present the management of these rare complication with detailed radiologic follow-up. The first patient made a full recovery but the second patient deceased 5 months after DBS surgery due to aspiration pneumonia. We stress that careful planning of a stereotactic trajectory reduces significantly hemorrhagic complications in DBS surgery but not fully exclude some side effects like venous hemorrhagic infarctions which may result in prolong hospitalization or death.
