AI Article Synopsis

  • Chronic subdural hematomas (CSDHs) primarily affect elderly individuals and are typically treated with a simple burr hole surgery, though rare complications can occur, such as various types of hemorrhages.
  • An 89-year-old man with CSDH experienced right-side weakness and underwent surgery, leading to a CT scan revealing an unexpected acute intraventricular hemorrhage the next day.
  • This case highlights the unusual occurrence of intraventricular hemorrhage following CSDH drainage, potentially caused by shifts in the brain structure and increased blood flow after the procedure.

Article Abstract

Background: Chronic subdural hematomas (CSDHs) mainly occur in elderly people and usually develop after minor head injuries. CSDH can be cured by a relatively simple burr hole surgery. Rarely reported, hemorrhagic postsurgical complications include subarachnoid, intracerebral, intraventricular, and remote cerebellar hemorrhages. The causes of such uncommon complications are difficult to explain and remain poorly understood.

Case Description: We report the case study of an 89-year-old man with CSDH who presented with the right hemiparesis. He underwent burr hole surgery with a closed-drainage system. A computed tomography (CT) scan conducted the following day demonstrated an acute intraventricular hemorrhage and hyperperfusion of the ipsilateral hemisphere.

Conclusion: This is a rare case of an acute hematoma in the ventricle following drainage of a CSDH. The likely mechanism of this intraventricular hemorrhage could be that the drainage of the hematoma produced a movement of the ventricle and hemisphere accompanied by hyperperfusion.

Background: Burr holes can lead to cranial defects that result in cosmetic and functional issues. Effective reconstruction of these burr holes is crucial for improving patient outcomes, yet there is no consensus on the optimal techniques and materials.

Objective: This systematic review critically evaluates the efficacy and safety of various materials used in neurosurgical practice for burr hole reconstruction.

Germ cell tumors (GCTs) commonly develop in the pineal and suprasellar regions, with the most common GCTs being germinomas. In this report, a 22-year-old male presented with progressive right-sided weakness, and his imaging was consistent with a left thalamic high-grade glioma. A stereotactic biopsy was performed, revealing a germinoma, but radiation therapy was not done, and the patient was lost to follow-up.

Background: The main surgical interventions for chronic subdural hematoma (CSDH) include craniotomy for hematoma evacuation, neuroendoscopic hematoma evacuation, and burr hole drainage.However, elderly patients often present with significant comorbidities, which limit their ability to tolerate general anesthesia and invasive surgical procedures.Minimally invasive soft-channel drainage under local anesthesia has emerged as a viable alternative, particularly suitable for elderly patients or those with high surgical risk.
