Purpose:
Intracranial hemorrhage such as subarachnoid hemorrhage (SAH) is a rare but severe complication of spinal surgery. Current case reports of open lumbar surgery are typically accompanied by intraoperative dural tears and cerebrospinal fluid (CSF) leakage. We report a case of non-aneurysmal SAH without CSF leakage after full endoscopic transforaminal lumbar interbody fusion (FE-TLIF).
Design:
Case report and literature review.
Results:
A 62-year-old male patient underwent FE-TLIF for L4/5 lumbar spinal stenosis. There was no intraoperative dural tear or postoperative CSF leakage. The patient reported neck pain immediately after the surgery. Around 12 h after the surgery, the patient complained of mild headaches. One day after the surgery, the patient reported severe headaches, accompanied by nausea and vomiting. CT showed a high-density shadow in part of the sulcus and cistern, suggesting SAH. No apparent neurological symptoms were present. The patient's condition improved after conservative treatment including bed rest, fluid infusions, and blood pressure control. Twelve days after the surgery, CT and MRA of the brain showed no hemorrhage and the patient was discharged.
Conclusion:
This case was among the first that developed SAH without CSF leakage after FE-TLIF. Although the underlying pathologic mechanism is unknown, epidural hypertension may be a possible cause of the hemorrhage. Timely CT or magnetic resonance imaging (MRI) examinations may help to detect this complication and initiate early treatment.
