Cerebral venous sinus thrombosis following transsphenoidal surgery for craniopharyngioma: A case report

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a rare condition in patients with craniopharyngioma following transsphenoidal surgery. CASE SUMMARY: A 56-year-old man who underwent transsphenoidal surgery for craniopharyngioma 26 d ago presented gradual headache and cerebrospinal fluid leakage while vomiting 5 d post-discharge and required readmission to our department of neurosurgery. After admission, head imaging examination showed a hyperdense shadow in the superior sagittal sinus and right transverse sinus, edema at the bilateral parietal lobe, and hemorrhage at the left parietal lobe and right occipital lobe; the venous phase of cerebral angiography revealed CVST. The patient was treated immediately by intravenous thrombolysis, endovascular thrombolysis, and mechanical thrombectomy after the definite diagnosis. However, the neurological status of the patient continued to deteriorate and he died on the fourth day after readmission. CONCLUSION: For craniopharyngioma undergoing transsphenoidal surgery, it is vital to take an effective strategy to manage the postoperative complications, such as diabetes insipidus, severe electrolyte imbalance, and cerebrospinal fluid leakage. Additionally, the early differential diagnosis of CVST is essential when it develops clinical symptoms, especially in patients following transsphenoidal surgery with a high risk of CVST. Subsequently, the timely and effective treatment of the CVST is critical for preventing neurological deterioration.
