Abstract:
We report a rare case of anterior cerebral artery (ACA) thrombosis following transsphenoidal surgery in a case of growth hormone secreting pituitary macroadenoma. During the surgery, there was arachnoid breach with cerebrospinal fluid (CSF) leak. Post operatively, she became blind in both eyes for which re-exploration was done. A computed tomographic (CT) scan 16 hours after surgery showed a large tumor bed haematoma which was explored transcranially. During surgery, the right A1 was thrombosed while the ICA and middle cerebral artery (MCA) were patent as confirmed by post-operative magnetic resonance imaging (MRI). However, she died on the second post-operative day. ACA thrombosis following transsphenoidal surgery has not been reported before. A review of literature and possible mechanism of this complication has been discussed.
