Vascular complications during Trans Sphenoidal Surgery (TSS) can be devastating. Direct vascular injury during surgery can lead to various complications including pseudoaneurysm formation. Post-operative hematoma and direct vascular handling due to arachnoid tear can induce vasospasm. The vasospasm might present with varying clinical symptomatology and at times masks the underlying pathology as well. We present here a case of pituitary macroadenoma in whom the vasospasm not only caused vision loss but also concealed the developing pseudoaneurysm. Angiograms at regular intervals should be performed in cases where intra operative vascular injury is suspected to detect such aneurysms and prevent catastrophe.
