Vasospasm following transcranial removal of large pituitary adenomas. Report of three cases.
The authors report three cases of cerebral vascular spasm following transfrontal removal of large pituitary neoplasms. One patient awakened from surgery hemiparetic, but has since recovered. A second patient developed hemiparesis with confusion on the fifth postoperative day and eventually died. The third patient developed hemiplegia on the tenth postoperative day, but recovered completely. Vascular spasm was documented angiographically in all three cases. Possible mechanisms underlying this unusual complication are discussed.
