Expanded endoscopic endonasal approach for resection of residual parasellar growth hormone-secreting pituitary adenoma in a patient with kissing internal carotid arteries: Technical nuances.

ABSTRACT:

Background

Growth hormone (GH)--secreting pituitary adenomas can be aggressive and difficult to manage. Surgical resection for GH-secreting tumors remains the gold standard with increasing use of expanded endoscopic endonasal (EEA) techniques. Certain anatomical considerations make postsurgical biochemical remission challenging.

Case description

We describe the case of a 43-year-old male presenting with acromegaly after a lack of biochemical remission from a previous surgery. Resection of the residual tumor invading the retrogenu compartment of the cavernous sinus was challenging for several reasons: (a) its location adjacent to the right parasellar horizontal internal carotid artery (ICA) with involvement of the medial wall, (b) the large kissing bilateral ICAs reducing the
