Incidence and Management of Complications of Transsphenoidal Operation for Pituitary Adenomas

Abstract

Abstract Two hundred fifty-five consecutive transsphenoidal procedures for pituitary adenomas were reviewed to evaluate complications and their management. There were no operative deaths. Cerebrospinal fluid (CSF) rhinorrhea was the most common complication, occurring in 2.7% of cases; diabetes insipidus was next, lasting less than 1 year in 1.6% of patients and over a year in 0.4%. Sinusitis occurred in 1.2% of patients, and delayed epistaxis occurred in 0.8%. Postoperative hematomas, meningitis, hydrocephalus, and deep venous thrombosis each occurred in 0.4% of cases. These results are discussed in the context of previous reports, including an international survey of pituitary surgeons. Although transsphenoidal surgery has a low morbidity and mortality, it is nevertheless associated with potentially serious difficulties that should be expeditiously recognized and managed.
