OBJECTIVE: Pituitary adenoma (PA) is the most frequent tumor in the sellar region. Arginine vasopressin deficiency (AVP-D), formerly known as central diabetes insipidus, is a common complication after pituitary surgeries. In this study, we reviewed patients with PAs after endoscopic transsphenoidal surgery, evaluated the incidence of postoperative AVP-D, and determined associated risk factors.
METHODS: We retrospectively studied 520 patients who underwent endoscopic transsphenoidal surgery for PAs and evaluated perioperative risk factors and their associations with postoperative AVP-D. Patients who developed AVP-D were categorized in 3 groups: (1) early AVP-D, (2) transient AVP-D, and (3) permanent AVP-D.
RESULTS: Of the 520 patients, 24.8% experienced early AVP-D, and 1.9% (n = 10) had transient AVP-D. Permanent AVP-D was observed in only 6 patients (1.1%). Gross total resection, hormonal remission, pituitary stalk manipulation, and intraoperative cerebrospinal fluid leak were significantly associated with a higher incidence of AVP-D (P = .027, P = .002, P < .001 and P < .001, respectively). All patients who developed permanent AVP-D had somatotroph adenomas. AVP-D was not found to be related with tumor size. The length of hospital stay was prolonged by AVP-D on average by 1.5 days (P = .018).
CONCLUSION: The reported incidence of AVP-D has a considerably wide range. A consistent definition and grading for AVP-D will increase consistency and comparability among studies. Nonetheless, most patients experience AVP-D on a temporary basis, and only a few require long-term treatment. Cerebrospinal fluid leak, gross total resection, and hormonal remission were identified as risk factors for postoperative AVP-D. We believe that the intraoperative risk factors play the main role in postoperative AVP-D. The course of surgery and operative findings help us plan selective postoperative patient monitoring and care.
