Object. Transsphenoidal surgery is the usual treatment of choice for adrenocorticotropic hormone—secreting pituitary adenomas associated with Cushing's disease. In this paper the authors investigate the complications of transsphenoidal surgery in the treatment of a contemporary series of patients with Cushing's disease.Methods. Between January 1992 and December 1997, 105 patients with Cushing's disease underwent transsphenoidal surgery at the University of Virginia Health Sciences Center. A retrospective analysis of the complications was conducted, and the mortality rate was found to be 0.9% and permanent morbidity was 1.8%. The overall number of complications was 14 (13.3%), which included seven complications directly related to surgery; one instance of permanent diabetes insipidus; one syndrome of inappropriate secretion of antidiuretic hormone; and five medical complications (four patients developed deep vein thrombosis and one developed pneumonia).Conclusions. Transsphenoidal surgery for Cushing's disease has a higher complication rate than that for pituitary adenomas in general. This is primarily related to a greater number of medical complications, most notably deep vein thrombosis, resulting from the generally debilitated state of most patients with Cushing's disease. In view of the high incidence of deep vein thrombosis in these patients, prophylaxis for thromboembolism during the perioperative period is recommended.

Object. Although transsphenoidal surgery has become the standard of care for Cushing's disease, it is often unsuccessful in normalizing cortisol production. In this study the authors investigate the safety and efficacy of gamma knife radiosurgery (GKRS) for Cushing's disease after failed transsphenoidal surgery.Methods. The records of all patients who underwent GKRS at the authors' institution after unsuccessful transsphenoidal surgery for Cushing's disease were retrospectively reviewed. Successful treatment was considered a normal or below-normal 24-hour urinary free cortisol (UFC) level. Records were also evaluated for relapse, new-onset endocrine deficiencies, interval change in tumor size, and visual complications.Forty-three patients underwent 44 gamma knife procedures with follow up ranging from 18 to 113 months (mean 39.1, median 44 months). Normal 24-hour UFC levels were achieved in 27 patients (63%) at an average time from treatment of 12.1 months (range 3–48 months). Three patients had a recurrence of Cushing's disease at 19, 37, and 38 months, respectively, after radiosurgery. New endocrine deficiencies were noted in seven patients (16%). Follow-up magnetic resonance images obtained in 33 patients revealed a decrease in tumor size in 24, no change in nine, and an increase in size in none of the patients. One patient developed a quadrantanopsia 14 months after radiosurgery despite having received a dose of only 0.7 Gy to the optic tract.Conclusions. Gamma knife radiosurgery appears to be safe and effective for the treatment of Cushing's disease refractory to pituitary surgery. Delayed recurrences and new hormone deficiencies may occur, indicating the necessity for regular long-term follow up.

Object. Clinically evident multiple pituitary adenomas rarely occur. The authors assess the incidence and clinical relevance of multiple adenomas in Cushing's disease.Methods. A prospective clinical database of 660 pituitary surgeries was analyzed to assess the incidence of multiple pituitary adenomas in Cushing's disease. Relevant radiographic scans, medical records, and histopathological reports were reviewed.Thirteen patients with at least two separate histopathologically confirmed pituitary adenomas were identified. Prolactinomas (nine patients) were the most common incidental tumors. Other incidental tumors included secretors of growth hormone ([GH], one patient) and GH and prolactin (two patients), and a null-cell tumor (one patient). In two patients, early repeated surgery was performed because the initial operation failed to correct hypercortisolism, in one instance because the tumor excised at the initial surgery was a prolactinoma, not an adrenocorticotropic hormone—secreting tumor. One patient had three distinct tumors.Conclusions. Multiple pituitary adenomas are rare, but may complicate management of patients with pituitary disease.

Object. Pituitary surgery has been reported to produce remission of Cushing's disease with preservation of pituitary function in only 60 to 70% of patients. The inability to identify an adenoma accounts for most failed sellar explorations. Most negative surgical explorations occur in patients in whom magnetic resonance (MR) imaging of the pituitary demonstrates normal findings, which happens in at least 35 to 45% of patients with Cushing's disease. Methods. To examine the usefulness of intraoperative ultrasonography (IOUS) for identifying an adenoma in patients with no demonstrable tumor (negative findings) on pituitary MR imaging, we prospectively assessed the results of IOUS in 68 patients with a negative (59 patients) or equivocal (nine patients) MR image from a consecutive series of 107 patients with Cushing's disease (64%). We compared surgical findings and outcomes in these 68 patients with a group of 68 patients with Cushing's disease and negative findings on MR imaging in whom IOUS was not available. Intraoperative ultrasonography localized a tumor in 47 (69%) of 68 patients with negative findings on MR imaging. Surprisingly, the size of the adenomas that were detected with IOUS compared with the size of those not detected did not differ (6.8 ± 3.4 mm compared with 6.1 ± 2.8 mm [mean ± standard deviation], respectively [p = 0.5]). In four patients, no adenoma was found at surgery or in the pathological specimen (“true negative”). In eight patients, nine abnormalities detected by IOUS that were suspected adenomas were negative on exploration (“false positive”). Thus, IOUS has a sensitivity of 73% and a positive predictive value of 84% for detecting pituitary adenomas in patients with Cushing's disease and negative findings on MR imaging. Compared with the 68 patients who did not undergo IOUS, remission after surgery was improved (61 patients [90%] compared with 57 patients [84%]), the number of tumors found on exploration was increased (61 tumors compared with 51 tumors; p = 0.02), and the number of hemihypophysectomies was decreased (five compared with 15; p = 0.02) with IOUS. When the groups were compared after excluding patients with prior pituitary surgery, tumors were found in 91% versus 72% (p = 0.008), and remission occurred in 95% versus 87% of patients, respectively, in the groups that had or did not have IOUS. Conclusions. The IOUS is a sensitive imaging modality when used in patients with Cushing's disease in whom findings on pituitary MR imaging are negative. The improved ability to detect and localize these tumors by using IOUS positively affects surgical outcome.

✓ Transsphenoidal resection of adrenocorticotrophic hormone (ACTH)-producing pituitary adenomas has the potential of curing most patients with Cushing's disease. However, transsphenoidal exploration of the pituitary is not always curative, and patients who have remission of hypercortisolism following surgery occasionally develop a recurrence. Whether repeat pituitary surgery should be performed for recurrent or persistent Cushing's disease has not been evaluated previously. To determine the efficacy of transsphenoidal surgery in recurrent or persistent Cushing's disease, we performed transsphenoidal surgery in 31 patients (22 women and nine men) who had previously undergone a transsphenoidal operation and two female patients who had had previous pituitary irradiation only. In 24 (73%) of the 33 patients, remission of hypercortisolism was achieved by surgery. Although preoperative computerized tomography (CT) scanning identified an adenoma in only three of the 33 patients, in 20 patients a discrete adenoma was identified at pituitary exploration. The incidence of remission of hypercortisolism was greatest if an adenoma was identified at surgery and the patient received selective adenomectomy (19, or 95% of 20 patients), if there was evidence at surgery or by preoperative CT scanning that the previous surgical exposure of the pituitary was incomplete (seven, or 78% of nine patients), if an adenoma was seen on preoperative CT scanning (three of three patients), or if the patient had had prior pituitary irradiation without surgery (two of two patients). In contrast, only five (42%) of 12 patients who received subtotal or total hypophysectomy had remission of hypercortisolism. Surgically induced hypopituitarism occurred in six (50%) of these 12 patients, but in only one (5%) of the 20 patients who underwent selective adenomectomy. Three (13%) of the 24 patients who were in remission from hypercortisolism following repeat surgery developed recurrent hypercortisolism 10 to 47 months postoperatively. Repeat transsphenoidal exploration of the pituitary and treatment limited to selective adenomectomy should be considered in patients with hypercortisolism despite previous pituitary treatment. If an adenoma is identified during surgery, the chance of remission of Cushing's disease is high and the risk of hypopituitarism is low; however, if no adenoma can be found and partial or complete hypophysectomy is performed, remission of hypercortisolism is less likely and the risk of hypopituitarism is about 50%.

✓ Transsphenoidal microdissection has been proposed as a preferred means of treating Cushing's disease. This procedure allows the surgeon to remove a pituitary microadenoma and at the same time to preserve normal tissue. Two cases described here were treated by this method. An interesting and important observation was that neither patient appeared to be cured for 2 to 6 weeks after surgery, as assessed by dexamethasone suppression. Later, normal suppressibility occurred and the course of each patient was compatible with cure. Patients treated by this method should not be automatically retreated because of adrenocorticotropic hormone (ACTH) non-suppressibility in the early postoperative period.

✓ A new sequential pneumatic instrument for the prevention of deep vein thrombosis (DVT), the Lympha Press, was investigated in neurosurgical patients. In the control group, 50% of patients developed DVT and in the treated group only 4.3% were affected. These results demonstrate the highly beneficial effect of this method of preventing DVT during and after surgery, especially when the use of other preventive methods is precluded.

✓ The potential efficacy of early repeat transsphenoidal surgery for persistent Cushing's disease has not previously been examined. On 222 patients with no prior pituitary treatment and a preoperative diagnosis of Cushing's disease, 29 (13%) remained hypercortisolemic after an initial transsphenoidal pituitary exploration. Seventeen of these 29 patients underwent further surgery 7 to 46 days after the initial transsphenoidal approach in order to completely excise suspected residual tumor. Patients were followed for 4 to 84 months (mean ± standard deviation, 34 ± 25 months) to document sustained remission or recurrence of Cushing's disease (a urine free cortisol level > 90 µg/day was considered evidence of recurrence). Of the 17 patients with repeat surgery, 12 (71%) had resolution of hypercortisolism (morning plasma cortisol level < 5 µg/dl); however, in three of these 12, hypercortisolism recurred 5, 12, and 24 months later. In 14 patients a lesion that appeared to be a tumor was identified during the initial procedure or on histological examination. Of these, 12 had immediate resolution of hypercortisolism and nine are still in remission. Three patients, in whom no adenoma could be identified during the initial surgery or an examination of the partial hypophysectomy specimen from the initial surgery, had persistent Cushing's syndrome after the second operation. Seven (41%) of the 17 patients developed hypopituitarism requiring treatment with thyroid hormone, gonadal steroid, or vasopressin replacement. The low incidence of identification of an adenoma on computerized tomography or magnetic resonance images (three of 17 patients), the failure to find a corticotrophic adenoma during the initial surgery (10 of 17 patients), and the failure of these 17 patients to respond to the initial transsphenoidal surgery suggest that they may comprise a subset of patients who are more difficult to treat successfully with surgery than most patients with Cushing's disease. Despite that, early reoperation induced immediate remission of hypercortisolism in 71% of cases, but did so at the expense of a high risk of hypopituitarism. However, since the alternative treatments (such as radiation therapy, long-term drug therapy, or bilateral adrenalectomy) also have potential adverse effects, early reoperation deserves consideration for the management of persistent Cushing's disease, especially when an adrenocorticotrophic hormone-secreting adenoma was partially excised during the first surgery.

Transsphenoidal Resection

✓ A patient with a pituitary adenoma secreting adrenocorticotropin hormone manifested panhypopituitarism after an episode of pituitary apoplexy. The previously elevated urinary levels of 17-ketogenic steroids dropped sharply, and plasma cortisol became undetectable. The apoplexy also resulted in a partially empty sella on which the dorsum sellae collapsed. Recurrent Cushing's disease developed and was cured by transsphenoidal resection of a microadenoma.
