ObjectiveCure rate for primary hyperparathyroidism (PHPT) is reported to be 94–100% 1 year after surgery, but recent data suggest recurrence in 4% of the patients 1–5 years post-operatively. The aim of our study was to establish the cure rate and its maintenance in the long-term after parathyroidectomy (PTx) in patients with sporadic PHPT.DesignEvaluation of recurrence in patients with sporadic hyperparathyroidism who underwent PTx 1–24 years prior to the study.Patients and methodsWe identified 111 patients who underwent initial PTx between 1984 and 2008, and had no MEN-1, MEN-2, or CaR mutation; parathyroid carcinoma; a history of lithium use; or renal failure. Thirty-eight patients were lost to follow-up or were unwilling or unable to participate in the study. Cure was defined as maintenance of normal serum calcium and parathyroid hormone concentrations 6 months after PTx.ResultsCure was achieved in 68 of 73 patients studied (93%) and was sustained in all for 6±5 years.ConclusionThe cure rate of sporadic PHPT after initial surgery is 93%. When cure is achieved, this is sustained in 100% of the patients for up to 24 years post-operatively. Our data suggest that closer early follow-up is advocated in all patients undergoing PTx to definitively establish cure and to provide a safety net for those with residual gland pathology. The data do not support the need for long-term follow-up when cure is established 6 months after PTx.

Serum Pth

Normocalcemic primary hyperparathyroidism (NPHPT) is a condition characterized by elevation of the parathyroid hormone (PTH) in the presence of normal serum calcium and the absence of secondary causes. The case described illustrates the long-term follow-up of a postmenopausal woman with NPHPT patient who progressed with multiple adenomas. This case reports a 77-year-old female who has chronic generalized pain and osteoporosis. Her initial serum PTH was 105 pg/mL, with total serum calcium of 9.6 mg/dL, albumin 4.79 g/dL, phosphorus 2.8 mg/dL, and 25OHD after supplementation was 34.6 ng/mL. The bone densitometry (BMD) results were as follows: lumbar spine: T-score -3.0, femoral neck: T-score -2.6 and distal radius: -4.2. Other causes of secondary hyperparathyroidism were ruled out and cervical ultrasound and Tc-99-Sestamibi scan were negative. She used oral alendronate and three infusions of zoledronic acid for treatment of osteoporosis. In the 10th year of follow-up, after successive negative cervical imaging, ultrasound showed a nodule suggestive of an enlarged right inferior parathyroid gland. PTH levels in fluid which was obtained during fine-needle aspiration (FNA) were over 5,000 pg/mL and a Sestamibi scan was negative. The patient underwent parathyroidectomy, and a histological examination confirmed parathyroid adenoma. Post-operatively serum PTH remained elevated in the presence of normal serum calcium levels. A follow-up cervical ultrasound showed a new solid nodule suggestive of an enlarged right superior parathyroid gland. PTH levels in the aspiration fluid were remarkably high. A second parathyroidectomy was performed, with the excision of a histologically confirmed parathyroid adenoma. In conclusion, this is an unusual presentation of NPHPT and highlights the long-term complications.

Introduction: Moyamoya patients under two years of age represent a therapeutic challenge because of their frequent neurologic instability and concomitant anesthetic risks. We report our experience with pial synangiosis revascularization in this population. Methods: We reviewed the clinical and radiographic records of all patients with moyamoya syndrome in a consecutive series of patients under 2 years of age, who underwent cerebral revascularization surgery using pial synangiosis at a single institution. Results: During a 12-year period (1994-2005), thirty-four procedures (15 bilateral, 4 unilateral) were performed in 19 patients under two years of age (out of a total of 456 procedures in 240 patients). Eighteen of these patients presented with either stroke or TIA. Average age at first surgery was 1.4 years (range 6 months to 1.9 years). Unanticipated staged operations occurred in three patients, two due to persistent EEG changes during the initial surgery and one due to brain swelling during the procedure requiring ventriculostomy. There were two perioperative strokes; both patients had post-operative seizures but made clinical recoveries. The average follow-up was 7 years (range 1-14). In long term follow-up, 13 patients (68%) were clinically independent for their age, with 8 (42%) having no significant deficit. Late complications included subdural hygroma evacuation (1), additional revascularization procedures years later for frontal lobe ischemia (2), late infarction (1) and asymptomatic ischemic change on routine follow-up MRI studies (1). All patients who had both pre and post-operative angiography demonstrated progression of disease. Conclusions: Despite the challenges inherent to this population, the majority of children with moyamoya under 2 years of age have a good long-term prognosis. Our data support the use of pial synangiosis as a safe, effective and durable method for treatment of moyamoya for most children in this potentially high-risk population.

Familial Hyperparathyroidism

Isolated familial hyperparathyroidism (FHPT) not associated with multiple endocrine neoplasia is a rare and aggressive form of primary hyperparathyroidism. The traditional management of FHPT is a bilateral neck exploration with an increased rate of multigland hyperplasia, supernumerary glands, and recurrence. A prospective database was queried, which included 1383 consecutive parathyroidectomies between 1992 and 2008, and 28 patients with FHPT were identified. Patient demographics, pathology, intraoperative parathyroid hormone (IOPTH) kinetics, recurrence patterns, and accuracy of localization studies were analyzed. Twenty-one patients underwent bilateral neck explorations as an initial surgery, and seven patients had nine unilateral neck explorations for recurrent hyperparathyroidism. Overall cure rate was 89.2 per cent with a mean follow-up of 2.9 years (range: 6 months to 9.2 years); 64.3 per cent of patients had multigland disease. IOPTH helped identify supernumerary glands in three (12.5%) patients and accurately lateralized recurrent disease in eight of nine surgeries (88.8%). Tc-99m-Sestamibi failed to identify multigland disease in 11 patients (52.3%). FHPT has a greater prevalence of multigland disease, decreased utility of sestamibi scanning, and a higher recurrence rate than sporadic primary hyperparathyroidism. In FHPT, IOPTH is a useful adjunct in identifying additional tumors and in select cases may play a role in tumor localization.

BackgroundTransvenous embolization of brain arteriovenous malformations (AVMs) can be curative. We aimed to evaluate the cure rate and safety of the transvenous retrograde pressure cooker technique (RPCT) using coils and n-butyl-2-cyanoacrylate as a venous plug.MethodsAll AVM patients treated via transvenous embolization between December 2004 and February 2017 in a single center were extracted from our database. Inclusion criteria were: inability to achieve transarterial cure alone; AVM < 3 cm; and single main draining vein. Outcome measures were immediate and 90 days' angiographic AVM occlusion rate, and morbidity and mortality at 30 days and 12 months, according to the modified Rankin Scale (mRS) score.ResultsFifty-one patients (20 women; median age 47 years) were included. A majority (71%) were high grade (3 to 5 in the Spetzler–Martin classification). AVMs were deeply seated in 30 (59%) and cortical in 21 patients (41%). Thirty-three patients were previously embolized transarterially (65%). All patients but one were cured within a single session with the RPCT (96%). Cure was confirmed on follow-up digital subtraction angiography at 3 months in 82% of patients. Three patients experienced intracranial hemorrhage (6%), one requiring surgical evacuation. There were no deaths. One treatment-related major permanent deficit was observed (2.0%). Mean mRS before treatment, at 30 days, and 12 months after RPCT was 1.5, 1.5, and 1.3, respectively.ConclusionsThe retrograde pressure cooker technique can be curative in carefully selected high-grade AVMs. Long-term follow-up and prospective studies are needed to confirm our results.

Tight Filum Terminale

Abstract BACKGROUND: Section of a tight filum terminale is a minimally invasive procedure compared with cord untethering procedures used for more complex spinal abnormalities. Anecdotal evidence suggests, however, that the risk of symptomatic retethering resulting from scarring might be higher than previously thought. OBJECTIVE: To determine the frequency of symptomatic retethering after section of a tight filum terminale and to explore possible risk factors. METHODS: We reviewed databases at 2 pediatric neurosurgery centers for all patients who had surgery for a suspected tight filum terminale between January 1982 and June 2009. RESULTS: We identified 152 patients. The median length of follow-up was 78 months. Thirteen patients (8.6%) went on to retether symptomatically at a median time of 23.4 months after the initial procedure. Eight had early retethering (within 2 years) and 5 had late retethering (after 7 years). Compared with late retetherers, early retetherers were older at initial surgery (median, 9.4 vs 0.9 years of age), had a higher level of the conus (median, L1/L2 vs L3/L4), had more arachnoiditis after initial surgery, and required more repeat untethering procedures. Late retetherers were younger at initial surgery than those who did not retether (median, 0.9 vs 4.5 years of age). CONCLUSION: Symptomatic retethering is not uncommon after a simple filum snip, and long-term follow-up is warranted. Two distinct patterns of retethering were observed. Arachnoiditis caused by infection or a cerebrospinal fluid fistula may predispose to early retethering, whereas early surgery for prevention of tethered cord symptoms may predispose to late retethering.

✓ The authors report the results of a long-term follow-up study of the effects of the physiologically defined selective VIM (nucleus ventralis intermedius)-thalamotomy on tremor of Parkinson's disease in 27 patients and essential tremor in 16 patients. The follow-up period ranged from 3.25 to 10 years (mean 6.58 years). In 43 patients a total of 50 operations (including four bilateral operations and three reoperations) were carried out. The early (2 to 4 weeks after surgery) and late effects on the tremors were determined clinically and electromyographically. Fourteen parkinsonian cases were treated with minimal lesions (about 40 cu mm). Their late results were very similar to the early results: in 10, the tremors were completely abolished, three had a slight residual tremor, and one underwent reoperation 3 months after the first surgery. Eleven essential tremor cases were treated with minimal lesions. Six of these tremors were completely abolished, four patients had slight residual tremors, and one patient with a recurrence underwent reoperation 2 years after the initial surgery. In these 23 successful operations with minimal lesions (excluding two cases with reoperation), the tremor was abolished without discernible long-lasting side effects. The other 23 operations on 16 patients with Parkinson's disease (including one reoperation) and on seven with essential tremor (one of whom also had a minimal lesion on the other side) involved relatively large lesions. In this group, the surgery was successful in almost every case. It was concluded that radiographically and physiologically monitored selective VIM-thalamotomy for parkinsonian and essential tremor is effective even when lesioning is minimal. Moreover, the beneficial effect is maintained over a long period of time.
