    Extremely rare cause of ventriculo-peritoneal (V-P) shunt dysfunction: Spontaneous peritoneal catheter knotting; [Ventrikülo-peritoneal(V-P) şant disfonksiyonun nadir sebebi: Spontan peritoneal katater düǧümlenmesi]
    (Ege University Press, 2014) Yaldiz C.; Kurtuluş Duransoy Y.; Mete M.; Ünlü Ünsal U.; Selçuki M.
    Shunt application is one of the most common treatment method for hydrocephalus. Many complications have been reported in literature for ventricular and peritoneal catheters and shunt valve. Spontaneous knotting of peritoneal catheter is an extremely rare condition. Mechanism of knotting is still unclear and peristaltism, elasticity of shunt materials, intraabdominal density, length of the peritoneal catheter and surgical technique may be responsible factors. In this paper, we presented a peritoneal catheter knotting resulted in shunt dysfunction in an 8-year-old girl. During surgery, we removed the peritoneal catheter, untied the knot and placed in the peritoneum again.

    Kyphectomy in neonates with meningomyelocele
    (Springer Verlag, 2019) Özdemir N.; Özdemir S.A.; Özer E.A.
    Purpose: Kyphosis is the most severe spinal deformity associated with meningomyelocele (MMC) and is seen in approximately 15% of neonates. Our purpose is to present our clinical experience, to discuss the technique and deformity correction in kyphectomy in neonates with MMC, and to assess its long-term outcomes. Method: In this prospective study, the authors reviewed eight cases submitted to surgery between 2013 and 2015. We evaluated clinical characteristics that were analyzed, as were the operative technique employed, and angle range of the kyphosis deformity postcorrection follow-up. Results: Neonatal kyphectomy was performed of six females and two males. The mean birth weight was 2780 g, and the mean age at the time of surgery was 5.6 days. There were S-shaped type deformity in lumbar region in all neonates. In the correction of the kyphotic deformity, a total vertebrae were removed from four patient, whereas a partial vertebrectomy was done in four. The mean operative time was 116 min. No patients did not require the blood transfusion. There were no serious complications, and wound closure was successful in all patients. The mean follow-up period was 4 years and 3 months (range 36–61 months), except one patient who died 1 week after discharge. The mean preoperative kyphosis of 75.6° (range, 50°-90°) improved at last follow-up to 35° (range 15°–55°). All patients had surgical procedures for hydrocephalus. Three patients had surgery for Chiari type II malformation. The mean hospital stay was 27.7 days. Conclusion: Kyphectomy performed at the time of dural sac closure in the neonate is a safe procedure with excellent correction. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.

    Constipation as a Rare Cause of Ventriculoperitoneal Shunt Dysfunction: A Case Report
    (Georg Thieme Verlag, 2020) Mete M.; Selçuki M.
    Ventriculoperitoneal shunt (VPS) insertion is a common neurosurgical procedure for the treatment of hydrocephalus. Constipation can play an important role in shunt failure either by mechanically blocking drainage from the peritoneal end of the VPS catheter or by increasing intra-abdominal pressure. The present report describes a 2-year-old boy with shunt-dependent hydrocephalus who presented with signs of shunt dysfunction. Medical history with detailed physical examination determined the constipation. Before shunt revision, a pediatric fleet enema was administered to possibly relieve the constipation and he had good evacuation of the bowel contents. Following the enema, his continuous crying resolved and ultimately disappeared within a few hours. Brain computed tomography scans performed 4 days later showed a reduction in ventricular size.

    Two challenging cases of pituicytoma
    (Springer Science and Business Media Deutschland GmbH, 2021) Ozisik H.; Yurekli B.S.; Simsir I.Y.; Ertan Y.; Eraslan C.; Ozdemir N.; Ozgiray E.; Saygili F.
    Introduction: Pituicytoma is a rare tumor of the pituitary gland derived from neurohypophyseal pituicytes. Case 1: A 58-year-old female presented with decreased vision; she was admitted to the neurosurgery department of Ege University after the detection of a pituitary macroadenoma. Magnetic resonance imaging (MRI) showed a 28 * 18 * 17-mm suprasellar mass, and laboratory tests revealed hypopituitarism. Hydrocortisone and L-thyroxine treatment were initiated, and the patient underwent resection through the endoscopic endonasal approach (EEA). The histopathological examination revealed a pituicytoma. The recurrence of tumor was detected during the 1-year follow-up, and the patient is awaiting surgery. Case 2: A 70-year-old woman presented with visual changes; she had a past medical history of hypophyseal macroadenoma and pituicytoma resected through an EEA in 2012 and 2017, respectively. During follow-up, 2 years after the second surgery, MRI showed progression of the pituicytoma then measuring 38 × 23 × 22 mm; it had invaded the cavernous sinus and was causing hydrocephaly and panhypopituitarism. The patient underwent the third resection through the transcranial approach in order to minimize bleeding. After this surgery, the patient developed diabetes insipidus and underwent treatment with desmopressin. Histopathological examination revealed a pituicytoma. At 6-month follow-up, imaging showed a sellar suprasellar mass 37 × 22 × 24 mm invading the cavernous sinus, indicative of recurrence. In the postoperative period, the patient applied to the department of radiation oncology to have fractionated radiotherapy. Discussion: Pituicytomas are known to be low-grade tumors; because of their rarity, they are a real challenge. These patients should be followed up closely. © 2021, Hellenic Endocrine Society.
