Percutaneous Ventriculoatrial Shunting as a Salvage Method in the Pediatric Hydrocephalus Patients with Peritoneal Problems.

AIM: To evaluate the efficacy of percutaneous ventriculoatrial shunting as a salvage method for pediatric patients with abdominal complications. MATERIAL AND METHODS: Data obtained from 9 patients with ventriculoperitoneal shunt dysfunctions owing to abdominal complications, who underwent ventriculoatrial shunting as salvage treatment at a single institution between January 2019 and September 2021 were retrospectively analyzed. All operations were conducted under the guidance of intraoperative fluoroscopy and ultrasound. RESULTS: The mean age of the enrolled patients was 8.1 ± 1.2 years (2-15 years). Six (67%) patients were male and 3 (33%) were female. The mean number of the patients? ventriculoperitoneal shunt revisions until atrial catheter placement was 7.5 times. The reasons for intraperitoneal catheter failure included peritoneal adhesions in 4 (44.5%) patients, pseudocyst formation in 3 (33.3%), and peritonitis in 2 (22.2%). Seven patients from the study cohort had no problem after ventriculoatrial shunt placement. Only 1 patient had shunt dysfunction related to the ventricular catheter, and ventricular catheter and shunt valve revision was performed 26 months after ventriculoatrial shunt placement. The atrial catheter of the patient was intact. One patient died from the progression of her primary disease (medulloblastoma in the 4 < sup > th < /sup > ventricle), which was unrelated to the ventriculoatrial shunt. CONCLUSION: Percutaneous ventriculoatrial shunting under the guidance of intraoperative fluoroscopy and ultrasound is a safe, effective, and easy alternative in patients with peritoneal complications and a history of multiple operations.

Spine Metastasis of Thymic Carcinoma in a Pediatric Patient: A Case Report and Comprehensive Literature Review.

INTRODUCTION: Thymic carcinoma metastases of the spinal column are very rare, especially in pediatric patients. To our knowledge, this is the first such pediatric case in the literature. CASE PRESENTATION: We report the case of a 14-year-old male patient with T12 and L1 metastases of thymic carcinoma. He had history of thymectomy and intrathoracic tumor resection 7 months previously. The patient's neurological condition deteriorated; therefore, tumor resection and decompression of the spinal canal were performed. He underwent instrumentation and fusion procedures to prevent spinal instability. CONCLUSION: The main purpose of the treatment is gross total resection of the thymic carcinoma. However, adjuvant methods such as radiotherapy and chemotherapy should be added to the treatment protocol in patients who have higher stage diseases or those in whom total tumor resection cannot be achieved.
