RESUMO
INTRODUCTION: Many pathologies require normal-sized ventricle cannulation, which may be technically challenging even with neuronavigation guidance. This study presents a series of ventricular cannulation of normal-sized ventricles using intraoperative ultrasound (iUS) guidance and the outcomes of patients treated by this technique, for the first time. METHODS: The study included patients who underwent ultrasound-guided ventricular cannulation of normal-sized ventricles (either ventriculoperitoneal (VP) shunting or Ommaya reservoir) between January 2020 and June 2022. All patients underwent iUS-guided ventricular cannulation from the right Kocher's point. The inclusion criteria for normal-sized ventricles were as follows: (1) Evans index <30%, and (2) widest third ventricle diameter <6mm. Medical records and pre-, intra- and post-operative imaging were retrospectively analyzed. RESULTS: Nine of the 18 included patients underwent VP shunt placement; 6 had idiopathic intracranial hypertension (IIH), 2 had resistant cerebrospinal fluid fistula following posterior fossa surgery, and 1 had iatrogenic intracranial pressure elevation following foramen magnum decompression. Nine patients underwent Ommaya reservoir implantation, 6 of whom had breast carcinoma and leptomeningeal metastases and 3 hematologic disease and leptomeningeal infiltration. All catheter tip positions were achieved in a single attempt, and none were placed suboptimally. Mean follow-up was 10 months. One IIH patient (5.5%) had early shunt infection which necessitated shunt removal. CONCLUSION: iUS is a simple and safe method for accurate cannulation of normal-sized ventricles. It provides an effective real-time guidance option for challenging punctures.

PURPOSE: The aim of this study was to analyze epidemiologic data of patients with head injuries (HI) who were admitted to the Trauma and Emergency Surgery Department. METHODS: The hospital records of 497 patients with HI who were admitted to the Trauma and Emergency Surgery Department from January 1, 2014, through 31 December, 2014, were analyzed retrospectively. RESULTS: The male-to-female ratio was 2:1, and the mean age was 16.3 years. The rates of patients with mild, moderate, and severe HI were 93, 3, and 4 %, respectively. The most common cause of trauma was falls. Linear fractures were the most common radiologic diagnoses with 242 cases (49 %). Of the patients admitted to hospital, 22 % presented 4 h after the trauma had occurred. Mortality rate due to HI was 3 % (15 patients). Outcome was associated with admission Glasgow Coma Scale and presence of additional trauma. CONCLUSIONS: The number of traffic accidents and assaults were considerably higher in the young adult population compared with the other age groups. Traffic accidents accounted for 46.6 % of the mortality rate. Mortality in HI patients mostly arises from preventable conditions, and the young adult population seems to be the most affected group. HI should be considered as a public health issue, and prevention of HI should be the primary goal.
