RESUMO

OBJECTIVE: The analysis of morbidity and mortality is fundamental for improving the quality of patient care. The objective of this study was to evaluate the combined medical and surgical morbidity and mortality of neurosurgical patients. METHODS: We performed a daily prospective compilation of morbidities and mortalities during a consecutive 4-month period in all the patients who were 18 years of age or older and had been admitted to the neurosurgery service at the Puerto Rico Medical Center. For each patient, any surgical or medical complication, adverse event, or death within 30 days was included. The patients' comorbidities were analyzed for their influence on mortality. RESULTS: Fifty-seven percent of the patients presented at least 1 complication. The most frequent complications were hypertensive episodes, mechanical ventilation for more than 48 hours, sodium disturbances, and bronchopneumonia. Twenty-one patients died, for an overall 30-day mortality of 8.2%. Mechanical ventilation for more than 48 hours, sodium disturbances, bronchopneumonia, unplanned intubation, acute kidney injury, blood transfusion, shock, urinary tract infection, cardiac arrest, arrhythmia, bacteremia, ventriculitis, sepsis, elevated intracranial pressure, vasospasm, stroke, and hydrocephalus were significant factors for mortality. None of the analyzed patients' comorbidities were significant for mortality or longer length of stay. The type of surgical procedure did not influence the length of stay. CONCLUSION: The mortality and morbidity analysis provided valuable neurosurgical information that may influence future treatment management and corrective recommendations. Indication and judgment errors were significantly associated with mortality. In our study, the patients' comorbidities were not significant for mortality or increased length of stay.

RESUMO

OBJECTIVE: Review the profile of patients with spinal trauma after diving accidents referred to the Puerto Rico Medical Center. This study intended to develop more awareness of the risks of spinal cord injury after diving. METHODS: The patient's records for diving accident cases referred to our center during January 2014 until December 2020 were assessed retrospectively. The cases were evaluated according to sex, age, vertebral level, and neurological deficit. The Puerto Rico Medical Center is the only level 1 trauma center in Puerto Rico; therefore, this study likely included all the cases of diving injury on the island. RESULTS: Sixty five patients with a median age of 29 years were identified consisting primarily of males (94%). The regions affected included the cervical (96%), thoracic (2%), and lumbar (2%) spine. Twenty-seven patients (42%) developed a spinal cord injury secondary to a diving accident. Involvement of the C4, C5, or C6 vertebral level, was significant for the development of a spinal cord injury. Diving accidents occurring at beaches were the most common cause. CONCLUSION: In Puerto Rico, there is a yearly incidence of 9.3 diving accidents causing spinal trauma; these accidents most frequently affect the C6 vertebra. These diving accidents mainly occur in young individuals, predominantly at beaches. Most of our patients were neurologically intact after their diving accident, although 42% sustained a spinal cord injury. This study provided a better understanding of this traumatic event and determined its most affected levels, accident sites, and population involved.

RESUMO

Spinal solitary fibrous tumour (SFT) is an uncommon tumour with few cases reported in the literature. It rarely originates at the craniocervical junction. To our knowledge, only eight cases of spinal SFT located at the craniocervical junction have been reported in the literature. We presented a patient with a craniocervical junction SFT and discussed its clinical presentation, radiological features, pathology, management and outcome. This was the first patient reported in the literature with a recurrent craniocervical junction SFT treated with Gamma Knife radiosurgery. The treatment reduced the tumour volume by more than 85% within 12 months.

RESUMO

BACKGROUND: Surgical site infection (SSI) is a well-documented complication in patients who undergo posterior spine instrumentation with most studies reporting an incidence of 1%-12%. Some studies have documented that a diluted sterile povidone-iodine (PVI) solution can be safely used in posterior spinal fusion surgeries as an antiseptic; in this study, we analyzed its effectiveness in reducing SSI. METHODS: This retrospective study consisted of consecutive patients who underwent elective posterior lumbar instrumentation performed by a single surgeon from 2016 to 2019. In the first 134 patients, wounds were irrigated before arthrodesis and closure with 1 L of 0.9% normal saline solution; in the subsequent 144 patients, wound irrigation was with a solution of 35 mL of sterile 10% PVI. Both groups were analyzed to determine if wound irrigation with sterile PVI solution decreased SSIs. RESULTS: There were 9 (6.7%) SSIs in the 0.9% normal saline solution group versus 1 (0.7%) SSI in the PVI group (P = 0.008). PVI solution had a relative risk for SSI of 0.093 (P = 0.008) and an adjusted odds ratio of 0.113 (P = 0.05). Increased body mass index and posterolateral spine fusion with laminectomy were significant risk factors for SSI (P = 0.04 and P = 0.030, respectively). CONCLUSIONS: Wound irrigation with PVI solution significantly reduced SSI in elective posterior lumbar instrumentation cases. Subgroup analysis provided significant results to recommend use of PVI solution for SSI prevention, particularly in overweight and obese patients. We also recommend its use in patients with risk factors for SSI, such as longer operative time and unintended durotomy.
