ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Primary spinal extraosseous Ewing sarcoma (ES) is a rare mesenchymal tumor characterized by high malignancy, occurring in a few patients with ES. The occurrence of this tumor in the intradural extramedullary spinal region is infrequent. This systematic review examines primary extraosseous intradural extramedullary ES in the cervical region to provide specific outcomes and evaluate the role of adjuvant chemoradiation in overall prognosis. A systematic review was conducted to identify all cervical primary extraosseous intradural extramedullary ES reported in the literature. The search included the databases of PubMed, Google Scholar, Medline, Embase, and Scopus from inception to June 2021. Inclusion criteria include a reported death outcome or a minimum one-year follow-up. Our search retrieved 21 articles that involved the cervical spine, but only 11 cases met the inclusion criteria. Of the nine patients who demonstrated disease progression, six experienced local failure, two had distant craniospinal axis failure, and one had systemic metastases. Five patients died of the disease at a median of 11 months after diagnosis. Our analysis showed a one-, two-, and five-year progression-free survival (PFS) of 36.4%, 36.4%, and 12.1%, respectively. The one-, two-, and five-year overall survival rates were 72.7%, 62.3%, and 46.8%, respectively. Three of the five (60%) patients who died received craniospinal radiotherapy. Of the six patients who survived, two received craniospinal radiotherapy (33%), and one received whole spine radiotherapy (17%). This review showed that patients with cervical primary extraosseous intradural extramedullary ES had poor progression-free survival and overall survival rates. The addition of adjunct craniospinal radiotherapy did not improve the prognosis of these patients.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Epidermoid cysts of the spinal cord may rupture, resulting in keratin dissemination in the subarachnoid space, in the ventricles, and along the central canal of the spinal cord causing meningitis, myelopathic changes, or hydrocephalus. CASE DESCRIPTION: A 53-year-old woman with no past medical history presented with a 2-week history of headache located in the occipital region associated with neck pain. Brain magnetic resonance imaging demonstrated multiple fat droplets scattered throughout the subarachnoid and intraventricular spaces with significant edema of the right posterior temporoparietal lobes with trapping of the right temporal horn of the lateral ventricle and atrium. An intracranial lesion could not be observed in the study. The spinal region was suspected as the possible culprit, and spinal imaging showed a large cystic lesion at the level of the conus medullaris. The patient underwent neuronavigation endoscopic exploration of the right lateral ventricle with flushing of the keratin particles followed by a posterior lumbar decompression with resection of the epidermoid cyst. Pathology was consistent with an epidermoid cyst. Successful recovery with improvement in symptoms was quickly observed. CONCLUSIONS: When an epidermoid cyst is suspected but no intracranial lesion is found, the intraspinal area should be studied. Rupture of a spinal epidermoid cyst may cause meningitis and inflammation producing obstructive hydrocephalus. We present this rare entity and describe the diagnostic and surgical techniques used.
