RESUMO
Background: Due to the SARS-CoV-2 virus pandemic and its rapid spread worldwide, an early and effective detection strategy was the nasopharyngeal reverse transcription polymerase swab tests, a procedure still performed today. A relatively safe procedure when done correctly, however, one of the rare complications reported in the literature includes a cerebrospinal fluid (CSF) leak. Case Description: A 69-year-old female patient presented to the emergency department with clear fluid rhinorrhea, clinically diagnosed with a CSF fistula after a SARS-CoV-2 nasopharyngeal swab. Resulting computed tomography and magnetic resonance images did not report any abnormalities; however, persistence of clear fluid rhinorrhea obligated pharmacological treatment without resolution, requiring insertion of a lumbar catheter to achieve clinical resolution. Conclusion: It is essential to train staff to correctly administer nasopharyngeal swabs and thus reduce the rate of complications, as well as early recognition of symptoms and signs of CSF fistula.
RESUMO
BACKGROUND: Trends in management of aneurysmal subarachnoid hemorrhage and unruptured intracranial aneurysms among neurosurgeons is very variable and had not been previously described in any Latin American country. This study was conducted to determine the preferences of Colombian neurosurgeons in pharmacologic, surgical, and endovascular management of patients with aneurysmal subarachnoid hemorrhage and unruptured intracranial aneurysms. METHODS: A survey-based descriptive study was performed in a sample of members from the Colombian Association of Neurosurgery. Questions about pharmacologic, surgical, and endovascular management of aneurysmal subarachnoid hemorrhage and unruptured intracranial aneurysm were carried out. We calculated the mean and the standard deviation of the results obtained from the continuous variables. The results of the categorical variables are presented as percentages. RESULTS: The preference of medication with poor clinical evidence, such as magnesium sulfate, aspirin, statins, and anti-fibrinolytics was lower than 10%. The use of intravenous nimodipine and systemic glucocorticoids was as high as 31%. The availability of endovascular therapy was 69%. The indication for treatment of patients with unruptured intracranial aneurysms that required intervention was less than 13.8%. In patients with ruptured or unruptured intracranial aneurysms, coiling was the preferred method for exclusion. CONCLUSIONS: Reported compliance of evidence-based clinical guidelines was similar to that described in developed countries, and even better. However, there is little agreement in treating patients with unruptured intracranial aneurysms. For other issues, the conducts reported by Colombian neurosurgeons are in accordance with the current guidelines.
RESUMO
BACKGROUND: The presentation of moyamoya disease (MMD) as an aneurysmal subarachnoid hemorrhage (SAH) is relatively frequent and in the absence of aneurysms is extremely rare. CASE DESCRIPTION: A 53-year-old male patient suddenly developed severe headache associated with dysarthria and an altered state of consciousness. At the time of admission, he was found drowsy with global aphasia, stiff neck, right hemiparesis and right Babinski's sign. A non-contrast brain computed tomography was performed and a small bleeding in the subarachnoid space over the left frontal and parietal cortex was observed. Four-vessel cerebral angiography showed bilateral stenosis of the internal carotid arteries, with multiple tortuous vessels branching from the anterior and middle cerebral arteries. These abnormal vessels were anastomosing with branches from the posterior cerebral and middle meningeal arteries. With this information, a diagnosis of MMD was made. A three-dimensional reconstruction from digital angiography ruled out aneurysms or vascular malformations. After 4 weeks, another angiography was performed and remained the same as previous one. CONCLUSION: Clinical and radiological characteristics of this case are consistent with previous reports, supporting the theory that non-aneurysmal SAH in MMD is caused by rupture of fragile moyamoya vessels.
