Convexity subarachnoid hemorrhage: clinical features and etiology of an Argentinian cohort

Conclusion: Convexity subarachnoid hemorrhage may be related to a wide spectrum of etiologies. In our patients, an increased prevalence of cerebral vein thrombosis was observed. Mortality was low and not related to the bleeding itself.RESUMO A hemorragia subaracn óidea não traumática da convexidade é um subtipo cada vez mais reconhecido de sangramento subaracnóideo. Objetivo: Nosso objetivo foi descrever a etiologia e as características clínicas de uma coorte de pacientes com hemorragia subaracnóidea da convexidade. Métodos: Foram analisados retro spectivamente todos os casos de hemorragia subaracnóidea da convexidade admitidos em nosso hospital entre janeiro de 2012 e abril de 2017. Foram avaliados os aspectos demográficos, características clínicas, investigações complementares, etiologia e mortalidade. Vinte pacientes (65% mulheres) f oram identificados. Média de idade: 53 anos (intervalo, 15-86). Resultados: Sintomas na admissão: dor de cabeça (65%), sintomas sensitivos e/ou motores (50%) e convulsões (35%). Causas mais comuns: trombose venosa cerebral (20%), síndrome de vasoconstrição cerebral reversível (20%) e angiop atia amilóide cerebral (20%). Dois pacientes morreram. Conclusão: A hemorragia subaracnóidea da convexidade pode estar relacionada a um amplo espectro de etiologias. Em nossos p...

This study, for instance, attributes a patient’s waitlist/transplant outcome to the very last dialysis facility the patient was associated with.  In epidemiology speak, this means the causal inference authors are trying to draw between for-profit status and good transplant outcomes is subject to time-varying confounding. As an example, if one is seeking an association between testosterone levels and risk of a heart attack, using the last testosterone level available would be a poor way of doing this study because testosterone levels are known to vary over time. The same applies to dialysis facilities. Patie...

ConclusionPediatric aneurysms are rare, and often present as dissecting thrombosed aneurysms or giant aneurysms. ACA dissecting aneurysms are rare but often occur at a young age, and they easily cause thrombosis, which may occlude the aneurysm and the parent artery, resulting in unknown bleeding sources.It is necessary to suspect rupture of an ACA dissecting aneurysm if there is an ICH and SAH of an unknown source of bleeding where the hematoma is localized near the ACA. Craniotomy can effectively remove the hematoma and identify the bleeding source, and it is more desirable to secure the parent artery to prevent re-rupture.

Introduction: Cerebral vein thrombosis (CVT) is an uncommon cause of stroke and is more likely to affect young adults and children. Women have a three-fold increased risk compared to men, owing to gender specific factors such as oral contraceptive use (OCP), pregnancy, and hormone replacement therapies. The presenting symptoms of CVT are non-specific and include headache, seizure, focal neurological deficits, or coma as the most severe presentation. The rarity and variable symptoms of the disease leads to delayed diagnosis and implementation of treatment. With improved imaging techniques and increased awareness in recent y...

Rationale: Posterior reversible encephalopathy syndrome (PRES) is characterized by clinical and radiological features, including headache, disturbed consciousness, seizures, and cortical blindness associated with findings indicating posterior leukoencephalopathy on imaging studies. Ours is the first case of PRES developing after postpartum hemorrhage and uterine artery embolization. Patient concerns: An 18-year-old patient had postpartum hemorrhage after a normal delivery. She required uterine artery embolization to stop the bleeding; however, she developed PRES 2 hours after the surgery. Diagnoses: Brain compute...

We describe a patient in whom transverse sinus thrombosis preceded intracranial venous hypertension and PNSAH. These findings supported that the source of the subarachnoid hemorrhage is venous in origin. Patient concerns and diagnoses: A 45-year-old right-handed man was admitted to the hospital with a sudden onset of severe headache associated with nausea, vomiting, and mild photophobia for 6 hours. The patient was fully conscious and totally alert. An emergency brain computed tomography (CT) revealed an acute subarachnoid hemorrhage restricted to the perimesencephalic cisterns. CT angiography revealed no evidence of an...

Conclusions:Re-bleeding was seen in 10% of cSAH patients and in the majority of patients occurred early, within 2.5 days. Clinicians should be aware of this potential complication of cSAH.Disclosure: Dr. Harris has nothing to disclose. Dr. Forman has nothing to disclose. Dr. Conners has nothing to disclose. Dr. Garg has received research support from the AHA and RTSC. Dr. John has nothing to disclose. Dr. Lee has nothing to disclose.
