“…Our study indicated that from 82 patients with cerebral venous and sinus thrombosis, 62 patients were female and 30 patients were male. In the proportion of male to female ratio, as we expected the rate of females with CVT was higher, which is compatible with previous studies and it is due to OCP usage and disorders increasing hypercoagulability in women such as antiphospholipid antibody syndrome, 6,[14][15][16] although the rate of CVT in male patients is a little higher than some previous studies. 11,17,18 We found that thromboses in venous and sinuses happen more often in summer or spring than in winter and autumn.…”

Background: Cerebral venous and sinus thrombosis (CVT) is the rare type of stroke, which can be fatal or causes significant morbidity. CVT could cause by multiple etiologies and risk factors and could present with many signs and symptoms such as a headache, seizure or altered mental status. The gold standard for diagnosing CVT is magnetic resonance venography (MRV) or computed tomographic venography (CTV), as these modalities are not available in many health centers and the early diagnosis of this disease improves significantly the outcome of treatment, we evaluated the diagnostic values of CT and magnetic resonance imaging (MRI) in CVT patients. Methods: We compiled and investigated the radiological and clinical records of 92 patients with the final diagnosis of CVT; we observed the sign of thrombosis in 74 patients who had either the non-contrast CT or MRI plus MRV. We statistically analyzed the sensitivity, specificity, positive predictive value, negative predictive value, accuracy, the positive and negative likelihood ratio of these modalities. Results: Our results demonstrated that the sensitivity of CT scan is 60.5%, and its specificity is 66.7%. The positive predictive value of CT is 85%, and its negative predictive value is 34%. Our study demonstrated that the accuracy of CT in diagnosing CVT patients is 62%. Besides our results showed that the sensitivity of MRI in diagnosing CVT is 87%, and the specificity of MRI is 76.9%. Hence the positive predictive value of MRI is 94%, and the negative predictive value is 58%, and the accuracy of this modality is 85% Conclusion: In the absence of gold standard modalities, MRI and CT scan have relatively good diagnostic values, besides MRI is more beneficial between the two, moreover we found that CVT is more prevalent among women and in warm seasons.

“…Oral contraceptives can decrease anticoagulant activity and promote a decrease in tissue plasminogen activator inhibitor and are known to be a risk factor for venous thromboembolism [15]. Although we could not find any inherited or secondary thrombophilia in this case, oral contraceptives might have contributed to formation of embolism.…”

Acute arterial occlusion due to left ventricular thrombus of Takotsubo cardiomyopathy in a young adult: a case report

Background: Thromboembolism is a rare complication of Takotsubo cardiomyopathy. Importantly, an acute arterial occlusion needs rapid diagnosis and urgent treatment to help save the patient's life. Here, we report a case of arterial occlusion due to ventricular thrombus of Takotsubo cardiomyopathy. Case presentation: A woman in her 30s, without previous medical history, felt sudden strong pain on her right leg and was diagnosed with right femoral arterial occlusion. An emergency operation was subsequently performed to take out thrombus. The patient's oxygenation deteriorated to 93% of hemoglobin saturation just after extubation and exacerbated in the intensive care unit. Transthoracic echocardiography revealed Takotsubo cardiomyopathy-like left ventricular wall motion abnormalities and left ventricular thrombus. Heparin treatment was immediately started. After 10 days, the thrombus disappeared and the left ventricular wall motion improved and she was discharged from the hospital. Conclusions: The patient's acute arterial occlusion in this case report was mainly caused by thrombus of cardiac origin. We suggest to routinely check echocardiography reports before surgery and perform anesthetic management carefully to better control the patient's blood pressure and heart rhythm.

“…Sinus sagittalis thrombosis is a very rare occlusive disease of cerebral sinuses that can be caused by a variety of factors including infections, oral contraceptives, intracranial hypertension, coagulation disorders or neurosurgical operations (Xu et al, 2017; Miao et al, 2018). It has been shown that pretreatment with RNase1 significantly reduced the sinus occlusion rate, comparable to the effect induced by heparin application in rat sinus venous thrombosis models.…”

The discovery of extracellular RNA (exRNA) has shifted our understanding of the role of RNA in complex cellular functions such as cell-to-cell communication and a variety of pathologies. ExRNAs constitute a heterogenous group of RNAs ranging from small (such as microRNAs) and long non-coding to coding RNAs or ribosomal RNAs. ExRNAs can be liberated from cells in a free form or bound to proteins as well as in association with microvesicles (MVs), exosomes, or apoptotic bodies. Their composition and quantity depend heavily on the cellular or non-cellular component, the origin, and the RNA species being investigated; ribosomal RNA provides the majority of exRNA and miRNAs are predominantly associated with exosomes or MVs. Several studies showed that ribosomal exRNA (rexRNA) constitutes a proinflammatory and prothrombotic alarmin. It is released by various cell types upon inflammatory stimulation and by damaged cells undergoing necrosis or apoptosis and contributes to innate immunity responses. This exRNA has the potential to directly promote the release of cytokines such as tumor necrosis factor factor-α (TNF-α) or interleukin-6 from immune cells, thereby leading to a proinflammatory environment and promoting cardiovascular pathologies. The potential role of exRNA in different pathologies of the central nervous system (CNS) has become of increasing interest in recent years. Although various exRNA species including both ribosomal exRNA as well as miRNAs have been associated with CNS pathologies, their precise roles remain to be further elucidated. In this review, the different entities of exRNA and their postulated roles in CNS pathologies including tumors, vascular pathologies and neuroinflammatory diseases will be discussed. Furthermore, the potential role of exRNAs as diagnostic markers for specific CNS diseases will be outlined, as well as possible treatment strategies addressing exRNA inhibition or interference.
