Moya-Moya disease is a rare progressive chronic cer-ebrovascular disease characterized by a narrowing of the lumen of the intracranial segments of the internal carotid arteries, as well as the initial segments of the anterior and middle cerebral arteries with the devel-opment of a network of small vascular anastomoses. Violations of blood supply due to occlusion lead to the development of ischemic strokes in the correspond-ing pools, and ruptures of vascular anastomoses - to the development of hemorrhagic strokes, causing a variety of neurological disorders. The article presents a clinical case of Moya-Moya disease in a 31-year-old patient. The disease was manifested by acute disorders of cerebral circulation in ischemic and hemorrhagic types. The diagnosis was made in accordance with the diagnostic criteria of the disease based on the data of endovascular cerebral angiography.

Internal Carotid Arteries

Background:Patients with rheumatoid arthritis (RA) are at higher cardiovascular risk (CVR) than the general population due to chronic inflammation. Several factors, both modifiable and non-modifiable, can increase this risk. Intima-media thickness (IMT) was considered as a marker for atherosclerosis.Objectives:This study aimed to identify predictor factors of increasing IMT.Methods:The prospective study was carried out on patients with RA who met the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria. These patients were followed in the rheumatology department of the Kassab Institute. The socio-demographic data, biological and immunological parameters were collected.Framingham’s score quantified the cardiovascular risk at 10-years. Carotid Ultrasonography (US) using a high resolution B mode carotid measured intima-media thickness (IMT) as a subclinical marker of atherosclerosis. Carotid US was performed in the supine position, according to American Society of Echocardiography guidelines. IMT was measured in the left (LCC) and right (RCC) common carotid arteries, the left (LIC) and right (RIC) internal carotid arteries, and the left (LEC) and right (RIC) internal carotid arteries. An increased IMT was defined as ≥0.9 mm.We analyzed data by the SPSS statistical package. A p-value <0.05 was considered significant.Results:Of the 47 patients surveyed, 78.7% were female. The mean age was 52.5 ±11.06 [32-76]. The duration disease was 86.25 ±63 months [5-288] and was erosive in 81.6% of cases. The rheumatoid factor (RF) was positive in 57.8% of patients, and citrullinated antipeptide antibodies (ACPA) were present in 62.2%. Eight patients had a previous CV history (hypertension, diabetes or dyslipidemia) and 16.4% were active smokers. Among women, 43.6% were postmenopausal. ITM was significantly higher in men at LIC (0.037) and LEC (0.025). Older age was associated with increased ITM in LIC (p=0.046; r=0.295), LEC (p=0.05; r=0.412), RCC (p=0.034; r=0.317), and REC (p=0.009; r=0.382). The ITM for LCC, LIC, LEC, RCC, RIC, and REC was higher in postmenopausal women, with no significant difference (p=0.782, p=0.208, p=0.877, r=0.734, p=0.808, p=0.437, respectively).Among the modifiable factors, active smoking was associated with a higher ITM at the REC level (p=0.047). However, weight was not associated with an increased ITM (LCC: p=0.092; LIC: p=0.985; LEC: p=0.952; RCC: p=0.744; RIC: p=0.210; REC: p=0.510). In our study, there was no significant association between DAS28 disease activity or inflammatory marks and ITM (LCC: p=0.784; LIC: p=0.316; LEC: p=0.420; RCC: p=0.784; RIC: p=0.484; REC: p=0.754).Conclusion:In our study, the non-modifiable factors associated with increased ITM were advanced age and male gender. The modifiable factor impacting ITM was primarily active smoking. Surprisingly, disease activity and biological inflammation did not influence ITM.References:[1]S. Gunter and al.

✓ Embolism from an aneurysm is one of the mechanisms involved in the pathogenesis of ischemic symptoms associated with intracranial aneurysms. Four cases are reported in which aneurysms of the internal carotid arteries and middle cerebral arteries were the source of emboli resulting in cerebral infarction. In the treatment of these aneurysms, it is best to clip the neck of the aneurysm with great care to avoid embolism due to extrusion of clot into the distal artery.
