“…В настоящем исследовании мы пришли к подобному заключению: НЩА имеет больший просвет по сравнению с ВЩА (p=0,032, t-критерий) при сопоставимой длине сосудов (p=0,653, t-критерий). Распространенность в общей популяции атеросклероза каротидных артерий составляет 55% у мужчин и 46% у женщин [25]. Сужение просвета сонных артерий на 25% выявлено у 28% мужчин в возрасте 55-64 лет [26], тогда как поражение атеросклерозом подключичной артерии происходит реже [27].…”

BACKGROUND. Current trends of «fast track surgery» give rise to development of new safe techniques of the thyroid and parathyroid surgery, the purpose of which is to minimize the level of postoperative complications, such as vocal cord palsy, hypoparathyroidism, bleeding. In this regard, it is important for the endocrine surgeon to save «dry operating field», which contributes to the clear visualization of such «thin» structures as the recurrent laryngeal nerve, the external branch of the superior laryngeal nerve and the parathyroid glands. Therefore, the key issue of this surgery is to understand the anatomical and topographic features of the blood supply to the internal neck organs (a complex of neck organs consisting of the thyroid and parathyroid glands, larynx, trachea, esophagus).AIM. To determine the main sources of arterial blood supply of the internal neck organs and their anatomical, topographic features.MATERIALS AND METHODS. The computed tomography protocols of cervical branches of brachiocephalic arteries were analysed in the study. The thickness of the reconstructed sections in the axial, frontal and sagittal planes was 0.35±0.05 mm. The fact of blood supply was confirmed by the anatomical close of the arterial structure to the internal organ and the presence of intramural arterial branches.RESULTS. The course of all cervical branches of the subclavian and common carotid artery was traced among 42 patients. It is noted, that only the inferior, superior thyroid arteries and thyroid ima artery supply internal neck organs with the blood. At the same time, the superior thyroid artery was visualized in all angiograms. However, the inferior thyroid artery was absent in 2.4% of cases. The thyroid ima artery was rarely detected (in 4.8% of patients). In 73.2% of cases, the inferior thyroid artery was detected high at the upper third level of the thyroid lobe and then had a descending course. In 23.2% of cases, the artery was formed at the middle third level of the thyroid lobe and was directed horizontally to the gland. Only in 3.6% of cases, the ascending course was determined in the vessel. The inferior thyroid artery was located on the posterior surface of the thyroid lobe, where it formed glandular branches. On the contrary, the branches of the superior thyroid artery were located mainly along the anterolateral surface of the thyroid gland. The average thickness of the inferior thyroid artery was 2.1±0.5 mm, and the superior thyroid artery was 1.6± 0.7 mm.CONCLUSION. According to the study, arterial blood supply to the internal neck organs is provided mainly by the inferior and superior thyroid arteries. At the same time, the trunk of the inferior thyroid artery is larger than the superior thyroid artery (p=0.032). The inferior thyroid artery forms branches along the posterior surface of the thyroid lobe and from a topographic point of view it is the main source of blood supply to the parathyroid glands. In most cases, the inferior thyroid artery has a descending course, is directed along the posterior surface of the thyroid gland and forms an X-shaped intersection with the recurrent laryngeal nerve.

“…The reported accuracy of TIA diagnosis among non-neurologists is quite variable, with overall agreement rates varying between 39 and 67%. [18][19][20][21] In a recent study of 100 hospitalized patients who had a presumptive ED-based diagnosis of TIA, a retrospective chart review by two stroke neurologists found that 60% were misdiagnosed. 22 However, such results should not be interpreted as necessarily reflecting on the clinical skills of neurologists and ED physicians; rather, these data are a reflection of the fact that more complete and definitive diagnostic information (e.g.…”

More than 700,000 acute strokes 1 and 300,000 transient ischemic attacks (TIAs) 2,3 occur annually in the US. It is estimated that between 15 and 26% of acute stroke cases have a prior history of TIA. 4 TIAs are important because they are associated with high short-term risk for both stroke and cardiac events. In a widely quoted emergency department (ED) study of over 1,700 TIA cases from California, the three-month stroke risk was found to be 10.5%. 5 A recent meta-analysis of 11 TIA cohort studies found that the summary estimate for the 90-day stroke risk was 9.2%-very similar to the Californian study. 6 This meta-analysis also confirmed that most of this stroke risk occurs in the first few days after the TIA event; the risk for stroke was 3.5% at two days and 8.0% at 30 days. 6 Similar findings were found in another recent meta-analysis of 18 cohort studies, which estimated that the seven-day risk for stroke was 5.2%. 7 Patients with TIA are also at high risk for other cardiovascular events. In a meta-analysis of 39 cohort studies, the annual risk for myocardial infarction and non-stroke vascular death following TIA was 2.2 and 2.1%, respectively. 8 These studies, which serve to illustrate

Background Whether a relationship between atherosclerosis and subsequent venous thromboembolism (VTE) exists is controversial. Objective To investigate the association between carotid atherosclerosis and VTE by using repeated measurements of intima media thickness (IMT) and total plaque area (TPA) in participants recruited from the general population. Methods Participants were recruited from the fourth (1994-1995), fifth (2001-2002) and sixth (2007-2008) surveys of the Tromsø Study. In total, 10 426 participants attended, for whom measurements of carotid IMT and TPA and potential confounders were updated at each available survey. Time-varying Cox regression models were used to calculate hazard ratios (HRs) of VTE across various levels of IMT and TPA adjusted for age, sex, and body mass index. Results There were 368 incident VTE events during a median follow-up of 10.8 years. Participants with increasing IMT were, on average, older and had a less favorable cardiovascular risk profile. There was no association between tertiles of increasing TPA and the risk of VTE in the time-varying model, and increasing IMT was not associated with an increased risk of VTE (HR 0.96, 95% confidence interval [CI] 0.86-1.07). Neither plaque formation nor plaque progression was associated with the risk of VTE (respectively: HR 1.00, 95% CI 0.98-1.02; and HR 0.96, 95% CI 0.84-1.11). Conclusion Carotid IMT and TPA were not associated with an increased risk of VTE in time-varying analyses. Furthermore, there was no association between plaque initiation or plaque progression and subsequent VTE.
