For patients with COVID-19, a characteristic excessive long-term activation of the complement system was revealed, which is manifested by an increase in the level of C3 and C4 components (in the acute period of Covid-19, the level of the C3 compon

Abstract:

AbstractAcute limb ischemia (ALI) is a vascular emergency associated with a high risk for limb loss and death. Most cases result from in situ thrombosis in patients with preexisting peripheral arterial disease or those who have undergone vascular procedures including stenting and bypass grafts. The other common source is cardioembolic. The incidence has decreased in recent times due to better anticoagulation strategies. Patients with suspected ALI should be evaluated promptly by a vascular specialist and consideration should be given for transfer to a higher level of care if such expertise is

Abstract:

Introduction. Acute cerebrovascular accident is recognized as the leading pathology in the structure of cerebrovascular diseases (CVD). Annually 6 million cases of CVD are registered in the world. Fatal outcomes from this pathology in Russia occur 1.5–2 times more often than in developed countries. According to the All-Russian Center for Preventive Medicine, 25% of males and 39% of females die from CVD. The incidence of CVD in Russia ranges from 460 to 560 cases per 100 thousand people. This pathology may be caused by carotid artery stenosis resulting from atherosclerotic vascular lesions and

Abstract:

Acute vascular injury that leads to vascular inflammation is a common finding in the preclinical toxicity testing of drugs in rats and dogs. However, the relevance of this finding for risk to humans is unclear. Concern about the safety of these drugs is heightened by the current lack of noninvasive clinical methods to predict the onset of vascular damage in animals or humans. Determining the relevance of this poorly understood preclinical outcome for humans requires a better understanding of the molecular mechanisms of injury in addition to the development of sensitive and specific leading bio

Acute vertigo or dizziness that is accompanied by a sudden sensorineural hearing loss (SSNHL) often poses a diagnostic challenge. While a combined audiovestibular deficit makes an inner ear pathology most likely, this does not necessarily exclude a vascular pathology that may be a harbinger of future sinister events. This is especially true for strokes within the territory of the anterior inferior cerebellar artery (AICA), because the labyrinth receives its vascular supply most often by branches of the AICA.

During the late acute to subacute stages, the mucosa also tends to show a marked increase in numbers of ciliated and secretory epithelial cells. As the inflammatory process ent

Abstract:

Upper extremity acute limb ischemia (ALI) is a limb-threatening and potentially lethal pathology that is most commonly caused by vascular embolization. Outcomes of limb ischemia are time-sensitive due to the correlation between a longer time from symptom onset to intervention with a vastly higher risk of amputation. In this report, point of care ultrasound (POCUS) was utilized to rapidly diagnose a patient with a proximal right brachial artery embolic occlusion, prompting expedited surgical consultation and successful embolectomy. POCUS can provide a focused vascular examination of the limbs t

Abstract:

SummaryMacrophage migration inhibitory factor (MIF) is a pleiotropic cytokine with chemokine-like functions. MIF is a critical mediator of the host immune and inflammatory response. Dysregulated MIF expression has been demonstrated to contribute to various acute and chronic inflammatory conditions as well as cancer development. More recently, MIF has been identified as an important pro-atherogenic factor. Its blockade could even aid plaque regression in advanced atherosclerosis. Promotion of atherogenic leukocyte recruitment processes has been recognised as a major underlying mechanism of MIF

Respiratory changes caused by obstructive sleep apnea (OSA) syndrome increase the risk of ocular vascular diseases. Hypoxia, hypercapnia, endothelial dysfunction associated with OSA syndrome, promote local impairment of fibrinolysis, cause hypercoagulation and vasospasm, creating conditions for retinal vein occlusions as well as for those of posterior ciliary arteries. 91,5 % patients with retinal vein occlusions and 75 % patients with nonarteritic anterior ischemic optic neuropathy have moderate-to-severe OSA.

The following features of the ischaemic and postischaemic brain are the focus of interest: Development of acidosis, edema formation, calcium overload glutamate excitotoxicity, free radical formation and nitric oxide overproduction. The brain is critically dependent on its blood flow for a continuous supply of oxygen and glucose. Energy depletion has fundamental importance in the genesis of subsequent injurious events. Loss of ATP rapidly leads to a massive calcium influx and release of calcium from intracellular compartments. Extracellular concentrations of glutamate are markedly elevated in i

The main processes that characterize the post-COVID syndrome are analyzed as a version of the “prolonged” pathology of acute COVID-19. Considering the variety of manifestations of post-covid pathology, the main blocks of systemic, cellular and molecular dysregulations are distinguished. As the main reasons, the following are considered: the consequences of systemic and organ damage in the acute phase of COVID-19, the persistent activity of “hidden” pathogens and the altered status of the patient’s protective immune systems. Long-term pathology, as a multisystem syndrome, reflects disturbances

Abstract:

Arterial dissection is a well-recognized pathology often seen in Vascular Surgery offices and Emergency Departments alike; however, visceral arterial dissection is an extremely rare, small subset of this entity. With that, an isolated celiac artery dissection as presented within this report is an exceptionally unique pathology that has scarcely been reported, and due to this, management guidelines are undefined. Given the viscera supplied by the celiac artery, many intra-abdominal structures are at risk for ischemia when damage to the celiac artery occurs, potentially witnessed by this report.

In surviving animals, symptoms were reversible even if treatment was continued.

Abstract:

Coronary artery aneurysms are rare complications following stenting and were reported with drug-eluting as well as bare metal stents. They can be asymptomatic or present as acute coronary syndromes and usually detected during coronary angiography. The mechanisms responsible can be vascular trauma, hypersensitivity to drug, polymer, or metal. Rarely, it can be due to acute bacterial infections resulting in mycotic aneurysms. Management depends on symptoms, presentation, and underlying pathology and has to be tailored on a case-to-case basis.

Introduction Proper placental gross examination requires weighing the placental disc trimmed of fetal membranes and the umbilical cord. However, untrimmed placental weights are often reported, both in cases submitted for consultation and in publications. Thus, determining the contribution of membranes and cords to untrimmed placental weights would be helpful in estimating the true trimmed weight of placentas. We sought to report the average weights of membranes and cord in term placentas and to correlate these weights with common placental pathologies. Methods A total of 500 consecutive placen
