Thoracic endovascular aortic repair (TEVAR) is a widespread minimally invasive procedure prevalently used to treat thoracic aortic pathologies. However, when the left subclavian artery (LSA) is involved in the pathology, a more complex surgical approach is required to guarantee the perfusion of the vertebral and brachial arteries. In fact, coverage of the LSA has been proven to be associated with a higher risk of stroke, spinal cord ischemia, and arm ischemia.Historically, carotid-subclavian bypass or subclavian transposition has been the only treatment options to restore the perfusion of the LSA...

Topographical anatomy and detailed measurements of the glandula thyroidea (thyroid gland) and the glandula parathyroidea (parathyroid gland) were determined in rats, with significant differences identified between the sexes. In the rats (N = 10 male, 10 female), the glandula thyroidea were positioned at the level of the C1 and C2 vertebrae. One glandula parathyroidea was present in each glandula thyroidea lobe, localized in the cranial part of the lateral lobes in 60% of the animals. There was no glandula thyroidea left lobe in one female and no isthmus in two females...

The aberrant right subclavian artery has an incidence of 0.5-1% in the population, generally with retroesophageal location. It can lead to the formation of an arterio-esophageal fistula in patients with predisposing risk factors due to devices placed in esophageal or tracheal position, as it is particularly susceptible to extrinsic compression and pressure necrosis. We present the case of a patient with a postsurgical tracheoesophageal fistula, who developed massive bleeding due to an arterioesophageal fistula secondary to an unknown aberrant right subclavian artery...

OBJECTIVE: The goal of our research was to determine the impact of clinical nutrition in the form of home parenteral nutrition (HPN) in patients with nutritional disorders, most often caused by diseases of the digestive tract, with the risk of developing malnutrition. PATIENTS AND METHODS: We retrospectively evaluated 39 patients from the Gastroenterology Clinic and the Home Parenteral Nutrition Center of the University Hospital Bratislava, whose nutritional status was evaluated based on the determination of the body mass index (BMI), the completed nutritional risk screening (NRS) questionnaire and the determination of performance status...

The lymphatic system of the heart is directly involved in the spread and development of many pathological processes in animals, particularly neoplasias of various etiologies. Precise knowledge of the lymphatic outflow pathways from the heart gives access to close study of pathogenesis. It allows to actively influence the elimination of the process through preventive and therapeutic measures. In this regard, our study aims to explore the anatomical and topographic features of the lymphatic outflow of the heart in an Anglo-Nubian goat...

BACKGROUND: The detailed morphology and topography of the sympathetic cardiac nerves (SCNs) and ganglia with their surrounding structures in Syrian hamsters were examined to document the general topography and morphology and variations and to discuss the comparative anatomy between the SCNs and ganglia in Syrian hamsters and other rodents, as well as their comparative morphology and macroscopic evolutionary changes among rodents, rabbits, domestic animals (cats, dogs, sheep, goats, oxen, pigs and horses), primates, and humans...

OBJECTIVE:  The objective of the present study was to determine the frequency of malformations and chromosomal abnormalities in a population of fetuses with an aberrant right subclavian artery (ARSA). METHODS:  This is a 6-year retrospective study of fetuses with a prenatal diagnosis of ARSA conducted during the period between September 2013 and June 2019 at a fetal medicine unit. Data were collected from ultrasound, fetal echocardiograms, genetic studies, and neonatal records...

The understanding of the synbiotics´ impact on the host is incomplete. To improve the knowledge, we study the effect of Lacto-Immuno-Vital synbiotic preparation in chickens on local and systemic immune response by evaluation of immunocompetent cells in the peripheral blood and jejunal mucosa. Hematological method was used for determination of white blood cell count, and flow cytometry for measurement the functions of phagocytes and subpopulation of lymphocytes (CD3, CD4, CD8, IgM, and IgA). Cell Qest programme (Germany) was used for analysing of data obtained from flow cytometer and GraphPad Prism version 4...

Los aneurismas de la arteria subclavia son extremadamente raros, con una incidencia reportada por diferentes autores que oscila entre el 0.01% y el 3.5%1 .

Dysphagia has several typical causes. In this case report a young adult with difficulties in swallowing since childhood is diagnosed with a rare anatomical variation of the aortal branches.

BACKGROUND: The infraclavicular puncture of the subclavian vein is a standard procedure for anesthetists. Meanwhile the literature and recommendations are clear and the use of real-time ultrasound guidance is the standard procedure; however, anesthetists will always get into special circumstances were they have to use the landmark technique, so this competence must be preserved. Feared complications of infraclavicular subclavian vein puncture are pneumothorax and arterial puncture. Up to now there is no clear learning curve for the infraclavicular subclavian vein puncture in the landmark technique performed by anesthetists...

The Southern Karaman sheep, which is very fertile in terms of meat and milk production and is often preferred in livestock raising, is known as a domestic sheep breed. The Hasak sheep is a breed formed by the triple crossbreeding of the German Black-headed, Hampshire and Akkaraman breeds. Arterial feeding of the forelimb is provided by arteria axillaris, a continuation of arteria subclavia. In this study, it was aimed to examine the forelimb arteries in Southern Karaman and Hasak sheep breeds. Totally 8 Southern Karaman and 8 Hasak sheep were obtained from Konya Bahri Dagdas International Agricultural Institute...

We developed an improved three-vessel occlusion model of global cerebral ischemia in rats. This method consists in cessation of cerebral blood flow by accessing a. carotis communis sinistra through the ventral surface of the neck as well as tr. brachiocephalicus and a. subclavia sinistra through the first intercostal space, bypassing the pleural cavity and excluding pneumothorax. After the occlusion of the vessels that resulted in interruption of their blood flow, according to laser-Doppler flowmetry, there was a sharp decline in local cerebral blood flow in the visual cortex to 4±1% of the initial level...

The literature is littered with variable and scant reports of the vertebral nerve. The present paper reviews the literature regarding this nervous structure of the neck and attempts to clarify a number of issues surrounding its form, function, and implications of surgical manipulation. The nerve may arise from the stellate ganglion or the ansa subclavia, amongst a number of other structures. Additionally, the terminal insertion of the vertebral nerve varies in the reported literature, with authors observing various terminations...

Central venous catheters (CVCs) are an important tool in the treatment of children. The insertion of a catheter may result in different complications depending of the type of catheter, the technique used for the insertion and the location. There are various techniques to reduce the risk of complications. In order to reduce the rate of complications of CVCs it is indispensable to perform a risk-benefit analysis for the individual patient before every insertion. The type of catheter used (for example tunneled catheters versus not-tunneled catheters) influences the rate of catheter-associated infections and the comfort of the patient significantly...
