Left-sided inferior vena cava (IVC) is a rare congenital venous anomaly that is most frequently detected incidentally during abdominal computer tomography scanning. However, as in the case presented, the first clinical manifestation of this anomaly may be deep venous thrombosis (DVT) of lower extremities. Therefore, left-sided IVC should be kept in mind in case of inferior DVT, especially in young patients with no predisposing thrombotic risk factors.

Given the importance of early recognition of acute venous thromboembolism (VTE) and the nonspecificity of its symptoms and signs, it is essential to follow the guidelines for diagnostic and therapeutic decisions. Ultrasound examination of the entire lower extremity is currently the standard diagnostic method for symptomatic patients with a clinical probability of deep vein thrombosis (DVT) according to the Wells scoring system. The aim of this study is to show the demographic structure and analyze the number of patients in the emergency department with suspected venous thrombosis...

The aim of this study was to determine the association of clinical presentation, the Wells scoring system and D-dimer values with MSCT pulmonary angiography. A case control study was conducted in the Emergency Department of the Clinical Hospital Sveti Duh throughout 2019. Patients with a referral diagnosis of a pulmonary embolism were included in the study. Patients were divided into two groups. The first group consisted of patients diagnosed with pulmonary embolism by MSCT pulmonary angiography or postmortem , and the second group consisted of patients excluded from pulmonary embolisms...

Chronic wounds are often underestimated condition with increasingly growing inpatient and outpatient treatment costs. Since the patient population affected by chronic wounds is heterogeneous and includes diabetes, chronic venous insufficiency and peripheral artery disease patients, with additional differences in gender, age, previous medical history, treatment of chronic wounds is highly personalized and dependent on a variety of factors. This paper aims to highlight the problems that the chronic wound patient population is facing during the COVID-19 pandemic: from higher probability of an undesirable disease outcome to the fact that many of them have limited access to primary care providers and to the regular and continuous care that their condition demands...

BACKGROUND: Iliac vein compression syndrome (IVCS) diagnosis heavily relies on an imaging test. However, non-invasive and contrast-free imaging test for the diagnosis of IVCS remains a big challenge. To address this issue, this prospective study aimed to assess the image quality and diagnostic performance of a magnetic resonance imaging technique, black-blood venous imaging (BBVI), in detecting IVCS by comparing it with contrast-enhanced computed tomography venography (CTV) and using invasive digital subtraction angiography (DSA) as the reference...

Objectives: This study aims to evaluate the diagnostic performance of machine-learning-based contrast-enhanced CT radiomic analysis for categorizing benign and malignant ovarian tumors. Methods: A total of 1,329 patients with ovarian tumors were randomly divided into a training cohort (N=930) and a validation cohort (N=399). All tumors were resected, and pathological findings were confirmed. Radiomic features were extracted from the portal venous phase images of contrast-enhanced CT...

BACKGROUND: Incidence of venous thromboembolism (VTE) after adrenalectomy for adrenal cortical carcinoma (ACC) is unknown. Herein, we aim to identify the relative incidence and risk factors of VTE after adrenalectomy for ACC. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients who underwent adrenalectomy for ACC, Cushing syndrome (CS), and benign adrenal cortical syndromes (BACS). Univariable and multivariable analyses were used to determine clinical characteristics, 30-day postoperative VTE occurrences, and associated risk factors...

Background: Phlebitis-associated peripheral infusion of intravenous amiodarone is common in clinical practice, with an incidence between 5% and 65%. Several factors, including drug concentration, catheter size, and in-line filter used, are significantly associated with phlebitis occurrence. Recently an in-line filter was recommended for the reduction of phlebitis, especially in high drug concentration regimens. We performed a retrospective propensity score-matched analysis to find out whether in-line filter will reduce the incidence of amiodarone-induced phlebitis (AIP) in high concentration of amiodarone infusion compared to low concentration without in-line filter...

BACKGROUND: The diagnosis of heart failure (HF) remains essentially clinical-Based. However, the history, physical examination, and chest radiograph findings are often inadequate in the diagnosis because multiple other conditions that affect the cardiopulmonary system mimic the symptoms of HF. N-terminal pro-BNP (NT-proBNP) has long been used for diagnosing HF. N-terminal pro-BNP values vary with different patient parameters. There is a scarcity of Indian studies on this topic. Especially with the use of newer drugs like angiotensin receptor neprilysin inhibitor (ARNI), it is important to have data from our own population on the same...

Nonalcoholic fatty liver disease (NAFLD), also named metabolic dysfunction-associated fatty liver disease (MAFLD), is a progressive disease spectrum encompassing simple steatosis, nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. It is a clinically silent disease leading to multiple extra-hepatic complications/comorbidities. It is an independent risk factor for cardiovascular disease (CVD), increasing susceptibility to hypertension, atherosclerosis, arrhythmia, myocardial dysfunction, cardiac valve deformation, and venous thrombosis through putative mechanisms including systemic inflammation, endothelial dysfunction, oxidative stress, insulin resistance, and altered lipid metabolism...

OBJECTIVES: A meta-analysis was performed to investigate the risk factors for postoperative pulmonary venous obstruction (PVO) after surgical repair of total anomalous pulmonary venous connection (TAPVC). METHODS: Data bases including PubMed, Embase, Web of Science and Cochrane Library were searched systematically. The goal was to discuss the risk factors for postoperative PVO after TAPVC. Publications were screened by 2 authors independently for criteria inclusion, methodological quality assessment and data extraction...

Adrenocortical carcinoma (ACC) accounts for a minority of all malignant tumors in adults. Surgery remains the most important therapeutic option for non-metastatic ACC. Whether a subset of patients with small ACC may benefit from minimally invasive surgery remains a debated issue, but we believe that surgeon's expertise is more important than surgical technique to determine outcome. However, even a state-of-the-art surgery cannot prevent disease recurrence that is determined mainly by specific tumor characteristics...

The differential diagnosis between adrenocortical adenomas (ACAs) and adrenocortical carcinomas (ACCs) relies on unspecific clinical, imaging and histological features, and, so far, no single molecular biomarker has proved to improve diagnostic accuracy. Similarly, prognostic factors have an insufficient capacity to predict the heterogeneity of ACC clinical outcomes, which consequently lead to inadequate treatment strategies. Angiogenesis is a biological process regulated by multiple signaling pathways, including VEGF and the Ang-Tie pathway...

BACKGROUND: The aim of this study was to identify the increased value of integrating computed tomography (CT) radiomics analysis with the radiologists' diagnosis and clinical factors to preoperatively diagnose cervical lymph node metastasis (LNM) in papillary thyroid carcinoma (PTC) patients. METHODS: A total of 178 PTC patients were randomly divided into a training ( n = 125) and a test cohort ( n = 53) with a 7:3 ratio. A total of 2553 radiomic features were extracted from noncontrast, arterial contrast-enhanced and venous contrast-enhanced CT images of each patient...

Adrenocortical carcinoma (ACC) is a rare form of cancer with an annual incidence of two per million. The risk of venous thromboembolism increases sevenfold in patients with cancer. This case report describes an iliac vein deep vein thrombosis (DVT) as an atypical presentation of an ACC and highlights the value of further imaging investigation in patients with unprovoked DVTs.

Background: Studies have reported early liver dysfunction (LD) after cardiac surgery is associated with short and long-term mortality. In this study, we aimed to investigate risk factors for persistent LD after total cavopulmonary connection (TCPC) surgery. Methods: This is a retrospective case-control study. We defined persistent LD as LDs occurring between postoperative day 1 (POD1) and POD7 and sustaining at least on POD7, while transient LD as LDs occurring between POD1 and POD7 and recovering at least on POD7...

Risk for atherosclerotic cardiovascular disease (ASCVD) shows considerable heterogeneity both in generally healthy persons and in those with known ASCVD. The foundation of preventive cardiology begins with assessing baseline ASCVD risk using global risk scores based on standard office-based measures. Persons at low risk are generally recommended for lifestyle management only and those at highest risk are recommended for both lifestyle and pharmacologic therapy. Additional "risk enhancing" factors, including both traditional risk factors and novel biomarkers and inflammatory factors can be used to further assess ASCVD risk, especially in those at borderline or intermediate risk...

We report a patient with severe coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) treated with veno-venous extracorporeal membrane oxygenation (VV ECMO) and programmed multi-level ventilation (PMLV). VV ECMO as a treatment modality for severe ARDS has been described multiple times as a rescue therapy for refractory hypoxemia. It is well known that conventional ventilation can cause ventilator-induced lung injury. Protective ventilation during VV ECMO seems to be beneficial, translating to using low tidal volumes, prone positioning with general concept of open lung approach...

Objective: Deep vein thrombosis (DVT) is the third-largest cardiovascular disease, and accurate segmentation of venous thrombus from the black-blood magnetic resonance (MR) images can provide additional information for personalized DVT treatment planning. Therefore, a deep learning network is proposed to automatically segment venous thrombus with high accuracy and reliability. Methods: In order to train, test, and external test the developed network, total images of 110 subjects are obtained from three different centers with two different black-blood MR techniques (i...

PURPOSE: To assess the effect of different kinds of biomaterials placed with maxillary sinus floor augmentation (MSFA) on bone regeneration. MATERIALS AND METHODS: Thirty-six New Zealand rabbits were used in the study. A standardized method of surgical approach was used for MSFA under anesthesia in all groups. The procedure was performed for each animal. Six separate groups with 12 cases were created. In group 1, no graft was used in MSFA. Advanced platelet-rich fibrin (A-PRF), absorbable collagen cone (ACC), venous blood, the combination of ACC and platelet-rich plasma (PRP), and the combination of ACC and enamel matrix derivative (EMD) were used in groups 2, 3, 4, 5, and 6, respectively...
