Venous hypertension

KEY CLINICAL MESSAGE: Our case highlights the importance of recognizing acromegaly as a potential risk factor for venous thromboembolism (VTE). Despite a thorough thrombophilia workup yielding unremarkable results, further research is warranted to elucidate the underlying mechanisms linking acromegaly and thrombophilia. This understanding will aid in improving risk assessment and management strategies for patients with acromegaly. ABSTRACT: Acromegaly, a rare disorder characterized by excessive growth hormone secretion, is associated with various comorbidities including hypertension, diabetes mellitus, and obstructive sleep apnea...

INTRODUCTION: Raised intracranial pressure (ICP) can be due to varied etiology. Differentiating among these various etiologies is crucial in making appropriate therapeutic decisions. A patient with a known past history of the primary or secondary headache of any etiology, when presenting with new onset severe headache, needs to be evaluated with imaging to rule out an alternative diagnosis. DISCUSSION: Here, we describe the case details of a young lady who presented with recurrent raised ICP headaches due to three different etiologies...

IMPORTANCE: COVID-19 has disproportionately affected racialized populations, with particular impact among individuals of Black individuals. However, it is unclear whether disparities in venous thromboembolic (VTE) complications exist between Black individuals and those belonging to other racial groups with confirmed SARS-CoV2 infections. OBJECTIVE: To summarize the prevalence and moderators associated with VTE among Black COVID-19 patients in minoritized settings, and to compare this to White and Asian COVID-19 patients according to sex, age, and comorbid health conditions (heart failure, cancer, obesity, hypertension)...

Despite the end of the pandemic, coronavirus disease 2019 (COVID-19) remains a major public health concern. The first waves of the virus led to a better understanding of its pathogenesis, highlighting the fact that there is a specific pulmonary vascular disorder. Indeed, COVID-19 may predispose patients to thrombotic disease in both venous and arterial circulation, and many cases of severe acute pulmonary embolism have been reported. The demonstrated presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within the endothelial cells suggests that direct viral effects, in addition to indirect effects of perivascular inflammation and coagulopathy, may contribute to pulmonary vasculopathy in COVID-19...

Preeclampsia (PE) is a hypertensive disorder in pregnancy associated with significant fetal and maternal complications. Antiphospholipid syndrome (APS) is an acquired form of thrombophilia characterized by recurrent venous or arterial thrombosis and obstetric complications that significantly increases morbidity and mortality rates. While preeclampsia may not be the most prevalent obstetric complication in APS, it significantly impacts the long-term health of both mother and child. The treatment of preeclampsia in antiphospholipid syndrome is different from the treatment of preeclampsia as an independent disease...

OBJECTIVES: Tegmen and superior semicircular canal defects have been well studied, yet the factors contributing to their onset and progression are widely debated. The clinical utility of intraoperative intracranial pressure measurements has yet to be tested. This report aims to use intraoperative opening pressure and concurrent superior semicircular canal dehiscence (SSCD) to analyze factors influencing disease course and clinical outcomes in patients with tegmen dehiscence. METHODS: A retrospective analysis of 61 patients who underwent tegmen defect repair was performed...

Objectives: The aim of the study was to examine the incidence, baseline characteristics, and outcomes of Chimeric Antigen Receptor T-cell (CAR-T) therapy admissions in individuals who developed acute respiratory failure (ARF). The study utilized the National Inpatient Sample (NIS) database for the years 2017 to 2020. Methods: The study identified CAR-T cell therapy hospitalizations through the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) codes. Patients with acute respiratory failure (ARF) were further classified using specific International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM) codes...

BACKGROUND: Partial anomalous pulmonary venous return (PAPVR) can be surgically corrected using a pericardial baffle. This baffle can become obstructed post-surgery, leading to pulmonary hypertension and right heart dysfunction if not detected and corrected. CASE SUMMARY: We describe three patients with occluded PAPVR baffles who underwent drug-coated balloon angioplasty and stenting of the obstructed baffle. In each case, baffle obstruction was detected post-operatively on surveillance cross-sectional imaging, and an invasively measured pulmonary capillary wedge-to-left atrium gradient was noted to be elevated...

A 73-year-old man with a history of hypertension, hyperlipidemia, and obesity presented for cardiovascular evaluation. He was experiencing mild fatigue and dyspnea on exertion. Transthoracic echocardiogram (TTE) showed right ventricular dilation, which was otherwise unremarkable.

BACKGROUND: The use of extracorporeal membrane oxygenation (ECMO) technology has significantly decreased mortality rates associated with neonatal pulmonary hypertension and respiratory failure. Prone positioning ventilation (PPV) is a commonly used technique in critically ill infants, designed to improve thoracic pressure gradients, re-expand dorsal lung segments, and increase oxygenation in approximately 70-80% of patients suffering from acute respiratory distress syndrome. This study aimed to evaluate the effects of PPV on pulmonary function in neonates undergoing venous-arterial extracorporeal membrane oxygenation (VA-ECMO)...

BACKGROUND: The course of coronavirus disease 2019 (COVID-19) is associated with the progression of a wide range of complications, among which thrombosis and thromboembolism are of particular importance. The significance of hypoalbuminemia in the development of thromboembolic complications (TECs) in patients with a severe course of COVID-19 is currently under active discussion. The objective of our study was to evaluate the significance of hypoalbuminemia in the development of TECs in patients with severe SARS-CoV-2 coronavirus infection...

Venous sinus stenting for dural venous sinus outflow obstruction due to an intrinsic filling obstruction or extrinsic stenosis is an increasingly popular treatment strategy for idiopathic intracranial hypertension (IIH) and isolated pulsatile tinnitus (PT). The most common site of stenosis is the lateral venous sinus at the transverse-sigmoid junction. Approximately 10% of the population has a persistent occipital venous sinus (OVS), a variant that may be the dominant venous drainage pathway in the setting of a hypoplastic or aplastic transverse sinus...

INTRODUCTION: In this study, we investigate the evolution of lumbar fusion surgery with robotic assistance, specifically focusing on the impact of robotic technology on pedicle screw placement and fixation. Utilizing data from the Nationwide Inpatient Sample (NIS) covering 2016 to 2019, we conduct a comprehensive analysis of postoperative outcomes and costs for single-level lumbar fusion surgery. Traditionally, freehand techniques for pedicle screw placement posed risks, leading to the development of robotic-assisted techniques with advantages such as reduced misplacement, increased precision, smaller incisions, and decreased surgeon fatigue...

In situ pulmonary arterial thrombosis (ISPAT) refers to the formation of new blood clots in the pulmonary arterial system in the absence of pre-existing clots in the peripheral venous system. With the emergence and prevalence of COVID-19, ISPAT has become an increasingly important cause of pulmonary arterial thrombosis (PAT) alongside thromboembolism. Several factors such as hypoxia, inflammation, endothelial dysfunction, and hypercoagulable state can lead to ISPAT, which is associated with a number of conditions such as thoracic trauma, partial lung resection, pulmonary infectious disease, pulmonary vasculitis, connective tissue diseases, severe pulmonary hypertension, radiation pneumonitis, and acute chest syndrome in sickle cell disease...

Chronic thromboembolic pulmonary hypertension (CTEPH) is classified as group IV pulmonary hypertension, characterized by thrombotic occlusion of the pulmonary arteries leading to vascular stenosis or obstruction, progressive increase in pulmonary vascular resistance and pulmonary arterial pressure, and eventual right heart failure. Unlike other types of pulmonary hypertension, the prognosis of CTEPH can be significantly improved by surgery, vascular intervention, and/or targeted drug therapy. Pulmonary endarterectomy (PEA) is the preferred treatment of choice for CTEPH...

INTRODUCTION: There are many options for the reduction of portal hypertension (PH) in cirrhotic patients, but all the current ones have side effects. Probiotics are a new approach for ameliorating the hyperdynamic circulation of cirrhotic patients. The aim of this study is to measure the effect of probiotics on PH in cirrhosis for the first time. METHODS: A search was conducted across four electronic databases (PubMed, Scopus, Web of Science, Cochrane) for English-language records evaluating probiotic effects on pH in cirrhotic patients...

May-Thurner syndrome or left iliac vein compression occurs when the left common iliac vein is compressed by the right common iliac artery, leading to venous outflow obstruction. This obstruction can cause venous hypertension, resulting in lower extremity swelling, discoloration, pelvic congestion, and venous ulcerations. The standard surgical treatment of May-Thurner syndrome is endovascular venous stent placement. In a small, single-center sample, surgical anteriorization of the left common iliac vein was used to treat symptomatic left common iliac vein compression in younger patients, alleviating their symptoms, and can be considered an alternative treatment...

BACKGROUND & AIMS: Major bleeding events during orthotopic liver transplantation (OLT) are associated with poor outcomes. The proportion of this risk related to portal hypertension is unclear. Hepatic venous pressure gradient (HVPG) is the gold standard for estimating portal hypertension. The aim of this study was to analyze the ability of HVPG to predict intraoperative major bleeding events during OLT in patients with cirrhosis. METHODS: We retrospectively analyzed a prospective database including all patients with cirrhosis who underwent OLT between 2010 and 2020 and had liver and right heart catheterizations as part of their pre-transplant assessment...
