Blood urea nitrogen to creatinine ratio is associated with congestion and mortality in heart failure patients with renal dysfunction
2015
Renal dysfunction (RD) and venous congestion are related and common in heart failure (HF). Studies suggest that venous congestion may be the primary driver of RD in HF. In this study, we sought to investigate retrospectively the relationship between common measures of renal function with caval congestion and mortality among outpatients with HF and RD. We reviewed data from 103 HF outpatients (45 males, mean age 74 years, ejection fraction 41.8 ± 11.6 %) with estimated glomerular filtration rate (eGFR) of 25.5 (adjusted OR 2.98, p 0.015) and eGFR ≤45.8 (adjusted OR 5.38, p 0.002) identify patients at risk for caval congestion; a BUN/Cr >23.7 was the best predictor of impaired collapsibility …
Pulmonary embolism: risk assessment and management.
2012
Acute pulmonary embolism (PE) poses a significant burden on health and survival. Its severity ranges from asymptomatic, incidentally discovered subsegmental thrombi to massive, pressor-dependent PE complicated by cardiogenic shock and multisystem organ failure. Rapid and accurate risk stratification is therefore of paramount importance to ensure the highest quality of care. This article critically reviews currently available and emerging tools for risk-stratifying acute PE, and particularly for distinguishing between elevated (intermediate) and low risk among normotensive patients. We focus on the potential value of risk assessment strategies for optimizing severity-adjusted management. Apa…
An abdominal aortic aneurysm (AAA) in combination with duplication of the inferior vena cava (IVC), the right renal artery (RRA) and the right renal …
1990
Intra-abdominal abnormality of vessels may sometimes lead to complications. A case of the rare combination of an abdominal aortic aneurysm (AAA) at the origin of the inferior mesenteric a. with duplications of the inferior vena cava (IVC), the right renal a. (RRA) and the right renal v. (RRV) as well as absence of the left common iliac v. is reported.
Comparison between CA125 and NT-proBNP for evaluating congestion in acute heart failure
2020
Abstract Background Carbohydrate antigen 125 (CA125) and B-type natriuretic peptides are surrogate markers of congestion in patients with acute heart failure (AHF). The aim of the study was to assess the association between CA125 and NT-proBNP and congestion parameters in patients with AHF. Methods and results Prospective multicentre observational study that included 191 patients hospitalised for AHF. We recorded the presence of pleural effusion, peripheral oedema and inferior vena cava (IVC) diameter during the first 24–48 h after admission and evaluated their independent association with CA125 concentrations and the amino-terminal fraction of pro-B-type natriuretic peptide (NT-proBNP). Th…
Mesenterico-caval shunt in rats
1980
A microsurgical technique for mesenterico-caval shunting in the rat is described. The method results in a partial blood drainage from the upper abdominal content whereas the blood of the mesenteric vein is shunted to the inferior caval vein. Controls were undertaken after 1 and 3 weeks, either visually or radiologically. Twenty-two of 26 surviving animals showed patency of the shunt. All animals had undisturbed blood supply to the portal stump.
MDCT and virtual angioscopy in spontaneous aortocaval fistula
2007
Aortocaval fistula is a rare, less than 1%, but life threatening complication, of abdominal aortic aneurysm. Mortality is high but prompt recognition of the fistula can reduce mortality rate. The multidetector row CT (MDCT) findings in a 69-year-old patient with a complex medical history characterized by previous episodes of myocardial ischemia, is reported. MDCT shows an early homogeneous enhancement of the inferior vena cava, slightly dilated at the liver level and markedly narrowed above the renal vein due to aneurysm compression. The patient underwent to emergency laparotomy but died during surgery for cardiac arrest. MDCT allows a prompt recognition of the fistula and different compute…
2019 ESC Guidelines for the diagnosis and management of acute pulmonary embolism developed in collaboration with the European Respiratory Society (ER…
2020
Guidelines summarize and evaluate available evidence with the aim of assisting health professionals in proposing the best management strategies for an individual patient with a given condition. Guidelines and their recommendations should facilitate decision making of health professionals in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate.

Progress in the management of acute pulmonary embolism.
2015
Purpose of review Pulmonary embolism is a major contributor to global disease burden worldwide. The 2014 guidelines of the European Society of Cardiology, endorsed by the European Respiratory Society, emphasize the need for initial and advanced risk stratification as well as risk-adapted treatment to ensure the highest quality of care. This review summarizes the progress in pulmonary embolism diagnosis, risk assessment, and treatment. Recent findings Major advances of the past 12 months include age-related biomarker cutoff levels for optimising pulmonary embolism diagnosis and risk stratification; detection of (isolated) subsegmental pulmonary embolism by computed tomographic pulmonary angi…
Abdominal and Thoracic Magnetic Resonance Angiography: Challenges, Technical Approaches, and First Clinical Applications
1993
The main goal of magnetic resonance angiography (MRA) is to enrich the huge potential of magnetic resonance imaging (MRI) by additional morphological and functional information about the vasculature. In spin echo sequences fast flowing blood leads to signal extinction, providing high contrast between tissue and vascular structures without the need for contrast media. However, various artifacts are frequently observed which alter the assessment of the vasculature. They are due to alterations of flow (slow velocity or turbulences) or induced by the acquisition technique (Mills et al. 1983; Bradley and Waluch 1985). By using gradient echo sequences, high-quality angiograms can be obtained from…
