Pathophysiology of Portal Hypertension [PDF]

Clinics in Liver Disease, 1964
Portal hypertension is a major complication of liver disease that results from a variety of pathologic conditions that increase the resistance to the portal blood flow into the liver. As portal hypertension develops, the formation of collateral vessels and arterial vasodilation progresses, which results in increased blood flow to the portal circulation.

Fractal Anatomy of Human Organs: A Narrative Review of Structure, Function, and Clinical Perspectives

Clinical Anatomy, EarlyView.
ABSTRACT Fractal geometry describes complex, self‐similar patterns that repeat across spatial scales and is increasingly recognized as relevant in anatomical research. Indeed, the fractal organization is consistently observed in respiratory, cardiovascular, gastrointestinal, nervous, renal, hepatic, and dermatological systems.

Dynamics of urinary chloride and sodium and their link to decongestion in acute heart failure and preserved ejection fraction: NACLOCRo‐HF study

ESC Heart Failure, EarlyView.
The study evaluated urinary chloride (uCl) and sodium (uNa) trajectories in 70 elderly patients hospitalized with acute heart failure and preserved ejection fraction (HFpEF). Urine samples were collected at baseline, 24, 48 and 72 h. A multiparametric approach assessed decongestion using the clinical congestion score (CCS), portal vein (PV) pulsatility

Prediction of survival and analysis of prognostic factors for patients with AFP negative hepatocellular carcinoma: a population-based study

BMC Gastroenterology
Purpose Hepatocellular carcinoma (HCC) has a poor prognosis, and alpha-fetoprotein (AFP) is widely used to evaluate HCC. However, the proportion of AFP-negative individuals cannot be disregarded.

Liver stiffness measurement for non‐invasive assessment of central venous pressure in patients with heart failure: A multicentre pilot study

European Journal of Heart Failure, EarlyView.
Liver stiffness measurement for central venous pressure assessment. AUC, area under the curve; BMI, body mass index; CI, confidence interval; CVP, central venous pressure; HF, heart failure; LSM, liver stiffness measurement; LVEF, left ventricular ejection fraction. Abstract Aims Central venous pressure (CVP) is an important variable in assessing heart
