Narrowing of the upper abdominal inferior vena cava in patients with elevated intraabdominal pressure

Abstract

Narrowing of the upper intrahepatic IVC can be seen in some patients with increased IAP. The cause and significance of this phenomenon remain to be determined.

Does a Simple Bedside Sonographic Measurement of the Inferior Vena Cava Correlate to Central Venous Pressure?

“…Changes in intra-abdominal and intrathoracic pressures (e.g., during positive-pressure ventilation or Valsalva maneuver) are also well known to alter the CVP and have some effect on IVC diameters (41)(42)(43)(44). Our subject population was a mixture of patients receiving positive-pressure ventilation and those breathing spontaneously.…”

Can Chronic Intra-Abdominal Hypertension Cause Oxidative Stress to the Abdominal Wall Muscles? An Experimental Study

“…The incidence of obesity is constantly increasing worldwide and has become an epidemic. The consequences of morbid obesity are very well studied and proved [18][19][20][21][22][23]. However, the pattern of pathophysiologic changes that lead to the clinical consequences of morbid obesity is far from being clarified.…”

Modern imaging techniques in intra-abdominal hypertension and abdominal compartment syndrome: a bench to bedside overview

“…Only a few small studies have identified characteristic CT imaging features of IAH and ACS [4][5][6][7][8]. Key to ACS management is acknowledging that IAH is secondary to underlying pathology, frequently systemic inflammatory response syndrome (SIRS), bleeding, or fluid extravasation [9].…”
