Abstract:
Objective To explore the relationship between the impact of blood flow (the flow from right atrium and hepatic vein), diaphragm movement and the pathogenesis of membranous obstruction of inferior vena cava(MOVC). Methods Twenty cadavers were involved, measuring widths of inferior vena cava (IVC )at the diaphragmatic hiatus and the thoracic cage; and taking the IVC segment between the diaphragmatic hiatus and hepatic vein for tissue examination of IVC intimal thickness and type I collagen accumulation as group A and comparing with those of IVC above level of renal vein in Group B. Results IVC intimal thickness and type I collagen distribution area of Group A were greater than those of group B, showing statistically significant difference (P
