MITZNER, WAYNE. Hepatic outJrow resistance, sinusoid pressure, and the vascular waterfall. Am. J. Physiol. 227(3): 513-519. 1974.The pressure-flow characteristics of the hepatic common outflow resistance were determined in five anesthetized dogs. These curves were shown to be nearly linear in the range of normal flows, but exhibited a moderate convexity toward the pressure axis at low flows. Th...

We have attempted to evaluate the degree to which hepatic arterial infusion of 5-fluoro-2 -deoxyuridine (FdUrd) or 5-fluorouracil produces higher hepatic and lower systemic drug concentrations than are achieved with corresponding peripheral venous infusions. Hepatic arterial catheters were placed for therapy in 15 patients with primary or metastatic liver cancer. Temporary he patic venous cathe...

59 decompression with small diameter PTFE interposi-tion grafts. The confirmation of Sarfeh's experience of durable patency with the use of small diameter ringed PTFE interposition prosthetic grafts appears to have allayed residual reservations about this procedure. Further experience over more extended periods will be required to establish whether it will truly match the excellent long term pa...

BACKGROUND Iliocaval venous obstruction (ICVO) can be a significant contributor to venous hypertension in patients with advanced disease. The incidence of ICVO in patients with CEAP clinical class 5 and 6 disease has not been reported. In this study, we reviewed a series of patients with healed or active venous leg ulcers to determine the incidence of ICVO and the risk factors related to its oc...

INTRODUCTION A distended urinary bladder has been known to cause venous obstruction or rarely bowel obstruction. We report the first case in the literature in which urinary bladder distension presented with both venous obstruction and constipation. This is an unusual presentation of urinary bladder distension and serves to broaden our differential diagnoses for a patient with clinical venous ob...

RATIONALE Superior vena cava syndrome (SVCS) is the obstruction of blood flow through the SVC, causing complete or partial blockade of the collateral circulation of returning venous blood. SVCS is frequently presented with facial, neck, trunk, and upper limbs swelling and so on. However, to the best of our knowledge, the obstruction of the venous return in the spinal veins is rarely a manifesta...
