We report a case of aortocaval fistula demonstrated with gadolinium-enhanced magnetic resonance (MR) angiography. Specific radiographic features of this rare complication, such as early and intense enhancement of the inferior vena cava, are underlined with MR imaging. The exact location of the fistula can also be assessed with this noninvasive imaging technique. Moreover, the absence of iodinat...
Several models of arteriovenous fistula (AVF) have excellent patency and help in understanding the mechanisms of venous adaptation to the arterial environment. However, these models fail to exhibit either maturation failure or fail to develop stenoses, both of which are critical modes of AVF failure in human patients. We used high-resolution Doppler ultrasound to serially follow mice with AVFs ...
This study describes an alternative arteriovenous fistula (AVF) model in the rat in which the animals develop significant neointimal hyperplasia (NIH) not only at the distal anastomotic site, but also throughout the fistula body. This aortocaval fistula was established by anastomosing the distal end of the renal vein to the abdominal aorta after unilateral nephrectomy. The increased hemodynamic...
