An aortocaval fistula diagnosed with 1.5-T magnetic resonance angiography.
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...
متن کاملAortocaval Fistula
A 77-year-old Caucasian male with a history of hypertension presented with sudden onset of lower back pain, nausea, and vomiting. Initial vital signs included a pulse rate of 104 beats/minute, a blood pressure of 117/72 mm Hg, and pulse oximetry of 95% on room air. Abdominal examination revealed a midline pulsatile mass and bruit. The patient had bilateral lower extremity edema, which was worse...
متن کاملDistal Lower Extremities: Prospective Comparison of 2D Time-of-Flight, 3D Time-Resolved Contrast-Enhanced MR Angiography, and 3D Bolus Chase Contrast-Enhanced MR Angiography
W. Y. Hahn, E. M. Hecht, B. Friedman, V. S. Lee NYU Medical Center, New York, NY, United States SYNOPSIS: Magnetic resonance angiography of the calf and pedal arteries is challenging due to the issues of venous contamination and small vessel size. Therefore, contrast-enhanced MRA is typically supplemented with TOF imaging below the knee. In this study, we compared the conventional TOF sequence ...
متن کاملAortocaval Fistula in a Behcet's Disease Patient
Behcet's disease (BD) is a chronic, recurrent, systemic disease that is characterized by oral and genital ulcers and oculocutaneous inflammatory lesions. Cardiovascular involvement especially large artery involvement is a serious and vital complication of BD. Pseudoaneurysms in the major arteries may be the cause of sudden death in BD. In our case a pulsatile abdominal mass was determined to be...
متن کاملThe mouse aortocaval fistula recapitulates human arteriovenous fistula maturation.
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 ...
