چکیده
A 58 year old man was admitted with atrial fibrillation and lower limb swelling without abdominal pain. Computed tomography angiography (CTA) showed an isolated aortocaval fistula (ACF) secondary to aortic aneurysm (85 mm) rupture. The patient underwent urgent Gore C3 Excluder (W. L. & Associates, Flagstaff, AZ, USA) endograft placement immediate symptom resolution. Post-processing imaging software (Global Illumination Rendering v7.0; Vital Images, Canon Medical Systems, Paris, France; 2000 × pixels/300 dpi) allowed three dimensional reconstruction of blood flow on pre-operative CTA (A), later identifying a small ACF fed by type II endoleak (B), noted have resolved the two month surveillance CTA.Figure 1

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 کاملCan coronary computed tomography angiography replace invasive angiography? Coronary computed tomography angiography cannot replace invasive angiography.
O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....
متن کاملComputed tomography coronary angiography.
Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...
متن کاملCoronary Computed Tomography Angiography
Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...
