Aortic coarctation diagnosed by magnetic resonance angiography

Intercostal artery aneurysm postcoarctation repair diagnosed by magnetic resonance angiography.

A 69-year-old man was referred for investigation of a right upper chest mass. In 1965 he had an aortic coarctation resected with Dacron graft insertion. He remained asymptomatic for the intervening 33 years before presenting with breathlessness on exertion. A chest x-ray showed a right upper lobe mass, and computed tomography showed a descending aorta aneurysm. Cardiovascular magnetic resonance...

Magnetic resonance angiography of an aortic dissection.

A 51-year-old man with hypertension had previously been admitted to our cardiothoracic unit with a type A aortic dissection (Stanford classification) and had undergone emergency surgery with partial replacement of the ascending aorta. Routine follow-up magnetic resonance angiography (MRA) 19 months after the operation revealed an aneurysm at the incision site in the ascending aorta and extensio...

Blood Flow Simulation in an Aorta with a mild coarctation Using Magnetic Resonance Angiography and Finite Volume Method

Coarctation of the aorta is one of the five main congenital cardiovascular failures, accounting for 6–8 percent of these failures. This research aimed to simulate the blood flow of a seventeen-year-old male teen with a mild coarctation at one-third of his aorta's descending branch. The simulation was performed by extracting the domain and the input pulsatile velocity signal as the boundary cond...

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...
