Magnetic Resonance Angiography of an Aortic Dissection

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...

Magnetic Resonance Angiography Source Images of Vertebral-artery Dissection

A 62-year-old man was admitted to our hospital with a brain infarction in the right medulla. On the first day, he was diagnosed with a vertebral artery dissection, based on the findings from conventional angiography, which showed an irregular stenosis associated with a pseudoaneurysm of the right vertebral artery (Picture 1). This finding on classical angiography is called the pearl and string ...

Resonance Angiography of Cervicocranial Dissection

Background: A retrospective study of five patients with the clinical or magnetic resonance-based diagnosis of carotid dissection was done. Clinical data, imaging studies, treatment, and outcome were reviewed. The potential applicability of three-dimensional time-of-flight magnetic resonance angiography in these settings was evaluated. Summary of Report: This modality reliably showed vascular ab...

Magnetic Resonance Angiography of Aortic Diseases in Children

Assessment of interrupted aortic arch with magnetic resonance angiography.

A 22-year-old man was referred to our cardiology department for investigation of hypertension. At presentation his blood pressure was 170/100 mmHg in both arms, and heart rate was 74 beats/min. The pulses were equal over both upper extremities, but bilateral femoral and popliteal pulses were extremely weak and the dorsalis pedis and anterior tibial pulses were not palpable. His past history was...
