Left main renal artery entrapment by diaphragmatic crura: spiral CT angiography

Left main renal artery entrapment by diaphragmatic crura: spiral CT angiography

Entrapment of renal artery by the diaphragmatic crus is a rare cause of renal artery stenosis. Spiral computed tomography angiography provides a definitive diagnosis and shows the precise relationship of the artery to the diaphragmatic crus. The authors present a case of hypertension developing in a young 20-year-old female due to entrapment of the left renal artery by the diaphragmatic crus. T...

Coronary CT Angiography Findings in Patients with Ambiguous Left Main Coronary Artery Disease

Left main coronary artery (LMCA) stenosis is a high risk subset of coronary artery disease; however, its occurrence may be misjudged by coronary angiography. Coronary CT angiography (CCTA) was performed on 5 patients with clinically highly suspicious and angiographically borderline LMCA disease (ostial: 3 patients, mid: 1 patient and distal: 1 patient). A cross-sectional CCTA image was used to ...

Spontaneous left main coronary artery dissection complicated by pseudoaneurysm formation in pregnancy: role of CT coronary angiography

We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary t...
