Figure 4. Digital subtraction angiography with early and late phase demonstrating (A) left subclavian artery occlusion with (B) retrograde vertebral filling of proximal subclavian artery.

Expert Rev Cardiovasc Ther. 2010;8(9):1275-1282. Finally, we examined our own experience with a 9-year follow-up of primary stenting, which is one of the longest to date. A total of 91 patients ...

Vertebral angiography was pioneered by Moniz and Alves in 1936, and initially performed by exposure and direct injection of subclavian or vertebral arteries. 1 A percutaneous lateral atlanto-occipital ...

The vertebral-basilar system supplies the brain-stem, cerebellum and temporal and occipital lobes 2 (Fig. 1). It begins as the vertebral artery, which is the first branch of the subclavian artery.

(A) Right subclavian artery and (B) right innominate artery injections in left anterior oblique projection demonstrate complete occlusion of the vertebral artery shortly beyond its origin (black arrow ...

We performed a redo-partial upper median sternotomy and dissected free the innominate artery and origins of the right subclavian artery and common carotid artery (Figure 3). The right internal mammary ...

These arteries unite at the base of the brain to form the basilar artery, and in a healthy person they supply up to 20% of the brain’s blood. Normally, the blood in the vertebral arteries flows ...

From the Cardiovascular Surgical Section, Veterans Administration Hospital, Oteen, North Carolina. Five patients with subclavian artery stenosis, reversed vertebral artery blood flow, and basilar ...

Introduction Abnormal origins of the right vertebral artery (RVA) are uncommon, occurring at a rate of 0.18% in the general population (1). Right subclavian artery (RSCA) variants are primarily ...

Background Subclavian steal syndrome (SSS) is a relatively rare syndrome. It occurs when the subclavian artery, usually the left, is occluded proximal to the origin of the vertebral artery. 1 ...

Subclavian steal syndrome is a circulation issue. It occurs when blood flow reverses in an artery. Read about symptoms, causes, treatment, and more.
