Subclavian vein stenosis and axillary vein 'effort thrombosis'. Age and the first rib bypass collateral, thrombolytic therapy and first rib resection. Shuttleworth RD, van der Merwe DM, Mitchell WL S Afr Med J 1987 May 2;71(9):564-6.

We also report our experience with transluminal angioplasty (PTA) to restore patency to stenotic subclavian veins. The information indicates that subclavian vein stenosis occurs frequently in hemodialysis patients and is amenable to PTA. Subclavian artery stenosis is an uncommon vascular disease, showing a 4-fold left, rather than right-sided predisposition. Although a low-grade stenosis is usually asymptomatic and may remain unobserved, a severe stenosis may cause retrograde blood flow in the ipsilateral vertebral artery, leading t …. Subclavian artery stenosis is an uncommon Angiography via a transfemoral approach demonstrated a high-grade but short stenosis of the left subclavian artery . The left vertebral artery is not seen (Fig. 1 a). After traversing the stenosis and selective catheterization of the left vertebral artery (Fig.

After traversing the stenosis and selective catheterization of the left vertebral artery (Fig. 1 b), contrast injection proves retrograde flow through the patent left vertebral artery proving a subclavian steal effect. Stenosis of left subclavian vein in thoracic outlet syndrome References [1] Fugate MW, Rotellini-Coltvet L, Freischlag JA (2009) Current management of thoracic outlet syndrome. Images of the subclavian and innominate arteries were retrospectively reviewed for evidence of stenosis by an investigator unaware of sonographic results. The percentage of stenosis was calculated by comparing the lumen diameter measured at the point of maximum stenosis to the diameter of a disease-free segment of the subclavian or innominate artery distal to the stenosis. Subclavian steal syndrome (SSS), also called subclavian steal steno-occlusive disease, is a constellation of signs and symptoms that arise from retrograde (reversed) blood flow in the vertebral artery or the internal thoracic artery, due to a proximal stenosis (narrowing) and/or occlusion of the subclavian artery.This flow reversal is called the subclavian steal or subclavian steal phenomenon Twenty-two patients with subclavian steal were treated with percutaneous transluminal angioplasty (PTA). Fifteen had unilateral stenosis of the subclavian artery, one had severe stenosis on the left and total occlusion on the right, five had total subclavian occlusion on the left, and one had total occlusion of the innominate artery.

(A) Arch aortogram shows a diffusely diseased arch with critical left subclavian artery stenosis ( arrow ).Right subclavian arterial injection (B) shows antegrade right vertebral flow, crossover flow ( arrows ) into left vertebral artery (C) at level of basilar artery, and retrograde flow down left vertebral artery to reconstitute left subclavian artery (D).

Think you may have arthritis? Learn about the four most common warning signs. Information about symptoms, health and lifestyle habits will help determine the type of arth Spinal Stenosis is a disorder that is triggered by the pressure on the spinal cord and its nerves.

The disease makes the spinal canal narrow and results in back pain, nerve problems, and sciatica. Most people have pain in their lower back a Spinal stenosis causes narrowing in your spine which puts pressure on your nerves and spinal chord. It can cause pain, numbness, and foot problems.

Extracranial arterial duplex sonographic imaging was performed on a woman in her early 80s with atherosclerosis, arterial hypertension, and left arm weakness; she had a history of left subclavian artery stenosis and high-grade left internal carotid artery stenosis, and she had undergone left carotid endarterectomy two years prior to the current test.
