		A related condition is thrombosis of the subclavian vein that is induced by the presence of indwelling catheters.
		Among patients with effort-induced thrombosis with subclavian vein stenosis, the thrombosis occurs in the dominant arm in 80% of cases.
		Subclavian vein thrombi not visualized by duplex ultrasonography usually are either nonocclusive mural thrombi or thrombi located in the proximal part of the vein possibly shadowed by the clavicle and sternum.

	Subclavian Vein:
		The subclavian vein is the continuation of the axillary vein and runs from the outer border of the first rib to the medial border of scalenus anterior where it joins with the internal jugular vein to form the innominate vein (Figure 1).
		The vein is separated posteriorly from the subclavian artery by the insertion of scalenus anterior and postero-medially from the dome of the pleura by Sibson's fascia (suprapleural membrane).

		It is crossed by the internal jugular and vertebral veins, by the vagus nerve and the cardiac branches of the vagus and sympathetic, and by the subclavian loop of the sympathetic trunk which forms a ring around the vessel.
		21 Branches—The branches of the subclavian artery are: 22 Vertebral.
		The axillary artery and vein, with the brachial plexus of nerves, extend obliquely along the lateral boundary of the axilla, from its apex to its base, and are placed much nearer to the anterior than to the posterior wall, the vein lying to the thoracic side of the artery and partially concealing it.

		The subclavian arteries are separated from the veins by the anterior scalene muscle, with the artery being posterior to the muscle and the vein anterior to it.
		When it is a branch of the subclavian, it passes laterally through the trunks of the brachial plexus, anterior to the middle scalene muscle, and then runs deep to the levator scapulae to reach the scapula and supply the rhomboid muscles.
		The subclavian vein begins at the lateral border of the 1st rib as a continuation of the axillary vein and ends when it unites with the IJV, posterior to the medial end of the clavicle (SC joint).

	Subclavian artery - Wikipedia, the free encyclopedia
		The left subclavian artery is the fifth branch of the aorta and the third branch from the arch of the aorta.
		The usual branches of the subclavian on both sides of the body are the internal thoracic artery, the vertebral artery, the thyrocervical trunk, and the costocervical trunk.
		From its origin, the subclavian artery travels laterally, passing between anterior and middle scalene muscles, with the anterior scalene (scalenus anterior) on its anterior side and the middle scalene (scalenus medius) on its posterior.

		The left subclavian vein and proximal axillary vein are not opacified, so the level of stenosis can be mistaken for the mid-portion of the axillary vein.
		In one patient, CT venography clearly demonstrated focal stenosis of the left subclavian vein, which was obscured by an overlapping collateral vein, and for this same reason, ascending venography underestimated the extent of the stenosis (Fig.
		Although some flow artifacts were present in contralateral central veins and the superior vena cava, the information derived from CT venography was sufficient for diagnosis and treatment, and on the basis of the observed pattern of opacification of collateral and central veins, an understanding of the venous hemodynamics involved was facilitated.

		The axillary vein actually becomes the subclavian vein as it passes into the space between the first rib and the clavicle.
		Acute thrombosis (formation of a stationary blood clot) in the axillary and subclavian veins is uncommon and occurs in less than 4% of all deep vein thromboses.
		The axillary vein becomes the subclavian vein at the outer border of the first rib, and the internal jugular vein joins it in the base of the neck to become the innominate vein.

		The thoracic outlet is the space in the neck through which pass the nerves to the arm (the brachial plexus), the artery to the arm, (subclavian artery) and the vein which drains the arm (the subclavian vein).
		If recognized early, the fresh clot in the vein can be removed or lysed by placing a catheter into the vein and either removing the clot mechanically or chemically dissolving the clot with medicines dripped into the vein.
		After successfully decompressing the subclavian vein, webs inside the vein caused by the clot or injury of the vein may have to be treated with a balloon to fully open up the inside the vein.

		Subclavian puncture should be avoided in patients with abnormal clotting since it is difficult to apply pressure to the subclavian artery following accidental puncture.
		Initially the vein arches upwards across the first rib and then inclines medially, downwards and slightly forwards across the insertion of the scalenus anterior muscle into the first rib to enter the thorax where it joins with the IJV behind the sternoclavicular joint.
		Unlike the subclavian route, failure on one side does not prevent the operator from trying the other side although this should be discouraged if arterial puncture had occurred.

	deep vein thrombosis type of venous disease treated by vascular surgeon mumbai india
		Deep vein thrombosis (DVT) is a condition in which blood clots form in a vein deep within the body.
		It is a dangerous condition because the clot may become dislodged from the vein and travel inside the vein all the way to the lung, where it may get trapped and block a vessel in the lung.
		Partial interruption of the inferior vena cava (the vein that carries blood from the lower body to the right side of the heart) using clips, sutures (stitches) or filters prevents the blood clot from reaching the lung.

		We agree with the authors that a spiral saphenous vein graft is both cumbersome to fashion and not as durable as an internal jugular vein graft.
