Venous TOS occurs when a blood clot forms in the large vein that drains the arm. Doctors should suspect this type of TOS when a patient presents with arm swelling and color changes. Many available\u00a0<a href=\"https:\/\/www.tosmri.com\/diagnosis-of-thoracic-outlet-syndrome\/diagnosis-of-venous-thoracic-outlet-syndrome\/\">diagnostic tests<\/a>\u00a0can easily demonstrate the blood clot. Treatment of this type of TOS is urgent, and doctors usually strive to dissolve the blood clot quickly.\n\nA single, large subclavian vein drains the blood from each arm. Compression of this vein can prevent normal venous drainage of the arm. When compression is repetitive, severe, or prolonged, it can cause damage to the inner wall of the vein. As a result of this damage, blood clot can form within the vein. In this event, swelling, heaviness and cyanosis (abnormal blue color) develops in the affected arm. Some patients may develop new superficial veins of the chest and shoulder, as blood must return to the heart through new pathways.\n\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-eb0f5a6 e-con-full e-flex e-con e-child\" data-id=\"eb0f5a6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-d988b29 e-con-full e-flex e-con e-parent\" data-id=\"d988b29\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-4a4d6a7 e-con-full e-flex e-con e-child\" data-id=\"4a4d6a7\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-ecde190 elementor-widget elementor-widget-text-editor\" data-id=\"ecde190\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>When a doctor sees a patient with this clinical picture, they should immediately consider the diagnosis of venous TOS. This type of TOS accounts for about 2 to 5% of all TOS cases. Quick and accurate diagnosis is vital to prevent complications such as blood clot fragments traveling to the lungs or, rarely, to the brain, causing a stroke.<\/p><p><a href=\"https:\/\/www.tosmri.com\/treatment-of-thoracic-outlet-syndrome\/treatment-of-venous-thoracic-outlet-syndrome\/\">Treatment of venous thoracic outlet syndrome<\/a>\u00a0should begin urgently, using methods to dissolve or remove the blood clot in the subclavian vein. After this, imaging studies can show whether the vein is damaged or compressed by external structures. If these structures are not removed or reduced, the same damage and blood clot may recur, resulting in the same type of TOS.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-abb9f9f elementor-widget elementor-widget-button\" data-id=\"abb9f9f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/hlsllc.org\/tos\/venous-tos\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Venous Thoracic Outlet Syndrome<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4b8d129 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"4b8d129\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-69522fb e-con-full e-flex e-con e-child\" data-id=\"69522fb\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ceb133d e-con-full e-flex e-con e-parent\" data-id=\"ceb133d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-f89059d e-con-full e-flex e-con e-child\" data-id=\"f89059d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9e75b13 elementor-widget elementor-widget-heading\" data-id=\"9e75b13\" data-element_type=\"widget\" data-e-type=\"widget\" id=\"toc_Arterial_Thoracic_Outlet_Syndrome\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Arterial Thoracic Outlet Syndrome\n<\/h2>\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-dfae129 e-con-full e-flex e-con e-child\" data-id=\"dfae129\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-716bdb8 e-con-full e-flex e-con e-child\" data-id=\"716bdb8\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-77fd51e elementor-widget elementor-widget-image\" data-id=\"77fd51e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/hlsllc.org\/tos\/wp-content\/uploads\/2026\/04\/Gray-retropectoralis-space-artery-plexus-cropped.jpg\" class=\"attachment-large size-large wp-image-20175\" alt=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-8be684f e-con-full e-flex e-con e-child\" data-id=\"8be684f\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-77e81cc elementor-widget elementor-widget-text-editor\" data-id=\"77e81cc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Arterial TOS is the rarest type of TOS. This type of TOS occurs when compression of the subclavian artery causes arterial damage, with secondary blood clot causing symptoms. Blood clot forms in the damaged arterial segment, and fragments travel down the arm, creating the sudden severe blockage of blood flow. Doctors typically recognize\u00a0arterial thoracic outlet syndrome quickly, and treat it by removing the clot emergently.<\/p><p>Arterial TOS develops after\u00a0<a href=\"https:\/\/www.tosmri.com\/what-is-thoracic-outlet-syndrome\/causes-of-thoracic-outlet-syndrome\/causes-of-arterial-thoracic-outlet-syndrome\/\">compression of the subclavian artery<\/a>\u00a0causes arterial damage or blood clot. The subclavian artery provides blood flow to each arm. Repetitive and severe compression of this artery in the thoracic outlet causes damage to the arterial wall. Damage limited to the inner arterial wall can cause a fixed scar and\u00a0<i>stenosis<\/i>\u00a0(narrowing of the artery). In contrast, damage to the full thickness of the wall can result in an\u00a0<i>aneurysm<\/i>\u00a0(focal ballooning of the artery). Arterial blood clots may form in the damaged arterial segment. Blood clots can break off and travel down the arm and block distal arteries, causing sudden and severe loss of blood flow. Doctors call this process\u00a0<i>acute arterial insufficiency<\/i>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5546509 e-con-full e-flex e-con e-parent\" data-id=\"5546509\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-97b4ad4 e-con-full e-flex e-con e-child\" data-id=\"97b4ad4\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0ac6735 elementor-widget elementor-widget-text-editor\" data-id=\"0ac6735\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Arterial TOS accounts for about 1% of all TOS cases. Most patients with this arterial TOS present with an acute onset of symptoms, including pain and loss of pulses. It is important to realize that if not treated emergently, loss of tissue (gangrene) may occur. Therefore, doctors need to recognize and treat this arterial TOS emergently. Initial treatment requires emergent removal or dissolving of the arterial blood clot. Imaging tests can then show the damaged arterial segment and the external structures that caused the damage. Later, doctors typically repair the damaged arterial segment and remove or release the abnormal external structures causing compression of the artery.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e5c698d elementor-widget elementor-widget-button\" data-id=\"e5c698d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/hlsllc.org\/tos\/arterial-tos\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Arterial Thoracic Outlet Syndrome<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-a3bccb6 e-con-full e-flex e-con e-child\" data-id=\"a3bccb6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-247e838 e-con-full e-flex e-con e-parent\" data-id=\"247e838\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-84c474a elementor-widget elementor-widget-heading\" data-id=\"84c474a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Do you have questions about thoracic outlet syndrome?\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a2b4938 elementor-widget elementor-widget-heading\" data-id=\"a2b4938\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">We can help!\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-54eaac4 elementor-widget elementor-widget-button\" data-id=\"54eaac4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"#\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Contact us<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-bab881f e-con-full e-flex e-con e-parent\" data-id=\"bab881f\" data-element_type=\"container\" data-e-type=\"container\" id=\"toc_Can_multiple_types_of_thoracic_outlet_syndromeoccur_in\">\n\t\t<div class=\"elementor-element elementor-element-8b2b7f8 e-con-full e-flex e-con e-child\" data-id=\"8b2b7f8\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-296239b elementor-widget elementor-widget-heading\" data-id=\"296239b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Can multiple types of thoracic outlet syndrome occur in the same patient?\n\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a06e619 elementor-widget elementor-widget-text-editor\" data-id=\"a06e619\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<div class=\"fusion-text fusion-text-18\"><p>Yes! One patient can have multiple types of thoracic outlet syndrome\u00a0at the same time.\u00a0As shown above, the artery, vein, and brachial plexus pass through each thoracic outlet together. Thus, a patient can have compression of 1, 2, or all 3 of these vital structures. In fact, many patients with neurogenic TOS also have compression of the subclavian vein, but without a blood clot. In that case, compression may impair venous drainage of the arm. As a result, swelling or edema of the arm can result. This swelling can magnify compression of the brachial plexus. In that case, treatment to relieve the venous compression helps relieve compression on the brachial plexus.<\/p><p>It is often difficult for a physician to distinguish the multiple compression effects occurring when a patient has components of multiple types of thoracic outlet syndrome.
