Axillary, subclavian, and brachiocephalic vein obstruction.
The consequences of occlusion of a major upper extremity vein were evaluated in eight patients with effort thrombosis, ten with thrombosis secondary to intimal injury, six with extrinsic compression, and one hypercoagulable patient, all of whom were followed for an average of 4 years. Twenty-two patients had venography, which confirmed the diagnosis but often failed to define the proximal extent of obstruction. Thirteen patients had noninvasive hemodynamic studies which did not corroborate chronic morbidity, but which were valuable in assessing the effect os specific therapy. Twelve patients were treated with anticoagulants, and six had operative removal or bypass of the obstruction. Three patients had pulmonary emboli; two embolized while on anticoagulants and both died. Swelling, pain, prominent veins, and easy fatigability of the affected extremity were the late sequelae of occlusion. Chronic morbidity was more dependent on etiology than on initial treatment. Thrombosis secondary to intimal injury caused no persistent symptoms, whether treated with anticoagulants or not. Effort thrombosis was intermediate: three fourths complained that their affected arm tired easily and half had prominent veins or persistent swelling. All of those with obstruction secondary to extrinsic compression had easy fatigability. The majority also had concomitant swelling, pain, and prominent collaterals. Operative treatment produced objective improvement in venous outflow but often was unsuccessful in relieving symptoms, particularly in patients with obstruction from extrinsic compression.
