A venogram of the bilateral upper extremities to assess for stenosis.The left brachial vein was accessed under ultrasound guidance.The venogram demonstrated multiple stenosis in the left subclavian vein.Balloon angioplasty was performed with 6mm, 8mm, and 10mm balloons.After 2 inflations with the 10mm balloon, the balloon ruptured, and contrast was noted in the subclavian vein.Under fluoroscopic guidance, the balloon catheter was pulled back into the sheath and resistance was noted.Under steady pressure the catheter was withdrawn from the sheath, but resistance was again noted when the balloon catheter was out of the sheath.At this point, the sheath and balloon were withdrawn from the left brachial vein and skin.Additional resistance was noted.Assessment at this point was that the balloon catheter was stretched and sheared with near separation of the balloon portion of the catheter with a portion external to the left arm and a portion that was likely intravascular in the left brachial vein.The proximal portion of the balloon catheter and sheath were removed over a wire.At this point, consult with vascular surgery was obtained.A small cut-down to the left brachial vein to extract the foreign body was performed.
