Treating complications of subclavian vein puncture by embolization of the internal mammary artery.
Embolization therapy is reported in 2 patients who had vascular complications following percutaneous subclavian vein catheterization. One had an arteriovenous fistula between the right internal mammary artery (IMA) and the brachiocephalic vein. The other patient presented with a pseudo-aneurysm of the IMA with life-threatening hemorrhage and a large thoracic hematoma. A detachable latex balloon was used for occlusion of the arteriovenous fistula in the first patient and a steel spring coil was used to embolize the IMA and the pseudo-aneurysm in the second patient. The lesions were successfully treated on follow-up of 30 months for the first patient and 37 months for the other.
