title: Iatrogenic arteriovenous fistula of the internal mammary artery. Transcatheter intravascular coil occlusion.
abstract: We encountered a case of right internal mammary artery to innominate vein fistula following subclavian vein catheterization and the projection of the coil spring was projected after transcatheter intravascular coil occlusion. We were worried about both distal thromboembolism from small thrombi forming on a portion of the coil spring and stenosis of the subclavian artery. However, there was no evidence of thromboembolism of the distal artery, and good patency of the right subclavian artery was shown by an angiogram performed six months later. The patient has been receiving heparin therapy during hemodialysis, which should help prevent thromboembolism of the distal artery.
