Bypass surgery with the internal mammary artery graft: 15 year follow-up.

abstract：BACKGROUND:Treatment of aortocaval fistulae (ACFs) by open surgery is known to be a high-risk procedure. In this experimental study, we developed a percutaneous model of ACF to test a new nonsurgical method of treatment of ACF using endovascular stent grafts. METHODS AND RESULTS:An ACF was created percutaneously in ei...
