Right internal mammary artery (RIMA) angiogram

Right subclavian angiogram showing right internal mammary artery

Radiocontrast has been injected into the right subclavian artery using a catheter introduced by the right femoral arterial route. Reft vertebral artery (R Vertebral) is seen coursing up from the right subclavian artery (RSA). Right internal mammary artery (RIMA) is seen coursing down from the subclavian after the origin of the right vertebral artery. RIMA angio is needed when we are planning total arterial revascularisation harvesting both RIMA and LIMA (left internal mammary artery). It is also needed when the LIMA has been used during the previous coronary artery bypass grafting as in this case. In this case injection of the left subclavian artery had shown that the LIMA is occluded.
