Microcoil embolization of large intercostal branches of internal mammary artery
A meta-analysis comparing bilateral internal mammary artery
with left internal mammary artery
for coronary artery bypass grafting.
The internal mammary artery
and the anterior descending artery were inosculated by continuous suture, as well as the anastomosis of great saphenous vein graft far-end, vein graft and the aorta ascendens.
913 In our patient the use of 250mL of contrast and difficulty in engaging LIMA as the internal mammary artery
and vertebral artery arose from close vicinity.
The platelet count gradually came down to 459 x 10(9)/ L and the patient underwent CABG, grafting left anterior descending artery, intermediate artery and posterior descending artery using internal mammary artery
and vein conduits consequently.
Within the hematoma, a small region of arterial extravasation from injury to the left internal mammary artery
(IMA) was identified.
Cho adds that it's easier to reach an artery that has been grafted to the heart in a previous bypass surgery, especially a left internal mammary artery
(LIMA), if a doctor takes the femoral approach.
Left internal mammary artery
and a saphenous vein graft were anastomosed to LAD and circumflex artery respectively.
A 67-year-old man underwent triple coronary artery bypass graft surgery (left internal mammary artery
to left anterior descending artery, saphenous vein autograft to right coronary artery and saphenous vein autograft to the circumflex artery).
Internal mammary artery
grafts have a greater than 90% patency 10 years after CABG with only 1% demonstrating significant atherosclerotic stenosis.
Risk Factors for Sternal Complications Following Median Sternotomy * Obesity * Chronic obstructive pulmonary disease * Bilateral internal mammary artery
grafting * Diabetes * Re-thoracotomy * Canadian Cardiovascular Society Anginal Class * Number of transfused units * Smoking * Larger breast size in women * Prolonged cardiopulmonary bypass time * Prolonged mechanical ventilation time * Longer intensive care unit length of stay Table 2.

, the internal mammary bed, the internal periosteum of the sternum, the arteries around the xiphisternum, the leg after vein harvesting and cannulation sites.
