BIMA
Pronunciation: BY-ma
Also written as: BIMA — bilateral internal mammary artery
Use of both internal mammary arteries as arterial conduits in coronary artery bypass surgery.
Full Definition
BIMA grafting involves the use of both the left and right internal mammary arteries as arterial conduits in coronary artery bypass surgery. This technique provides superior long-term outcomes compared to single mammary artery grafting, with improved survival and reduced need for repeat revascularization. However, BIMA grafting is associated with increased risk of sternal wound complications, particularly in diabetic patients, and requires careful patient selection and meticulous surgical technique.
Usage
Usage note: Always spell out on first use; distinguish from LIMA and RIMA when used individually.
