The modified carbodissection technique is a new technique for harvesting the internal mammary artery during coronary artery bypass graft surgery. It is performed using an improvised instrument that consists of an electrocautery device and a carbon dioxide blower/mister. It combines electrocautery dissection and continuous controlled gas blow dissection along with saline irrigation mist. Gas dissection causes vasodilation and maintains the artery in a dilated state during dissection. Saline flow reduces the amount of heat generated at the cautery site and prevents drying and desiccation of the tissues. This technique is safe in terms of reduced thermal injury, and reduced early arterial spasm and myocardial ischemia, and it improves vision during harvest and shortens the duration of the harvesting procedure.
改良的碳凝解剖技术是冠状动脉搭桥手术中获取乳内动脉的一项新技术。该技术使用一种简易器械进行操作，该器械由电灼装置和二氧化碳吹风机/喷雾器组成。它结合了电灼解剖、持续可控气体吹拂解剖以及盐水冲洗喷雾。气体吹拂解剖可引起血管扩张，并在解剖过程中使动脉保持扩张状态。盐水冲洗可减少电灼部位产生的热量，并防止组织干燥和脱水。就减少热损伤、减少早期动脉痉挛和心肌缺血而言，该技术是安全的，并且它能改善获取过程中的视野并缩短获取手术的持续时间。
