There is clear evidence that the internal mammary artery is superior to other forms of vascular conduit in surgical coronary revascularisation. Its patency rate at 10 years is of the order of 2-3 times that of autologous saphenous vein. Unfortunately, harvesting of the internal mammary is associated with an increased incidence of sternal wound complications, probably due to temporary sternal devascularisation. The restoration of sternal blood supply has been shown to occur after several weeks. It is proposed by this group that delayed primary closure of dehisced wounds after 3-4 weeks is an effective way of dealing with this malignant and, fortunately, rare complication of arterial coronary artery revascularisation.
有明确证据表明，在外科冠状动脉血运重建中，乳内动脉优于其他形式的血管管道。其10年通畅率约为自体大隐静脉的2至3倍。不幸的是，获取乳内动脉会导致胸骨伤口并发症的发生率增加，这可能是由于胸骨暂时缺血所致。胸骨血液供应已被证实在数周后会恢复。该研究团队提出，在3至4周后对裂开的伤口进行延迟一期缝合是处理这种严重且幸运的是罕见的冠状动脉血运重建并发症的有效方法。
