There have been no reports concerning wound healing at the site of the suture line in myxomatous leaflets. We microscopically studied the sutured wounds in two myxomatous posterior mitral leaflets which underwent quadrangular resection of the frail middle segment followed by primary suture. The sutured wounds had a thick scar which was abundant in collagen fibers about 1 month after the repair surgery. This suggests that severe myxomatous degeneration itself would not be a cause of wound dehiscence, and that a sutured wound could be a cause of rigidity and deformity of leaflets.
关于黏液样瓣叶缝合线部位的伤口愈合情况,目前尚无相关报道。我们对两片黏液样二尖瓣后叶进行了显微镜研究,这两片瓣叶接受了脆弱中间段的四边形切除,然后进行了一期缝合。修复手术后约1个月,缝合伤口处有一条厚厚的瘢痕,其中胶原纤维丰富。这表明严重的黏液样变性本身不会导致伤口裂开,而缝合伤口可能是瓣叶僵硬和畸形的一个原因。
