Figure 5. This black and white photograph shows the areas of degeneration in the former vascular equator produced by the fetoscopic laser occlusion of the connecting (anastomotic) blood vessels. The placenta was symmetrically shared by the twins. The laser surgery was performed at 20 weeks, with the 4lb. 5oz. and 3lb. 14oz. twin boys born 12 weeks later. (Photo courtesy of Dr. Julian E.
