"Hey, hey, can you hear me?" Zheng Ren's voice came from the loudspeaker."Doctor Zheng, I can hear you. Please speak." Chief Jiang was also dumbfounded. Not only could this Doctor Zheng perform embolic surgery, he could also perform embolic opening surgery so smoothly!If he could perform an opening surgery, he would definitely be more amazing if he were to perform a circulatory intervention. There was no need to even think about it.Therefore, Chief Jiang immediately knelt down. His tone was more respectful and admiring than the gratitude he used to have."Oh, Chief Sun, the blood clot has been removed. When you perform the surgery, you can try to preserve the parts below the knee joint," Zheng Ren said. "I'll wait for ten minutes before radiographic films will be sent to you."Zheng Ren said it very simply. He needed to wait for ten minutes for the capillaries to reopen. Then, he wanted the orthopedics department to determine if a certain part could be preserved.
