The world's first!No trace!The 2 -year -old Wuhan boy installed the "full degradation room interval blocking device"

The Yangtze River Daily Da Wuhan Client August 9th (Reporter Wang Chunlan Correspondent Xue Yuan) On August 4, a 2 -year -old Wuhan boy underwent heart surgery "replenished the heart". Enter a blocking device. Different from the past, this surgery is not a traditional metal material blocking device, but the latest full degradation room interval blockage block. One year later, the blocking device will be completely degraded and decomposed into carbon dioxide and water discharge from the body. There is no foreign body in the body to achieve "nourishing the heart" without leaving traces.

Congenuction boy is packed with "fully blocking block"

The boy is a native of Wuhan every day (pseudonym). When he was 7 months old, he was found to have a small defect in the interval between the heart chamber. After observing more than a year, the defect increased to 4.1 mm.

Parents take the medical treatment at Wuhan Children's Hospital every day. The doctor judges that as the child's weight continues to increase, the heart load will become larger and larger, affecting cardiopulmonary function and growth and development. Zhang Yong, director of the Department of Cardiovascular Medicine of the hospital, suggested that minimally invasive intervention in the treatment.

On August 4th, Zhang Yong led the surgery team to perform surgery every day. Under perspective and ultrasound guidance, he pushed the transmitted tube and blocking device to the heart development defect of the heart after piercing the outer peripheral blood vessels at the root of the thighs. Cover the defect.

After surgery, the child's heart "gap" was blocked, the blood was no longer diverted, and the treatment effect reached expectations. The next day after the operation, I went to bed every day and was discharged from the hospital on August 8.

"Nourish the heart" without leaving marks, it can also reduce hidden dangers

Zhang Yong introduced that room interval defects are common psychological diseases. At present, intervention sealing is the first choice for treating room interval defects. It has a small trauma and fast recovery.此前广泛使用的传统镍钛合金封堵器，安全、可靠、有效，但会永久存留在患者体内，由于个体差异的存在，极少数孩子可能出现镍过敏、心脏传导阻滞等不良反应，以及在The magnetic resonance inspection of more than 3.0T or more after surgery is not performed.

The world's first full degradation room interval blockage device recently listed in the world uses biodegradable materials. After implanting the human body, it can build a "temporary bridge" for the defect. Growing on the block. After the myocardial cells are completely covered with defects, the blocking device begins to gradually degrade and breaks down into carbon dioxide and water to discharge the body.

It is reported that the full blocking device system was independently developed by Chinese enterprises. After being approved to be listed, Wuhan Children's Hospital became one of the first hospitals to be applied to clinical hospitals. This marks the new stage of "intervention without implantation and no marks".

"Degradable" is getting closer and closer to us

As early as the listing, the hospital in my country was trying the "degradable room intervals defect block" surgery. The earliest dates back to February 2, 2018, the National Cardiovascular Center Composite Technology Team successfully completed the world's first "completely frozen -frozen blocking device".

After being approved to be listed on the listing system, two experts from Fuwai Hospital in July this year, in Beijing and Zhengzhou, applied the same models of unbocrust device to successfully treat them with three congenital heart disease children. The intervals of the interval.

"Devitar materials are of great significance to the development of congenital heart disease treatment technology." Professor Shen Qunshan, a heart expert of Wuhan Asian Heart Hospital, believes.

According to him, as one of the clinical trial units, in 2019, the hospital has implemented the first "degradable ovarian round hole unatient blocking device" in Central China. The originally implanted blocking device had no traces. A total of 30 cases were performed at the time, and the follow -up follow -up effect was very satisfactory.

The reporter of the Yangtze River Daily found that it has brought about the long -term impact of traditional metal materials, in recent years, "degradable" materials have explored the ascendant. Many medical companies have degraded vascular stents, degradable urethra stents, degradable water decomposition water. Research on gel, degradable fracture fixed materials, etc., some products have been listed.
