Hunan hospital uses 3D printing technology to guide aneurysm surgery

Recently, under the guidance of 3D printing technology, the vascular surgery and radiology experts of Hunan Xiangya Hospital successfully performed abdominal aortic aneurysm surgery for an elderly person. According to reports, this is the first bold attempt of 3D printing technology in the clinical field of domestic vascular surgery, which helps to develop a more perfect surgical plan.

At the end of May this year, Mr. Wen’s 80-year-old man was found to have an abdominal aortic aneurysm during his examination at the hospital, and the situation was very critical. According to Huang Jianhua, director of the hospital's vascular surgery, the normal abdominal aorta is about 2 cm in diameter, but due to the swelling of the tumor, the blood vessel has now expanded to 6 cm. As the blood in the tumor continues to flow, the tumor may rupture at any time. As a result, the patient is likely to die.

Huang Jianhua believes that the traditional method is very traumatic to the patient for the treatment of the disease, and the postoperative recovery is slow. Before the operation, the vascular surgery experts of Xiangya Hospital cooperated with the 3D printing enterprise to convert the imaging data obtained by the CT scan to the refined data to obtain the accurate spatial data, which was transformed into a three-dimensional model and combined. 3D printing technology successfully printed the patient's abdominal aortic aneurysm and surrounding blood vessels in proportion to each other.

"3D printing technology allows doctors to fully understand the size, length, shape, angle, etc. of the tumor before surgery, so as to provide a reference for accurate selection of vascular stents, design of surgical plans, and development of surgical approaches, and predict the presence of surgery in advance. Difficulties." Huang Jianhua said.

Recently, the hospital vascular surgery experts successfully performed abdominal aortic aneurysm surgery under the guidance of 3D printing technology. Experts believe that 3D printing technology can eliminate the pre-operative "out of the air", out of the limitations of planarization to design a more perfect surgical program.

Phenibut HCL

What is Phenibut?

Phenytoin is a "brain stimulant" that has a variety of effects on the body and nervous system. A telepath is a drug that enhances memory or stimulates a specific area of the brain.

The report cites the I.M. Herzen-Leningrad Institute in the former Soviet Union as one of the earliest sites for synthesizing phenytoin. Russian space explorers took the form of this chemical to help them deal with the need for fenebbut to treat insomnia and in modern medicine, phenobarbital has lowered blood pressure and other related effects. It has some side effects, including the effects of drug withdrawal, increased blood pressure, anxiety and insomnia. Researchers are still studying how drugs like Fennebute can help better control neurological conditions.

It's also prescribed by doctors for people with specific symptoms a kind of anxiety, including social anxiety. It could even help treat other conditions, such as stuttering. In forums related to these conditions and pharmacology, individuals are attempting to educate the public about medicines. Before starting treatment with Fenebute or related medications, patients must be aware of the risks and benefits.

Consumer advocates point out that not all popular uses of these drugs have been specifically approved by the FDA, and that more attention may need to be paid to clinical trials. Government medical information sources have provided more information about the pharmacology of phenytoin sodium and information about the drug has reached the fitness community. Some people apparently believe that benibute is useful for athletes because of its relaxing properties. Fitness forums include reviews of the drug from individual users, including those who buy it over the counter.
