New technique of coronary artery bypass surgery: 5 hours surgery, ten years of good health

Department of Cardiology - University of Medicine and Pharmacy Hospital, Ho Chi Minh City, has just applied a new technique: bridging coronary arteries with 2 thoracic arteries, helping to clear 4-5 blockages at the same time; The lifespan of the bridge is about 10-15 years.

Mr. Do Van D. (55 years old, Go Vap) has been suffering from angina for the past 5 years, and often has to be treated with medication. But a month ago, Mr. had to go to the emergency room because of a heart attack. Through coronary angiography, the doctors discovered that the patient had narrowing of many coronary arteries.

One patient had multiple occlusions in the coronary arteries that could not be completely resolved by over-stent placement. Meanwhile, with traditional coronary bypass surgery using blood vessels in the legs or arms, after 5 years, 70% of these bridges will be re-obstructed.

Therefore, on October 5, doctors from the Department of Cardiology and Cardiology - Ho Chi Minh City University of Medicine and Pharmacy Hospital applied a new technique, coronary artery bypass with 2 thoracic arteries. One day later, the patient was extubated and was able to leave the care room.

Bridge "run well" 10-15 years!

Coronary artery disease is more and more severe, due to increasing favorable factors such as diabetes, high blood pressure, sedentary lifestyle,... Patients with coronary artery disease often have chest pain, chest heaviest, especially when exertion. Coronary artery narrowing due to plaque to a certain extent will cause patients to have erratic angina, possibly even leading to a heart attack.

BS. Nguyen Hoang Dinh - Head of Cardiovascular Surgery Department warned, "Patients with coronary heart disease are getting younger and younger. For cardiologists, patients under 60 are still 'young.'

For treatment, people usually put stents. But 10-15% of patients with coronary artery disease. Patients cannot have stents placed due to narrowing in many places, or because the coronary stenosis is in a rather special position, so when stenting can cause sudden death at that time, therefore, new cardiologists. using coronary bypass surgery."

Traditional coronary bypass is to take a healthy blood vessel such as the one in the leg or arm, or the left internal thoracic artery to make a bridge. But the question is, how long will this "bridge" last?

"After 5 years, 70% of the bridge by the saphenous vein in the leg will be blocked. The radial artery in the arm gives better results, but because the muscle is too thick, it can cause spasm. Meanwhile, the internal thoracic artery is good. 98% of the internal thoracic artery bypass is still open after 10-15 years.However

, for patients with too many stenosis, a left internal thoracic artery is not sufficient. With techniques from French cardiac surgeons, we applied multi-vessel coronary bypass with both left and right internal aorta," said Dr. Hoang Dinh said.

The internal aorta is the artery that feeds the chest. However, in this area there is a fairly dense vascular system, so the use of two thoracic arteries at the same time does not have a great effect.

The doctors will completely separate the right internal thoracic artery, and then make a Y-shaped connection with the left internal thoracic artery. Then these two Y-shaped branches surround the heart. The first branch of the left internal thoracic artery will be bridged through the most important occlusion. And the right thoracic artery will in turn connect through the narrowed coronary branches.

In the past 6 months, doctors here have performed 15 coronary surgeries, including patients with obesity and kidney failure. There are currently no cases of complications. This surgery can take about 5-6 hours. The cost for an operation is 65 million VND. For patients with health insurance, the maximum reimbursement is 20 million VND.

More easy childbirth morning intelligence?

Pregnant women with a lot of morning sickness may be relieved to know that feeling nauseous in early pregnancy is a sign that the baby will have a high IQ, according to a UK study.

Researchers have found that women who have a lot of morning sickness in the first weeks of pregnancy give birth to babies with more intelligence and better language skills.

4 out of 5 pregnant women experience morning sickness at the beginning of pregnancy. While there is no answer, some scientists hypothesize that morning sickness is caused by an increase in hormones that protect the fetus and placenta (the hormones thyroxine and human chorionic gonadotropin are secreted during pregnancy) morning).

Researchers at Children's Hospital Toronto believe that morning sickness is also linked to brain development in babies. 121 women who became pregnant between 1998 and 2003 were interviewed. Thirty mothers reported no symptoms of morning sickness, while the rest had symptoms such as fatigue, vomiting and nausea. The team then tested the IQs of children born to these mothers when they were between the ages of 3 and 7. Other factors such as the mother's IQ, smoking and drinking history The mother's alcohol consumption and education level were also considered.

“Children of mothers with morning sickness had higher IQs than children whose mothers had no symptoms during pregnancy. These children also had higher scores on language tests and in simple math," the researchers report in the journal Pediatrics.

The biggest flaw in this study is that morning sickness is just a recall of a time that happened a long time ago. In addition, the study also needs to be conducted on a larger group of subjects for the most accurate results.

Lead researcher, Dr Gideon Koren, admitted that the conclusions in this study may seem "a bit strange" but it is clear that hormonal changes in the body that lead to morning sickness in pregnant women are very good.

"Pregnancy hormones can cause discomfort for the mother, but on the other hand, they provide better development conditions for the fetus," says Dr. Koren.

According to statistics, about 50% of pregnant women have nausea and vomiting, only 28% have nausea but no vomiting during pregnancy. There is evidence that ginger and acupuncture can help alleviate these uncomfortable symptoms.

Previous studies have shown that nausea is a sign of a healthy pregnancy and a lower risk of heart problems and a lower risk of miscarriage.

In 2006, a study found that morning sickness is often increased due to the use of alcohol, meat, sugar and fat - which helps pregnant women to stay away from unhealthy foods.
