Hypertension can cause sinister aortic dissection
Not long ago, a male elderly person with high blood pressure in Shanxi for ten years, because of sudden acute chest and abdominal pain, can not be supine, diagnosed as a descending aortic head aneurysm in a specialist hospital, abdominal aortic closure, due to inoperability andCatheter implantation can only be treated conservatively.
However, the family members of the patient hope to come to Beijing Anzhen Hospital and find Professor Sun Lizhong, director of the Beijing Large Blood Vessel Diagnosis and Treatment Research Center.
After seeing the patient’s CAT film, Professor Sun knows that the patient is critically ill, but there is still a glimmer of hope that surgery must be performed as soon as possible, otherwise life is at risk.
While the family rushed to the Shanxi patient, Professor Sun Lizhong directed a group of personnel to prepare for emergency surgery.
When the patient rushed to Beijing, his lower limbs had been severely dilated, unable to move, and his right lower limb was pale.
The emergency department entered the catheter room and was successfully performed by Huang Lianjun and Professor Fan Zhanming.
Interventional patients were better every day. The angiography showed that the occluded blood vessels were clear, and the lower limbs recovered blood supply without leaving any sequelae.
According to reports, the patient’s lower limbs have no blood, a kidney failure, if there is no hope for another night.
There are few people in this kind of surgery who dare to do it.
■ Long-term hypertension or arterial wall atherosclerosis and arterial wall congenital elasticity decline, leading to the most critical cause of large blood vessels It is understood that the main cause of aortic dissection is hypertension.
Due to the large population base with high blood pressure, the age of onset tends to be younger. In particular, a considerable number of patients must strictly abide by the doctor’s advice to control hypertension, so that the proportion of aortic dissection is significantly higher than that of Europe and the United States.
Due to the high mortality rate of the aortic dissection, and the acute onset of domestic patients at 40-50 years old, it has caused a serious burden on families and society.
Focusing on the aortic dissection requires knowledge of major vascular disease.
The large blood vessels refer to the ascending aorta, the aortic arch, the descending aorta and the abdominal aorta, which are directly emitted by the heart, and are the main line of blood circulation of the human body.
Macrovascular diseases include dilated aortic disease and stenotic aortic disease. The former mainly includes aortic dissection, aortic true aneurysm and aortic pseudoaneurysm.
The aortic dissection is aortic intimal tear. The aortic cavity is driven by blood pulse pressure to enter the middle layer of the aortic wall through the intimal tear. The aortic wall is separated and forms a false cavity, which is a fatal and extremely high acute.Vascular disease.
The etiology and pathogenesis of aortic dissection are not well understood.
It is currently recognized that long-term hypertension or arterial wall atherosclerosis or congenital elastic loss of the arterial wall is the cause of aortic dissection.
It is the most critical alternative to macrovascular disease.
■ The treatment of macrovascular diseases has made great progress. It can replace the improvement of diagnostic techniques and the continuous advancement of medical technology. The diagnosis and treatment of macrovascular diseases have made rapid progress.
At present, the treatment of macrovascular diseases includes artificial blood vessel replacement, endovascular replacement of stent graft and cross surgery.
Due to the continuous enrichment of clinical experience in large blood vessel diseases and the continuous improvement of technology, the original surgical exclusion zone has been broken one by one, and the complications of surgery have also been greatly reduced.
In particular, the presence of stent-like nasal surgery has significantly reduced the mortality of aortic surgery, and the quality of life after surgery has been significantly improved.
Large vessel stent grafts were used clinically in the late 1990s.
Because of its small trauma, good therapeutic effect, implant healing is one of the important means of treatment of macrovascular diseases.
■ On-time medication for high blood pressure can effectively prevent the occurrence of severe vascular crisis. Hypertension is the main cause of dilated large vascular disease.
Long-term increase in blood pressure increases the pressure load on the aortic wall, increasing the risk of aortic dilation or rupture.
Therefore, timely physical examination, timely detection of hypertension, timely medical treatment, timely medication is an important method of hypertension treatment, but also the primary factor in preventing the occurrence of severe vascular crisis.
Macrovascular disease is a very dangerous disease with acute onset, poor prognosis, and high mortality. It occurs in patients with a history of hypertension, so hypertensive patients should actively and effectively control blood pressure.
In the event of retinal chest or back pain, you should seek medical advice promptly, and you should not delay the timing of diagnosis and treatment.
