one atherosclerosis

It usually occurs in the elderly over 50 years old, often accompanied by hypertension 、 coronary heart disease Etc.

2. Damage

It is often caused by sharp or blunt injuries.

3. Infection

Tuberculosis , bacterial endocarditis or Sepsis Bacteria can invade Arterial wall , leading to the formation of weak arterial wall Infectious aneurysm 。

4. Immune diseases

Non sensitive aneurysms are mostly caused by immune diseases, such as multiple Takayasu arteritis 、 Behcet syndrome Etc.

5. Congenital arterial wall Structural anomaly

as Marfan syndrome and Ehlers Danlos syndrome 。

clinical manifestation

According to the location of aneurysm, it can be divided into Peripheral aneurysm 、 Abdominal aortic aneurysm , chest Abdominal aortic aneurysm 、 Aortic dissecting aneurysm 、 visceral artery aneurysms Etc., mainly manifested as pulsating mass on the body surface and aneurysm compression peripheral nerve Or severe pain, thrombus in tumor cavity or plaque falling off at the time of rupture Arterial embolism Producing limbs and organs ischemia Or necrosis, etc.

one Color Doppler ultrasound examination It can determine whether there is aneurysm, the location and size of aneurysm, and can be used as the main method of screening and follow-up.

2. CTA can diagnose the aneurysm, and can determine the size and location of the aneurysm, its relationship with surrounding tissues, calcification of the artery wall, thrombus in the aneurysm, and the formation of ruptured aneurysm hematoma To provide more accurate information for further surgery.

three MRA The role of diagnosing aneurysms is roughly the same as that of CTA renal function Patients with damage can choose MRA at their discretion.

4. If the above three examinations cannot be diagnosed or the relationship between the aneurysm and other important arteries cannot be clearly identified DSA Check.

treatment

The treatment of aneurysms in different parts is different. The main treatment is surgical treatment Endovascular repair and embolization of aneurysms. The surgical principle was aneurysm resection and arterial reconstruction. Reconstruction methods include repair of artery rupture, artery Patch Inhibition and arterial end anastomosis Etc. The endovascular repair is covered with membrane Artificial blood vessel Endovascular repair of aneurysms with internal stents is minimally invasive and has a positive effect, but it must be strictly controlled Indications 。 For some visceral aneurysms, coil embolization can be used to Tumor body Thrombosis is formed inside the tumor body to avoid further expansion, rupture and bleeding.
