The emboli runs the way, the embolus runs the pathway

The emboli generally follow the direction of blood flow, and eventually stay at the blood vessels of comparable caliber and block blood flow. Embolus from different vascular systems operate in different ways.

1 Embolus of the venous system and right heart Embolus from the systemic venous system and the right heart enter the main trunk of the pulmonary artery and its branches with the bloodstream, causing pulmonary embolism.

Some small, elastic emboli (eg, fat emboli) can flow back into the left heart through the capillary vessels of the alveolar wall, and then into the systemic arterial system, blocking the small branches of the arteries.

2 Aorta.

Embolus from the aortic system and left heart emboli run with arterial blood flow and are blocked in the small arteries of various organs, commonly found in the brain, spleen, kidneys and the fingers and toes of the limbs.

3 Portal vein.

Embolus of the system Embolus from the portal venous system, such as the mesenteric vein, can cause embolization of the intrahepatic portal vein branches.

4 Embolus of cross-embolism Occasionally, emboli from the right heart or vena cava system reach the left heart through a congenital atrial (ventricular septal defect) and then enter the systemic circulation through a congenital atrial (ventricle) septal defect in the presence of increased pressure in the right heart.

The system causes embolism. Rarely, a small thrombus with a vein dislodged enters the systemic circulation through a patent pulmonary artery ductus and causes embolism.

5 Embolism of retrograde embolism is extremely rare in the inferior vena cava.

Internal thrombus, sudden increase in chest and abdominal pressure (eg, cough.

or deep breathing), the thrombus temporarily refluxes to the liver, kidney, and iliac vein branches and causes embolism.

The emboli run in the following way: frontal collapse.

1. Embolization of veins, right heart-pulmonary arteries and their branches.

2. Embolization of left heart and artery and systemic arteries and their branches.

3. Embolism of the portal venous system can cause intrahepatic portal vein branch embolism.

4. Cross embolism: It is common in atrial septal or ventricular septal defects in congenital heart disease, and the embolus is defected from the side with high pressure to the side with low pressure.

5. Retrograde embolization: the embolus in the inferior vena cava, when the intraperitoneal pressure in the chest and Jingyin increases suddenly, may run against the direction of blood flow and embolize the branch to which the inferior vena cava belongs.

The way of emboli operation is generally as follows:If it is a venous thrombosis, it will generally flow along the venous bloodstream, such as the iliac vein, the bone vein, it is to the heart, through the iliac vein to the inferior vena cava, that is, the thickest in our body, directly connected to the heart of the main road, the thickest vein all the way to the heart, and it will not stay in the heart, it will directly hit the pulmonary artery.

If it's large, it's what we call a pulmonary embolism; If the area is small, it will go all the way to the distal end of the particularly small pulmonary artery, and directly find a small pulmonary artery corresponding to its volume and diameter, and it will fall here, and then some autolytic protective mechanism of the human body will clean up the thrombus. If it is an arterial thrombosis, it is the same, but most of the arterial thrombosis originate from the heart, which is where the entire arterial system originates, and theoretically can affect all other branch arteries.

If it is a blood clot from the heart, it may travel down the carotid artery to the brain, causing a cerebral infarction. It may also reach the arm, causing embolism of the upper extremity arteries; or into the internal organs, Kaihong causes intestinal ischemia; After renal artery embolization, it will cause renal infarction and acute ischemia of the kidney; There is also a rush down the bloodstream to the distal end of the lower limbs, resulting in arterial ischemia of the lower limbs. Therefore, it is possible that it may spread in various places, but cerebral infarction and lower limb ischemia are relatively common.

The structure of the emboli is: the embolus (left and right structure) and the embolus (monomeric structure).

What is the specific explanation of the emboli, we will introduce it to you through the following aspects:

1. Explanation of terms [click here to view the details of the plan].

Plug shuānzi. (1) Foreign bodies or abnormal particles (such as air bubbles or blood clots) in the blood circulation will block the blood vessels and cause embolism.

2. Citations and Explanations.

A substance that blocks a blood vessel and causes embolism. Both thrombosis and foreign bodies can form emboli. See "Embolization".

3. Network Explanation.

Embolus refers to substances that block blood vessels during embolization. Common emboli in the practice of forensic pathology are thrombus, fat, air (bubble plugs), amniotic fluid, and bruised tissue, and occasionally tumor cell emboli. Embolus generally runs with the blood flow, and the route of operation has a certain regularity.

Embolus in the left ventricle and systemic arteries, eventually impacted in the arterial branches of comparable calibers; emboli in the systemic veins and right ventricle, embolization of the main trunk of the pulmonary artery or its branches; Embolism of the mesenteric vein, causing embolization of the intrahepatic portal vein branches. In patients with an atrial septal or ventricular septal defect, an embolus in the heart chamber can pass through the high-pressure side to the other heart chamber and embolize the corresponding arterial branch with arterial blood flow.
