The mechanical role of thrombus on the growth rate of an abdominal aortic aneurysm. Does it increase or decrease the risk?

The maximum diameter is perceived to be the significant factor for the abdominal aortic aneurysms (AAAs). It is especially the case of the surgical repair. From the already existing studies it has been concluded that for the purposes of the rupture criteria the diameter is not be the reliable parameter. If it is the case of the stress regarding the individual patient, then it is intended to have the specificity as well as the sensitivity. For the growth of AAA, another important factor is related to the stress of the AAA wall. The current work is helping to get an insight of the wall stress on the intraluminal thrombus. Also, it is taking into consideration the growth rate of the aneurysms. For this purpose, both the patient specific AAA models as well as the idealized models are considered.

How is abdominal aortic aneurysm diagnosed?

Diagnosis:  Abdominal aortic aneurysms are often found during an examination for another reason or during routine medical tests, such as heart or the abdomen’s ultrasound. To diagnose an abdominal aortic aneurysm, doctors tend to assess your as well as your family medical history along with the physical examination.

In order to analyze the AAA models, the wall stress analysis can better be used. Incompressible linear as well as the elastic materiality is considered as the modelling for the Thrombus. The findings can better be compared for both the idealized models as well as the patient specified models (Speelman L, 2010). The regular therapies are desirable for the said purpose.

These are the main factors that make a rupture more likely:

·         The diameter of the aneurysm is larger than 5.5 cm.

·         The aneurysm has grown quickly (more than 0.5 cm in six months or more than 1 cm in one year).

·         The aneurysm is causing symptoms such as pain in the back, stomach, or sides.

Saturated fats are the cause of the increase of high level of cholesterol in the blood so food containing fats should be avoided.

The food that’s are that are highly saturate with fats are: sausages, fatty cuts of meat and sausages. All these high cholesterol foods are dangerous for the health and are the cause of pain in the chest, abdomen and the back. The mot dangerous risk that is associated with the aortic aneurysm is the potential rupture. Rupture of the muscles cause sever conditions to be happen in the body including the heart stroke or the internal bleeding.

If a person is diagnosed with thus disease, most of the doctors recommend the patients to void the heavy exercise and the physical activities because all these activities are responsible for the increase in the blood pressure and this will exert extra pressure on the aneurysm. Your blood pressure should be controlled. The need of daily exercise is necessary. But once this disease is diagnosed and it is developed along the aorta, the size of it will not reduce and it will not disappear. But some sort of medication is prescribed by the doctor for the slow growth of aneurysm. This disease does not have a cure. (Piechota-Polanczyk A, 2015)

To the wall stress the reduction has been caused by the thrombus. It has been found strong for both the moduli with higher elasticity & the larger thrombi. The diameter tends to have the remarkable stronger growth due to any of the AAAs which possess the large thrombus. It also provided with the considerable variations to the behavior of the patients. The overall impact has been visualized through the use of the ideal model along with the consideration of the variations.

conclusion of role of thrombus 

The higher growth rate of AAA tends to provide with the large thrombus in the AAA. The other significant provision is related to the lower wall stress. In case the wall stress shows more weakness to it, it shows the more significant role for the growth of AAA. All of it is done under the influence of the thrombus. For the said purpose the stress on the wall shows the less growth.
