Which is the Most Serious Complication Of An Aortic Aneurysm?

Aortic aneurysm indicates a potentially dangerous condition that is usually fixed based on surgical procedure whenever any aneurysm size exceeds 5cm detected usually and measured with the help of ultrasound.

Mortality rates in case of open repair have become much better with the passage of time attributable towards drastic improvement in various operative techniques with pre as well as postoperative management of various patients.

Tears in Aortic Layers and Walls- Tears in one, two or more than two layers of the aortic or aorta dissection walls or a ruptured form of aortic aneurysm are the two major complications associated with the problem of abdominal aortic aneurysm.

Moreover, a ruptured form of aneurysm problem may result in life-threatening internal bleed. Generally, risk related to the rupture of aortic aneurysm increases with the increase in size of the aneurysm. Signs and symptoms associated with ruptured type of aortic aneurysm may include-

  • Sudden, persistent and intense back or abdominal pain, described usually as tearing sensation.
  • Pain radiating the legs and back
  • Clamminess and sweatiness
  • Nausea, dizziness and vomiting sensations
  • Fast pulse rate and low blood pressure.

Blood Clots- Blood clots are another major risk or complication associated with the problem of aortic aneurysm. Small blood clots may develop in the aortic aneurysm area. In case the break in blood clot looses from inner walls of the aneurysm and blocks the vessel of blood anywhere in the body, it may cause blockage or pain in the flow of blood to the toes, legs, abdominal organs and kidneys.

Complications of Surgical Procedure- There are many potential complications associated with abdominal aortic aneurysm repair in both open and endovascular types of surgical procedures. Complications taking place with surgeries such as bleeding and deep vein thrombosis sometimes become very much high and make the condition of patients highly severe.

The Complications Will Increase With Various Risk Factors

Complications associated with aortic aneurysm involve many risk factors, which include the following-

Age: Aortic aneurysm problem usually takes place in 65years age or more than that.

Tobacco Usage: Abdominal type of aortic aneurysm takes place in people with the bad habit of tobacco usage. Tobacco use in fact constitutes the strong risk factor associated with the development of any abdominal aortic aneurysm and has a huge risk related to rupture. In fact, the risk will increase with the number of cigarettes you smoke each day or chew tobacco for a long time.

Male/Men: Men usually develop much more problems or complications related to aortic aneurysm than women have.

White People: People, who belong to the category of white, remain at higher risk associated with aortic aneurysm.

Family History: People with a family history of the aortic aneurysm problem remain at increased risk related to the aneurysm problem or condition.

Atherosclerosis: Atherosclerosis i.e. the buildup of various harmful substances, including the fat components cause damages in the linings of one’s blood vessel and thereby, increase the risk related to abdominal aortic aneurysm.

High B.P or Blood Pressure: High B.P or blood pressure forms another major factor associated with increasing the risk related to development of the abdominal aortic aneurysm.

Other Aneurysms: People suffering from the problem of aneurysm in any other big blood vessel, such as artery present at the back portion of knees or thoracic aorta in chest stay at higher risk related to the development of abdominal aortic aneurysm.
