Aneurism is the pathological dilation of a blood vessel. The more frequent are the arterials due to Athrosclerosis although venous aneurisms also occur mainly in the profound veins like Iliac and Popliteal veins.
Within a dilated blood vessel a downsize in the flow velocity occurs as well as an increase in the pressure against the aneurism wall. As a consequence, the major complications of this condition are the Thrombosis (clot formation within the vessel) and rupture leading to Hemorrhage.
The complications as well as the symptoms will depend on the location of the aneurism. A brain aneurysm, for example, manifests its rupture with headache of sudden onset and variable neurological signs according to its location in the brain.
Here we will write about the Aortic Aneurysms. The more frequent arterial aneurysms are the Abdominal Aortic Aneurisms (AAA), Thoracic Aortic Aneurysm (TAA), Iliac, Popliteal and Carotid arteries aneurysms.
The aneurysm dilation are composed by all arterial layers. Similar to a party bladder, the bigger it gets the higher the risk of rupture, a life threatening condition. To avoid this complication it is necessary to correct this condition by means of open surgery or Endovascular approach.
The techniques and technologies used to the treatment depend on the local conditions and the specific characteristics of the patient and the aneurysm and shall be balanced by the physician.
After adequate analysis of all factors, we may plan the better strategy to the specific case.
As a preventive measure, the AAA shall be screened between 50 and 65 years of age.
