Aneurysm - symptoms and types

Aneurysm symptoms

Defines aneurysm as a Permanent dilation of an area of the artery wall that has undergone previous alterations.

The aneurysm occurs in the aorta, but can also be located in any other artery: the neck carotid, the popliteal (of the posterior Fossa of the knee), aneurysm, brain, or in the intestine of the mesenteric artery, etc.

Types and causes of aneurysms

Aneurysms can be divided into three groups: true, disecantes and spurious or false aneurysms.

True aneurysms are those in which the arterial wall is altered in its structure and therefore weakens (without breaking) in a more or less limited area by the pressure exerted by the blood that flows through the glass.

Some diseases such as tuberculosis, syphilis or atherosclerosis may be as the origin of this type of aneurysm; Erosive process, trauma, etc. also represent the most common of this type of aneurysm causes. (This type of aneurysm is called fusiform (by its form of spindle), sacciforme for his SAC in communication with the light of the glass by a narrowed area called neck), etc.

The dissecting aneurysm is called so because the layers more internal, intimate media, blood, instead of being weak wall is broken and, therefore, blood is infiltrated by the area destroyed, separating and dissecting the inner layers of the artery of the external, which remains full, dissecting the latter of those.

In this type of aneurysm, the cause is usually a trauma and the consequences are the breakdown of the innermost layers of the artery. When the wound of a sharp object or a firearm, or by erosive process of the arterial wall, the three layers are broken and the blood is contained by a cohesive layer of new training, then refers to an espúreo or False aneurysm.

Aneurysm symptoms

Superficial arteries aneurysms

In the case of the superficial arteries aneurysm is diagnosed by palpation: by feeling the swelling that causes the aneurysm warns its soft consistency and its rhythmic expansion in synchronization with the arterial pulsations. This is due to the blood entering the aneurysmal SAC during cardiac systole.

Deeper aneurysms - Aórtico

In deep, as the aortic aneurysms, is needed an x-ray or CT scan of the chest, or echocardiography to discover the presence of the aneurysmal SAC. Aortic aneurysm, which is the most common and can be caused by:

  • Syphilis
  • Ateriosclerosis
  • High cholesterol
  • Inflammation of the aorta
  • Injuries, etc.

The aneurysm is diagnosed by the following symptoms:

  • Type angina pectoris pains
  • Spastic cough
  • Dyspnea
  • Arterial hypotension
  • Swollen neck
  • Problems swallowing
  • Sore back, etc.
