A traumatic aneurysm is almost always sacculated, and, so long as it remains circumscribed, has the same characters as a pathological sacculated aneurysm, with the addition that there is a scar in the overlying skin. A traumatic aneurysm is liable to become diffuse a change which, although attended with considerable risk of gangrene, has sometimes been the means of bringing about a cure.
An aneurysm may prove fatal by exerting pressure on important structures, by causing syncope, by rupture, or from the occurrence of suppuration. Pressure symptoms are usually most serious from aneurysms situated in the neck, thorax, or skull. Sudden fatal syncope is not infrequent in cases of aneurysm of the thoracic aorta.
#Popliteal Aneurysm.# This is the most common surgical aneurysm, and is not infrequently met with in both limbs. It is generally due to disease of the artery, and repeated slight strains, which are so liable to occur at the knee, play an important part in its formation. In former times it was common in post-boys, from the repeated flexion and extension of the knee in riding.
When an artery is wounded a firm hæmatoma may form, with an expansile pulsation and a palpable thrill whether such a hæmatoma remains circumscribed or becomes diffuse depends upon the density or laxity of the tissues around it. In course of time a traumatic arterial aneurysm may develop from such a hæmatoma.
The Moore-Corradi method consists in introducing through the wall of the aneurysm a hollow insulated needle, through the lumen of which from 10 to 20
As the sac of the aneurysm includes all three coats, and as the inner and outer coats are usually thickened by the deposit in them of connective tissue, this variety increases in size slowly and seldom gives rise to urgent symptoms.
This laminar coagulation by constant additions gradually fills the aneurysmal cavity and the pulsation in the sac then ceases; contraction of the sac and its contents gradually takes place and the aneurysm is cured.
Such a vessel also is liable to be ruptured by external violence and so give rise to traumatic aneurysm. Thrombosis is liable to occur when calcareous plates are exposed in the lumen of the vessel by destruction of the endothelium, and this predisposes to embolism.
The aneurysm is usually of the sacculated variety, and may spring from the front or from the back of the vessel. It may exert pressure on the bones and ligaments of the joint, and it has been known to rupture into the articulation. The pain, stiffness, and effusion into the joint which accompany these changes often lead to an erroneous diagnosis of joint disease.
The continuity of the artery may be restored by grafting into the gap left after excision of the sac a segment of the great saphena vein. Ligation of the Artery. The object of tying the artery is to diminish or to arrest the flow of blood through the aneurysm so that the blood coagulates both in the sac and in the feeding artery.
