#Thrombosis# is more common in veins than in arteries, because slowing of the blood-stream and irritation of the endothelium of the vessel wall are, owing to the conditions of the venous circulation, more readily induced in veins.
In the large veins, such as the internal jugular, the femoral, or the axillary, it is usually possible to suture the opening in the wall. This does not necessarily result in thrombosis in the vessel, or in obliteration of its lumen. When an artery and vein are simultaneously wounded, the features peculiar to each are present in greater or less degree.
Matas suggests infolding the wall of the vessel with interrupted sutures that do not pierce the intima, and wrapping it round with a strip of peritoneum or omentum. The most serious form of arterial thrombosis is that met with in the abdominal aorta, which is attended with violent pains in the lower limbs, rapidly followed by paralysis and arrest of the circulation.
Iliac Thrombosis. This condition is undoubtedly of more frequent occurrence than we are wont to grant when one considers the comparatively small number of cases that are actually recognized in practice. It does not follow, however, that iliac thrombosis rarely exists.
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.

In other cases thrombosis is associated with certain constitutional diseases gout, for example; the endothelium of the veins undergoing changes possibly the result of irritation by abnormal constituents in the blood which favour the formation of thrombi.
#Thrombosis.# The term thrombus is applied to a clot of blood formed in the interior of the heart or of a blood vessel, and the process by which such a clot forms is known as thrombosis. It would appear that slowing or stagnation of the blood-stream, and interference with the integrity of the lining membrane of the vessel wall, are the most important factors determining the formation of the clot.
Under these various conditions the formation of a thrombus is not necessarily associated with the action of bacteria, although in any of them this additional factor may be present. The most common cause of venous thrombosis, however, is inflammation of the wall of the vein phlebitis.
Some combinations, for example, result in a rapidly spreading cellulitis with early necrosis of connective tissue accompanied by thrombosis throughout the capillary and venous circulation of the parts implicated; other combinations cause great œdema of the part, and others again lead to the formation of gases in the tissues, particularly in the muscles.
