In this case I am quite sure that what I have found indicates air in the arteries, the heart, and the blood vessels of the brain. It must have been a case of air embolism, insufflation." Though Everson seemed all along to have suspected something of the sort, Kennedy's judgment left him quite as much at a loss for an explanation.
Attention must be directed towards the condition with which the phlebitis is associated. Ligation of the vein on the cardiac side of the thrombus with a view to preventing embolism is seldom feasible in the peripheral veins, although, as will be pointed out later, the jugular vein is ligated with this object in cases of phlebitis of the transverse sinus.
#Entrance of Air into Veins Air Embolism.# This serious, though fortunately rare, accident is apt to occur in the course of operations in the region of the thorax, neck, or axilla, if a large vein is opened and fails to collapse on account of the rigidity of its walls, its incorporation in a dense fascia, or from traction being made upon it.
Rupture of a gastric or duodenal ulcer; rupture of liver, spleen, or extra-uterine gestation, or abdominal aneurism. Suffocation during an epileptic fit; vomited matter or other material drawn into the trachea or air-passages; croup. Arterio-sclerosis may lead to thrombosis, embolism, or aneurism.
FAT EMBOLISM. After various injuries and operations, but especially such as implicate the marrow of long bones for example, comminuted fractures, osteotomies, resections of joints, or the forcible correction of deformities fluid fat may enter the circulation in variable quantity.
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.
#Embolism.# The term embolus is applied to any body carried along in the circulation and ultimately becoming impacted in a blood vessel. This occurrence is known as embolism. The commonest forms of embolus are portions of thrombi or of fibrinous formations on the valves of the heart, the latter being usually infected with micro-organisms.
Moze surprised everyone, except possibly Mrs. Moze. As an unsuspected result of the operation upon her, an embolism had been wandering in her veins; it reached the brain, and she expired, to the great loss of the National Reformation Society. Such was the brief and simple history.
His method was still tentative and rude, and he divined in it all sorts of dangers, and especially, that of inducing embolism, if the liquor was not perfectly pure. Then he suspected that the strength of his patients came in part from the fever his treatment produced in them. But he was only a pioneer; the method would improve later.
Portions of malignant tumours also may form emboli, and their impaction in the vessels may lead to the development of secondary growths in distant parts of the body. Fat and air embolism have already been referred to. Pyogenic. Non-suppurative inflammation of the coats of an artery may so soften the wall of the vessel as to lead to aneurysmal dilatation.
