368 MORBID ANATOMY.
defined, rounded dilatations, and varying in size from nearly two to six. lines. They involve, generally, a portion only of the circumference ; and, to some extent, the sacs were situated regularly along one side of the vessel. The pari- etes of most of them were thick, hard, and cretaceous ; the cavity being more or less encroached upon, and in some nearly obliterated, though in a few it was well marked. Otherwise the artery was healthy, as was the spleen itself.
From an old woman, who died of ileus. 1856.
Dr. C. Ellis.
I have met with the above disease of the splenic artery quite a number of times, and am not aware that it has been described, if even noticed. It seems to be not very uncom- mon, and will probably explain the cases of phlebolites in the splenic vein that are occasionally referred to. (Med. Jour. Vol. LVI. p. 297.)
1803. A second specimen ; dried. One sac ossified, and very greatly thickened where it has been cut through.
From an old woman, who died of cancer. 1859.
Dr. G. Ellis.
1804. A third specimen ; in spirit ; from the same patient as the last. Dilatation and ossification of the parietes of the artery are just commencing. 1859. Dr. C. Ellis.
1805. A fourth specimen ; cut open and showing a small and quite defined aneurism, the parietes of which are ossified. From an old woman who died of pneumonia. 1861.
Dr. D. W. Cheever.
1806. Aneurism of the right common iliac artery, about the size of a goose-egg ; cut open, and shows that it is formed, mainly at least, by a dilatation of the parietes ; also that it is filled with coagula. A small portion of the aorta, just above the sac, is seen to be diseased ; and the ext. and int. iliacs just below it are dilated.
From a man who died of apoplexy. (Hospital, 251, 78.) 1862. Dr. C. Ellis.
1807. A defined, rounded, aneurismal tumor, about as large as the fist, and situated at the left groin ; the external iliac having been tied by Dr. W. One-half of the pelvis has been preserved, and the arteries, with the sac, are injected.
