With the change of lifestyle and dietary habits, the incidence of vascular diseases is increasing year by year. People know that cardiovascular and cerebrovascular disease is a major “killer” of human beings, but they do not know that there is a silent killer hidden in people’s stomach – visceral aneurysm. Since patients usually have almost no symptoms, visceral aneurysms are often found during occasional physical examinations, such as CT enhancement and other imaging tests, or the onset of symptoms – rupture of the aneurysm will be detected, so it is not an exaggeration to say that he is a silent killer. Visceral aneurysm is an important vascular disease that poses a serious threat to human health, and it can be said that such aneurysms are ubiquitous in people’s stomachs, with splenic artery aneurysms being the most common, most often in women. However, other visceral arteries can also develop aneurysms, such as: hepatic artery aneurysm, superior mesenteric artery aneurysm, abdominal trunk aneurysm, renal artery aneurysm and so on. The onset of visceral aneurysms is hidden, and most patients have no obvious symptoms, but are detected by routine abdominal ultrasound or arteriography. In a very small number of patients with large aneurysms, a pulsatile abdominal mass can be felt. Once abdominal pain develops, it may be indicative of a ruptured or impending rupture of the aneurysm. The greatest risk of visceral aneurysm is hemorrhage caused by rupture of the aneurysm, which has a high mortality rate; the second is the easy formation of thrombus within the aneurysm, and the dislodgement of thrombus leads to embolization of distal arteries, causing necrosis of tissues and organs in the area supplied by the corresponding arteries, e.g., splenic infarction, intestinal infarction. Because the disease is deeply hidden and not well known, ruptured visceral aneurysms are not always easy to diagnose and are easily confused with acute appendicitis, gallstones, pancreatitis, and other conditions. In recent years, the diagnosis rate of visceral aneurysm has become higher and higher due to the gradual improvement of physician’s vigilance and the progress of examination methods, and CT angiography can rapidly clarify the diagnosis. Therefore, once the diagnosis of visceral aneurysm is confirmed, most of them need active treatment. For those with small tumor, close follow-up observation and blood pressure control can be carried out; if the tumor is large or has a tendency to increase in size, decisive surgical treatment should be carried out. Doctor’s tips: Visceral artery aneurysm rupture is easy to cause hemorrhage, and its mortality rate is high; secondly, thrombus is easy to form in the aneurysm, and thrombus dislodgement leads to embolism of distal arteries, which causes necrosis of tissues and organs in the area of the corresponding artery supply, for example, causing splenic infarction, intestinal infarction, etc. Therefore, if you find yourself in discomfort, please contact us.
