Celiac trunk aneurysm
Introduction
Introduction to abdominal dry aneurysms Celiac axis aneurysm (celiacaxisaneurysm) refers to an aneurysm that occurs in the distal part of the celiac trunk artery, accounting for 4% of all visceral aneurysms in the body. By 1985, there were less than 108 cases reported in the world literature, and 9 cases were successfully treated in Shanghai Zhongshan Hospital. In the middle age, the current male-female ratio tends to be equal. basic knowledge The proportion of illness: 0.008% Susceptible people: more than middle-aged men and women Mode of infection: non-infectious Complications: shock
Cause
Cause of celiac trunk aneurysm
(1) Causes of the disease
Common causes of abdominal aortic aneurysms are medial degeneration with arteriosclerosis, followed by trauma, infection, and congenital factors, as well as syphilis.
(two) pathogenesis
The celiac trunk aneurysm mainly involves the distal end of the celiac trunk artery, usually a saccular aneurysm.
Prevention
Celiac trunk aneurysm prevention
There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.
Complication
Complications of celiac aneurysm Complications
Aneurysm rupture is the main complication. In recent years, the rupture rate is 15%, and the probability of death from massive bleeding after rupture is about 50%.
Symptom
Symptoms of celiac trunk aneurysm Common symptoms Jaundice shock Gastrointestinal bleeding Abdominal pain Nausea
Most of the abdominal abdomen aneurysms have no symptoms. A few can be manifested as upper abdominal pain and discomfort to the back. They are often mistaken for pancreatitis or peptic ulcer disease. In 1976, Haimovici et al reported a case of celiac trunk aneurysm with symptoms similar to ulcer disease. Partial gastric resection, abdominal pain does not relieve, relieve pain after resection of aneurysm, aneurysm rupture caused by intra-abdominal hemorrhage, first into the small omental sac, and then into the peritoneal cavity, at this time there may be upper abdominal pain accompanied by nausea and vomiting And back pain, upper abdominal pain, pulsatile mass, gastrointestinal bleeding, shock, and occasional obstructive jaundice, often the performance of celiac trunk aneurysm rupture.
Examine
Examination of abdominal dry aneurysms
B-ultrasound, SCTA, and MRA are helpful for diagnosis. Due to the extensive application of angiography or DSA, the discovery of celiac aneurysm is increasing. Arterography and DSA are the most reliable methods for diagnosing celiac aneurysms.
Diagnosis
Diagnosis and diagnosis of celiac trunk aneurysm
Preoperative diagnosis of celiac trunk aneurysm is difficult, mainly relying on angiography.
